[0:39] <FunkyELF> Is the raspberry pi's HDMI able to connect to DVI via a passive dongle?
[0:39] <mgottschlag> yes
[0:40] <mgottschlag> hdmi always has dvi-compatible signalling
[0:40] <FunkyELF> okay... but not the other way around right?

[0:42] <mgottschlag> I am sure that cheap solutions exist to do that as well
[0:42] <FunkyELF> I'm looking at getting a new monitor because it is inconvenient for me to use the TV
[0:42] <FunkyELF> oh... I think I was thinking of display port. There are passive adapters that go one way but to go the other way is a pain. I forget which

[0:44] <FunkyELF> I got the DELL U2713HM which has great connectivity. It has DVI for my workstation, VGA for my work laptop, and HDMI for my raspberry pi.... but I need to return it because of quality issues on the screen.
[0:44] <FunkyELF> I'm looking at the U2312HM but it doesn't have HDMI
[0:44] <FunkyELF> it has DVI, Display Port, and VGA
[0:45] <FunkyELF> Can the rpi send out a Display Port signal over HDMI? I'm wondering if one of these $10 adapters would work
[0:47] * m8 (~mor@unaffiliated/m8) Quit (Quit: Sto andando via)
[0:49] <mgottschlag> just as hdmi just happens to be compatible, it probably is compatible to displayport if adapters exist
[0:49] <mgottschlag> so a normal hdmi signal would also be a valid displayport signal (maybe with very subtle differences)

[0:51] * BaroMeter (~BaroMeter@h158n11-sde-d2.ias.bredband.telia.com) Quit (Client Quit)
[0:52] <AndrevS> are you saying there is no difference between hdmi and displayport but the connector?
[0:52] * BaroMeter (~BaroMeter@h158n11-sde-d2.ias.bredband.telia.com) has joined #raspberrypi
[0:52] * DarkKnightCZ (~lukas@ip-4-11.hlucinnet.cz) Quit (Ping timeout: 246 seconds)
[0:52] <mgottschlag> I am saying that *if* adapters exist, then the differences are small enough so that the signal usually is compatible
[0:53] <FunkyELF> oh... nevermind
[0:53] <AndrevS> Well... I am seeing strange adaptors on the internet.....
[0:53] <AndrevS> VGA to composite for example
[0:53] <mgottschlag> there will be huge differences in terms of additional capabilities and control signals though
[0:53] <FunkyELF> All the adapters I found were for DP -> HDMI.... not the other way around. The HDMI -> DP adapters are active and $$$
[0:53] <mgottschlag> VGA to composite indeed sounds a little bit strange :D
[0:54] * Yen (~Yen@ has joined #raspberrypi
[0:54] <mgottschlag> although it would be possible with some passive circuitry and a graphics card which outputs very weird vga resolutions/frequencies
[0:55] <AndrevS> It could be done, if you have enough control over the hardware.
[0:56] <AndrevS> but you need to get the sync on there.... but I've read about sync-on-green, so that might work

[0:57] * rolleiflex (~rolleifle@ has joined #raspberrypi
[0:57] <mgottschlag> I still want to try to output VGA signals using the rpi GPIO pins one day.
[0:59] <AndrevS> Are they fast enough?

[1:00] <AndrevS> I think you'll need real-time for that. Unless timing for GPIO can be gone in hardware.
[1:00] <AndrevS> Otherwise, just a D-A converter, level shifter,
[1:00] <mgottschlag> well, you have enough rt capabilities if you hack a small kernel :)
[1:01] <mgottschlag> and it won't be fast enough for full 640x480, but still, just because it is possible :D
[1:01] <mgottschlag> (I think people reported sth like 20MHz signals on the GPIO pins)

[2:44] <shiftplusone> lkthomas, http://lizarum.com/assignments/physical_computing/2007/breadboarding.html
[2:44] <shiftplusone> If you don't need it anymore, put it in a drawer until you do... dev boards and breadboards often come in handy.

[2:50] <lkthomas> shiftplusone: is that a "standard" board structure ?
[2:50] * spY|da (~spychodel@ Quit (Ping timeout: 248 seconds)
[2:50] <shiftplusone> Yeah, sometimes the collumns on the sides may not run through the whole board but be split in two or more sections, but in general that's all there is to it.

[2:53] <shiftplusone> The basic idea doesn't change. It's deisgned to run power on the side collumns (5v and gnd lines or whatever the case may be). Dual inline packages (DIP) slot into the center. Then use wires, resistors and whatever else you need to connect everything.
[2:54] <lkthomas> sorry, I don't have much wiring knowledge
[2:54] <lkthomas> does Pi header is pin to pin connector ?
[2:55] <shiftplusone> I am not sure what you mean
[2:55] <lkthomas> http://learn.adafruit.com/assets/1866
[2:55] <lkthomas> it have a Pi header connect back to Pi
[2:55] <shiftplusone> I've got to go, but someone else will help you out if you stick around for a bit.
[2:55] <lkthomas> thanks mate
[2:55] <shiftplusone> take care
[2:57] <FunkyELF> so I bought two of these. When connected to my Raspberry Pi one of them reads 4.83 while the other reads 4.91. The one with 4.83 causes keyboard problems. Why would that be? Isn't 4.83 within range for the Raspberry Pi?

[2:57] * spY|da (~spychodel@linuxjunkies.de) has joined #raspberrypi
[2:57] <FunkyELF> keys seem to be stuck in the down position repeating over and over again... missed keypresses also happen
[2:57] <shiftplusone> It may be within tha range of the pi, but outside the range of the keyboard.
[2:57] <john_f> same cable?
[2:58] <shiftplusone> I have a keyboard that's sensitive to voltage levels as well and does the same thing
[2:58] <FunkyELF> john_f: shiftplusone same exact setup. same cable / keyboard

[3:00] <shiftplusone> FunkyELF, nope
[3:00] <john_f> errant enter key,
[3:00] * shiftplusone is gone
[3:01] <john_f> lkthomas: the breakout in the pictures is just the pins from the cable spread out
[3:01] <john_f> doesn't do anything to them electrically
[3:01] * FunkyELF doesn't like that adafruit doesn't really have a way of dealing with exchanges/returns. You basically have to post in their forum
[3:02] * Syliss (~Home@ has joined #raspberrypi
[3:02] <lkthomas> ok, just wonder if the Ribbon cable did some cross over connection
[3:02] * spY|da (~spychodel@linuxjunkies.de) has joined #raspberrypi
[3:02] <john_f> not meant to connect two pi's afaik
[3:02] <john_f> so no crossover

[3:04] <lkthomas> john_f: does GPIO ribbon is a standard?
[3:04] <lkthomas> just wondering if I have to get it from adafruit
[3:04] <john_f> just standard idc with the correct number of pins
[3:05] <lkthomas> so the number of pins also fixed
[3:05] <john_f> many sizes of idc, like used in floppy drives
[3:05] <john_f> different pin count

[3:07] <john_f> yes you can

[3:09] <pksato> first, build a protection board.
[3:09] <aDro> how do
[3:09] <lkthomas> pksato: how ?!
[3:09] <lkthomas> is that possible not to involve "board" ?
[3:09] <aDro> How do i list help by page?
[3:10] <lkthomas> I want to build everything within Pi case
[3:10] <aDro> or list terminal results by page?
[3:10] <pksato> not board?

[5:40] <gh403> my bad ;)
[5:40] <xiambax> I ordered my raspberry pi lastnight after waiting for 6 months to just order one
[5:40] <bbond007> no, its a 68K Mac emulator
[5:40] <xiambax> I didn't want to wait a two months for it to ship though :(
[5:41] <xiambax> So I amazon'd it
[5:41] <bbond007> i ordered mine from MCM right when the 512 ones were anounced... it came in just a few days
[5:42] <gh403> I saw the 512MiB ones get announced, then I waited a week to be darn sure that I'd get the good ones. It was around Christmas by that point anyway.
[5:43] <xiambax> I bought a new router yesterday and setup ipv6 lastnight
[5:43] <xiambax> that router is sick and i caved and bought a domain and got hurricane electric to host my dyndns
[5:43] <gh403> My Pi is sitting on a little $8 Cisco switch here on my desk. The blinkenlights are a great comfort to me ^_^
[5:44] <xiambax> so i think i want to turn my rpi into a ipv6 and ipv6 web server.
[5:44] <xiambax> I have yet to decide what distro i want to install
[5:44] <gh403> I really want to 3D print a case for it; I know this guy with a 3D printer. Anybody have opinions on which cases are the best?
[5:44] <bbond007> ah, crap, bubble trouble locked up the emu
[5:45] <gh403> xiambax: Arch
[5:45] <gh403> xiambax: the hard part (installing it) is even done for you already ^_^
[5:45] <xiambax> I want something stripped
[5:46] <gh403> Arch is pretty bare.
[5:46] <xiambax> It's just going to be a file share and web server
[5:46] <gh403> You get a command prompt, and the GNU utilities, and the pacman package manager, and that's about it. YOU choose what your system will become.

[5:49] <xiambax> What do you use it for?
[5:49] <gh403> I program it to do things like watch websites for me and email me if something shows up (these sites don't have RSS feeds).
[5:49] <gh403> Basically anything that requires a periodic check, but not much processing power.
[5:50] <gh403> I'm also thinking of spinning up an owncloud instance on it.
[5:50] <gh403> Although that might be overkill; I don't know.

[5:54] <xiambax> and then it route subdomains to ips behind my router
[5:54] <xiambax> can that be done

[5:57] <xiambax> yes, ipv6 allocated too
[5:58] <gh403> Hm, with NAT you can't do that. All your machines look like one IP address to the outside network. But with ipv6, it might be possible; I don't really know. I do know that you'll have to have an ipv6-compatible remote connection to be able to access it.

[5:59] <Viper-7_> xiambax: you need a load balancer or reverse proxy, it can be internal to your network (proxying requests based on vhost directly to the appropriate server) or external (proxying requests to a specific port on your external IP, which you can then NAT and translate to port 80 on the server you want)
[5:59] <piney0> i would use nginx or some other reverse proxy on the external ip address to route the traffic to the other addresses.

[7:03] <Torikun> think I need more than 16mb split?
[7:03] <dr_willis> you got 16mb for the video?
[7:03] <Torikun> yup
[7:03] <dr_willis> that seems very very low.
[7:04] <dr_willis> like 1975 dos days low. ;)

[7:04] <TAFB> dr_willis: hehe. Decoder came from China, it's not listed as decoder, but works damn sweet ;)
[7:04] <Torikun> that maybe the problem lol

[7:27] <Torikun> and arch has newer packages
[7:28] <aDro> I am trying to learn arch after first learning how to manipulate around ubuntu and raspian
[7:28] <Torikun> arch is pretty awesome

[7:29] <Torikun> im having a few build and vnc issues with it at the moment lol they seem to be unique to me
[7:29] <SwK> now if I could just figure out how to hack the hardware to have a SSD inplace of the SD and I would be happy lol
[7:30] <SwK> (yes I know that kinda defeats the purpose of having a sub $50 nearly complete system but still)
[7:30] <Eliatrope> I had some kernel errors in Arch, even with Raspbian's kernel
[7:30] <Eliatrope> maybe it was low voltage issue, but I have 4.8V now
[7:31] <Eliatrope> errors when accessing both network and SD card with heavy load
[7:31] <TAFB> 4.8 is the super bare minimum you should get. Check the voltage DURING bootup and see if you get any drops.
[7:32] <TAFB> If so, you might need to bridge/bypass polyfuse F3 or upgrade to a better quality MicroUSB cable or higher power USB power supply (you can't power the Pi from the computer).
[7:32] <Eliatrope> I didn't get errors on boot
[7:32] <Eliatrope> I heard heard IPad's charger is good, but I had 4.6V with it
[7:32] <TAFB> Best quality microUSB cable on earth: http://www.monoprice.com/products/product.asp?c_id=103&cp_id=10303&cs_id=1030307&p_id=8641&seq=1&format=2

[13:45] <Ryanteck> and you can get chips that connect via pin out to get more pins if needed
[13:45] <Ryanteck> I think
[13:45] <lkthomas> isn't it will be full soon ?
[13:45] <lkthomas> sorry, I don't get it
[13:45] <Ryanteck> Neither do I fully
[13:46] <Ryanteck> Not had the chance to buy components for hardware
[13:46] <lkthomas> right
[13:48] <Amadiro> lkthomas, with I2C, I think you can attach up to 128 components or so
[13:48] <lkthomas> so bascially 128 modules will be connect into 26 pins ?
[13:49] <Amadiro> lkthomas, the I2C bus only needs two wires.
[13:49] * mumbles (~mumbles@habari/community/mumbles) has joined #raspberrypi
[13:49] <mumbles> forgot to add this to auto join
[13:49] <lkthomas> ok, so how does two pin connect 128 devices ?!
[13:49] <lkthomas> is there have a mulplexer or something ?
[13:50] <Amadiro> lkthomas, I2C is a serial bus
[13:50] <Amadiro> only one device can talk at any time to the host
[13:50] <Amadiro> its a similar deal with SPI
[13:50] <lkthomas> what if two or more module want to talk to host ?
[13:50] * jprvita|afk is now known as jprvita
[13:51] <Amadiro> lkthomas, one of them has to wait
[13:51] <lkthomas> I see, so I2C have built-in method to tell device to wait ?
[13:52] <Amadiro> lkthomas, something like that. The master sends a packet that contains the target address of the device he wants to communicate with, as well as a "read" or "write" flag
[13:52] <Amadiro> then the master sends a "start" signal
[13:52] <Amadiro> then the master can talk to the device that has the target address the master specified
[13:52] <lkthomas> I see
[13:52] <Amadiro> and if its in write-mode, the device can send things to the master
[13:52] <Amadiro> then the master sends a stop signal
[13:52] <Amadiro> then the master can activate the next device and talk to it
[13:53] <lkthomas> token ring, LOL
[13:53] <Jck_true> Amadiro: By sending a stop signal and a new start + address
[13:53] <Amadiro> right
[13:53] <Amadiro> lkthomas, there's no ring involved
[13:53] <lkthomas> ok, understand now
[13:53] <Amadiro> http://www.totalphase.com/image/articles/i2c-diagram.png
[13:53] <lkthomas> another question, why people choose RPi instead of arduino ?
[13:54] <Amadiro> lkthomas, the arduino is a microcontroller, the rpi is more like a tiny computer.
[13:54] <lkthomas> I had a walk in downtown shops an hour ago, seems a lot of people selling it
[13:54] <Amadiro> it's vastly faster than the arduino, for instance
[13:54] <lkthomas> OH
[13:54] <lkthomas> but Arduino could run linux right ?
[13:54] <Amadiro> but the arduino in turn can do some things the rpi can't
[13:54] <Amadiro> no

[13:55] <lkthomas> what could arduino do but Rpi can't ?
[13:55] <Jck_true> lkthomas: Task scheduling
[13:55] <lkthomas> huh?!
[13:55] <lkthomas> cronjob
[13:55] <Amadiro> lkthomas, it is 5V tolerant on the pins, for instance
[13:56] <Jck_true> lkthomas: Say you want to put power on a pin the second an input is triggered
[13:56] <gordonDrogon> arduino can run linux yes. very very very slowly.
[13:56] <Jck_true> lkthomas: On linux you run intro trouble with the scheduler, you never fully know when things will happen
[13:56] <Amadiro> lkthomas, cronjobs aren't good enough if you need to respond to a signal with a fixed latency of 20 microseconds exactly
[13:56] <Amadiro> gordonDrogon, maybe the due...
[13:57] <lkthomas> really?
[13:57] <lkthomas> hmm
[13:57] <gordonDrogon> Amadiro, I think it was an Uno - I'd need to check.
[13:57] <Amadiro> gordonDrogon, I don't think the uno has either a MMU or an MPU, so I don't see how you could run linux on there meaningfully...
[13:57] <lkthomas> I am a linux engineer, I could ride on linux but not C
[13:57] <Ryanteck> 0.o
[13:58] <Ryanteck> I have no clue compared to you guys
[13:58] <Amadiro> lkthomas, if you do timing-critical tasks, having an operating system is often out-of-question in general, because it introduces too much unpredictability in terms of latency
[13:58] <gordonDrogon> it's a atmega1284p http://dmitry.gr/index.php?p=./04.Thoughts/07.%20Linux%20on%208bit
[13:58] <Amadiro> although so-called "RTOS" (real-time operating systems) exist
[13:58] <lkthomas> hmm
[13:58] <gordonDrogon> I have a little real-time task scheduller for the atmega/arduino.
[13:59] <gordonDrogon> Linux on the Pi is good enough for most tasks that don't require "hard" real-time control.

[13:59] * tektsu (~Adium@wsip-174-79-34-244.ph.ph.cox.net) has joined #raspberrypi
[13:59] <lkthomas> WoW!
[13:59] <lkthomas> good catch
[13:59] <Amadiro> lkthomas, any sort of application where you need to react to quickly changing input
[13:59] <Jck_true> lkthomas: if you call a sleep(1s) in your app you can't count on execution to continue at 1s. you know it's gonna be ATLEAST 1sec - It could be 1.0000 sec or 1.1 sec
[13:59] <lkthomas> that's true
[13:59] <Amadiro> for instance having the control surfaces on your plane react to the pilots input
[14:00] <Amadiro> or the servos responding to the wheel input in your car
[14:00] <Ryanteck> Not sure if this is possible but what about just running the basic linux kernel on the pi?
[14:00] <lkthomas> Amadiro: that will be running on FPGA?
[14:00] <FR^2> How about rt linux on a raspi?
[14:00] <Ryanteck> I guess it would be lots faster than raspbian
[14:00] <Amadiro> lkthomas, no, microcontrollers mostly
[14:00] <gordonDrogon> I think there is a port (in progress?) of RT Linux for the Pi.
[14:00] <gordonDrogon> Ryanteck, it would generally be slower, but more controllable than standard linux.
[14:00] <lkthomas> what does RT linux do? more precise timing ?
[14:00] <Amadiro> the chip in the raspberry pi is inherently limited in terms of latency & response time compared to an arduino
[14:00] <Amadiro> even if you do not factor in the OS, reaction times are unpredictable
[14:01] <gordonDrogon> Amadiro, actually, it's not the chip - it's what lies under it.
[14:01] <Amadiro> gordonDrogon, what?
[14:01] <gordonDrogon> the Pi is more than capable of hard real-time control if you take Linux away.
[14:01] <Amadiro> gordonDrogon, the videocore can acquire an exclusive lock on the bus at any time
[14:01] <gordonDrogon> although there is one final stumbling block and that's the dynamic RAM controller & GPU.
[14:02] <Amadiro> so you can't just do instruction counting like on an 8-bit AVR chip, for instance
[14:02] <gordonDrogon> no, but you have timers for that.
[14:02] <Amadiro> well, sometimes even timers aren't good enough
[14:02] <lkthomas> I throught microcontroller is gone after CPU being introduce, but I am wrong
[14:02] <Jck_true> A microcontroller is a CPU
[14:02] <Amadiro> lkthomas, they are most certainly not gone, you probably have at least half a dozen inside your computer right now
[14:03] <lkthomas> hmm
[14:03] <Amadiro> on the mainboard, in your harddisks, et cetera
[14:03] <gordonDrogon> the Pi under Linux is fine for most control stuff - just don't expect the same absolute control over it that you get with a dedicated controller.
[14:03] <Amadiro> however SoCs are displacing the high-end MCUs to some degree
[14:04] <lkthomas> gordonDrogon: can't you wrap another microcontroller on top of RPi ?
[14:04] <gordonDrogon> lkthomas, yes, and what's what I've done in the past (and am doing now)
[14:04] <Jck_true> lkthomas: Easily - Let your arduino run the time crtical stuff and fetch the dater over I2C, Uart, SPI or whatever
[14:04] <gordonDrogon> so I get an ATmega to handle some critical things like stepper motor control and just send it high-level commands from the Pi.
[14:04] <Amadiro> gordonDrogon, looks to me like the ATmega1284P also has no MMU or MPU, so you wouldn't be able to actually separate your processes
[14:04] <lkthomas> gordonDrogon: nice
[14:04] <gordonDrogon> Amadiro, read the article - it's an emulator.
[14:05] <Amadiro> uh, well, okay
[14:05] <Jck_true> Amadiro: Can you even draw the line between what is a SoC and what is a MCU?
[14:06] <Amadiro> Jck_true, its getting a little blurry, I guess -- especially since ARM is overtaking both the SoC and MCU market at a fairly rapid rate
[14:06] <Amadiro> the cortex-M0 is their most popular model yet, I think, and PICs have been in steady decline for a while
[14:07] <Jck_true> Amadiro: I've touched PIC a little - They aint developing much - Same goes for the H8 we use in a few products
[14:07] <Amadiro> but I would personally draw the line at something like "if it has an MMU, it's an SoC"
[14:07] <rdji> \help
[14:07] <lkthomas> does arduino ever hang ?
[14:07] <Jck_true> I'm actually coding for a TI chip based on Intel 8051
[14:07] <lkthomas> or does it have hardware watchdog in place ?
[14:07] <Amadiro> lkthomas, you can program it to hang, yes
[14:07] <Jck_true> lkthomas: Depends on your code
[14:07] <Amadiro> lkthomas, it has a hardware watchdog, yes
[14:08] * rdji (~rdji@110-174-160-242.static.tpgi.com.au) has left #raspberrypi
[14:08] <Amadiro> but you can disable it or hang in a busy-loop polling the watchdog
[14:08] <lkthomas> Amadiro: OH, hmm
[14:08] <Amadiro> so a watchdog is no guarantee that your program won't "hang"
[14:08] <lkthomas> then how could it be sure everything execute properly ?
[14:08] <Amadiro> as programmers always do
[14:08] <Amadiro> they test their code
[14:09] <Jck_true> Amadiro: You had a problem so you add a watchdog - Now you have an extra problem which covers the old one...
[14:09] <lkthomas> ok, put it this way, if whenever things happen on a Jet microcontroller which cause it hang, how does it recover ?

[14:10] <lkthomas> Jck_true: what if memory error...etc ?
[14:10] <Amadiro> for one project I did a while back we needed to put a watchdog on a PC, to reboot it when it hung, so I put a pic chip on it.. then enabled the watchdog on that pic-chip... and then put a hardware watchdog made from a 555 and some caps on there that would reset the pic chip as well
[14:10] <lkthomas> it's not ASIC, how does it be sure, I don't understand
[14:10] <Amadiro> I was slightly more paranoid back then than I am now
[14:11] <Jck_true> lkthomas: Memory error? Myth
[14:11] <lkthomas> Amadiro: hardware watchdog for PC is very expensive
[14:11] <Amadiro> lkthomas, 25$ or so
[14:11] <lkthomas> Jck_true: huh? it will cause error for sure
[14:11] <lkthomas> Amadiro: err
[14:12] <lkthomas> my friend ask me to work on something like hardware ticket system which you press a button and new number print out
[14:12] <lkthomas> I think RPi could fit the work
[14:12] <Amadiro> yes, the rpi would probably work for that
[14:12] <Amadiro> you can find those ticket printers on ebay for not too-much money, and they usually come with usb or a serial port
[14:12] <lkthomas> does arduino have a DB structure ?
[14:12] <Amadiro> so you can connect them to the pi fairly easily
[14:13] <Amadiro> lkthomas, its programmable, you can program it to have a "db structure" if you want to
[14:13] <lkthomas> Amadiro: call sqlite library maybe ?
[14:13] <Amadiro> no, sqlite wouldn't run ot it
[14:13] <lkthomas> LOL
[14:13] <Amadiro> sqlite requires you to have an operating system & file-system working
[14:13] <lkthomas> a ticketing system require some DB to count on ticket number
[14:14] <Amadiro> but you can make your own little database-library that reads/writes to the EEPROM that you have in most AVR chips
[14:14] <Amadiro> you usually get something like 1 to 2 kilobytes

[14:14] <Jck_true> Amadiro: Actually - They have been kind on SQLite - The file functions are defines() so you *could* implement it
[14:14] <lkthomas> ha, too much work
[14:14] <lkthomas> no wait, back the RPi, when someone press a button, what program could you use to trigger an event ?
[14:15] <Amadiro> lkthomas, its not that much more work compared to doing an app on the rpi that uses sqlite, but using the pi is certainly more flexible, since you can add, say, a webinterface.
[14:15] <Amadiro> lkthomas, that depends on how you want to connect the button to the rpi
[14:15] <Amadiro> you could have it poll a GPIO pin, for instance
[14:15] <lkthomas> isn't GPIO ?
[14:15] <Amadiro> isn't GPIO what?
[14:15] <lkthomas> connect a button with GPIO, when a button press, signal generate to RPi
[14:16] <gordonDrogon> yes, you can do that.
[14:16] <Amadiro> yes, that would work.
[14:16] <lkthomas> then what program can I use to trigger
[14:16] * Megaf (~PhenomIIx@unaffiliated/megaf) Quit (Quit: Leaving)
[14:16] <Amadiro> lkthomas, gordonDrogon wrote a library called "wiringPi", you can use that to poll the GPIO pins.
[14:16] <lkthomas> press a button would take less than 0.5 second
[14:17] <lkthomas> how quick could the polling do their job ?
[14:17] <Amadiro> there are also python libraries and such
[14:17] <Amadiro> lkthomas, a few times per second would probably be fine, but if you are concerned about missing a keypress, you can extend the buttons signal with a 555 timer or so
[14:17] <gordonDrogon> you can also send interrupts to a program so you don't need to actively poll.
[14:18] * Ryanteck (~Ryan@fsf/member/Ryanteck) Quit (Quit: Leaving.)
[14:18] <lkthomas> gordonDrogon: what program could use to monitor interrupts then ?
[14:18] <gordonDrogon> and the gpio has edge detection, so you never need to miss the briefest of touches.
[14:18] <lkthomas> I am an engineer, want to make things simple without programming :)
[14:18] <gordonDrogon> lkthomas, you write one - to use a library I wrote called wiringPi.
[14:19] <lkthomas> example page is 404 not found my dear friend
[14:19] <gordonDrogon> lkthomas, you can not NOT program. At some point you need to write something - a script, something and that's a program.
[14:19] <gordonDrogon> what example page?
[14:19] <lkthomas> bash script, so yes
[14:19] <lkthomas> https://projects.drogon.net/raspberry-pi/wiringpi/

[14:28] <Jck_true> Amadiro: That's what I can't tell completely :)
[14:29] <Amadiro> looks to me like the external input goes from -0.5 to 0.3 (low) to 0.7 to 5.5 (high) too

[14:29] <lkthomas> Amadiro: hmm
[14:29] <Amadiro> but that thing is really weak anyway
[14:29] <Amadiro> what do you want with 50mA
[14:29] <lkthomas> Amadiro: should I write a bash loop to monitor button pressing ?
[14:30] <Jck_true> Amadiro: That board would just simplify wiring a bit for a project I have in mind
[14:30] <neilr> hi all - sorry, just catching up with this conversation. lkthomas: are you restricted to linux as an operating system?
[14:30] <lkthomas> neilr: I am
[14:30] <Amadiro> Jck_true, I'd just go with a 2$-solution and get some microcontroller like an AVR and program that, more versatile
[14:30] <Amadiro> Jck_true, or perhaps even get a teensy for 12$ or so, then you can connect it via USB
[14:30] <neilr> Ah, OK - just that I have some BASIC code that runs on RISC OS and monitors button presses on the GPIO pins
[14:30] <Amadiro> or use a beefier chip for heavier loads
[14:31] <Amadiro> the teensy (or any other AVR chip) will also have more lines than this one

[14:31] <lkthomas> Amadiro: write loop ?
[14:31] <Amadiro> lkthomas, yes
[14:32] <Amadiro> Jck_true, what's a PLC
[14:32] <Jck_true> Amadiro: Programmable Logic Controller...
[14:32] <Jck_true> Amadiro: Sort of like "hook a float sensor to input one and a water pump to output 2"
[14:32] <lkthomas> Amadiro: do you think the loop will miss any event ?! this part I am not sure
[14:33] <Amadiro> lkthomas, as I said earlier, you can extend the signal with a 555 timer, if you're most comfortable with the hardware-side, or use proper interrupts, if you're more comfortable with the software-side
[14:33] <lkthomas> neilr: RISC OS 6 is not open source
[14:33] <Amadiro> Jck_true, sounds like a microcontroller is definitely the better choice, since you also get things like ADCs and PWM pins
[14:34] <lkthomas> OH, 555 timer is an object
[14:34] <lkthomas> please clarify what is "proper interrupts"
[14:34] <Amadiro> lkthomas, attaching a handler to an interrupt on an interrupt-able pin
[14:34] <Jck_true> Amadiro: Suppose so - I guess I just love I2C too much :)
[14:34] <Amadiro> then that interrupt will get fired when the pin changes state
[14:35] <Amadiro> Jck_true, you can connect the MCU using I2C, no problem
[14:35] <lkthomas> Amadiro: any example and program I could use on bash to handle interrupts ?
[14:36] <Amadiro> I kinda doubt you can do that with bash, you might need to use python for that
[14:37] <Amadiro> in python it's something like "set_rising_event(11)" and then you can use "GPIO.event_detected(11)"

[14:39] <Amadiro> maybe, ask gordonDrogon
[14:39] <Amadiro> but I'd just use python or so
[14:39] <lkthomas> heh, ok

[14:54] <Amadiro> no
[14:54] <Amadiro> the rpi has a CSI connector onboard for camera connections, but I don't know what the status on that is, i.e. whether it is currently usable

[14:55] <neilr> I use one to display temperatures, time, IP address and something else I've completely forgotten about now

[15:14] <Amadiro> _julian, interesting, thanks.
[15:14] <_julian> Amadiro: actually I plan to draw the video with gles (gstreamer), but as I have some issues there (image is only painted as solid color instead of the actual texture) I wanted to make up some minimal test case
[15:14] <Amadiro> _julian, does gstreamer have an OpenMAX backend?
[15:15] <_julian> Amadiro: yes, omx is working. I lately added mpeg2 support to it (http://cgit.freedesktop.org/gstreamer/gst-omx)
[15:15] <Amadiro> cool
[15:15] <_julian> what's currently missing is a proper video output plugin. my plan is to use egl/gles
[15:16] <Amadiro> _julian, unfortunately we can still not get an accelerated window under X
[15:16] <_julian> I already have a patch for eglglessink that makes the window setup and stuff, but it only draws one solid color (the color placed at the texture pixel which collates to the vertex -1, -1)

[15:23] <lkthomas> so GPIO is a serial bus, does it means one pin connect two module at the same time ?
[15:23] <Amadiro> lkthomas, GPIO is not a serial bus, GPIO just means you can set the pins in software however you want
[15:23] * int3nz0r (~int3nz0r@ip5455f582.speed.planet.nl) Quit (Ping timeout: 252 seconds)
[15:23] <Amadiro> so you can use it to implement a parallel bus, or a (slow) serial bus
[15:24] <lkthomas> Amadiro: so how does it work if I want to run LCD display as well as DHT22 sensor ?
[15:24] <Jck_true> lkthomas: You use differnt ports
[15:24] <lkthomas> what "ports" are you talking about
[15:24] <Amadiro> lkthomas, if they are both I2C, you just connect them both in parallel to your I2C pins, for instance
[15:24] <Amadiro> if one uses SPI, the other I2C, you connect them to each their appropriate pins
[15:24] <Amadiro> etc
[15:25] <lkthomas> I am not sure what does it run on
[15:25] <Jck_true> In the case of DHT11 you have to bit bang on the GPIO io pins
[15:25] <lkthomas> sorry, newbie :P
[15:25] <Amadiro> read the datasheet
[15:25] <Amadiro> it'll tell you what interfaces it supports
[15:25] <lkthomas> Jck_true: what do you mean
[15:25] <lkthomas> Amadiro: right, will check it
[15:25] <Jck_true> lkthomas: Check the forums for DHT11/22 plenty of guides setting that up
[15:26] <Jck_true> As to LCD displays it depends on the type -
[15:26] <lkthomas> Jck_true: I have it on hand, but none of them connect two or more devices at the same time
[15:26] * int3nz0r (~int3nz0r@ip5455f582.speed.planet.nl) has joined #raspberrypi

[15:27] <Jck_true> (And make sure they are 3V3 compatible)

[15:27] * neilr (~neilr@ has joined #raspberrypi
[15:27] <_julian> linuxstb: using the omx video_render component does not fit into the gstreamer module concept. you would have to distribute the omx tunnel between the video decoder and video sink plugin, which is hardly possible

[15:28] <lkthomas> "digital signal via single-bus" ?
[15:28] <_julian> linuxstb: but it is possible to head over an EGLImage (which can be created by OMX) to the eglglessink
[15:28] <_julian> which should achieve a good performance as well

[15:29] <Jck_true> lkthomas: " Many low cost sensors have unusual output formats, and in this case, a "Manchester-esque" output that is not SPI, I2C or 1-Wire compatible"
[15:30] <lkthomas> Jck_true: so what if I want to connect other devices, how should I do
[15:30] <_julian> although right now I am working on step 1, which means doing a CPU memory copy. but as soon as this works I will try to get EGLImage rendering set up
[15:30] <lkthomas> Jck_true: connect as parallel ?
[15:30] <linuxstb> _julian: OK, nice. So basically the GPU renders into a GPU buffer, you can then manipulate that buffer, and then you tell the GPU to display it?
[15:30] <_julian> linuxstb: yes
[15:30] <Jck_true> lkthomas: Depends on the type of device - In this case it's not a bus - So you need a new pin for each sensor
[15:31] <lkthomas> Jck_true: make sense, what if LCD display want to use the pin which DHT22 already using ?

[15:31] <Jck_true> lkthomas: You move it to another pin
[15:32] <Jck_true> (if you can)
[15:32] <lkthomas> really?
[15:32] * rolleiflex (~rolleifle@ has joined #raspberrypi
[15:33] <Amadiro> lkthomas, here's the basic rundown: on the pin-header, you can connect 1 serial (rs232) device to your pi, 127 (or-so) I2C devices, 4000-or-so SPI devices (in theory), but each SPI device will usually in addition to being connected to your SPI bus require you to use up one GPIO pin; then the rest of the GPIO pins you can use to connect whatever kind of things, but only talk to the devices very slowly.
[15:35] <lkthomas> Amadiro: second part I don't understand, each SPI device will use one GPIO pin ?
[15:35] <Amadiro> yes. so if you have 3 SPI devices connected, you'll need 3 pins for the SPI bus + 3 select pins, one for each device.
[15:36] <Jck_true> lkthomas: Chip select pin - You need to be able flipping a switch that decides which device you're talking to
[15:36] <lkthomas> so if all 26pins being use, no more SPI device could be add
[15:36] <Amadiro> I2C encodes this "slave select" into the protocol, which makes it much uglier from a data implementation point-of-view, SPI uses a simple on/off wire to select the slave, which makes it uglier from a wiring-point-of-view
[15:36] <Jck_true> lkthomas: You can't reach 26 - Not all pins are controlable
[15:37] <pronto> http://www.amazon.com/Transcend-Class-Flash-Memory-TS8GSDHC10E/dp/B003VNKNEG/ wow, these are stupid cheap :| 8gb class 10 $8
[15:37] <lkthomas> err
[15:38] <Jck_true> lkthomas: must be ~10-12 SPI devices tops
[15:38] <Amadiro> lkthomas, http://elinux.org/RPi_Low-level_peripherals look at the image
[15:38] <Amadiro> only those that say "GPIO" you can control manually
[15:38] <Amadiro> the ones that have something in parens, you cannot control if you want to use the functionality in the parens
[15:38] <Amadiro> so for instance if you want to use SPI, you cannot use GPIO pin 10, 9 and 11
[15:39] <Amadiro> because MOSI, MISO and SCLK are used for SPI
[15:39] <Amadiro> plus one additional one that you can chose yourself
[15:39] <Amadiro> for each device
[15:39] <Amadiro> if you want to use the rs232 line, OTOH, you have to give up GPIO pin 14 and 15
[15:40] <lkthomas> where did you find out pin 10, 9, 11 can't be use ?
[15:40] <Amadiro> (TXD and RXD)
[15:40] <Amadiro> it says so in the parens
[15:40] <Jck_true> lkthomas: They are labled in purple
[15:40] <Amadiro> "GPIO 10 (MOSI)"
[15:40] <Amadiro> that means you can either use it as GPIO, or for MOSI
[15:41] <Amadiro> MOSI is required for SPI, so you can either use SPI, or the GPIO pins
[15:41] <Amadiro> (MOSI is one of the data-lines for SPI that sends data from the rpi to the device you're talking to)
[15:41] <Amadiro> (It sands for "Master Out, Slave In")
[15:42] <lkthomas> so all devices jam into MOSI, MISO and SCLK in parallel form ?
[15:42] <Jck_true> lkthomas: Correct
[15:42] <Amadiro> lkthomas, yes, plus one activation line for each device, as I said
[15:42] <Jck_true> lkthomas: And you choose which one to talk with from a sperate pin
[15:42] <lkthomas> now I start to understand
[15:42] <Amadiro> lkthomas, with I2C, all the devices are connected to GPIO 0 (SDA) and GPIO 1 (SCL) -- no further lines are required, regardless how many devices you have
[15:42] <lkthomas> BUT, for DHT22, is it using RS232 ?
[15:43] * dero (~dero@ Quit (Quit: Leaving.)
[15:43] <Jck_true> lkthomas: DHT22 aint using either standard
[15:43] <Amadiro> just don't use the DHT22, mhkay
[15:43] <Jck_true> It has to be manually "hacked"
[15:43] <lkthomas> Jck_true: so what is the standard that it is using ?!
[15:43] <Amadiro> use something that uses I2C, it'll be the easiest
[15:43] <Jck_true> Read the datasheet on that
[15:44] <lkthomas> Amadiro: does it means if it's not using standard, it will screw up the standards which use those pins ?
[15:44] <Jck_true> lkthomas: Not at all
[15:44] <Amadiro> lkthomas, if it doesn't talk SPI, I2C or rs232 (serial) it means you simply cannot connect it to those pins and get it to work
[15:44] <Amadiro> so instead, you have to turn the pins on and off really fast manually to implement the protocol the device wants to talk
[15:44] <Amadiro> which is very slow and unreliable
[15:44] <Jck_true> lkthomas: Picture it as differnt languages - SPI is one language, UART a differnt, I2C a 3rd
[15:45] <lkthomas> Jck_true: I understand, but after look into DHT22, I can't tell which protocol does it talking with RPi
[15:45] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 246 seconds)
[15:45] <Amadiro> lkthomas, it uses a proprietary protocol called one-wire
[15:46] <Amadiro> you can get adapters for it that convert it to SPI
[15:46] <Amadiro> but the pi doesn't support the protocol natively
[15:46] <Jck_true> lkthomas: I'll repost what I qouted earlier " Many low cost sensors have unusual output formats, and in this case, a "Manchester-esque" output that is not SPI, I2C or 1-Wire compatible must be polled continuously by the Pi to decode. Luckily, the C GPIO libraries are fast enough to decode the output. "
[15:47] <Amadiro> one-wire is one of those protocols you really don't want to implement with bitbanging if you can at all avoid it, since it requires you to do frequency recyling, since it doesn't have a CLK line like SPI or I2C
[15:47] <Weaselweb> there are several USB-1-wire adapters
[15:47] <Amadiro> so if reliability means anything to you, just leave it alone or get an adapter
[15:47] <lkthomas> Jck_true: too many technical terms, does it means even it is using 1-Wire, RPi C GPIO library could decode output ?
[15:47] <Amadiro> lkthomas, yes, but you have to do it manually and it'll be super-slow and super-unreliable.
[15:48] <Amadiro> (well, I don't think 1-wire is fast in the first place, so whatever)
[15:48] <Jck_true> lkthomas: Means that the native hardware on the raspberry doesn't support the protocol it's using - So you have to implement it in software
[15:48] <Amadiro> but it'll eat up tons of your CPU resources.
[15:48] <lkthomas> ok, please define what is "Manually" ? like execute command by hand to get output ?
[15:48] <lkthomas> Amadiro: no wait, I2C and SPI is hardware accelerated protocol ?
[15:49] <Amadiro> yes
[15:49] <Amadiro> lkthomas, think of protocols like SPI and I2C like frequencies that you can talk on. your rpi can already send and receive on the SPI frequence and on the I2C frequency, but it doesn't know how to send or receive on the one-wire frequency
[15:49] * lkthomas didn't know that
[15:49] <Amadiro> so instead, you have to manually say "high! low! high! low!" really fast to "simulate" the frequency
[15:49] <Weaselweb> i wouldn't say SPI is a protocol
[15:49] <Amadiro> at just the right, well, frequency
[15:49] * Orion_ (~Orion_@ has joined #raspberrypi
[15:49] <lkthomas> Amadiro: that means, I have to becareful on checking CPU usage
[15:50] <Amadiro> and that way you still can talk to 1-wire devices, but you will be busy all the time toggling the pin, and if the OS decides to interrupt you for some reason (as operating systems tend to do) it might mess up your timing and you have to re-do the frequency
[15:50] * Sendoushi (~Musok@cm2-84-91-84-50.netvisao.pt) has joined #raspberrypi
[15:50] <Amadiro> so it can be done, but it is really icky
[15:50] <lkthomas> understand now
[15:50] <Weaselweb> bit banging is just last resort
[15:50] <Amadiro> hence why you should instead just use something with I2C, SPI or get a one-wire-to-SPI adapter
[15:50] <lkthomas> Amadiro: does it matter if I don't request sensor response often ?
[15:51] * tubadaz (~quassel@pdpc/supporter/student/tubadaz) has joined #raspberrypi
[15:51] <Amadiro> lkthomas, that'll certainly help your overall CPU usage, but it's still somewhat unreliable
[15:51] <Jck_true> lkthomas: Of course - You just request it less often
[15:51] <lkthomas> well, that's controllable
[15:51] <lkthomas> I plan to request every minute
[15:51] <lkthomas> that's not a lot
[15:51] <Amadiro> having a high CPU usage while trying to bitbang the pin may have negative side-effects, for instance
[15:51] <Amadiro> or playing a video
[15:52] <lkthomas> hmm
[15:52] <lkthomas> side effect = retry ?
[15:52] <Amadiro> probably
[15:52] <lkthomas> that's not too bad
[15:52] <Jck_true> Or lag in other application
[15:52] <lkthomas> Jck_true: it will hold up other application as an interrupt ?
[15:52] <Jck_true> (But I guess It won't take very long)
[15:53] <lkthomas> hmm
[15:53] <lkthomas> should be quickl
[15:53] <Jck_true> It's reading like 16 bits from the temp sensor - Should run smooth -
[15:53] * Orion_ (~Orion_@ Quit (Ping timeout: 252 seconds)
[15:53] <lkthomas> Jck_true: huh?! what's that
[15:54] <Jck_true> lkthomas: You know about hex/binary/bytes?
[15:54] <lkthomas> kind of, but why 16 bits will be smooth
[15:54] <Jck_true> lkthomas: It's short - Compared to transfering a frame to a 480x320px display
[15:55] <lkthomas> and ?
[15:56] <Amadiro> lkthomas, transferring less data takes less time, so less interruption for other things to happen
[15:56] <Jck_true> Less waiting for individual bits etc
[15:56] <Amadiro> lkthomas, do you own an oscilloscope
[15:56] <lkthomas> I see, no
[15:57] <Amadiro> lkthomas, before you do any of this, you're probably well-advised to get an oscilloscope and learn how to use it
[15:57] <Amadiro> lkthomas, an oscilloscope allows you to "hook" into the connection and see all the bits as they are transferred

[15:57] <_julian> http://pastebin.com/GKQXVX3k
[15:58] <Amadiro> once you run into problems (which tends to happen with bitbanging) the oscilloscope will help you figure out what's going wrong
[15:58] <_julian> this should render a 320x240 window with 10 alternating red/black vertical bars
[15:58] <Amadiro> A logic analyzer works too, but they are harder to use
[15:58] <lkthomas> Amadiro: is it getting too far ?! I am currently just trying examples which posted by someone else
[15:58] <Jck_true> lkthomas: The example in this case is I2C - But should show some of it
[15:58] <_julian> but I only get a plain red fill
[15:58] <_julian> if I change line 256, which is the texture coordinate related to vertex coordinate -1,-1 to 0.55,0.55 I get a plain black fill, because I hit a black bar then
[15:58] <lkthomas> sorry guys, way over my head now
[15:59] <Jck_true> haha you can pm me but i gotta run in 10 minutes
[15:59] <_julian> could someone try this example and see if it behaves as I see? maybe my gl system is garbled or anything like that

[16:50] <ReggieUK> SwK, it could be polyfuses (depending on the version of pi) or it could be poor quality cables or it could be the polyfuses at the usb out end of the chain
[16:50] <SwK> ReggieUK: Bv2
[16:50] <murphycr> pronto: Very clever. I wish I had thought of that 2 days ago.
[16:51] * murphycr steals the idea :P
[16:51] <pronto> murphycr: set it up with ssh keys, and make yoru tunnelacc shell = /bin/false
[16:51] <pronto> so it can make a passowrdless, no shell, tunnel
[16:52] <pronto> and, autossh is in the repo for the debain raspberry distro :D
[16:52] <nid0> what particularly do you need autossh for to do that instead of just ssh -R?
[16:53] <pronto> nid0: incause for what ever reason the tunnel goes down, it'll bring it back up
[16:53] <murphycr> Oh. Another question for you all: My USB hub leaks current back to the Pi; is it safe to power it that way?
[16:53] <nid0> murphycr: yes
[16:53] <murphycr> nid0: thanks!
[16:53] <nid0> the ability to do so is why the foundation removed the polyfuses on the usb ports
[16:54] <SwK> ReggieUK: when I dont think the cable is the problem as I measure at the micro USB input direct to where it is soldered to the PCB, then measured across the large input filter cap there and theres a .3v drop already
[16:54] <ReggieUK> which is kinda crazy because it's not supposed to leak power backwards (on a usb hub)
[16:54] <murphycr> ReggieUK: one would think.
[16:55] * Peetz0r (~peter@ has joined #raspberrypi
[16:55] <mjr> not supposed to, but hey, it's cheap
[16:55] <aldasa> @bar(input):button1
[16:55] <mjr> nid0, is that why though? I thought it was because of usb stability
[16:56] <ReggieUK> Swk, it could be because of the already high resistance in the micro usb cable, anything further up using current could make it drop

[16:56] <mjr> ie. I'm not sure how powering the Pi that way goes wrt. warranty, since it bypasses the input fuse. It does work in practice though.
[16:56] <Peetz0r> Hi, this happened after I conencted a phone (SE k550i) to the usb port: https://p.6core.net/p/709sexa3jb93hyt5
[16:56] <SwK> ReggieUK: is there really anything between the usb connector and that filter cap?
[16:56] <ReggieUK> I've got a couple of hubs here, the one that backfeeds power is a poorly made chinese one
[16:57] <mjr> nid0, okay. Well. I suppose a statement like that alleviates warranty concerns.
[16:57] <Peetz0r> and now it won't boot at all. The sd card is still fine

[17:14] <Peetz0r> the problem is on the board which doesn't have polyfuses
[17:14] <ReggieUK> :/
[17:14] <ReggieUK> eeek
[17:14] <IT_Sean> and several hours means several hours. Not 5 minutes.
[17:14] <Peetz0r> the rev2 board has the problem, the rev1 board is working fine
[17:14] <IT_Sean> oooh
[17:15] <IT_Sean> you might have nuked it.
[17:15] <nid0> since when does a phone backfeed power?
[17:15] <ReggieUK> it doesn't have to
[17:15] <Peetz0r> (I haven't yet tried plugging in my phone in the rev1 board after this)
[17:15] <nid0> why not, the pi's power input still has a polyfuse
[17:15] <IT_Sean> It may not have been a backfeed issue.
[17:15] <Peetz0r> nid0: true
[17:15] <ReggieUK> aha
[17:16] <nid0> you're only going to nuke a pi either by backfeeding, gpio, or shorting the input fuse
[17:16] <Peetz0r> the Pi still responded after plugging in the phone
[17:16] <Peetz0r> see tha 2nd half of the terminal output
[17:16] <Peetz0r> the*
[17:16] <nid0> Peetz0r: have you tried 1) that SD in another pi and 2) a fresh sd image in that pi
[17:16] <nid0> because your log suggests you've got a nackered (wiped) os on that card
[17:17] <Peetz0r> nid0: yes, as I said, the same cars still works on another Pi and in my laptop

[17:34] <parabyte> i got a interesting use for the pi as its so cheap
[17:35] <parabyte> :D
[17:35] <parabyte> can the pi act as a usb host?
[17:36] <Peetz0r> parabyte: definately
[17:36] <Peetz0r> it has two regular usb ports :)
[17:36] <parabyte> hang on my terminology is confused
[17:36] <IT_Sean> parabyte: that's what the two USB ports onnit are for.
[17:36] <parabyte> i meant as usb client
[17:36] <parabyte> !!
[17:36] <IT_Sean> oh... No.
[17:36] <IT_Sean> It's a computer, basically.
[17:36] <parabyte> if i plug it say into a pc it comes up as a usb device
[17:36] <parabyte> yeah i know
[17:36] <IT_Sean> So, it acts as a USB host.
[17:36] <parabyte> i wanna use it as a embedded controller
[17:36] <IT_Sean> Not as a client.
[17:36] <parabyte> that plugs into my pc as a client
[17:36] <parabyte> :D
[17:36] <parabyte> lol
[17:36] <IT_Sean> That won't work, sorry.
[17:37] <Peetz0r> parabyte: can you use a network conenction for what you want?
[17:37] <parabyte> maybe its got enough guts to run mixxx dj software
[17:37] <Peetz0r> or maybe a serial conenction?

[17:40] * Welington (~carlos@mvx-200-196-57-166.mundivox.com) has joined #raspberrypi
[17:40] <IT_Sean> parabyte. It is a computer. Not a client device.
[17:40] <IT_Sean> It is meant to have other things attached to it.
[17:40] <IT_Sean> You can't do both.
[17:40] <Peetz0r> murphycr: yeah, might be a good option
[17:41] <parabyte> no hacks to put it into client mode?
[17:41] <IT_Sean> No.
[17:41] <IT_Sean> It is not physically capable, at all, of working as a USB client.
[17:41] <murphycr> well, you _could_ use a usb-to-serial adapter and connect to the serial pins on the GPIO header
[17:41] <murphycr> Then you'd have a console, but that's about it
[17:42] <IT_Sean> You could. It would be slightly hairy, however.
[17:42] <Peetz0r> I actually do ahve a powered usb hub. Now I need to find a way to power the Pi and the phone trough that hub from a portable power source
[17:42] * pretty_function (~sigBART@ has joined #raspberrypi
[17:42] <IT_Sean> And it would give you a terminal.
[17:42] <Peetz0r> maybe an old laptop battery. does anyone have experience with powering a Pi from a battery?
[17:42] <parabyte> Peetz0r, just basic electronics
[17:42] <Peetz0r> actually, I need to power the Pi, phone, webcam and 2 knex motors from a battery :D
[17:43] <murphycr> Peetz0r: the trick there is charging it... I'd recommend just getting a dedicated LiPo battery
[17:43] <IT_Sean> you'll need a decent battery
[17:43] <parabyte> iv powered armel based access points for years off random batteries and solar cells
[17:43] <Peetz0r> I'll need to find out how much power all those devices use together
[17:43] <Peetz0r> also, I need to find a way to safely connect those motors to gpio in the first place
[17:44] <Peetz0r> enough work to do :D
[17:44] <IT_Sean> you will need a motor controller
[17:44] * Gordio (~Gordio@ Quit (Remote host closed the connection)
[17:44] <IT_Sean> connecting them directly to the GPIO is generally A Bad Idea, as they aren't designed to directly run any motor beefy enough to move that lot.

[17:44] <Peetz0r> yeah, I've seen that before
[17:45] <Peetz0r> I'd like to know hoe bad it is to power those 3v motors using 5v. would it do faster, or would it go poof? :p

[19:18] <IT_Sean> There you go.
[19:18] <Aebleskiver> Do you just run your boot partition on the SD and then have your rootfs on something else like a hard disk?
[19:19] <Aebleskiver> Was wondering if it would be better to do that because of the flash wear...

[19:25] <IT_Sean> Wot 'e said
[19:25] <Aebleskiver> hehe
[19:25] <IT_Sean> Besides... SD cards are cheap. Just keep occasional backups, and when it goes bad (in a few years) replace it.
[19:25] <Aebleskiver> Ahh well, I guess as long as I do regular backups it won't matter
[19:25] <Aebleskiver> Yep
[19:26] <Aebleskiver> Sounds good...
[19:26] <Torikun> you all will have new Pi's before the SD goes bad
[19:26] <Torikun> face reality here =)
[19:26] <IT_Sean> wha's an SD card cost these days anyway? :p
[19:26] <Aebleskiver> probably will be able to buy a 32GB one for ??0.05 in a few years anyhow
[19:26] <Torikun> IT_Sean: I got some on amazon 8GB for like $2
[19:26] <pronto> Torikun: where?
[19:26] <Torikun> amazon.com
[19:26] <pronto> like, link
[19:26] <IT_Sean> he just said... Amazon.
[19:26] <Torikun> lol
[19:26] <pronto> like, do you have the link to the page :/
[19:27] <Torikun> Go Amazon lol
[19:27] <Aebleskiver> one great thing about the Pi is that it ignores the write protect tab on the SD :)
[19:27] <Torikun> I got one fore 49 cents here

[19:27] <Aebleskiver> useful because my SD for it lost it a while back
[19:28] <dape> i don't think card bigger than 8 gb justify their purchase for a Pi, maybe a 16 gb if you run multiple desktop environments and such graphical stuff but for something like Arch Linux mini server a 8 gb its more than enough
[19:28] <Xeph> hey, i got a B model with archlinux installed. xbmc wont show any video playback, while omxplayer does. any hints, any ideas? recent firmware, recent software
[19:28] <Aebleskiver> I have some really cheap Chinese class 10 32GB SD for it, it was only ??15
[19:28] <Aebleskiver> it's disintegrating around the circuit board though
[19:28] <Torikun> how you get xmbc installed on arch ? I can't get it to compile
[19:28] <Aebleskiver> using superglue and tape to hold it together now :)
[19:28] <pronto> Torikun: is class 4 okay for booting off of?

[19:29] <Torikun> even my old 256MB SD works fine
[19:29] <Aebleskiver> So I don't have to remove it from the slot too much :D
[19:29] <Torikun> Xeph: I hope your not using ext4 on arch
[19:29] <Torikun> lol
[19:29] <Aebleskiver> Torikun: Try posting the compile errors and maybe someone will tell...
[19:29] <dape> why not ?

[19:32] <Torikun> lol ok
[19:33] <Aebleskiver> I think one small thing was that it can't play any video that has an ac3 stream
[19:33] <Torikun> oh
[19:33] <Aebleskiver> it doesn't have a hardware decoder for it..
[19:33] <Torikun> so basicall OMX player does not ?
[19:33] <Aebleskiver> H.264/AAC is fine I think
[19:34] <Aebleskiver> Yep, think so
[19:34] <Torikun> ah ok
[19:34] <Xeph> Aebleskiver: Is there anything that I might forgot during setup? xbmc plays my matroskas, but without video :)
[19:34] <Aebleskiver> like the screen just goes blank?
[19:36] <Aebleskiver> does it play any video at all, or just the mkv has a problem?
[19:36] <Viper-7> Torikun: it can pass AC3 raw out of hdmi, it just cant decode it to analog onboard
[19:36] <Viper-7> also http://www.raspberrypi.com/mpeg-2-license-key/
[19:36] <Xeph> nope, xbmc gui still visible. in fullscreen, of course it's blank :) when I hit "O", it shows the audio stream ( D(Audio???), but video: D() P(fr:23.976,vq0%,dc::,Mb/s:0.00)
[19:36] <Torikun> ah
[19:36] <Aebleskiver> Viper: Ahh, I see

[21:21] <Aebleskiver> i.e. they can make large quantities of the model B cheaper than maintaining production of two models, one of which I don't see being very popular
[21:21] <Amadiro> it does seem somewhat useless without the networking...
[21:22] <Aebleskiver> Sorry, I welcome other opinions of course, that's just what I've been thinking :)
[21:22] <Joeboy> model A is just model B with some bits missing, I think. Not a huge overhead to manufacturing both models
[21:22] * Sendoushi (~Musok@cm2-84-91-84-50.netvisao.pt) Quit (Remote host closed the connection)
[21:22] <Joeboy> although that begs the question as to why they haven't managed to make any yet
[21:22] <Squirm> I wouldn't like network missing. but there should still be usb. means for wireless
[21:23] <Aebleskiver> Only one USB though?
[21:23] <IT_Sean> yes
[21:23] <pksato> Remember primary use for Raspberry Pi.
[21:23] <Squirm> powered hub?
[21:23] <IT_Sean> you can still use a powered hub with it, of course
[21:23] <Aebleskiver> So you'd actually need to outlay more for the model A in a sense, having to purchase a powered hub
[21:23] <rymate1234> education
[21:24] <IT_Sean> You need a powered hub with the B anyway, in most cases
[21:24] <IT_Sean> And besides... the A is not designed for the dev community... it's designed for education.
[21:24] <rymate1234> with the model A
[21:24] <rymate1234> you could use it as a headless server
[21:24] <Amadiro> Aebleskiver, even two usb ports is so little, however, that you'll likely have to get a hub anyway
[21:24] <Squirm> I think both are designed for education either way. B will just be more all-round
[21:24] <rymate1234> just stick a wifi dongle into the usb port
[21:24] <Amadiro> at least for most applications
[21:24] <Joeboy> I think there must be uses for a tiny, low power, disposably cheap machine with one USB port.
[21:24] <Armand> I'd rather drop both USB ports, than LAN. :P
[21:25] <Amadiro> I haven't seen many people use a model b without hub, yet

[21:31] <ReggieUK> afaik yeah
[21:31] <pksato> mdik: Yes, same complaint about the model B. They forget that the RPI are for education.
[21:32] <Squirm> murphycr: but it will have wifi, gps, etc.
[21:32] <Squirm> ReggieUK: ok. don't have the money for the bits yet anyway. so I can wait

[21:38] <pronto> i'm a horrible and disquesting person... to get wvdial dial to start on boot... i just tossed "wvdial &" in the init.d script for sshd start) case
[21:38] <mdik> but i'm in my third bottle of beer this evening and seems to occur to me that the damage one bike-accident earlier today left may be more significant than i thought... good night

[21:39] <pronto> but i'm lazy xD
[21:40] <pronto> but now on boot, it starts it, and with a cronjob running autossh , it creates a remote tunnel to my vps for ssh :D

[23:28] <b03tz> Hi y'all :) I've got a MCP3008 question
[23:28] <b03tz> Anyone can help?
[23:29] <gordonDrogon> A/D converter?
[23:29] <b03tz> Yes
[23:30] <b03tz> I doesn't seem to matter which resistor I hook up to the channel 0
[23:30] <b03tz> I always reads max voltage...
[23:30] <b03tz> When disconnected, it reads 0
[23:30] <gordonDrogon> that's probably right.
[23:31] <gordonDrogon> you need 2 resistors in a divider.
[23:31] <b03tz> What?
[23:31] <gordonDrogon> you need 2 resistors in a divider.
[23:31] <b03tz> Ah thanks
[23:31] <b03tz> What?
[23:31] <b03tz> :D
[23:31] <b03tz> A divider...
[23:31] <b03tz> I think I know what you mean
[23:31] <b03tz> Hold on ;)
[23:31] <gordonDrogon> if you connect just one to +ve then that will read max.
[23:31] * bortzmeyer (~stephane@2a01:e35:8bd9:8bb0:5c7e:a341:65eb:eb9e) Quit (Quit: Leaving.)
[23:31] <b03tz> Because the resistors limits the current flow not the voltage
[23:31] <b03tz> ?
[23:32] <gordonDrogon> so wire 2 resistors in series between +ve and 0v and connect the mid-point to the input.
[23:32] <gordonDrogon> yes, it's current limiting.
[23:34] <b03tz> Got it...
[23:34] <b03tz> Awesome :)
[23:34] <b03tz> Works like a charm
[23:34] <b03tz> Thank you sir.

[23:37] <gordonDrogon> how are you driving the SPI bus?
