[17:53] <reider59> I recall reading the actual bit that boots is very very small.
[17:53] <gordonDrogon> reider59, I made hanf a dozen fruit scones last night for guests - all gone!
[17:53] <ReggieUK> just a thought, I wonder if walther needs a hub at all, if it's just got the usb drive in it and the usb drive is externally powered, that should be good enough
[17:53] <gordonDrogon> reider59, home bake == double points ;-)
[17:53] <ReggieUK> I've just read back and he didn't mention anything else plugged into the hub did he?
[17:54] <reider59> I like plain scones etc, only one in the family who does. If I made them at home I`d deffo get minus points
[17:54] <gordonDrogon> reider59, heh... just add sugar and rasins :) (not currants!)
[17:54] * NisseDILLIGAF (~NisseDILL@h-153-177.a218.priv.bahnhof.se) has joined #raspberrypi
[17:54] * PiBot sets mode +v NisseDILLIGAF
[17:54] <MadJ> Is there no Bare bones, BIOS like code for rPi, which performs a POST ? Put onto the SD card and turn on for POST
[17:54] <gordonDrogon> currants -> rabbit poo. Nice plumptious rasins :)
[17:55] <WASDx> What does it mean when the OK blink when the system is running?
[17:55] <ReggieUK> yeah, it's called the platform code
[17:55] <gordonDrogon> MadJ, None that I know of.
[17:55] <MadJ> There is no way to know if the issue is with my SD card or the board is faulty :(
[17:55] <gordonDrogon> MadJ, at least try the software I've put up for you...
[17:55] <MadJ> gordonDrogon: I want to make one, how do i go about it ? I've some experience working into embedded systems
[17:56] <reider59> oh nooooooo! Don`t spoil my plain scones. Sometimes I get Devonshire scones, but they`re a little heavy. If they bake them properly in Asda I can eat them if fresh. But they have to be plain, maybe butter on, occasionally a little spread of jam mmmm
[17:56] <MadJ> gordonDrogon: I am not at home now, will go back in some time and give it a try
[17:56] <gordonDrogon> MadJ, the issue is that no-one will tell you how to program the GPU, so you're going to have to rely on the GPU booting first before it loads your own ARM code.
[17:56] * ctyler is now known as ctyler_away
[17:57] <MadJ> gordonDrogon: Broadcom did release the Datasheet, it does not contain anything related to the GPU ? (Sorry for my ignorance)
[17:57] <ReggieUK> what information do you want from a POST?
[17:57] * sjc (~sjc@ has joined #raspberrypi
[17:57] * PiBot sets mode +v sjc
[17:57] <gordonDrogon> MadJ, that's right - nothing about the GPU, just the ARM.
[17:57] * sjc is now known as sjc_
[17:57] <MadJ> gordonDrogon: Feels stuck :(
[17:57] * Delboy_ is now known as Delboy
[17:57] <Gadgetoid> MadJ: try another SD card?...
[17:57] <gordonDrogon> just buy another SD card.
[17:58] <MadJ> Gadgetoid: Yeah, will do that as well, after trying gordonDrogon 's suggestion
[17:58] <Gadgetoid> If you get into the spirit of Pi, you'll probably want a hundred of the things anyway!
[17:58] <Gadgetoid> My known working SD cards don't boot half the time, just for giggles
[17:58] <ReggieUK> get microSD with an adapter
[17:58] <ReggieUK> then at least you can use it in other stuff too
[17:58] <traeak> that seems to be all i have microsd with adapters
[17:59] <traeak> hard to tell which adapters are populated and which arent though
[17:59] <Gadgetoid> What other stuff takes MicroSD? bar phones where the manufacturers are too damned cheap to include any flash
[17:59] <traeak> almost all tablets do microsd
[18:00] <Gadgetoid> tablets??? microsd? there are no words!
[18:00] <MadJ> lol :P
[18:00] * bionicRobot (~bionic@LPuteaux-156-16-24-172.w82-127.abo.wanadoo.fr) Quit (Quit: bionicRobot)
[18:00] <Gadgetoid> Almost as if they struggled to get it down from 20" to 10", and just had to let that full-sized SD slot go!
[18:00] <ReggieUK> psp, zipit z2, mp3 player, pi, all have different card needs that can be serviced by a microSD :)
[18:00] <MadJ> all the phones that support external memory use microSD
[18:01] <traeak> psp? that's sonly's memsstick crap
[18:01] * ChanServ sets mode -v mikey_w
[18:01] <Gadgetoid> Does the psp Go not use MicroSD? I know the Vita uses some godawful proprietary card, cos I had to sell my grandma to buy one
[18:01] * Pe3k (~kmet@neuron-ai.fei.tuke.sk) Quit (Quit: Lost terminal)
[18:01] <mervaka> my pi's running off a microsd in a sd sleeve
[18:02] <Gadgetoid> I live in the magical world of Apple, where microsd is a mythical beast of lore and legend
[18:02] <traeak> i think i have 4 of those layingn around here, and an acncient 1GB full sd card
[18:02] * Kanerix (~kanerix@reverse.control4.com) Quit (Read error: Connection reset by peer)
[18:02] <dirty_d> i have a 128MB sd card

[18:02] * PiBot sets mode +v [SkG]
[18:02] <dirty_d> it cost $75 when i bought it
[18:02] <gordonDrogon> I have some kingston microSDs in adapters that work fine.
[18:02] <Gadgetoid> dirty_d: amazing how far we've come, eh!
[18:03] <dirty_d> absolutely
[18:03] <gordonDrogon> Hey - my camera has a 1GB IBM MicroDrive in it !
[18:03] <gordonDrogon> and it's still going strong...
[18:03] <Gadgetoid> If I were just a tad older, i'd have experienced the full gamut of computer evolution

[18:03] * PiBot sets mode +v si
[18:03] * PiBot sets mode +v si
[18:03] <gordonDrogon> I think I've had that camera for almost 10 years now.
[18:03] <Gadgetoid> gordonDrogon: almost enough space for one whole photo!
[18:03] <gordonDrogon> Gadgetoid, Heh... it's only 5MP!
[18:03] <Terranigma> i have a samsung class 10 32gb microsdhc in sd sleeve that works fine too
[18:04] <Gadgetoid> We've come from bytes and bits on drum-sized drives, to gigabytes we could easily lose tens of up our nasal passages
[18:04] <yggdrasil> how can i check what groups a user is part of ?
[18:04] <gordonDrogon> yggdrasil, with the 'id' command.
[18:05] <yggdrasil> great thanks
[18:05] <Gadgetoid> Extrapolating from that, in another 20 years we'll have petabytes on cards so small we'll need magnetic field manipulation to pick them up and insert them into our devices
[18:05] * markbook (~markbook@ has joined #raspberrypi
[18:05] * PiBot sets mode +v markbook
[18:05] <dirty_d> lol
[18:05] <Gadgetoid> And you could sneeze the whole internet!
[18:05] <reider59> My Android phone is only a San Francisco 2. I took a pic of an old building (I have a thing about old buildings) here in my home town and printed it out to A4. I was gobsmacked by the change in quality these phones and cameras have undergone!
[18:06] <reider59> The pic looked like it came from a good quality camera
[18:06] * Behold (~behold@unaffiliated/beholdmyglory) has joined #raspberrypi
[18:06] * PiBot sets mode +v Behold
[18:06] <MadJ> The BCM 2835 has no Program Memory ???
[18:06] <ReggieUK> ?
[18:07] <reider59> It was an ex Post Office building converted to a bistro etc but the old architecture remained outside
[18:07] <ReggieUK> there will likely be a little bit of memory knocking around the gpu that we won't have access to but other than that, nope, it's ram or nada
[18:08] <mervaka> mmm
[18:08] <MadJ> ReggieUK: Sticking up an EEPROM for a bootloader would have helped
[18:08] * Veryevil (~Veryevil@ Quit ()
[18:08] <mervaka> so, the PWM on the 3.5mm lack
[18:08] <mervaka> jack*
[18:08] * D34TH (D34TH@unaffiliated/d34th) has joined #raspberrypi
[18:08] * PiBot sets mode +v D34TH
[18:08] <MadJ> ReggieUK: but then again the BOM :(
[18:08] <ReggieUK> and it's unecessary
[18:08] <mervaka> is that a channel each on tip and ring?
[18:09] <mervaka> and can i grab both of those for servo control (with some dubious wiring)
[18:09] * BeholdMyGlory (~behold@unaffiliated/beholdmyglory) Quit (Ping timeout: 246 seconds)
[18:09] <ReggieUK> no idea but the schematics are on the wiki I believe
[18:09] <mervaka> ok
[18:09] <ReggieUK> if not, search http://www.raspberrypi.org/ for schematic and it'll return the relevant post
[18:10] <gordonDrogon> MadJ, It has a rom with enough code to load the bootloader off the SD card...
[18:10] <dirty_d> mervaka, i dont think youre going to be able to reliably operate a servo with the rpi
[18:10] <ReggieUK> that's internal though isn't it?
[18:10] <dirty_d> maybe if you create a real time patched kernel
[18:10] <MadJ> gordonDrogon: rom inside the Broadcom SoC ? or External
[18:11] <gordonDrogon> you can set a servo position with the PWM output - if it's a PWM servo (RC type) you don't need real-time control for that.
[18:11] <gordonDrogon> MadJ, inside the soc.
[18:11] <dirty_d> i think your best bet is to interface a $3 microcontroler over i2c and let the uc to the hard realtime servo control
[18:11] <MadJ> gordonDrogon: Oh, why did they not add a blinky LED code to the firmware then :(
[18:11] <dirty_d> and just send commands over i2c
[18:11] <gordonDrogon> MadJ, because it's a general purpose chip and Broadcom don't know what the end-user is going to do with it.
[18:12] <MadJ> gordonDrogon: So you mean to say Broadcom added the code to load the bootloader, i thought it were the rPi guys, my bad
[18:13] <gordonDrogon> MadJ, I don't know - however it was guys what work for Broadcom that write the bootloader(s) for Linux to run on the Pi.
[18:13] <gordonDrogon> AIUI.
[18:14] <MadJ> gordonDrogon: i see, anyway i am heading home, to try out the files you sent
[18:14] <gordonDrogon> MadJ, ok...
[18:14] <MadJ> gordonDrogon: are you @drogon on twitter ?
[18:14] <gordonDrogon> MadJ, yes.
[18:14] <MadJ> gordonDrogon: cool :) following now

[18:15] <gordonDrogon> I'm not that active - tend to come & go :)
[18:16] <MadJ> gordonDrogon: The Game Port IO tweet was RTed by rPi guys and thats how i know your handle
[18:16] * NIN101 (~NIN@p5DD28CF1.dip0.t-ipconnect.de) has joined #raspberrypi
[18:16] * PiBot sets mode +v NIN101
[18:17] <dirty_d> gordonDrogon, you dont want jitter in the pwm signal
[18:17] <dirty_d> its a 1-2ms pulse
[18:18] <dirty_d> ideally youd want something like 1000 steps of resolution
[18:18] <dirty_d> youre not gonna get that in a userspace program on linux
[18:19] <mervaka> hmm
[18:19] <dirty_d> the hardware pwm might be able to
[18:19] <dirty_d> but its only 1 channel right?
[18:19] <gordonDrogon> dirty_d, RC PWM is positional, not speed (usually)
[18:19] <dirty_d> you need two, one for esc and one for steering servo
[18:19] <mervaka> gpio pwm and audio are on totally separate pins from the bcm
[18:19] <dirty_d> gordonDrogon, yes
[18:20] <dirty_d> whats the pwm resolution?
[18:20] <gordonDrogon> RC PWM is horrible )-:
[18:20] <dirty_d> its not really pwm
[18:20] <dirty_d> its just pulse length control
[18:20] <gordonDrogon> it's an abomination that should have been dumped years ago.
[18:20] <dirty_d> the spacing between pulses doesnt really matter
[18:20] <dirty_d> you can send a 1-2ms pulse at 50Hz or upto even 400Hz
[18:20] <gordonDrogon> After 25 year of non RC stuff, I refreshed my memories last year and was gob-smacked to find it hadn't changed.
[18:21] <gordonDrogon> PPM - multiplexed PWM over radio to the servo controller. *sigh*
[18:21] * wej (~j@ Quit (Ping timeout: 248 seconds)
[18:21] * MadJ (~chatzilla@ Quit (Quit: ChatZilla [Firefox 12.0/20120420145725])
[18:21] <dirty_d> i use the new 2.4GHz stuff
[18:21] <gordonDrogon> what was worse, modern ESCs were taking the PWM, decoding it, then re-coding it to the motors (brushless DC)
[18:22] <dirty_d> whats a better alternative?
[18:22] <gordonDrogon> I put together a whole new system for a client, but sadly they didn't cough up all the money they promised )-:
[18:22] * stev (steven@114-42-67-38.dynamic.hinet.net) Quit (Quit: Leaving)
[18:22] * katnegermis (~katnegerm@ Quit (Ping timeout: 265 seconds)
[18:22] <dirty_d> just send the desired pwm signal to drive the motors with?
[18:22] <dirty_d> and let the controller commutate?
[18:22] <gordonDrogon> the alternative is to send high-level commands to the remote vehicle.
[18:23] <gordonDrogon> not even pwm. just send it a heading and speed and height..
[18:23] * wej (~j@ has joined #raspberrypi
[18:23] * PiBot sets mode +v wej
[18:23] <gordonDrogon> I had a complete "stick twiddling" free system.
[18:23] <gordonDrogon> the few RC "purists" I talked to were aghast...
[18:24] <dirty_d> seems too high level for an esc
[18:24] <gordonDrogon> Push a button - the craft takes off and hovers on it's own - no stick twiddling needed.
[18:24] <mervaka> how dare you cut them out the hobby?
[18:24] <dirty_d> thats on a like a flight controller level
[18:24] <dirty_d> thats what i did for my quadcopter
[18:24] <gordonDrogon> this was for multicopters.
[18:24] <dirty_d> there is a board that takes input from the radio and processes it and sends out signals to control ESCs
[18:25] <gordonDrogon> My hand-held controller was a PC joystick thing.
[18:25] <SpeedEvil> The problem is that you rely completely on your position solution, if you lose the 'real' control.
[18:25] <mervaka> PID controller?
[18:25] <mervaka> or state space?
[18:25] <dirty_d> my thing is a pid controller
[18:25] <mervaka> :)
[18:25] <gordonDrogon> I did PID as it was easy to start with.
[18:25] <dirty_d> with a nice gyro/accel
[18:25] <mervaka> gotta learn state space next year at uni
[18:25] <mervaka> resenting the exam at the end..
[18:25] <Walther> just curious, why does the gpu chip get hot as well even though i'm just running ssh?
[18:25] <gordonDrogon> SpeedEvil, relying on the on-board sensors was fine - that was expected for my project.
[18:26] <RITRedbeard> they're all housed in the same SoC, correct?
[18:26] <dirty_d> i still need to tune it to get it to fly
[18:26] <dirty_d> ive only tried to fly it twice
[18:26] <gordonDrogon> the gpu and memory share the same footprint - memory is on-top of the gpu which contains the arm.
[18:26] <RITRedbeard> if they're in the same package... yeah
[18:27] <gordonDrogon> I never got anything off the ground - if I had more time of my own, (and more toy money) I'd pursue it
[18:27] <RITRedbeard> I'm in a similar prediciment.
[18:27] <gordonDrogon> I bought lots of sensors, IMU boards, etc. mostly based on the Ardu Pilot Mega though.
[18:27] <RITRedbeard> I did get a pusher big wing trainer to fly
[18:27] <Walther> gordonDrogon: gpu != cpu
[18:27] <RITRedbeard> about 20-30 min of flight time
[18:27] <mikey_w> Just put it on the ground and kickstart it.
[18:28] <RITRedbeard> then I decided that I had enough of IL-2 1946 to fly 800mm wingspan warbirds
[18:28] <RITRedbeard> lol, what a pain in the knee
[18:28] <dirty_d> gordonDrogon, this is mine http://www.youtube.com/watch?v=cBCbTRqPMTY
[18:28] <RITRedbeard> nose crash, oops, the coilet won't close all the way
[18:28] <RITRedbeard> oops chipped your prop
[18:28] <mervaka> you guys have seen the agressive flying algorithms some guys at berkeley (i think) wrote for quadcopters?
[18:28] <dirty_d> i made the controller board and software from scratch for fun
[18:29] <RITRedbeard> I never got a warbird off the ground, the 800mm ones, I think I was suffering from takeoff stall
[18:29] <RITRedbeard> not enough RAS to go up, up, up
[18:29] <RITRedbeard> weird phenomenon, really

[18:31] <Walther> No, but you said that the *gpu* was with the ram at the middle, I thought it was cpu
[18:32] <gordonDrogon> mervaka, yea, they've got some neat stuff there- I think they're using Atom processors too.

[18:33] <mervaka> i've been looking for someone to buy my eeebox..

[18:33] <gordonDrogon> that's the place I saw then flying upside down and sticking with velcro, and sideways through a slot, etc. ?
[18:33] <dirty_d> i saw that
[18:33] <gordonDrogon> Walther, the smaller big chip is the USB hub and ethernet controller.
[18:33] <mikey_w> Ram?
[18:34] <Walther> gordonDrogon: ahh, that explains why it gets hot :D
[18:34] <gordonDrogon> the RAM is physically on-top of the GPU SoC.
[18:34] <RITRedbeard> atom for flying platform?
[18:34] <RITRedbeard> Yes, the RAM is PoP (package on package)
[18:34] <Walther> kghost: your pi or computer?
[18:34] <dirty_d> bga sandwich?
[18:34] <RITRedbeard> it's all in the same die
[18:34] <RITRedbeard> righto
[18:34] <gordonDrogon> that's why you can't hand-solder them...
[18:34] <kghost> Walther: sure my pi
[18:34] <Walther> Oh neato, tell me your results later
[18:34] <mervaka> why is everything going bga :(
[18:34] <RITRedbeard> a big fat BGA sandwich, wonder how it effects thermals
[18:35] <RITRedbeard> which leads me to my math question
[18:35] <gordonDrogon> see if I can dig up a reference to those quadcopters.
[18:35] <traeak> math is hard

[18:37] <Walther> Downloading a big file leads to Pi crashing- ssh session hangs and it timeouts all requests
[18:37] <dirty_d> whats the problem?
[18:38] <mikey_w> Bad software.

[18:49] <yggdrasil> i just usually compile stuff on what im using..
[18:49] <gordonDrogon> because it's a PITA to then copy the binaries over or arrange nfs, etc.
[18:49] <Walther> I've compiled the entire kernel in sub30 s on my virtual private :P
[18:49] <Lartza> Also since I can't get omxplayer to even compile on the pi how would I get it to cross-compile

[18:50] <Lartza> :)
[18:50] <yggdrasil> Lartza: wheezy is pretty complete
[18:50] <gordonDrogon> I don't have anything really big to compile though.
[18:50] <yggdrasil> i have a 2gb sd card too.
[18:50] <kghost> is the big chip contains all cpu/gpu/sdram ?
[18:50] <Lartza> gordonDrogon, Libreoffice or firefox would be nice easy ones for the Pi
[18:50] <andatche> Walther: a complete kernel compile from a clean source tree in under 30s? I'd like to see that
[18:51] <gordonDrogon> Lartza, Ha.. they won't even run, even if you could compile them!!!
[18:51] <Lartza> gordonDrogon, Well it would take some time ;)
[18:51] <Walther> andatche: let's say the server has 6x 4-core xeons, 144GB ram...
[18:51] <Lartza> Firefox on my desktops usually took a couple hours
[18:51] <gordonDrogon> make -j
[18:51] <Walther> andatche: and yes, make -j 25
[18:51] <Lartza> libreoffice I haven't even tried to compile :S
[18:52] <andatche> even on a 16-core box with 16GB ram, compiling a hefty kernel config takes considerably longer than that
[18:52] <NucWin`> i tried to compile xbmc on arch yesterday but after 3+ hours i wanted to go out and take pi so had to stop it
[18:52] <Walther> gordonDrogon: looks like the kernel memory increase solved the issue, at least so far so good
[18:52] <andatche> the standard RHEL kernel config takes about 20 mins
[18:52] <Lartza> andatche, Standard confgis suck
[18:52] <Walther> gordonDrogon: is that documented / going to be implemented by default soon?
[18:52] <gordonDrogon> IS Debian wheezy still armel - ie. soft FP? If so, when I really don't undestand why anyone would even consider it when Raspbian offers the same thing with hard FP...
[18:52] <yggdrasil> anyone here running pi on battery ?
[18:52] <Lartza> andatche, Standard ARch config compile time is like that 20 minutes but on gentoo when you only enable what you need it's few minutes
[18:53] <gordonDrogon> Walther, good-oh. as for documented? Who knows - I picked it up here, so ...
[18:53] <andatche> Lartza: well, yeah, a tiny cutdown config will compile quickly
[18:53] <Walther> andatche: Again, I've done sub30s on 24core@3.somethingGhz 144GB
[18:53] <Walther> gordonDrogon: Also, what was the other tweak you mentioned?
[18:53] <Walther> andatche: you just have to make -j :)
[18:53] <Lartza> I hate that whezy comes with all crap preinstalled :(
[18:54] <gordonDrogon> Walther, put smsc95xx.turbo_mode=N in /boot/cmdline.txt

[18:54] <Walther> gordonDrogon: pros/cons of that; what does it do?
[18:54] <Walther> andatche: good :P

[18:55] <andatche> thought so, the freeze is impending

[18:56] <Lartza> NucWin`, Seems it has a bad package selection
[18:56] <gordonDrogon> Walther, again, I'm not 100%, but it solved the issue for me - but I suspect it does what it says - takes the ethernet chip out of 'turbo' mode...
[18:56] <NucWin`> what you mean? not got packages you want?
[18:56] <gordonDrogon> wheezy is testing... squeeze is stable.
[18:56] <Lartza> NucWin`, Yeah
[18:57] <NucWin`> there are PKGBUILD files though for most stuff
[18:57] <reider59> Personally, I find Wheezy beta more stable than Squeeze
[18:57] <reider59> and faster
[18:57] <gordonDrogon> I'm just using raspbian...
[18:57] <yggdrasil> it was a lot easier to get my wireless adapter working
[18:57] <Lartza> reider59, But wheezy beta or raspbian?
[18:58] <reider59> I tried Raspbian but I`m happy with the Wheezy Beta for full time use
[18:58] <Lartza> gordonDrogon, Does raspbian update firmware from the repos?
[18:58] <mervaka> got my ralink wireless adapter working under the standard debian image
[18:59] <reider59> Mind you, if this update ever finishes I may change my mind. Last time I lost the use of wired and WiFi network in Squeeze
[19:01] <Walther> i'm not sure which version I'm running, an easy way to check?

[19:06] <yggdrasil> WASDx: i only approve of it if that webserver is running on a pi
[19:06] <reider59> Both working, now that,s an improvement. the newer install script for my WiFi adapter can allegedly cope with an update but I haven`t installed that one yet.
[19:06] <andatche> Walther: squeeze
[19:06] <WASDx> yggdrasil: Yes. I got mine today
[19:06] <mikey_w> Newark has processed my Pi and I should get a tracking number soon.
[19:06] <yggdrasil> nice i got mine 2 days ago :)
[19:06] <reider59> Yes, I really like Wheezy and that`s the one I`m sticking with
[19:06] <yggdrasil> this # will really be hopping this weekend.
[19:07] <Walther> Is there a difference between spueeze and wheezy, if not for the GUI/desktop/X?

[19:30] <gordonDrogon> MadJ, hm. well I don't know. I only run/support debian stable or raspbian, but you can try to ssh into it, but I suspect it's not running sshd.
[19:30] <dirty_d> Walther, --output-document=file
[19:30] <MadJ> gordonDrogon: its running SSHd
[19:30] <yggdrasil> gordonDrogon: what do you think about battry running the pi ?
[19:30] <gordonDrogon> yggdrasil, get a big battery.

[19:31] <gordonDrogon> yggdrasil, if you assume 500mA with no USB peripherals, then base the calcs around that then you'll build in some spare...

[19:32] <gordonDrogon> MadJ, are you using hdmi or composite?
[19:32] <MadJ> gordonDrogon: Tried connecting it to a HDMI projector, nothing showed up.
[19:33] <MadJ> gordonDrogon: Now its not connected to any display
[19:33] <MadJ> gordonDrogon: should i try composite ?
[19:33] <gordonDrogon> MadJ, it needs to be plugged in at boot time. if it's not there it will default to the composite output.
[19:33] <gordonDrogon> if the projector has composite, you can try that too.
[19:33] <MadJ> gordonDrogon: Ok ill try

[19:35] <gordonDrogon> MadJ, the .bin files are the GPU startup code the start.elf is the thing that sets the memory split for the GPU/ARM and kernel.img in the kernel I compiled for my own Pi.
[19:36] <dirty_d> MadJ, config.txt on the fat32 partition
[19:36] <MadJ> dirty_d: Ok
[19:36] <gordonDrogon> MadJ, you *may* now wish to do an update ; apt-get update ; apt-get upgrade, then install the rpi-update program and run that too...
[19:36] <gordonDrogon> MadJ, my Kernel does not have all the device drivers that some peopel want - e.g. no wifi...
[19:36] <MadJ> gordonDrogon: I see. The file size of kernal.img was different, rest all files were of same size as existing ones
[19:36] <dirty_d> MadJ, possible modes are here http://elinux.org/RPi_config.txt
[19:37] <MadJ> dirty_d: Thanks !
[19:37] <gordonDrogon> MadJ, same size doesn't neccessarily mean same contents.
[19:37] <MadJ> gordonDrogon: true
[19:37] <dirty_d> no prob
[19:37] <gordonDrogon> you can use the 'cmp' command to compare.
[19:38] <Walther> So far, the wget to /dev/null hasn't crashed the system
[19:38] <Walther> So apparently it is high throughput that causes the issue
[19:38] <gordonDrogon> Walther, or the SD card driver.
[19:38] <dirty_d> the usb hdd also crashed though right?
[19:38] <Walther> gordonDrogon: reproducible on ext hdd
[19:38] <dirty_d> what happens when it crashes?
[19:38] <dirty_d> kernel panic?
[19:39] <gordonDrogon> let me try ..
[19:39] <Walther> oh fuck, it just crashed anyway
[19:39] <dirty_d> well thats good i guess
[19:39] <dirty_d> at least its not something hard drive related
[19:39] <Walther> ssh hangs - and the whole pi becomes unresponsive
[19:39] <Walther> not able to reconnect
[19:39] <dirty_d> Walther, maybe it runs out of memory?
[19:39] <dirty_d> although i wouldnt think wget sues a lot

[19:40] <mervaka> ooooo
[19:40] <mervaka> along with my rc nitro car
[19:40] <gordonDrogon> I'd wait a while to see if it comes back ...
[19:40] <mervaka> i found 20 NiMH AAs
[19:40] <Walther> gordonDrogon: done that, doesn't
[19:40] <dirty_d> Walther, you havent connected it to a display to see what really happens?
[19:40] <Walther> dirty_d: no can do, don't have a monitor with hdmi or composite, only dvi
[19:40] <dirty_d> ahh
[19:41] <Walther> ssh is my only option for now
[19:41] <dirty_d> isnt there a log file you can look at?
[19:41] <NucWin`> my monitor not having hdmi has been annoying me
[19:41] <dirty_d> or at least set one up
[19:41] <gordonDrogon> only a log-file if it gets written to before it crashes...
[19:41] <NucWin`> have to fight over the tv
[19:41] <dirty_d> just get an hdmi -> DVI adapter

[19:43] <gordonDrogon> Walther, ah well. on't know what next if you're all u pto date with kernel, software/ firmware, etc.
[19:43] <NucWin`> could it not be that your monitor understadnds hdmi but doesnt have the port
[19:43] <gordonDrogon> not me.

[20:05] <dirty_d> Walther, i doubt its defective
[20:05] <Draylor> that kernel is defective in various ways
[20:05] <gordonDrogon> give mine a go - even though it might not support wifi, etc. it might give you an indication.
[20:05] <Draylor> update it & it'll be better
[20:05] <gordonDrogon> yes, or run rpi-update - I'm sure that pulls in a newer one now...
[20:06] <Walther> gordonDrogon: apt-get update && upgrade doesn't work?

[20:17] <plugwash> you don't want a seek parameter
[20:17] <plugwash> it will go much faster if you use a larger blocksize

[20:17] <markbook> err.
[20:17] <markbook> 1024K
[20:17] <markbook> 1M
[20:18] <plugwash> and at least in my experiance on normal computers the SD card device isn't usually called mmcblk0 (though i've seen one laptop where it was)
[20:18] <markbook> the target is likely to be /sdN
[20:18] <yggdrasil> hmm
[20:18] <yggdrasil> no its that
[20:18] <markbook> on linux
[20:18] <yggdrasil> i think

[20:18] <yggdrasil> [13584.941654] mmc0: new SD card at address 5974
[20:19] <arfonzo> yggdrasil: correct. It's /dev/mmcblk* on arch.
[20:19] <markbook> (mine on fedora appear to udev as /dev/sdc since I have two SDD devices)
[20:19] <buzzkill> markbook: my centos distro is referring to it as /dev/mmcblk0
[20:19] <markbook> fair enough
[20:19] <yggdrasil> hmm yet it does not work.
[20:19] <lennard> it probably depends mostly on wether its a 'native' sdcard device or essentially an integrated usb adapter

[21:03] <mervaka> yup :/
[21:04] <dirty_d> avr is so simple
[21:04] <mervaka> well
[21:04] <mervaka> avr/pic/etc is very straightforward
[21:04] <gooseberry> it's not nice of them to bill on dispatch, it's standard practice
[21:04] <mervaka> they're microcontrollers
[21:04] <dirty_d> mervaka, do you have a scope or anything to look at the signal?
[21:04] <gooseberry> it would be super scummy of them to hold onto your money for 2 months earning interest on it
[21:05] <mervaka> dirty_d: nope, just a spare servo
[21:05] <dirty_d> mervaka, im not even really sure what pwmWrite does
[21:05] <mervaka> dirty_d: i have scopes at uni, but that's 1h20m away
[21:05] <mervaka> dirty_d: and daytime
[21:05] <dirty_d> i would hope it just sets the duty cycle
[21:06] <mervaka> well thats what pwm is

[21:07] <mervaka> btw, the breakouts i need are on R21 and R27
[21:07] <dirty_d> but
[21:07] <mervaka> 270R resistors

[21:08] <gordonDrogon> I couldn't find any actual manual on programming the counters...
[21:08] <mervaka> could 600k be too high for some servos?
[21:08] <dirty_d> i think the pwm freq is therefore 585Hz
[21:08] <mervaka> if not all
[21:08] <gordonDrogon> very probably.

[21:08] <dirty_d> mervaka, im pretty sure thats the counter frequency

[21:08] <dirty_d> so if the counter "top" value is 1024
[21:08] <gordonDrogon> going to get some supper. back later.
[21:08] <dirty_d> the actual pwm freq would be 585Hz
[21:08] <dirty_d> but im not sure if thats how this pwm actually works
[21:08] <dirty_d> the datasheet sucks
[21:08] <mervaka> assuming a certain step size ofc
[21:09] <dirty_d> yea
[21:09] <mervaka> it could be any number of steps for a given frequency
[21:09] <dirty_d> the divider is 32, so you cna have a much higher freq
[21:09] <dirty_d> or lower
[21:09] <mervaka> depends on the peripheral
[21:09] <mervaka> well analogue servos cant do very high frequencies at all
[21:10] <mervaka> digital apparently want a few hundred hz
[21:10] <dirty_d> 50Hz right
[21:10] <mervaka> yeah, for analogue
[21:10] <dirty_d> theres a very big problem with that though
[21:10] <dirty_d> thats 50Hz
[21:10] <dirty_d> or a 20ms period
[21:10] <dirty_d> the actual information is encoded in the length of the pulse
[21:10] <dirty_d> which is 1-2ms
[21:10] <mervaka> yeah
[21:10] <WASDx> What does the OK led mean? It blinks occasionally for me
[21:11] <gooseberry> zzzzzzzzzzzzzzzzzzzzzzzzzz
[21:11] <dirty_d> so 90% of your resolution is lost to that 18ms

[21:11] * PiBot sets mode +v paultag
[21:11] <dirty_d> mervaka, yea the servos position is determined by a pulse from 1-2ms
[21:11] <ReggieUK> it's set to mmc in the board code
[21:11] <WASDx> Yeah I heard it could be
[21:11] <dirty_d> but the pwm period os 20ms
[21:11] <paultag> Anyone have handy guides on how to rebuild pi images?
[21:11] <dirty_d> is*
[21:11] <ReggieUK> which suggests that you can attach it to other devices

[21:13] * PiBot sets mode +vvvv Viaken Walther Xark yasaii
[21:13] <dirty_d> well i dunno about the analog ones
[21:13] <mervaka> higher frequencies equal smaller high periods
[21:13] <mervaka> ofc
[21:13] <dirty_d> i know most ESCs dont care about the frequency
[21:13] <dirty_d> just the pulse length
[21:13] <mervaka> ya
[21:13] <dirty_d> but its ok
[21:13] <dirty_d> you can do 50Hz
[21:13] <dirty_d> just need to use a higher "top value"
[21:13] <dirty_d> im not sure what the max is
[21:13] * Gadget-Mac (~swp@ has joined #raspberrypi
[21:13] * PiBot sets mode +v Gadget-Mac
[21:14] <dirty_d> but if its 65535
[21:14] <mervaka> would depend on the servo
[21:14] <dirty_d> thats only 9Hz
[21:14] <dirty_d> so you want a 1.2MHz counter freq
[21:14] <mervaka> i think you're ahead of me :p
[21:14] <mervaka> i've taken time out to wash the dishes
[21:14] <dirty_d> with a top of 65535 that gives you about 18Hz
[21:15] <dirty_d> you still have decent resolution to vary the duty cycle

[22:04] <dirty_d> so ti works?
[22:04] <dirty_d> it
[22:04] <dirty_d> make a loop
[22:04] <dirty_d> so you can enter a pwm value

[22:08] <mervaka> heh
[22:08] <dirty_d> thats good
[22:08] <mervaka> yes
[22:08] <mervaka> very good
[22:08] <dirty_d> super
[22:09] <dirty_d> so that adio is 2 channels each of which is a pwm ouput?
[22:09] <dirty_d> audio
[22:09] <mervaka> the 3.5mm jack is filtered pwm
[22:09] <mervaka> check the schematic
[22:09] <dirty_d> ahh
[22:09] <dirty_d> filtered
[22:09] <Walther> guys, a wuick check - what is pwm?
[22:09] <mervaka> we want to tap in before R21 and R27 respectively
[22:10] <mervaka> so to get pwm1 it requires some rework
[22:10] <mervaka> Walther: pulse width modulation
[22:10] <dirty_d> youer using pwm2?
[22:10] <mervaka> dirty_d: no
[22:10] <mervaka> currently using the gpio
[22:10] <dirty_d> hmm?
[22:10] <dirty_d> but its in pwm mode

[22:11] <mervaka> pwm0 can appear on more than one pin
[22:11] <mervaka> as can pwm1
[22:11] <dirty_d> so why mess with resistors
[22:11] <mervaka> because pwm1 isnt available on the gpio header
[22:11] <dirty_d> Walther, pulse width modulation
[22:11] <dirty_d> sounds more complicated than it is
[22:11] <mervaka> but you can get to it with a little rework
[22:11] <mervaka> nah
[22:11] <dirty_d> oh ok
[22:11] <mervaka> http://elinux.org/RPi_BCM2835_GPIOs
[22:12] <dirty_d> so then you are using pwm2
[22:12] <mervaka> i was using gpio18 just now
[22:12] <mervaka> which has pwm0
[22:12] <dirty_d> oh 0
[22:12] <mervaka> i'm suggesting we use gpio40/45
[22:12] <Walther> I'm taking more of a server approach here :) I just took apart a SATA HDD USB dock
[22:12] <mervaka> which is used for the headphones
[22:13] <Walther> I'm going to build a case for the Pi and a sata drive or two
[22:13] <mervaka> so i'm going to stick dropwires onto R21/R27
[22:13] <mervaka> put them through current limiting resistors
[22:13] <mervaka> and voila, two channels of pwm, hopefully
[22:13] <dirty_d> cool
[22:13] <dirty_d> you should try to change the frequency

[22:17] <dirty_d> *(pwm + PWM0_RANGE) = 0x400 ;
[22:17] <dirty_d> change to *(pwm + PWM0_RANGE) = 24000;
[22:18] <dirty_d> same for PWM1_RANGE
[22:18] <dirty_d> that should give you a 50Hz PWM signal with enough resolution to use with a servo
[22:19] <SpeedEvil> Is this hardware PWM?
[22:19] <dirty_d> yea
[22:19] <mervaka> SpeedEvil: same pwm modules that the audio uses
[22:19] <SpeedEvil> Ah - I diddn't know that was properly exposed - neat
[22:19] <mervaka> gordonDrogon: yes. offhand, do you know if it's possible to address bcm gpio channels 40 and 45?
[22:20] <mervaka> gordonDrogon: http://elinux.org/RPi_BCM2835_GPIOs
[22:20] <dirty_d> mervaka, if you do that a pwm value of 2400 should give you a 1ms pulse, and 2400 a 2ms pulse
[22:20] * JMichaelX (~james@ Quit (Remote host closed the connection)
[22:20] <dirty_d> sorry, 1200 a 1ms pulse
[22:20] * jprvita is now known as jprvita|afk
[22:21] <dirty_d> so you effectiveley have 1000 servo steps
[22:21] <dirty_d> should be enough resolution right?
[22:21] <dirty_d> you could get more by increasing the clock freq and raising the range from 24000
[22:22] <dirty_d> i could be wrong though, im not entireley sure this PWM peripheral works how i think it does

[22:25] <mervaka> again, the LPF would probably bork that about
[22:25] <dirty_d> nah
[22:25] <mervaka> depends on the slew rate
[22:25] <dirty_d> 50Hz is very slow
[22:25] <mervaka> and the frequency we're talking about
[22:25] <dirty_d> it will be a nice square wave on your screen

[22:26] <mervaka> but its broken
[22:27] <mervaka> gordonDrogon: yes. if i can get to BCM GPIO 40/45 then that's excellent :>
[22:28] <dirty_d> mervaka, this is the program i made with a 400Hz servo pulse http://cisweb.bristolcc.edu/~klabs/scope.jpg
[22:28] <mervaka> ah, cool :)
[22:28] * tech2077 is getting a reflective TFT-LCD module for his pi
[22:28] <gordonDrogon> mervaka, the hard part is getting hold of the 2nd PWM output, but I reckon you might be able to solder a wire onto some of the components at the front of the audio output.
[22:29] <mervaka> gordonDrogon: thats the easy part :) R21/R27 are the two resistors before the LPF on each audio channel
[22:29] <mervaka> i'd take off before those
[22:29] <gordonDrogon> mervaka, you already have pwm0 on the GPIO connector.
[22:30] <mervaka> gordonDrogon: yeah, just for continuity's sake :)
[22:30] <mervaka> might even see what i can get through the standard 3.5mm jack, after the LPF
[22:30] <gordonDrogon> it's all the same PWM - I had one chap express surprise that when he was using the pwm on the GPIO it made funny noises on his speakers :)
[22:30] <tech2077> heh
[22:31] <dirty_d> was it a 585Hz tone?
[22:31] <dirty_d> lol
[22:31] <tech2077> theres no simple driver for PWM for the RasPi yet right
[22:31] <dirty_d> gordonDrogon, made one
[22:31] <tech2077> so you have to do good ol' mmap-ing
[22:31] <gordonDrogon> it's just a set value type 'driver'.
[22:31] <tech2077> sysfs?
[22:32] <gordonDrogon> it won't put numbers into it fro a buffer for example...
[22:32] <gordonDrogon> mmap, yes.
[22:32] <tech2077> gordonDrogon, so theres a sysfs based driver for it?
[22:32] <tech2077> or mmap still required
[22:32] <dirty_d> mervaka, you gonna try that with a servo?
[22:33] <tech2077> s/theres/there's/g
[22:33] <mervaka> dirty_d: yeah, just need to sort out some meat for it first.
[22:33] <dirty_d> tech2077, you dont have to use mmap, hes done all that for you already
[22:33] <tech2077> nice
[22:33] <dirty_d> tech2077, you just call a function to set the duty cycle you want
[22:33] <dirty_d> mervaka, youre gonna change the frequency and stuff right?

[22:34] <Trieste> Hi, I just let my RaspPi do a fairly intensive task, and after few seconds, it doesn't respond to ping anymore - is it possible it's overheating?
[22:34] <dirty_d> 1ms is all the way left 2ms is all the way right
[22:34] <dirty_d> or the other way around
[22:34] <dmsuse> ah thanks
[22:34] <gordonDrogon> I essentailly write some wrappers for the whole mmap stuff to keep it sort of sane and "familiar" for people coming from Arduino land.

[23:25] <yggdrasil> So if anyone cares. cmus is the best cli mp3 player
[23:26] <yggdrasil> it can play wmas and playlists and all that
[23:26] <yggdrasil> its pretty full on ncurses gui interface

[23:27] <_inc> wonder what that was about
[23:28] <yggdrasil> thats ... slightly strange?
[23:28] <yggdrasil> they are probobly copying google
[23:28] <_inc> yeaa
[23:28] <yggdrasil> trying to be cool.
[23:29] <_inc> i don't know if they are going to roll out their own devices, i somehow think apple or google will allow it on theirs
[23:29] <gooseberry> tomtom is supplying the backend to apples new map software for i06
[23:29] <yggdrasil> ahh there ya go
[23:29] <_inc> i thought that was Waze?
[23:30] <gooseberry> nah tomtom
[23:30] <_inc> whats the Waze reference in the licensing for?

[23:32] * jprvita is now known as jprvita|afk
[23:32] <_inc> afaik there wasn't a street view alternative to the maps app though? just top-down ariel imagery called "flyby"
[23:33] <gooseberry> _inc: Yeah there are a couple people in the ios 6 beta, at the moment it doesn't look to be as good as google maps but that might change by the time it releases
[23:33] <gooseberry> _inc: and flyby looks really lly buggy

[23:34] <_inc> the technology behind it is amazing
[23:35] <david3x3x3> i'm running raspbmc and sometimes when i play videos i get audio but no video
[23:35] <gooseberry> _inc: they're probably just preparing, remember how long it took google to streetview whole countries, it was a very slow roll-out, and google might not want to sell the mapping data to apple after being ditched
[23:35] <david3x3x3> i assume i'm playing a video with an unsupported codec. is there a way to troubleshoot?
[23:35] * reider59 (56059692@gateway/web/freenode/ip. Quit (Quit: Page closed)
[23:35] <_inc> david3x3x3: what is the video encode?

[23:36] <dirty_d> mervaka, hey i figured out how to get the PWM to work for you
[23:36] <david3x3x3> some are videos played through xbmc add-ons
[23:36] <_inc> like?
[23:36] <david3x3x3> some are .avi files that i can't remember where they came from
[23:36] <dirty_d> right now its in some strange mode, you can put it into a more sensible mode
[23:36] <david3x3x3> like the funny or die add on doesn't display video
[23:36] <dirty_d> mervaka, im testing it with my speakers, lol
[23:36] <_inc> i think that may be webM

[23:38] <mervaka> currently trying to sort out an optoisolator for the pwm signal
[23:38] <mervaka> the servo seems to be sinking current with the 3.3v/5v potential difference
[23:38] <dirty_d> the signal isnt doing what you want
[23:39] <gooseberry> try reversing the polarity
[23:39] <dirty_d> i made a couple changes to wiringpi.c to make it do what you want
[23:40] <dirty_d> has to be in "MS mode"
[23:41] <dirty_d> mervaka, look at likes 440 - 455 http://ideone.com/AJKpO
[23:41] <dirty_d> swap this file for the original wiringpi.c
[23:41] * C-M (~c_m@wikimedia/C-M) Quit (Quit: Leaving...)
[23:41] <dirty_d> and use a PWM value from 1200 to 2400 to control the servo
[23:43] <yggdrasil> where can i find information on the connector on the top of the pi

[23:45] <lowsider> Walther: i have that one
[23:45] <lowsider> i *think* it came with the cord
[23:46] <dirty_d> mervaka, i added PWM0_MS_MODE | PWM1_MS_MODE to *(pwm + PWM_CONTROL) = PWM0_ENABLE | PWM1_ENABLE | PWM0_MS_MODE | PWM1_MS_MODE; to put the pwm peripheral in the right mode
[23:46] <Walther> lowsider: doesn't look like it comes with a cord

[23:50] <yggdrasil> i think there a lot of them.
[23:50] <_inc> also, i thought EAGLE was free? whats going on?!
[23:50] <yggdrasil> uh ?
[23:51] <yggdrasil> its free under a certain size of pcb isnt it ?
