[0:00] * _BigWings_ (~Thunderbi@modemcable237.145-19-135.mc.videotron.ca) Quit (Read error: Connection reset by peer)
[0:03] * VivaPenguinos_ (6cfd5cf3@gateway/web/freenode/ip.108.253.92.243) has joined #raspberrypi
[0:03] <VivaPenguinos_> Hello
[0:04] * _BigWings_ (~Thunderbi@modemcable237.145-19-135.mc.videotron.ca) has joined #raspberrypi
[0:04] <VivaPenguinos_> Can anyone assist me in writing a C++ program for the DS18B20?
[0:04] <VivaPenguinos_> Been searching around for source code
[0:05] <gordonDrogon> is that a 1-wide device?
[0:05] <SpeedEvil> No
[0:05] <VivaPenguinos_> yes
[0:05] <SpeedEvil> It's a one-wire-bus thermometer
[0:05] <VivaPenguinos_> well 1 wire bus
[0:06] <VivaPenguinos_> I wrote it in python but the time it takes to output data from 2 sensors is too much
[0:06] <VivaPenguinos_> I was thinking of writing it in C++ to improve timing
[0:06] <bsdfox> VivaPenguinos_, are you trying to write a driver for it or just want to access the sensor data from your C program?
[0:06] <VivaPenguinos_> Acess data to the C
[0:06] <VivaPenguinos_> Tell it to write in the text file along with a time stamp the temperature
[0:07] <bsdfox> I know linux has OWFS and I think someone wrote a driver for the rpi so you should be able to just read the contents of a file (/sys/bus/w1/etc..) and parse it to get the temp value
[0:07] <gordonDrogon> are you sure it's the program that's slow and not the kernel interfae to the 1w system?
[0:07] <bsdfox> VivaPenguinos_, I would use a different language so it's a 3-5 minute job instead of an hour or more
[0:08] <VivaPenguinos_> it is the program, I can massively optimize it but wondering if it's better to optimize it in Python or just write it in C
[0:08] <nerdboy> python shouldn't be *that* slow...
[0:08] <VivaPenguinos_> 7 seconds before it writes it the second time
[0:08] <bsdfox> mm just read what you wrote above
[0:08] * Thra11_ (~Thra11@87.114.72.212) Quit (Ping timeout: 264 seconds)
[0:09] <bsdfox> VivaPenguinos_, try creating a ramdisk and storing the file there
[0:09] <bsdfox> I bet your SD card is slow
[0:09] <VivaPenguinos_> Using Class 6
[0:09] <bsdfox> or nfs mount or something besides native sd card
[0:09] <nerdboy> VivaPenguinos_: import timing and time some things
[0:09] <VivaPenguinos_> I'm using time to create the timestamp.
[0:09] <nerdboy> see how long it really takes
[0:10] <nerdboy> no, instrument the code
[0:10] <VivaPenguinos_> hmm I'll take a look into it
[0:10] * mumixam_ (~m@unaffiliated/mumixam) Quit (Ping timeout: 240 seconds)
[0:10] <nerdboy> timing.start() do stuff... timing.finish()
[0:11] <VivaPenguinos_> cause the one from adafruit does output quick, but when I add a 2nd sensor it takes a while
[0:11] <VivaPenguinos_> Lemme try the timing
[0:11] <kephra> VivaPenguinos_, Python is slow, and has a bad garbage collector - my compromise is often Lua+C
[0:12] * Dooley (~Dooley@dslb-178-010-116-169.pools.arcor-ip.net) Quit (Quit: Leaving)
[0:12] <nerdboy> lua seems okay/fast enough for some things
[0:12] <VivaPenguinos_> Unfortunately, I haven't used C in over 3 years so I'm pretty rustic
[0:12] <nerdboy> python is faster than you might think if you use included batteries...
[0:12] <VivaPenguinos_> I hopped into python since I learned it quick.
[0:12] <nerdboy> just time both of your sensor calls
[0:13] <VivaPenguinos_> I am ok if I have a foundation to write it on. But from scratch not so well lol.
[0:13] <VivaPenguinos_> Will do
[0:13] <nerdboy> quicker than rewriting it in another language...
[0:14] <nerdboy> easy to see if it's blocking on one of them
[0:14] <gordonDrogon> Try BASIC :)
[0:14] <nerdboy> gordonDrogon: my first official programming class was basic on punch cards...
[0:14] <nerdboy> 1979...
[0:15] <nerdboy> maybe 1980
[0:15] <VivaPenguinos_> hahaha.
[0:15] * loadbang (~loadbang@host86-177-236-147.range86-177.btcentralplus.com) has joined #raspberrypi
[0:15] <VivaPenguinos_> Someone told me to write it instead of C instead of Shitty Python
[0:15] <VivaPenguinos_> His justification: Efficentcy
[0:15] <nerdboy> we never saw the computer, just the box of cards
[0:16] <kephra> nerdboy, and the printout of error messages, I guess
[0:16] <nerdboy> use the proper functions for what you're doing and it should be fast enough
[0:17] <nerdboy> kephra: on fanfold green/white paper...
[0:17] <VivaPenguinos_> The current program is grabbing 9 datapoints / min
[0:17] <bsdfox> VivaPenguinos_, pastebin the python code
[0:18] <VivaPenguinos_> Don't mock me, since I just wanted proof of concept working before optimization.
[0:18] <nerdboy> of course, actually collecting some timing data will tell you...
[0:18] <Tachyon`> didn't realise punched cards were still in use in 79/80
[0:19] <nerdboy> kephra: the next year we got to use a terminal in the chemistry lab
[0:19] <nerdboy> no display, just green/white paper and a keyboard...
[0:19] <nerdboy> that was fun...
[0:19] <VivaPenguinos_> http://pastebin.com/sh7WeV2J
[0:19] <Tachyon`> oh heh, teletype
[0:20] <nerdboy> at my jr college they were...
[0:20] <VivaPenguinos_> Yes I can see 3 ways I can optimize the coding. But my goal was to get the 2nd sensor working and have it add data into a txt file.
[0:21] <nerdboy> VivaPenguinos_: that could be your problem
[0:21] * Dyskette (~freja@cpc8-warw15-2-0-cust22.3-2.cable.virginmedia.com) Quit (Ping timeout: 256 seconds)
[0:21] <VivaPenguinos_> the redundancy I assume.
[0:21] <nerdboy> maybe it's blocking on the card write
[0:21] <nerdboy> try writing to a file in tmpfs instead
[0:21] <Phosie> I really should learn C
[0:22] * Mortvert (~Mortvert@reddit/operator/mortvert) Quit ()
[0:22] <VivaPenguinos_> so I was limited by the write speed of the SD card?
[0:22] <nerdboy> or, write a buffer to the card in a separate thread
[0:22] <bsdfox> VivaPenguinos_, I'd be very surprised if it wasn't the SD card access problem
[0:22] * NIN101 (~NIN@p5DD2AE40.dip0.t-ipconnect.de) Quit (Quit: NIN101)
[0:22] <nerdboy> try it with tmpfs and see
[0:23] <bsdfox> VivaPenguinos_, create a ramdisk and try to write there.. I bet you get the speed you want
[0:23] <VivaPenguinos_> Read speed is ~20mb/s
[0:23] <VivaPenguinos_> Write is ~10mb/s
[0:23] <bsdfox> that doesn't matter
[0:23] <bsdfox> IO/s can suck
[0:23] <SpeedEvil> small block write speed can be as low as a kilobyte a second
[0:23] <VivaPenguinos_> lemme try ramdisk
[0:23] <SpeedEvil> Worst case.
[0:23] <nerdboy> latency ...
[0:23] <SpeedEvil> And you can have over a second latency
[0:24] * nerdboy wants to see some data
[0:24] <VivaPenguinos_> Hold on
[0:24] <VivaPenguinos_> Lemme grab the data for you
[0:25] <nerdboy> it's your data... i just want to see the timings of tmpfs writes vs sdcard
[0:25] * Midnigh2ker (~Toker@unaffiliated/midnightoker) Quit (Ping timeout: 264 seconds)
[0:26] * Firehopper (~Firehoppe@pool-71-185-121-114.phlapa.east.verizon.net) has joined #raspberrypi
[0:26] <gordonDrogon> C won't neccessarily make things faster if it's the operating system that's slowing things down.
[0:26] <VivaPenguinos_> I'm learning how to create ramdisk atm.
[0:26] <gordonDrogon> having open/write/write/close inside the loop won't be fast either.
[0:26] <nerdboy> can some maybe add "try it and see..." to the topic?
[0:27] <gordonDrogon> you need to open outside the loop, then do the writes, then close when you exit the loop, if possible.
[0:27] <VivaPenguinos_> I'm more of a hardware person then software. So for me it'll take some time getting used to
[0:28] <nerdboy> exactly, put the data in a buffer and write after or periodically in another thread
[0:28] <gordonDrogon> nerdboy, no need - there are standard libraries for that - at least in C.
[0:28] <nerdboy> python
[0:28] <nerdboy> but yeah, at minimum open and close once
[0:28] <gordonDrogon> it looks like log = open('temperaturelog.txt', 'a') is just an interface to the standard IO library anyway.
[0:29] * kcj (~casey@unaffiliated/kcj) Quit (Ping timeout: 264 seconds)
[0:29] <VivaPenguinos_> it's standard IO
[0:29] <VivaPenguinos_> I have first gen Rasp-pi, So I think 10MB ram disk is enough?
[0:29] <gordonDrogon> so move the open outside the loop.
[0:29] <BCMM> nerdboy: so are there pre-existing recipes for mpd? should i just be adding that to console-image?
[0:30] <nerdboy> python has a lot of "batteries included..."
[0:30] <nerdboy> BCMM: you can do that...
[0:30] <nerdboy> or make your own recipe file and include console image
[0:31] <VivaPenguinos_> Moved it out the look and it gave error on I/O operation on closed file
[0:31] <VivaPenguinos_> while loop
[0:32] <nerdboy> open the file in write mode, loop, then close the file
[0:33] <VivaPenguinos_> Close the file outside of while:?
[0:33] <nerdboy> yes
[0:34] <gordonDrogon> not much point since the while is an infinite loop.
[0:34] <gordonDrogon> the file will be closed when you control-c.
[0:34] <nerdboy> huh?
[0:34] <ozzzy> perhaps
[0:35] <gordonDrogon> that last bit of the program was a while true thing.
[0:35] <nerdboy> maybe i should look at it...
[0:35] <VivaPenguinos_> I wanted it to write the data into .txt as it receives
[0:35] <VivaPenguinos_> Yes
[0:35] <gordonDrogon> when programs exit the always close all files (unless you do something really sneaky not to)
[0:36] <nerdboy> yeah, but i didn't expect an endless loop...
[0:36] <VivaPenguinos_> When I write .close within the loop, it updates as it gathers data.
[0:36] * Turingi (~devon@unaffiliated/devon-hillard/x-7250961) Quit (Read error: Connection reset by peer)
[0:37] * DK-MODE (~Chad_Coop@149.241.127.123) Quit (Read error: Connection reset by peer)
[0:37] * enque (~enque@ip70-160-27-9.hr.hr.cox.net) has joined #raspberrypi
[0:37] <ShorTie> gordonDrogon, would it be hard to wipe up a piThreadCancel ??
[0:37] <VivaPenguinos_> Telling Python to save it in the tmpfs I wrote
[0:38] <nerdboy> VivaPenguinos_: if you open once before the loop, you can't close it in the loop
[0:38] <nerdboy> make the loop terminate, then close
[0:38] <VivaPenguinos_> ok
[0:39] <nerdboy> it *will* be faster this way
[0:39] <nerdboy> just make it collect data for ten minutes or so
[0:40] * RaycisCharles (RaycisChar@cpc5-lutn10-2-0-cust681.9-3.cable.virginmedia.com) Quit ()
[0:40] <VivaPenguinos_> my goal is to gather temperature every 3 seconds.
[0:40] <nerdboy> 200 loops of 3 seconds
[0:40] <bsdfox> VivaPenguinos_, how much faster is it with the ramdisk?
[0:41] <VivaPenguinos_> Trying to get ramdisk working permission denied.
[0:41] <bsdfox> :P
[0:41] <VivaPenguinos_> COnfigured it with 0755
[0:41] <bsdfox> is it owned by your user?
[0:41] <nerdboy> try 1777
[0:43] <VivaPenguinos_> There we go
[0:43] <VivaPenguinos_> Now editing the Python to open it within /ram/
[0:44] <nerdboy> zram is nice for adhoc block devices
[0:44] <nerdboy> use it for swap or tmpfs
[0:45] <VivaPenguinos_> Now if I wanted to grab the data from the ram and store it in the SD card, I could make a bash script to cp from that file and store it on the SD?
[0:46] <gordonDrogon> ShorTie, no, but it would be just as easy to use the threads library directly.
[0:46] <nerdboy> VivaPenguinos_: i would use rsync, but yeah
[0:46] <VivaPenguinos_> Saving this channel on my irssi client :D
[0:47] <VivaPenguinos_> The reason why I'm doing this is this is my senior project :]
[0:47] <gordonDrogon> VivaPenguinos_, it's the close that's the killer. if you want the data on disk, that will absolutely kill performance. without the close in the loop, you need to use flush or fsync - or their python equivalents.
[0:48] <VivaPenguinos_> gordonDrogon: I'm testing the ramdisk to see if it optimized performance. I just wanted to atleast get more datapoints than just 9 / min
[0:50] <raden> is there a way to have bidirectional communications between Rpi and Arduino ?
[0:51] <mgottschlag> raden: yes... i2c, uart, spi
[0:51] <SpeedEvil> many
[0:51] <bsdfox> raden, there are lots of ways
[0:51] <ShorTie> do i need something different then pthread_cancel (blinky0) ??
[0:51] <VivaPenguinos_> By using ramdisk, I shaved it by 2 seconds.
[0:51] <raden> can it be bi-directional on i2c ?
[0:51] <ShorTie> that gives, makes integer from pointer without a cast
[0:51] <mgottschlag> i2c always can be bidirectional
[0:52] * Artpicre (~Artpicre@vit94-10-78-240-193-57.fbx.proxad.net) has joined #raspberrypi
[0:52] <VivaPenguinos_> I think I can shorten the time it takes by creating one def for reading the temperature using a loop of some kind.
[0:52] <mgottschlag> e.g. an i2c sensor can support writing (for configuration) and reading (for data)
[0:53] <bsdfox> i2c is probably going to be the toughest to implement
[0:53] <nerdboy> VivaPenguinos_: 2 seconds off what?
[0:53] <bsdfox> uart will be the easiest as it's not a master/slave protocol
[0:53] * BCMM (~BCMM@unaffiliated/bcmm) Quit (Ping timeout: 240 seconds)
[0:54] * BCMM (~BCMM@unaffiliated/bcmm) has joined #raspberrypi
[0:54] <VivaPenguinos_> the time it takes to write to the file.
[0:54] <raden> bsdfox, hmmmm
[0:54] <VivaPenguinos_> lemme write the timing first
[0:55] <nerdboy> don't do too much console i/o either...
[0:55] <gordonDrogon> raden, use serial.
[0:55] <bsdfox> raden, with i2c you have to do some arbitration stuff to send data unprompted to the master. I don't remember the specifics but I implemented it 4-5 years ago and it was a pain
[0:55] <plm> Are there problem if i use 5 usb devices on pi?
[0:55] <gordonDrogon> I've just spent the past few days writing a lot of i2c code to run in an atmega to talk to a Pi. I hateses I2C ...
[0:55] <nerdboy> save up your measurements and print out min/max/ave or something
[0:56] <VivaPenguinos_> nerdboy: eventually, I plan on removing that, for now it's for debugging soI can see
[0:56] <nerdboy> if you're timing each sensor read, etc
[0:56] <nerdboy> VivaPenguinos_: right, but a lot of console i/o can also slow it down
[0:56] <gordonDrogon> bsdfox, there are libraries, but the Pi is hyper fussy about timings.
[0:56] <raden> gordonDrogon, hmmmm
[0:56] <raden> why is I2c such a pain ?
[0:57] <gordonDrogon> raden, serial at 115200 baud is faster than i2c too.
[0:57] <raden> i hsave messed with AVR and arduino for long time I just got a PI a few days ago
[0:57] <bsdfox> VivaPenguinos_, that bit bang driver probably isn't very fast either.. if yolu really need the speed you should probably use one of the hardware peripherals on the rpi (uat/i2c/spi/usb) and use a dedicated 1-wire master chip to handle the comms
[0:57] <raden> gordonDrogon, hmmmm how many serial devices can the pi support ?
[0:57] <nerdboy> serial is definitely easiest of the alternatives...
[0:57] <gordonDrogon> raden, 1 directly or many via usb.
[0:57] * datagutt (~datagutt@unaffiliated/datagutt) Quit (Quit: Computer has gone to sleep.)
[0:58] <gordonDrogon> using usb to arduino eliminates all the level shifting stuff you might want to do too (not strictly needed for i2c, however it's sloppy not to)
[0:58] <gordonDrogon> bsdfox, Pi supports I2c natively in the kernel.
[0:59] <gordonDrogon> no need to bit-bang, etc. there.
[0:59] <bsdfox> gordonDrogon, I'm talking about 1-wire
[0:59] <bsdfox> the w1-gpio driver is bit bang
[0:59] <gordonDrogon> bsdfox, ok. yes, the 1w is. seems to work though.
[0:59] * cheasee (~cheasee@2001:858:5:2001::25) Quit (Ping timeout: 264 seconds)
[0:59] <bsdfox> gordonDrogon, yeah but it's likely to be a fair bit slower than a hardware solution
[1:00] <VivaPenguinos_> how hard would it take to edit the code in python to use I2C? since I'm not a programming Guru.
[1:00] <gordonDrogon> bsdfox, it will use more cpu cycles, but it runs at the same speed - it can't not.
[1:00] <VivaPenguinos_> and would it still beable to use several sensors using the same 3 wires
[1:01] <bsdfox> VivaPenguinos_, it'll probably take you a couple hours to convert it over
[1:01] <gordonDrogon> actually, it probably uses less cpu cycles than the effort needed to talk to an I2C type 1-W controller, but the cpu might be more idle between accesses.
[1:02] <VivaPenguinos_> time isn't an issue since I've been working on it since today noon
[1:02] <VivaPenguinos_> It's just that I don't come from a programming background so I"m learning as I go on.
[1:02] <gordonDrogon> it's always lunchtime somewhere :)
[1:02] <VivaPenguinos_> ^
[1:03] <VivaPenguinos_> 12:00 est
[1:03] <nerdboy> and it's due tomorrow...
[1:03] <VivaPenguinos_> no..... This is senior project, It last for another 12 weeks.
[1:03] <bsdfox> VivaPenguinos_, I don't think anyone can answer that question but you'll be able to find reference code online
[1:04] <bsdfox> you'll have to read some datasheets but if you're a hardware guy you should be used to that anyway
[1:05] <nerdboy> VivaPenguinos_: not an unreasonable assumption, at least with my kids...
[1:05] * AeroNotix (~xeno@abos85.neoplus.adsl.tpnet.pl) Quit (Ping timeout: 245 seconds)
[1:05] * mumixam (~m@unaffiliated/mumixam) has joined #raspberrypi
[1:05] <nerdboy> and where's your timing baseline?
[1:06] * gordonDrogon writes a little test program. brb.
[1:06] * cheasee (~cheasee@2001:858:5:2001::25) has joined #raspberrypi
[1:06] <plm> If i connect a ush hub on pi. And if I to plug 6 (six) devices (three 3g modems, 2hds and one gps), Pi will be recognize thats six devices?
[1:06] <VivaPenguinos_> Writing it as we speak lol.
[1:07] <plm> S ush/usb
[1:07] <nerdboy> VivaPenguinos_: can you paste your current version?
[1:07] <bsdfox> plm, yes. bandwdith will be limited and you'll beed a good powered hub to run it all concurrently but it should be recognized and work
[1:07] <Tachyon`> it should
[1:07] <VivaPenguinos_> which section of the timing do you want it on?
[1:07] <nerdboy> plm: as long as you don't over-power it, yes...
[1:08] <Tachyon`> yeah, would have to be a powered hub, very powred as 5 of the 6 devices are hogs
[1:08] <nerdboy> i want it all...
[1:08] <Tachyon`> the drives proabbly take more than 500mA too
[1:08] <Tachyon`> I'd say a 4A 5V supply to the hub would be needed
[1:08] <Tachyon`> for all that
[1:09] <plm> bsdfox: usb bandwidth limited? But usb is 2.0, more than 100mbps right?
[1:10] <Tachyon`> 480mbit I think but I wouldn't count on actually getting that
[1:10] <Tachyon`> as that's for all the ports and the NIC
[1:10] <bsdfox> ^^
[1:10] <plm> Ok...
[1:10] <Tachyon`> not bidirectional either
[1:10] <Tachyon`> to make things worse
[1:11] <gordonDrogon> http://unicorn.drogon.net/testFile.c
[1:11] <gordonDrogon> That runs in under a second.
[1:11] <gordonDrogon> on a Pi.
[1:11] <plm> Gordon, did you to try using pypy?
[1:11] <gordonDrogon> what's pypy?
[1:12] * nplus (~chatzilla@unaffiliated/simont) Quit (Quit: Computer dusting time..)
[1:12] * Encrypt (~Chuck-nor@AMontsouris-553-1-119-105.w92-151.abo.wanadoo.fr) Quit (Quit: Quitte)
[1:12] <plm> Is super fast python. Pypy.org
[1:12] <gordonDrogon> not interested. i don't program in python.
[1:13] <plm> Ok
[1:13] <gordonDrogon> C & BASIC for me. and a bit of PHP.
[1:13] <nerdboy> c is probably what i hack/patch the most
[1:14] <plm> I like python and c :)
[1:14] <VivaPenguinos_> If I only knew C at the level of Python lol
[1:14] <VivaPenguinos_> But then my python is bad
[1:14] <nerdboy> gordonDrogon: you might like Ada for this kind of stuff
[1:15] <nerdboy> realtime tasking model, no OS required...
[1:15] <plm> I prefer python because is faster to development
[1:15] * nerdboy likes python and Ada
[1:15] <plm> Ada is still used?
[1:15] * Artpicre (~Artpicre@vit94-10-78-240-193-57.fbx.proxad.net) Quit (Read error: Connection reset by peer)
[1:15] <plm> Where?
[1:15] <nerdboy> but i still do a lot with bash...
[1:16] <gordonDrogon> nerdboy, looked at Ada 25 years ago.
[1:16] <mgottschlag> I used ada some years ago at work
[1:16] <nerdboy> 2012 standard, so the answer must be "yes!"
[1:16] <gordonDrogon> Ada is used a lot on things like rocketry.
[1:16] <mgottschlag> a job in the area of spacecrafts, some interesting dialect
[1:16] <nerdboy> i like helpful tools
[1:16] <gordonDrogon> IT was an Ada program that crashed the Arriane 5 :)
[1:17] <nerdboy> because they took the code from another vehicle and made a porting bug
[1:17] <Tachyon`> I thouht it was an integer overflow
[1:17] <Tachyon`> as it was bigger than Ariane 4
[1:17] <Tachyon`> and someone didn't check
[1:17] <gordonDrogon> They changed the hardware without telling the software.
[1:17] <VivaPenguinos_> http://pastebin.com/FCin4e4B
[1:18] <Tachyon`> how log ago was that now
[1:18] <Tachyon`> must be over 10 years
[1:18] <nerdboy> all of the above?
[1:18] <gordonDrogon> I did some in Occam way back too. probably why I don't like pythons forced indentation.
[1:18] * tali713 (~tali713@2001:0:53aa:64c:3086:4514:b3ee:137e) has left #raspberrypi
[1:18] <mgottschlag> @langauges usedin engineering: the first time I saw a programming language which supported physical units, I was quite surprised :D
[1:18] <nerdboy> occam was for parallel stuff, no?
[1:18] <gordonDrogon> nerdboy, yup.
[1:18] <nerdboy> what hardware?
[1:18] <gordonDrogon> transputers.
[1:19] <VivaPenguinos_> I liked C because of it's {} organization
[1:19] <mgottschlag> Tachyon`: they still use Ada though, even in new projects
[1:19] <Tachyon`> ah, 1996, heh
[1:19] <nerdboy> gordonDrogon: i supported that in my computer lab in college
[1:19] <Tachyon`> C isn't particularly unusual in being organised in that way
[1:19] <VivaPenguinos_> But I'm so rustic in my C that I don't even know if I can program the raspberry pi at the level of Python
[1:19] <gordonDrogon> I worked for one of the inmos spin-offs - Meiko. We made some pretty big systems.
[1:19] <nerdboy> the guy i worked for knew one of the transputer guys and got some nubus cards on loan every spring semester
[1:20] <gordonDrogon> most of my work on the transputer was in C though (or asembler)
[1:20] <nerdboy> back then i only knew matlab and fortran
[1:20] <Tachyon`> seems we were all right re ariane 5 problem, lol, was a 16 bit integer overflow caused by ariane 4 software being used which didn't take account of the flight characteristics of the 5
[1:20] <nerdboy> but i did maintain some mpi stuff for a while
[1:20] <Tachyon`> and nobody bothered to simulate it first
[1:20] <nerdboy> making the tests work was fun...
[1:21] <Tachyon`> they simulated it afterwards and it behaved the same way

[1:22] <nerdboy> gordonDrogon: he used mac II's with transputer boards to teach parallel programming with occam
[1:22] <nerdboy> 16 transputers per card i think
[1:22] * mgottschlag (~mgottschl@reactos/tester/phoenix64) Quit (Read error: Connection reset by peer)
[1:23] <VivaPenguinos_> I wasn't born in that age yet lol
[1:23] <nerdboy> we only had 6 mac II's with one card each for the class
[1:24] <nerdboy> we also had the digitalk smalltalk release so he could teach OO
[1:24] <nerdboy> in the 80's
[1:24] <VivaPenguinos_> So, I manged to optimize the coding to the level I wanted.
[1:24] <nerdboy> roger was a bit ahead of his time
[1:25] <nerdboy> and the rest of the CS dept...
[1:25] * mgottschlag (~quassel@reactos/tester/phoenix64) has joined #raspberrypi
[1:25] <gordonDrogon> there were lots of transputer platforms. Meiko has big ones - with big (for the time!) memory.
[1:25] * nerdboy was geophysics and just worked for a CS guy as a learning experience
[1:26] <gordonDrogon> yea, lots were sold to e.g. oil companies.
[1:26] <nerdboy> and so i could have a key to the lab to work on my thesis...
[1:26] * VivaPenguinos_ is a 21 year old student trying to get his senior porject working
[1:26] <VivaPenguinos_> lol
[1:26] <nerdboy> the geo dept was computing-poor at the time...
[1:26] * ozzzy can't remember being 21
[1:27] <VivaPenguinos_> lol
[1:27] <nerdboy> of course, right after i left, the geomorphology/seds guy opened a "visualization lab"
[1:27] <VivaPenguinos_> I got it optimized to 3 seconds by removing the console I/O
[1:27] <VivaPenguinos_> nerdboy: What is your degree?
[1:28] <nerdboy> ozzzy: because you haven't got there yet?
[1:28] <nerdboy> both in geophysics
[1:28] <ozzzy> I was still in the military at that time
[1:28] <nerdboy> i was getting out of jr college...
[1:28] <VivaPenguinos_> I'm doing Networking and Telecommunication. Planning to go back and get a degree in EE
[1:29] <nerdboy> VivaPenguinos_: telecomm is mostly software these days, no?
[1:29] * Geniack (~Geniack@unaffiliated/geniack) has joined #raspberrypi
[1:29] <nerdboy> EE is always good for the discipline though
[1:29] <VivaPenguinos_> Mostly Software, Programming with CLI, But not the programming as in software development

[1:30] <nerdboy> :p
[1:30] <VivaPenguinos_> so I'm amateurish with Linux but then I haven't had a job (yet) :D
[1:30] <VivaPenguinos_> My senior project is data gathering with the raspberry pi in a datacenter
[1:31] <VivaPenguinos_> Gathering data such as Temperature, Humidity, Power consumption etc. using Open source software/hardware
[1:31] <VivaPenguinos_> So a bit of both hardware and software plus preps be slightly towards the EE degree
[1:32] <gordonDrogon> zed time for me.

[1:33] <nerdboy> VivaPenguinos_: open source is my choice for most things
[1:34] <nerdboy> VivaPenguinos_: and gentoo is an excellent way to learn about Linux and open source
[1:34] <Phosie> goodnight gordonDrogon
[1:34] <VivaPenguinos_> nerdboy: For me I come from an academic background. So I tend to like research and information free and availiable for any users who are interested in the project
[1:34] <nerdboy> one time through the install handbook will prove it to you...
[1:34] <VivaPenguinos_> I'm using ubuntu since I want simplicity for my laptop for doing school work and what now
[1:34] <nerdboy> me too
[1:34] <VivaPenguinos_> not
[1:35] <nerdboy> spent ten years teaching geography with open source
[1:35] <VivaPenguinos_> nice huge respect.
[1:35] <nerdboy> including open source textbooks...
[1:35] <VivaPenguinos_> After the senior project is completed I tend to release it open source.
[1:36] <VivaPenguinos_> If anyone want to contribute after that I Guess I"ll hop on the bandwagen
[1:36] <nerdboy> keep ubuntu on the laptop and install gentoo on some old/random/surplus hardware
[1:36] <VivaPenguinos_> if not, I'll just leave it there for anyone to use and play aroud
[1:36] <nerdboy> you can even make a gentoo card for the pi
[1:37] <nerdboy> it just takes a while to compile some things...
[1:37] <VivaPenguinos_> Removing the Console I/O gave me an error "Arritbute Error: 'List object has no attribute 'strip'"
[1:37] <Phosie> Ubuntu on the netbook, Arch on the pi.
[1:38] <nerdboy> i mostly switched to debian over ubuntu lately
[1:38] <nerdboy> easy to bootstrap whatever version you need
[1:38] <VivaPenguinos_> I do plan as a test to create Linux from scratch on the pi
[1:39] <VivaPenguinos_> as a bare minimum
[1:39] <nerdboy> and since they've added arm hardfloat support i seem to use it even more
[1:39] <nerdboy> lfs might be a little overkill,, whereas gentoo is just as flexible/optimized but with better tools
[1:40] <VivaPenguinos_> Any assitance on my error message? I assume that somehow it outputted a no on != 'yes'
[1:40] <nerdboy> but i say that as a gentoo dev since 2003
[1:40] <VivaPenguinos_> atm I'm using the raspian image lol
[1:40] <nerdboy> so i might be a little biased
[1:40] <VivaPenguinos_> Unfortunately I'm not a dev. But I am biased towards linux
[1:41] <nerdboy> imho, gentoo is the sweet-spot between DIY and point'n click
[1:42] <VivaPenguinos_> I'll try gentoo when I get a chance. atm I'm trying to figure out the error message since it does work for 3-4 mins lol

[1:50] <nerdboy> then you can do things like "ssh pi@raspberrypi -t <command>
[1:50] <VivaPenguinos_> If I comment out line 41-43 and 53-55 That error message gets removed.
[1:50] <nerdboy> and not have to type a passwd every time...
[1:51] <VivaPenguinos_> But I feel that those error message deals with the DS18B20 itself
[1:51] <VivaPenguinos_> Yea I'm setting up Rsync atm. Since the SSH is from the pi to my laptop NIC

[13:40] <steve_rox> be fun to get one without a IR filter on it
[13:41] <gordonDrogon> it can be removed...
[13:41] <steve_rox> but rpi cam's seem in short supply so i wont risk it yet
[13:41] <gordonDrogon> CPC seem to have them. Might get one just for fun.
[13:41] <ozzzy> maybe if they had a 6' cable
[13:42] <steve_rox> the night vision shots may be interesting to try
[13:42] <gordonDrogon> I think they're really aimed at the "fun" end of the market. If you want a 2m cable then use Ethernet ;-)
[13:43] <steve_rox> they seem to do really nice quality shots
[13:43] <gordonDrogon> yup. there's a lot of processing going on in the GPU though!
[13:43] <steve_rox> also it does not react well when two instances of webcam cap run at same time
[13:44] <steve_rox> the cam stops responding completely
[13:44] <steve_rox> then a reboot is needed
[13:44] <steve_rox> but if your like sudo reboot it will just hang there
[13:44] <gordonDrogon> so don't run 2 instances :)
[13:44] <steve_rox> was testing shell scripts
[13:44] <gordonDrogon> which isn't a true solution, but obivously they have a little locking issue somewhere.
[13:44] <steve_rox> just happened to collide with other

[13:45] <gordonDrogon> right. my little atmega is now behaving itself very well. pretending to be 2 separate devices over the i2c to the Pi too.
[13:45] <steve_rox> i hear if you use the actual command line for time lapse they get progressively darker
[13:46] <gordonDrogon> and it seems to keep good time. better than a second a day by the looks of it, but I'm going to have to leave it going for a week to really check.
[13:46] <gordonDrogon> oh, using their built-in seauencer?
[13:46] <gordonDrogon> *sequencer
[13:46] <steve_rox> yeah
[13:46] <gordonDrogon> probably just a variable not being cleared for each loop, I suspect.
[13:47] <gordonDrogon> trivial to do it via a bash script though.
[13:47] <steve_rox> seems you get a darker image too if you set the preview to a shorter time before it takes the shot
[13:47] <gordonDrogon> Heh.. it'srainig outside and some kids have stopped on their bikes... one with a raspberry (blue) slushie thing.
[13:48] <ozzzy> a chutney squishy?
[13:48] <steve_rox> how ironic :-P
[13:48] <steve_rox> blue flavior want :-)

[16:22] <drobban> gordonDrogon: Why are you saying that the waitForInterrupt () function is deprecated and how would you suggest to handle a situation where you are waiting for an interrupt and the only solution to not reach end of program is to throw in a infinite loop

[16:23] <gordonDrogon> drobban, use wiringPiISR instead.
[16:24] <gordonDrogon> although waitForInterrupt will probably never go away.
[16:24] * gordonDrogon refreshes his memory ...
[16:25] <drobban> gordonDrogon: I suppose that wiringPiISR doesnt wait for an interrupt before returning. so you would have to use a infinite loop to prevent program to continue to the end
[16:25] <drobban> This is just an assumption made from reading the manual.
[16:26] <gordonDrogon> right. waitForInterrupt() relies on you using the gpio command to set the pin before you run your program.
[16:26] * lempiainen (~daelus@a88-112-169-150.elisa-laajakaista.fi) has joined #raspberrypi
[16:26] * S0-2 (~sgra@gateway/tor-sasl/sgra) Quit (Quit: WeeChat 0.4.1)
[16:26] <gordonDrogon> wiringPiISR waits for an interrupt - typically you'r run that function with an infinite loop inside it.
[16:26] <drobban> aaaa I see
[16:26] <Encrypt> But it consumes less CPU!
[16:26] <gordonDrogon> er, sorry, no. wiringPiISR doesn't need a loop.
[16:26] <drobban> thanks gordonDrogon.
[16:26] <gordonDrogon> it gets called every time the interrupt triggers.
[16:27] <drobban> but wait.
[16:27] <gordonDrogon> internally, there's a little bit of code that's sitting in a loop, waiting for the interrupt to trigger, and when it does it calls your ISR code.
[16:27] <gordonDrogon> but that loop calls waitForInterrupt - which waits in a non-busy way.
[16:28] * SgrA (~sgra@gateway/tor-sasl/sgra) has joined #raspberrypi
[16:28] <gordonDrogon> I wrote the ISR code because I was gettin too many queries from people who didn't understand threads under Linux - coming from a microcontroller background, so the ISR mechanism is more familiar.
[16:29] <gordonDrogon> it sort of faked, but it is triggered by a real interrupt to the cpu.
[16:30] <drobban> okey, but have I understood you correctly. If I call wiringPiISR(), it sets up a call back and then returns to the calling function and continues until a interrupt is present and then the call back is used.
[16:31] * justsee (~justsee@unaffiliated/justsee) Quit (Ping timeout: 276 seconds)
[16:31] <drobban> or is WiringPiISR() waiting to return until a interrupt is present just like the waitforinterrupt function
[16:32] <gordonDrogon> you're right the first time - wiringPiISR sets it up and returns to the caller.

[16:32] * nils_2_ is now known as nils_2
[16:32] <gordonDrogon> then you get on with what you're doing and when the interrupt fires, your interrupt function that you specified in the wiringPiISR call is executed.
[16:32] <davor> maybe a sub-optimal way of doing it, but I just can't wait until tomorrow for my breakout board.
[16:32] <drobban> gordonDrogon: Roger :).
[16:33] <gordonDrogon> davor, I've seen worse :)
[16:33] <ShiftPlusOne> davor, Would be a shame if someone were to... pull all of those out >=)
[16:33] <gordonDrogon> drobban, have a look at the isr.c example program.
[16:34] <ShiftPlusOne> davor, instead of doing that, I cut the connector off, stripped and tinned the wires so that they could be plugged directly into the breadboard.
[16:34] <drobban> gordonDrogon: Ill do that
[16:34] <davor> luckily I remembered I have these jumper cables instead it would all just be wires gordonDrogon

[16:35] <drobban> gordonDrogon: so you use a infinite loop and use a delay to not hog up all the cpu?
[16:36] <gordonDrogon> drobban, in my code? No - it uses the poll() system call which deschedules the process.
[16:37] <gordonDrogon> drobban, my example isr.c program sits in a 100% cpu busy loop, but the interrupt threads don't.
[16:39] <gordonDrogon> drobban, if you use waitForInterrupt() or wiringPiISR() then the only CPU you'll burn is what you use yourself. These functions will use zero cpu until needed.
[16:40] <drobban> the problem i am facing is that I use a infinite loop before the end program to prevent it from reaching the end.
[16:40] <drobban> But, I feel like I am looking at situation from a bad angle.
[16:41] <gordonDrogon> setup the interrupt handlers before entering your infinite loop.

[16:43] <drobban> I am looking at your program isr.c. The scenario is. Is there a better way to do it then throw in a infinite loop in the main thread to stop the program to reach the end of program,
[16:44] <drobban> Reason to why I am asking the question, is that I assume that a infinite loop sucks a lot of CPU to no good.
[16:44] <gordonDrogon> not really. If the program is purely event driven with no real "main", then just: for(;;) delay(1000) ; and forget about it.
[16:44] * tanuva (~tanuva@p4FF634F7.dip0.t-ipconnect.de) Quit (Quit: Leaving.)
[16:44] <gordonDrogon> there isn't really a sort of sleepForever() type call.
[16:44] <drobban> aaa, so you do use the delay() to stop it from sucking alot of cpu. Is that correct?
[16:44] <gordonDrogon> yes.
[16:45] <gordonDrogon> actually, you could call sleep (MAXINT) ;
[16:45] <drobban> Thank you gordonDrogon. I do believe that i got my question answered by a professional =D
[16:46] <drobban> Learned something new today.
[16:46] <gordonDrogon> a lot depends on the application - sometimes the 'main' part might be the bit that interacts with the human - if it's that sort of program, but it could also be purely event driven.
[16:47] <gordonDrogon> I'm in the process of putting something together on an ATmega and the 'main' program does nothing more than sit on a sleep instruction in a loop.. that's effectively "wait for interrupt".

[19:30] <goldenwest> hi, I'm fairly new to rpi and I have an accelerometer with PWM outputs that I'm trying to read with GPIO pins 17, 21, 22 without success
[19:31] <gordonDrogon> you're trying to READ PWM into the Pi?
[19:31] <goldenwest> yeah, is that possible?
[19:31] <gordonDrogon> anythings possible. just doesn't make much sense.
[19:31] <goldenwest> okay, please correct my ignorance
[19:31] <goldenwest> I'd like to know the values the sensor is putting out
[19:31] <gordonDrogon> does it really output PWM?
[19:31] <SpeedEvil> In principle, you could poll it with DMA.
[19:32] <SpeedEvil> gordonDrogon: Some do.
[19:32] <murple> goldenwest probably just means it is an analog device.
[19:32] <SpeedEvil> It's an unfortunately picked device - there are any number of more suitable ones.
[19:32] <gordonDrogon> yea, integrate it then use a AtoD.

[19:48] <Dan39> guess thats what i get for going with cheap monoprice keyboard
[19:49] <Demp> it all depends on the power adapter you're using I guess
[19:50] <Dan39> im using one with a so-called "2A port" lol
[19:50] <Dan39> and a short usb cable
[19:50] <Demp> how much power is a shit ton, btw?
[19:51] <Dan39> for a keyabord... ummmm
[19:51] <Dan39> 0.5 A
[19:51] <Dan39> aka 500 mA
[19:51] <Demp> yep, that's pretty damn high
[19:52] <Dan39> yea i noticed the pi acting funny when i was using the keyboard
[19:52] <Dan39> along with it having a really long wire going to it lol
[19:52] <Dan39> well i forget if the pi did
[19:52] <Dan39> or just the keyboard
[19:52] <Demp> mine without a powered hub just misses key presses
[19:53] <Dan39> o and ya know the lenght of power cable from adapter can have big impact. using this same "2A port" power adapter i was using a longer like 5 ft usb cable and having problems
[19:53] <ShiftPlusOne> Demp, Dan39, family friendly channel, please mind the language.
[19:53] <Dan39> changing to the shorter like 3 ft and it runs great

[22:33] <markovh> i mean when software shuts it down, it auto boots back up

[22:36] <canid> you could possibly keep one of the GPIOs high and use it to trigger the reset pin if it goes low
[22:37] <Batolemaeus> no, not poe. Attach rpi to power strip via adapter, and power cycle the powerstrip if the rpi is down
[22:37] <canid> I can't remember if the reset pin is pull high or pull low, but a simple circuit could do that either way

[23:01] <SWAT> canid: thanks for trying to debug this for me. The noise is only noticeable when I listen to balads etc. (low-volume songs), so the noise level is unfortunately not related to that I think.

[23:03] <canid> The noise is almost certainly related to that. It's being picke up by something long enouch to function as an antenna, and the most likely culprit is the headphone cable. If the problem isn't there then it is likely a trace on the board. The noise is still RFI coming from somewhere, whether ambient and from one of the active devices on-board

[23:06] <Firehopper> okay for those rpi gurus, is there a way to take a small image. 28pix high by say 100-400 pix wide, and extract the image info into say a text file or maybe C code.. I want to send image data to my rgb stick for painting with light, and I dont want to have to type the data myself..

[23:07] <Firehopper> led # would be for each of the 28 rows.
[23:07] <canid> It could be. If it's on the board, then I would think it results from poor ground plane design

[23:08] <canid> minding that I am something of an idiot. I do the best I can :D
[23:08] <mgottschlag> Firehopper: of course that is possible, but you'd have to write that program yourself
[23:08] <mgottschlag> have a look at stb_image for a simple and short image loader which you can use to load the source data, then your program can output whatever you want
[23:08] <canid> somebody wrote a program for doing this with bitmaps
[23:08] <canid> was used in an msp430 project I saw
[23:08] <Firehopper> mgottschlag, what I need is something easy to write said program with, and figure out what type of image would be best for this.
[23:09] <SWAT> canid: thanks for your input, appreciate it. Don't know why I didn't think of it ;)
[23:09] <canid> I think it was called Image2Code
[23:09] <Firehopper> dont know if py or C would work. I know very little of either laguage..
[23:09] <canid> http://sourceforge.net/projects/image2code/
[23:09] <Firehopper> I'm slowly learning C :)
[23:10] <Firehopper> and I hope it would work on a RPI :)
[23:10] <Firehopper> as thats the only linux thing I have right now :)
[23:10] <canid> it just builds an array or struct of the pixel values to plug into your software
[23:10] <quackgyver> I'm trying to do a bunch of things with Py, and I'm having some issues troubleshooting my script to see if the problem is the approach itself or just some technicality like syntax errors or incorrect type conversions. The biggest problem for me is trying to figure out how to go about getting enough information out of py in each individual situation to be
[23:10] <quackgyver> able to discern anything, and I find that I'm always waiting around to get input from someone more experience. TL;DR: Would anyone in here mind mentoring me in PM for just 10 mins so I can learn how to troubleshoot a couple of quirks? :/
[23:12] <Batolemaeus> http://sng.sourceforge.net/ would this help?

[23:39] <canid> Firehopper; I'm looking into PIL right now. At a glance, it looks like it'll do just what you want in terms of getting pixel data from image files
[23:39] <canid> but; do you need to do this on the fly, or in advance?
[23:40] <canid> and are you needing RGB, mono or grayscale?
[23:40] <Firehopper> canid, from what I've read so far, PIL is abanonded..
[23:40] <canid> argh. of course it would be
[23:40] <canid> ll
[23:40] * Phosie crosses her fingers.
[23:40] <Firehopper> basicly just need to supply it a image file.. and extract the rgb values from it
[23:41] <canid> and you need to do it natively on the pi
[23:41] <Firehopper> and it would be nice if I could get it to go and output the data in the format of hex XXXXXX
[23:41] <Firehopper> where XXXXXX = GGRRBB
[23:42] <canid> should be doable
[23:42] <Firehopper> taking only the bottom 7 bits and setting the 8th bit..
