[0:04] <DanDare> When pi boots, how it gets the correct time/date ?
[0:04] <DanDare> Im used to ntpdate, but its not installed
[0:04] * cccyRegeaneWolfe is now known as cccy_RegeaneWolf
[0:04] <shiftplusone> the package is just called 'ntp', I believe
[0:05] * Aqua` (~Aqua`@82-170-38-147.ip.telfort.nl) Quit (Quit: Bye)
[0:06] <DanDare> shiftplusone, yeah, i saw that loading at boot but im not sure if its ntp server or how to configure it

[0:07] <lost_soul> DanDare: http://www.raspberrypi.org/forums/viewtopic.php?f=63&t=13313
[0:07] <DanDare> I set the correct GMT for my country bu pi still displaying wrong time, despite date is being displayed correctly
[0:07] <DanDare> thanks lost_soul
[0:08] <lost_soul> DanDare: wrong link, my bad.. sec
[0:08] <DanDare> ok :)
[0:08] <lost_soul> DanDare: use this one http://www.htpcbeginner.com/fix-openelec-incorrect-time-raspberry-pi/
[0:08] <DanDare> right, thanks
[0:08] <lost_soul> that should work even if it isn't openelec
[0:09] * kilnaar (~kilnaar@c-98-236-5-157.hsd1.pa.comcast.net) Quit (Quit: kilnaar)
[0:09] <DanDare> lost_soul, thats using ntpdate. will just install it then
[0:10] <lost_soul> DanDare: what distro are you using?
[0:10] <DanDare> lost_soul, raspbian
[0:10] <DanDare> its not installed by default
[0:10] <lost_soul> maybe it is just ntp on rasbian?
[0:10] <DanDare> bah, now im confused, its maybe installed by default
[0:10] <DanDare> i dont know
[0:11] <DanDare> i guess ntp service is server service, but not sure
[0:11] * msodrew (~msodrew@cpe-68-175-16-198.nyc.res.rr.com) has joined #raspberrypi
[0:11] <lost_soul> I would think whatever is needed for correct date and time is there... as pi has no way to keep date and time
[0:11] <DanDare> I know
[0:12] <lennard> the ntp package is usually *used* as a client, but by default also *functions* as a server
[0:13] * thomasreggi (~thomasreg@cpe-67-244-101-108.nyc.res.rr.com) Quit (Remote host closed the connection)
[0:13] * tanuva (~tanuva@HSI-KBW-046-005-002-181.hsi8.kabel-badenwuerttemberg.de) Quit (Quit: Leaving.)
[0:13] <lost_soul> well, ntpd is the server daemon
[0:13] <lost_soul> if memory serves
[0:13] <lennard> if /etc/ntp.conf has 'server X' directives, it will use those servers to get the time from, and sync the local system time to it
[0:13] <DanDare> i guess "ntp" is just some alias for stuff
[0:13] <lennard> in addition, it will also listen for time requests to provide the time... but most people don't use it
[0:13] <DanDare> lennard, so i dont need ntpdate ?
[0:14] <lennard> in debian (and thus raspbian) this is what the ntp package does (so if this makes it more clear for you, go ahead and refer to it as ntpd)
[0:14] <DanDare> just a matter of trying the usual ntp configuration i guess
[0:14] <lennard> if you have the ntp package, and /etc/ntp.conf contains server-directives, you do not need ntpdate, correct
[0:14] <DanDare> ok, thanks
[0:15] <DanDare> Its weird because i set the correct GMT for my area, pi displays the date correctly but not the time. So theres already something loading the time, but incorrectly
[0:15] * Encrypt (~Chuck-nor@AMontsouris-553-1-60-101.w92-151.abo.wanadoo.fr) Quit (Quit: Sleeping time!)
[0:17] <lost_soul> wrong timezone configured?
[0:17] * Fishy (~fishy@c-69-251-248-240.hsd1.md.comcast.net) Quit (Remote host closed the connection)
[0:17] <DanDare> lost_soul, im not sure, i just picked GMT-3 from raspi-config
[0:17] <DanDare> And GMT-3 is really my time zone
[0:17] * MrMobius (~Joey@178.sub-70-198-193.myvzw.com) Quit (Ping timeout: 264 seconds)
[0:18] * thomasreggi (~thomasreg@cpe-67-244-101-108.nyc.res.rr.com) has joined #raspberrypi
[0:18] <lost_soul> how much is it off by
[0:18] <lost_soul> just curious
[0:19] <DanDare> its 19:18 right now, pi says 01:18
[0:19] <DanDare> and date returns "GMT-3", whats correct for me
[0:19] <DanDare> i just ran ntpdate and said it updated the time, but still wrong. its a mystery
[0:20] <lost_soul> DanDare: at a root terminal try typing tzselect
[0:20] <DanDare> ok
[0:21] <DanDare> lost_soul, weird... while tzselect was configuring, it displayed the correct time upon answers i gave but after it finished i still have wrong time after doing 'date'
[0:22] * linuxstb (~linuxstb@unaffiliated/linuxstb) Quit (Quit: This computer has gone to sleep)

[0:27] * Viper-7 (~viper7@ppp121-44-217-78.lns20.syd7.internode.on.net) has joined #raspberrypi
[0:27] <ShorTie> might need a reboot
[0:28] <DanDare> lost_soul, doing like instructed on the page you show me worked, by doing "dpkg-reconfigure tzdata"
[0:28] * mike_af (~mike_af@unaffiliated/mike-af/x-5454762) Quit (Quit: Leaving...)
[0:28] <lost_soul> DanDare: nice, thanks for the update
[0:28] <DanDare> so maybe theres something wrong with raspi-config for that part
[0:29] * Mikk36 (~Mikk36@mikk36.eu) has left #raspberrypi
[0:29] <lost_soul> maybe, or perhaps a reboot as ShorTie suggested may havve done it too
[0:29] <ShorTie> you can set that in raspi-cnfig too...
[0:29] <DanDare> lost_soul, i dont think so. I tried that already
[0:29] <ShorTie> you can set that in raspi-config too...
[0:30] <lost_soul> DanDare: ah, okies
[0:30] <DanDare> ShorTie, thats the point, changing the time zone using raspi-config didnt worked for me

[0:39] * sutty is now known as sutty\away
[0:39] <DanDare> heh... I disabled ntp service at boot. After rebooting pi (and unplugged it from power), it still show me the correct time :p
[0:40] * Fishy (~fishy@pool-108-22-249-254.bltmmd.fios.verizon.net) has joined #raspberrypi
[0:40] <DanDare> maybe the capacitor, holding some power for the cpu
[0:42] * Fishy (~fishy@pool-108-22-249-254.bltmmd.fios.verizon.net) Quit (Remote host closed the connection)
[0:43] * GentileBen (~RaycisCha@cpc5-lutn10-2-0-cust681.9-3.cable.virginm.net) Quit ()
[0:43] <lost_soul> DanDare: interesting that you're trying to break the time right after fixing it.
[0:43] <lost_soul> :p
[0:43] <DanDare> lol
[0:43] <DanDare> no, just testing
[0:44] <DanDare> but yeah, youre right
[0:44] <DanDare> and now i have other subject to investigate :p
[0:44] <lost_soul> trial and error is a great way to learn, so long as you don't see any puffs of smoke coming off the circuit board in the process
[0:45] <DanDare> true... :)
[0:46] <DanDare> for now possibilities are: 1- pi is not using the ntp service to update the time; 2- that capacitor on the board holds energy capable to keep something up, for some time
[0:48] * girafe (~girafe@AGrenoble-651-1-483-126.w90-42.abo.wanadoo.fr) Quit (Quit: Leaving)
[0:48] <lost_soul> or ntp can update the time without the service running
[0:48] <DanDare> true, maybe it dont need to run as daemon, strictly
[0:49] <lost_soul> the daemon might be used for clients connecting to get their time set
[0:49] * DanDare uninstall ntp
[0:49] * lars_t_h (~lars_t_h@ Quit (Quit: Leaving)
[0:49] <DanDare> j/k
[0:49] <DanDare> Yeah
[0:49] * lars_t_h (~lars_t_h@ has joined #raspberrypi
[0:50] <DanDare> filling remaining space on sd with zeros
[0:50] <lost_soul> DanDare: to test if ntp is still being used you could rename it
[0:50] <DanDare> will compact this as my personal image
[0:50] <lost_soul> as a means of testing... easier than an uninstall
[0:50] <DanDare> lost_soul, true, will do that
[0:52] <DanDare> I bough these wifi adapters, without any antenna. Its working pretty well
[0:53] <DanDare> of course it gets some internal antenna, but its smaller than the usual USB key
[0:54] <lost_soul> hopefully you won't need to access a signal to far away
[0:54] <DanDare> yeah ...
[0:55] <DanDare> hmm, cant find whats ntp binary. its not called just 'ntp'. did a search on all filesystem, it should call something else
[0:55] <DanDare> I found 'ntpd', must be it
[0:56] <lost_soul> seems to be.. judging by the raspberrypi forum it sounds like you should have ntpd and ntpdate
[0:57] <lost_soul> but you said earlier you don't have ntpdate
[0:57] <DanDare> lost_soul, strange. Maybe i did some mistake then... thinking it wasnt installed previously
[0:58] * snuggyfoo (~ares@ has joined #raspberrypi
[0:58] <lost_soul> so long as it works, doesn't really matter I guess
[0:58] <DanDare> well it kinda matter for me (need more attention)
[0:59] <DanDare> *pay

[0:59] <DanDare> lost_soul, sure

[1:00] <DanDare> was just asking about it
[1:00] * nerdboy (~sarnold@gentoo/developer/nerdboy) Quit (Ping timeout: 272 seconds)
[1:01] <DanDare> I installed it in some other sd card, booted it, but had some problem.. i didnt worked on it really, just boot it once
[1:01] <lost_soul> ah

[1:03] <DanDare> lost_soul, for now, just using ssh, vncserver and tested by 'big' tv: http://i.imgur.com/emp4klo.jpg
[1:03] <lost_soul> lol, that is a big tv
[1:04] <lost_soul> you'll be playing 1080p videos on that in no time
[1:04] <DanDare> hahah yeah,... the little, big TV :p
[1:04] <lost_soul> :P
[1:04] <DanDare> hahah sounds funny
[1:04] <DanDare> i need try aview on it

[1:05] <lost_soul> makes me want to get a small LCD off ebay now... thanks :\
[1:05] <DanDare> i bought it used, it was so cheap that i decided i wanted it, some time ago
[1:06] <DanDare> it was cheap cause sound was broken. but it was easy to fix, fortunately
[1:06] <lost_soul> handy to have around
[1:07] <DanDare> just the lm386 part
[1:08] * utack (~utack@mnch-d9bded87.pool.mediaWays.net) Quit (Remote host closed the connection)
[1:09] <DanDare> i originally bought it, thinking to use it in some very rudimentary analog oscilloscope project... but never realized that
[1:12] <lost_soul> never to late
[1:12] <DanDare> sure
[1:20] <ShorTie> they have come way down in price, you can get a nice lcd 1 for about 4 bills
[1:21] <ShorTie> blaaa, Target "${platform}-build" does not exist in the project "Arduino".

[2:36] <SpeedEvil> (or broadcast)
[2:36] <Geo> Not part of my question, but as a network administrator, I can do what I want on it.
[2:36] <SpeedEvil> Ah
[2:36] * Macuser (~textual@unaffiliated/macuser) has joined #raspberrypi
[2:37] <SpeedEvil> Also, the pi is only 100mbps ethernet
[2:37] <SpeedEvil> As to performance - it's basically irrelevant as long as you're not trying to run firefox on it at the same time.
[2:37] <SpeedEvil> You probably don't want to run X on it.

[5:02] <DanDare> how long it takes to 'gpio write 0 1' to execute ?
[5:02] <MY123> DanDare: Do a 'time gpio write 0 1'
[5:03] <aznPIG> Don't know personally, but I'm assuming not longer than 1 sec
[5:03] <DanDare> MY123, 'time' is accurate ?
[5:04] <DanDare> cool command, i didnt knew it
[5:04] * Vutral (~ss@mirbsd/special/Vutral) Quit (Ping timeout: 256 seconds)
[5:04] <MY123> DanDare: It is accurate. The drift is 6 seconds per month.
[5:04] <DanDare> I see
[5:04] <DanDare> it says "real 0m0.015s"
[5:04] <DanDare> and "user 0m0.010s"
[5:05] <MY123> DanDare: Good, not a very high time. Take the real value.
[5:05] <DanDare> and "sys 0m0.000s"
[5:05] <MY123> DanDare: Take 'real'

[5:10] <DanDare> well, the idea of using bash + gpio for my first try doesn't sound good
[5:10] <bsch00> what are your timing requirements?
[5:11] <DanDare> i have a simple bash that just loop 'gpio write 0 1' 'gpio write 0 0' indefinitely. If i do a 'find' at command line it gets totally distorted
[5:12] <DanDare> bsch00, nvm... thinking about it now, it will not interfere on what im trying to do
[5:12] <DanDare> i just need to read a state of a button and calculate for how much it was pressed. i can just take time values from the OS instead of any bit count
[5:13] * pksato (~PEBKAC@unaffiliated/pksato) Quit (Quit: Problem Exists Between Keyboard And Chair)
[5:14] <Tachyon`> you could have an array with a characgter for each key
[5:15] <Tachyon`> when pressed, increment value, when released decrement by larger value
[5:15] <Tachyon`> you get time pressed and debounce at no extra cost
[5:15] <DanDare> time command was pretty accurate. scope says a complete ON OFF sequence with gpio is 25ms
[5:15] <DanDare> considering theres nothing more eating cpu ...
[5:15] <DanDare> Tachyon`, ok. I just need 1 button atm
[5:16] <Tachyon`> oh, lol
[5:16] <DanDare> :)
[5:16] <Tachyon`> I just recently designed a keyboard for my little computer so had to do that
[5:16] <DanDare> i regret. scope says 28ms
[5:16] <Tachyon`> http://i.imgur.com/VhfL7vw.jpg
[5:17] <DanDare> Tachyon`, oh, cool keyboard, nice keys
[5:17] <Tachyon`> aye, clear and printed, the display is temporary as I don't have a bigger one until it walks here from china
[5:17] <Tachyon`> the comptuer board is partially finsihed but can boot a basic interpreter in the internal 16K (not wired up the SPI RAMs yet)
[5:19] <DanDare> I can have more stable outputs from pins (no so cpu dependent) compiling code that uses the wiringPi library or using python ?
[5:20] <DanDare> Tachyon`, are you using pi for that?
[5:20] <Tachyon`> no, I didn't claim to be on topic
[5:20] <Tachyon`> it uses an atmega 328p for the terminal controller
[5:20] <Tachyon`> and an atmega 1284p for the actual computing
[5:20] <DanDare> i dont care about being or not in topic :p
[5:20] <DanDare> just curious
[5:20] <Tachyon`> and 1MiB of microchip SPI RAM
[5:21] <bsch00> if you want to minimize CPU usage, look into edge-triggered GPIO interrupts

[5:21] <Tachyon`> original arduino one before I started with proper hardaware
[5:21] <Tachyon`> and yes, I know that was ages ago but I don't have much time for it, lol
[5:21] <DanDare> Tachyon`, are you rebuilding a MSX of some sort? :p
[5:21] <Tachyon`> http://kupo.be/ab/abhh20140415.jpg
[5:21] <Tachyon`> sort of half and half
[5:22] <Tachyon`> actually I'll be adding 6502 emulation
[5:22] <DanDare> I see
[5:22] <Tachyon`> so it can run BBC language roms
[5:22] <DanDare> from fpga's ?
[5:22] <Tachyon`> oh no, I don't know how to use FPGAs yet
[5:22] <DanDare> me neither, actually, far from that
[5:22] <Tachyon`> although it's on the list of things to learn
[5:22] <Tachyon`> lol
[5:23] <DanDare> *.BAS reminds me of very old stuff
[5:23] <Tachyon`> http://kupo.be/ab/bastest9.jpg
[5:23] <Tachyon`> various terminal fonts and so on
[5:23] <Tachyon`> yes, I wrote a basic interpreter for it
[5:23] <DanDare> thats a cool character set
[5:24] <DanDare> the smaller you can get for something readable
[5:24] <Tachyon`> aye, I did 4x8, 6x8, 8x8
[5:24] <DanDare> But i guess you copied the character set from somewhere, right ? I mean, its very typical
[5:25] <DanDare> I remember having them on some apps on HP48
[5:25] <Tachyon`> http://kupo.be/ab/bastest8.jpg
[5:25] <Tachyon`> some of the 6x8 characters I took from my Casio FX-730P
[5:25] <Tachyon`> if I couldn't work out how to draw them well
[5:25] <DanDare> I see
[5:25] <Tachyon`> the 4x8 one is loosely based on one of the MS-DOS ones
[5:25] <Tachyon`> the 8x8 one is directly stolen from the BBC
[5:25] <Tachyon`> only 32-126 obvously, the rest I drew
[5:27] <DanDare> My plan is to add a 'halt' button on pi case
[5:27] <Tachyon`> http://kupo.be/ab/keyboard6.gif <- keyboard image you can actually see, and why yes, they did have to be printed and individually cut out, that took ages, lol
[5:27] <Tachyon`> ahh?
[5:28] <Tachyon`> that's out of date
[5:28] <DanDare> heh
[5:28] <DanDare> pretty nice keys. looks like some old terminal ones
[5:28] <Tachyon`> no, that image
[5:28] <Tachyon`> I've just had a server move
[5:28] <DanDare> with the transparent keys
[5:29] <Tachyon`> http://kupo.be/ab/keyboard6.gif
[5:29] <Tachyon`> dammit
[5:29] <Tachyon`> http://kupo.be/ab/keyboard7.gif
[5:29] <Tachyon`> lol
[5:29] <Tachyon`> that's the current one
[5:29] <Tachyon`> but yeah, they were about 10 for a pound from a chinese ebay seller
[5:30] <Tachyon`> but about half of them are too wobbly
[5:30] <Tachyon`> so you have to buy twice what's needed
[5:30] <Tachyon`> which is still really cheap
[5:30] <DanDare> damn
[5:31] * taza (~taza@unaffiliated/taza) Quit ()
[5:31] <Tachyon`> Ithat'll be the only keyboard like that though
[5:32] <Tachyon`> it's not actually that nice to type on

[5:32] <Tachyon`> need to find somewhere that can make rubber keymats for me
[5:33] <DanDare> Tachyon`, stole ones from some actual keyboard
[5:33] <Tachyon`> ?
[5:33] <Tachyon`> that wouldn't be helpful for mass production, lol
[5:33] <DanDare> The rubber contact pads right?

[5:34] <DanDare> Oh... youre making a computer for mass production.. didnt knew it
[5:34] <Tachyon`> I'll be adding compute module support to this too
[5:34] <Tachyon`> well, a modular one,there'll be a kickstarter
[5:34] <DanDare> ok
[5:34] <Tachyon`> so you can just use the CPU basic stamp style or have one of two full machines (calculator and old computer form factors)
[5:34] <Tachyon`> I'll be open sourcing the code anyway
[5:35] <Tachyon`> but perhaps not the hardware designs although china will likely shaft me either way if it does any good
[5:35] <Tachyon`> but for robotics and so on
[5:35] <Tachyon`> it supports up to 160 I/O lines althoguh you can't see that in the pics

[5:38] <Tachyon`> the calculator style one should be doable for under 30 quid,I dunno yet, it depends if there's any interest and how much if there is, heh

[7:30] <RahulAN> I am logged on a Display and also on one machine by ssh. i want to access that display i mean to move it mouse.
[7:31] <RahulAN> or opening any aap from here (ssh ) and it must run over the display?
[7:32] <DanDare> RahulAN, sorry, i think i dont got it. What you did? Did 'startx' or similar from the ssh session ?
[7:33] <DanDare> When you do like this on normal linux distro (at least debian), it doest open the display because its just a ssh session. On pi by the other side, doing so will open X on video output. I think its some modification they did on the system
[7:35] <DanDare> Anyway, i think its possible to start a X session from ssh on any linux, but it will require esxtra code on the command line. pi just do it from the regular startx

[8:59] * AlanYue (~AlanYue@ Quit (Ping timeout: 255 seconds)
[8:59] <gordonDrogon> no idea.
[8:59] <msodrew> you can’t check?
[8:59] <gordonDrogon> why would I sudo su when I can just su ?
[8:59] <msodrew> you mean why would I sudo su when I can just sudo* ??
[9:00] <gordonDrogon> the issue is usually cron jobs or rc.local scripts - they're run with a very minimal $PATH - using su or logging in as root will run roots .bashrc, etc.
[9:00] <msodrew> yeah dude i know
[9:00] <gordonDrogon> no - I use su as I set a root password.
[9:00] <msodrew> thats why im asking you
[9:00] <msodrew> to become root
[9:00] <msodrew> via $ sudo su
[9:00] * Alina-malina (Alina-mali@unaffiliated/alina-malina) has joined #raspberrypi

[9:00] <gordonDrogon> root@pi0:/etc/apt/sources.list.d# which gpio
[9:00] <gordonDrogon> /usr/local/bin/gpio
[9:01] <gordonDrogon> sudo su will inherit my existing $PATH.
[9:02] <msodrew> whoops, i meant sudo su - root
[9:03] <gordonDrogon> root still has /usr/local/bin/ in its path
[9:03] <msodrew> so you’ve logged what $PATH is in rc.local?
[9:04] <msodrew> like
[9:04] <gordonDrogon> root@pi0:~# fgrep PATH /etc/profile
[9:04] <gordonDrogon> PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
[9:04] <gordonDrogon> PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games"
[9:04] <gordonDrogon> export PATH
[9:04] <msodrew> echo $PATH >> /home/pi/path-on-boot.log
[9:04] <gordonDrogon> /etc/profile is sourced into an interactive bash.
[9:05] <gordonDrogon> and if I did your command above it would fail as I don't have a user 'pi' on my Pi's.
[9:05] <msodrew> well its irrelevant.. we’re trying to debug here. it could be
[9:05] <msodrew> echo $PATH >> /root/path-on-boot.log
[9:05] <msodrew> why dont you just call it with its absolute path if its in a startup script?
[9:06] <gordonDrogon> there is nothing to debug - the issue is simply that there is no $PATH set at boot time (for /etc/rc.*/ ) and for cron jobs the $PATH is set explicity in the /etc/crontab
[9:06] <msodrew> /usr/local/bin/gpio arg1 arg2 arg3

[9:07] <gordonDrogon> I have no problems with running gpio. as it's author, I know exactly how it works and where it lives.
[9:08] <msodrew> ok
[9:08] <gordonDrogon> I also know how Linux works at boot time - how the /etc/rc.* scripts work and how cron works too.
[9:08] <msodrew> ok
[9:08] * DanDare listen
[9:08] <gordonDrogon> DanDare was having issues and (I suspect) just emailled me (however I get these emails on a weekly basis)
[9:09] <DanDare> Hello Gordon, I didnt emailed you
[9:09] <gordonDrogon> the usual issue is eithe running from an rc script where there is no path setup or from cron which may not have the path either. (or some othe environment - some web cgi scripts, maybe - I don't know what people do with their Pi's!)
[9:09] <gordonDrogon> DanDare, Ah, your back - jus a coincidence then :)

[9:18] <msodrew> I have 2 raspberry pi’s. One of them is running hsairport and both are indepently connected to a single speaker.
[9:19] <msodrew> What’s the best approach to mirroring the sound wirelessly to the slave raspberry pi (not running shairport)?

[11:29] <gordonDrogon> right. now to move it to a suitable place for the camera
[11:29] <shiftplusone> vcgencmd version ?
[11:29] <gordonDrogon> Jul 23 2014 21:12:29
[11:30] <shiftplusone> excellent
[11:30] <gordonDrogon> so what command to take a photo? (bear in-mind, I'm ssh'd into it)
[11:30] <shiftplusone> I suppose raspistill -o test.png should do it
[11:31] <gordonDrogon> hm. tells me camera is not enabled. it was, but I'l run raspi-config again.
[11:31] <shiftplusone> do you have start_x=1 in config.txt?
[11:31] <gordonDrogon> unlikely
[11:31] <gordonDrogon> just rebooting after enabling camera.

[11:33] <shiftplusone> but it works =)
[11:33] <shiftplusone> and nice laser printer, 'course
[11:33] <lost_soul> P3n7u5: have you tried openelec? Might be worth a shot if you haven't
[11:34] <gordonDrogon> yes, it worked OK.
[11:34] <gordonDrogon> it took a few seconds to take the picture, but I guess that's to be expected.
[11:34] <shiftplusone> this thread made me wonder if I broke anything http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=82744
[11:35] <shiftplusone> which I may have, but the guy who jumped in towards the end of the thread hasn't provided all the information I asked and I don't want to ask multiple times
[11:35] <P3n7u5> lost_soul: Nope I am using raspbian, and it should stay like this because of the requirement of the task
[11:36] <lost_soul> P3n7u5: okies
[11:36] <P3n7u5> I awant to read a from a PN532 NFC reader using python
[11:36] <P3n7u5> want*

[11:37] <P3n7u5> we use it for an attendance system
[11:37] <P3n7u5> lost_soul: Any idea would be gladly welcome
[11:37] * gordonDrogon wonders what's wrong with just calling out the register ...

[11:39] <gordonDrogon> shiftplusone, still need a test on a B+?
[11:39] <shiftplusone> If it wouldn't be too much hassle
[11:40] <gordonDrogon> ok - it'll take me a few mins to dismantle the Pibow cases they're in & move the camera.
[11:40] <shiftplusone> I've tested it here in every way I could, so it 'should' be fine, but if it doesn't work for one guy with this firmware, but works with older firmware... it's a bit of a problem.
[11:40] <lost_soul> P3n7u5: I thought your main concern was using it as a media center based on xbmc and capable of watching television too. Openelec is great for these tasks. It does have a limited python package installed that may do what you need, then again it may not and could require you to install the normal python package.
[11:41] <shiftplusone> But again, I'd need him to provide all the info to rule out pebcak errors
[11:41] <gordonDrogon> yea :)

[13:23] <therion23> i glued a set of heatsinks into my pi yesterday, and now, if i as much as touch the one closest to the USB ports, they reset .. any idea what causes that?
[13:23] * pksato (~PEBKAC@unaffiliated/pksato) has joined #raspberrypi
[13:24] <shiftplusone> heatsinks are not supported or encourages in any way
[13:24] <shiftplusone> *encouraged
[13:24] <nid0> sounds like you shorted something
[13:24] <nid0> 1) why did you put heatsinks on 2) you say "glued", I hope for your sake you mean you used proper thermal paste 3) get rid of them, they're pointless
[13:24] <therion23> absolutely nothing is shorted, the sink is not touching anything apart from the chip surface
[13:25] <ryanteck> A heatsink on a Pi is still very much overkill
[13:25] <therion23> and yes, thermal of course
[13:25] <shiftplusone> ryanteck, overkill implies it has any effect
[13:26] <shiftplusone> just plain pointless rather than overkill
[13:26] <mgottschlag> therion23: did some of the thermal paste drop onto the PCB next to the chip?
[13:26] <therion23> nopes, none whatsoever .. and as said, the pi runs fine as long as i do not make finger contact with the sink
[13:27] <mgottschlag> thermal paste usually is conductive and you can short traces with it (or with your finger on the heatsink, which might be directly connected to the pcb through the paste
[13:27] <therion23> i dont even have to press it, even the lightest touch causes the USB ports to reset
[13:27] <nid0> therion23: exactly - you seem to be assuming that this means there isnt a short, it actually means the exact opposite
[13:28] <mgottschlag> there might be other reasons (mechanical damage, and if you press the chip down, something changes), but that sounds more unlikely to me
[13:28] * CodePulsar (~code@unaffiliated/shiningthrough) has joined #raspberrypi
[13:28] <ryanteck> What base is the thermal compound your using?
[13:30] <therion23> now that is a good question, they did it at the store i bought them at (which is a 30+ years old hobby electronics store so not your average desk clerks)
[13:31] <mgottschlag> many thermal compounds contain metal powder as the main heat conducting element
[13:31] <ShorTie> i'd take it back
[13:32] <nid0> did you ask them to heatsink your pi, or did they suggest it'd be a good idea?
[13:32] <SpeedEvil> Thermal compounds containing metal are usually not conductive
[13:32] <therion23> it was my idea, i read a few places it was a good idea and with the heatwave we have here these days i thought yeah lets do it
[13:32] <ryanteck> A lot of companies suggest heat-sinks. Purely for making money, 3 Small bits of copper sold for £5 normally.
[13:33] <SpeedEvil> Any non-metallic thermal compound is not conductive
[13:33] <SpeedEvil> And using a heatsink on the Pi is silly - the chips are not designed to lose heat from the top

[13:34] <SpeedEvil> One whole pound.
[13:34] <therion23> i see i should have asked you guys two days ago instead haha
[13:34] <ryanteck> Yeah, its not actually the CPU your cooling but the RAM which is packaged ontop of the CPU / Videocore
[13:38] <therion23> here comes the weird part: if i press it with a piece of toilet paper, nothing happens
[13:38] <therion23> its skin contact that resets it
[13:39] <gordonDrogon> why don't you remove it, then try touching the chip with it on?
[13:40] <therion23> it doesnt seem to want to come off without a fight
[13:40] <gordonDrogon> then look at this cool Pi case: http://unicorn.drogon.net/IMG_20140714_144229.jpg with a board on-top of the plastic on-top of the Pi that allows virtually no air-flow - then wonder if those dudes would have produced such a case if the Pi actually needed a heatsink...

[14:57] * dunz0r has decided that his office needs a network connected temperature monitor
[14:58] <SpeedEvil> dunz0r: https://en.wikipedia.org/wiki/Galileo_thermometer
[14:58] <SpeedEvil> Put a pi inside each, with a pressure meter to measure depth, connected via a mesh network
[14:58] <gordonDrogon> pepijndevos_, A B+ can provide power for 2 B's.
[14:59] <gordonDrogon> given a 2A PSU.
[14:59] <SpeedEvil> they work out between them what the high and low groups are, and the actual temperature reading, and then beroadcast to the network
[14:59] <dunz0r> SpeedEvil: Or DS18B20 on an I²C-network, which is the plan right now.
[14:59] <gordonDrogon> pepijndevos_, see the photo on: https://projects.drogon.net/testing-setting-the-usb-current-limiter-on-the-raspberry-pi-b/
[14:59] <SpeedEvil> dunz0r: but that's boring
[14:59] <therion23> what is a cheap and easy way of getting more digital i/o ports on a model B?
[14:59] <dunz0r> SpeedEvil: You are very correct. :)
[14:59] <SpeedEvil> dunz0r: Also, DS18b20 on a i2c network may not work very well
[15:00] <dunz0r> therion23: I²C IO-expander.
[15:00] <gordonDrogon> therion23, mvp23s17 (SPI) or mcp23017 (I2C) or 74x595 shift registers...
[15:00] <SpeedEvil> therion23: for what?
[15:00] <dunz0r> SpeedEvil: Sure it will, it's what it's meant for...
[15:00] <dunz0r> Oh wait
[15:00] <SpeedEvil> dunz0r: ds18b20 is not I2C
[15:00] <therion23> nothing more complex than driving a lot of LEDs
[15:00] <dunz0r> SpeedEvil: I meant 1-wire :D
[15:00] <therion23> individually
[15:00] <dunz0r> therion23: You could connect the LEDs in a matrix.
[15:01] <therion23> dunz, as in whateverhisname-chaining?
[15:01] <dunz0r> therion23: Or just a regular matrix, actually.
[15:01] <dunz0r> With columns and rows.
[15:01] <dunz0r> RowX+ColY lights up LED XY
[15:02] <dunz0r> therion23: Or whateverhisname-ischaining, yeah :)
[15:02] <therion23> ah, of course .. so 4x4 LEDs with 8 pins?
[15:02] <SpeedEvil> therion23: yes
[15:02] <SpeedEvil> But you can't use the pins directly unless you want very dim red LEDs
[15:03] <therion23> i swear if it wasnt so warm here i would have thought of that
[15:03] <dunz0r> therion23: Yep. Or 6x6 for 36, 10x2 for 20 etc etc
[15:03] <dunz0r> 10x2 is a bit stupid though, but you know what I mean.
[15:05] * IT_Sean (~sean@applefritter/IRCStaff) has joined #raspberrypi
[15:05] <therion23> the 4x4 is a perfect solution, that is eight two-color LEDs and that is sufficient

[15:34] <therion23> dunz0r, my Swedish supplier has the 23017 .. all i can get locally though is the pcf8574a and that only has 8 ports ..
[15:36] <gordonDrogon> therion23, they work ok, but only 8 bits as you say.
[15:36] <gordonDrogon> therion23, if you just want outputs, then you can cascade 74x595 shift registers.
[15:36] <therion23> gord, yeah, and at three times the price of the 23017 ..
[15:37] <gordonDrogon> the pcf8574 chips?
[15:37] <therion23> yep
[15:37] <gordonDrogon> that surprises me, given their somewhat crude internals ...
[15:38] <therion23> the local store here is pretty expensive because they are the only one within 40km or so
[15:38] <gordonDrogon> make sure you con't confuse the 23017 (I2C) with the 23s17 (SPI), although both work OK on the Pi.
[15:39] <gordonDrogon> therion23, yea, I live about the same distance from 2 Maplin shops - each way - I mail order most stuff from Farnell.
[15:39] <therion23> the data sheet i saw on the 23017 said it has 23s17 capabilities

[18:41] <snuggyfoo> I'm trying to mount a samba share (NAS share from dd-wrt router). Using "mount -t cifs -o username=<user>,password=<pass> // /mnt/NAS I get mount error(6): No such device or address
[18:42] <snuggyfoo> I have // /mnt/NAS/ cifs username=<user>,password=<pass> 0 0 in my fstab
[18:42] <snuggyfoo> Anyone know why I am getting said error?
[18:47] <therion23> your fstab lacks a sharename at least
[18:48] <snuggyfoo> I just got it to mount
[18:48] <snuggyfoo> I had to change it to // drive
[18:48] <snuggyfoo> thanks
[18:49] <steve_rox> heh drives me mad figureing out the syntax for that
[18:50] <therion23> i sometimes get "mount error(5): Input/output error" first time i try to mount a CIFS drive but when i repeat the command it works fine

[18:52] * Rogier (~Adium@53574CA4.cm-6-8b.dynamic.ziggo.nl) has joined #raspberrypi
[18:53] <therion23> bsch00: it happens so rarely that i cannot recreate it
[18:55] <bsch00> that's frustrating. smbclient might be useful too: smbclient -U username //hostname/share , just to see if it gives a more descriptive error
[18:56] <therion23> i think the issue is that cups isnt installed on the samba server and smbd bums out when it cannot get a printer list
[18:57] <bsch00> in that case, you can try adding load printers = no to smb.conf
[18:57] <therion23> i have tried to disable all printer support but smbd doesnt seem to care
[18:57] <therion23> it is already set that way
[18:57] <therion23> has been for three years and several generations of samba
[18:58] <therion23> it sincerely ignores me :)
[18:58] <bsch00> I also have show add printer wizard = no; printcap name = /dev/null ; disable spoolss = yes, for what it's worth
[19:02] <therion23> ooh i found a solution
[19:02] <therion23> "load printers = no", "printing = bsd" and "printcap name = /dev/null"
[19:03] <bsch00> good stuff. half the elements in my conf are probably cargo-cult nonsense, the trick is finding out which half that is
[19:03] <therion23> .. and still i/o error on first attempt, mounts fine when repeated
[19:04] <therion23> but no more cups errors at least, that is a good start

[21:35] <gordonDrogon> therion23, isn't a Linux server running samba fast enough for Win PCs?
[21:35] <therion23> gordon, not when i get ~50mbit throughput on a 100mbit full duplex connection
[21:36] <gordonDrogon> wonder where the bottleneck is.
[21:36] <gordonDrogon> one of my clients has 3 Linux servers on a 3-segment Gb LAN with about 100 client PCs connected to it - most PCs running win, but some run Linux - the win ones use Samba the Linux ones NFS.
[21:37] <gordonDrogon> they've not complained about speed, but then I don't know if they're actually benchmarked it...
[21:37] <therion23> i just did a speed test between a pi and a netbook running debian, nfs was 30% faster than cifs

[21:39] <nid0> you should generally see almost no real difference between nfsv3 and 4, there's little performance difference between the two

[21:44] <gordonDrogon> therion23, I've not actually tried a Pi as a server..
[21:44] <nid0> yes, you'll need to present an entire partition
[21:44] <gordonDrogon> I would expect NFS to be faster anyway though, regardless of the platform.
[21:46] <therion23> gordon, i used the pi as client when timing .. it will only be used as nfs client anyway
[21:47] <koell> nfs is linux only i guess, right?
[21:47] <therion23> nfs is for nearly all platforms

[21:49] <therion23> although searching for "nfs" on the Play store is borderline stupidity because of a certain popular game with the same initials :)

[22:39] <rdbell> Figured out a solution. Had to remove lines 64-68 in picamera’s camera.py and replace them with GPIO = None. This skips attempts at accessing GPIO from within the picamera module, which isn’t necessary for taking photos anyway. Attempting to access GPIO without root privileges was throwing an exception, and for some reason the exception wasn’t being caught by the try/except statement. It was just causing the script to
[22:39] <rdbell> terminate. This behavior wasn’t ocurring before. It might have something to do with the version of Python I’m running.

[23:29] <DanDare> Hi. I didn't tested here my power supply capabilities or how much current pi is using but maybe some of you guys can point me to the right direction: I get hard resets on pi by inserting a second wifi adapter. Someone told in this channel thats a common problem of the B model.
[23:30] <DanDare> This problem is related just with the pi itsefl? I mean if I use a very capable and clean power supply (lets say 3A), these problems still occurs ?
[23:30] <ShorTie> nop
[23:30] <steve_rox> yea theres a power flaw issue in rev2
[23:30] <steve_rox> rev1 not effected
[23:31] <ShorTie> there is a 700ma poly fuse on the input
[23:31] <geordie> DanDare: brown out
[23:31] <DanDare> steve_rox, do you think I can minimize this issue by adding capacitors in parallel to the USB power rails ?
[23:31] <Encrypt> Oh, now that I'm thinking about it...
[23:31] <steve_rox> i tryed something like that but dident work
[23:31] <DanDare> :(
[23:31] <steve_rox> there is a solder mod you can do
[23:31] <steve_rox> but i dont have it to hand
[23:31] <Encrypt> Has anybody had a look at the ethernet controller datasheet?
[23:31] <DanDare> ok
[23:31] <geordie> i worked around it by not doing that
[23:32] <Encrypt> Apparently, there are 3 suspend modes
[23:32] <ShorTie> the only real solution is a powered hub

[23:32] <geordie> DanDare: i just avoid hotplugging the wifi adapter
[23:32] <DanDare> fair enough
[23:33] <ShorTie> or break the power wire out of the usb connector
[23:33] <DanDare> steve_rox, anyway, i will try adding really big caps there, just for testing and see what happens
[23:34] <steve_rox> might work
[23:34] <steve_rox> good luck
[23:34] <DanDare> well, really big can lead to other issues while on initial charge
[23:34] <Encrypt> Do you think we could possible wake the pi on lan?
[23:34] <steve_rox> not really
[23:35] <DanDare> or limit the max current out from the USB ports by adding resistors
[23:35] <steve_rox> they used to have polyfuzes
[23:36] <DanDare> well, poor pi. I see already it will enter the surgery block later or sooner

[23:39] <steve_rox> when i was soldering the pad it came clean off
[23:39] <Encrypt> It would be better if everything is OK
[23:39] <DanDare> Encrypt, yeah, saw those already, pretty cool ones
[23:39] <steve_rox> electronically its sound apart from the reader
[23:39] <Encrypt> Nothing's better than an industrial soldered pad :D
[23:39] <DanDare> Encrypt, but the low profile is problematic if using a case I suppose
[23:40] <Encrypt> Yes, I imagine :p
[23:40] <Encrypt> But you have to choose x)
[23:40] <DanDare> :(
[23:40] <DanDare> yeah
[23:40] <DanDare> for the "non-intrusive" stuff, i added a halt/reboot button: http://i.imgur.com/ozAcWXB.jpg
[23:41] <DanDare> it looks cute? :p
[23:42] <DanDare> the funny fact: the button itself is twice or maybe even more bigger than the own cpu :p
[23:43] <steve_rox> not sure where the reset pins are on rpi B+
[23:43] <DanDare> steve_rox, the B+ got a dedicated reset pin/button ?
[23:45] <steve_rox> well the rpi rev2 had a physical reset pins
[23:45] <steve_rox> i assume the B+ will have some
[23:46] <DanDare> hmm, i think i will try to attach the mini sd holder on the RCA plug body, accessible from the top
[23:46] <shiftplusone> I've been using the reset on the jtag connector, but that's probably not very convenient
[23:46] <DanDare> steve_rox, oh, i got the rev2, but im not aware of any reset pin, must check that
[23:46] <shiftplusone> I'm sure there's are pins for the purpose, I just don't know where they are off the top of my head
[23:47] <Encrypt> And what do you think about my wake on lan idea?
[23:47] <Encrypt> The broadcom chip can apparently do so
[23:47] <DanDare> also, a good reset should gracefully restart the OS, not just the gross hard reset imo
[23:47] <Encrypt> s/broadcom/ethernet
[23:47] <Encrypt> But it has to enter suspend mode 0
[23:48] <Encrypt> And I haven't understood how this is managed
[23:48] <DanDare> Encrypt, you got the B+ ?
[23:48] <Encrypt> Nope
[23:48] <Encrypt> B
[23:49] <DanDare> Encrypt, you will need some external switches to switch the boar ON then, regardless
[23:50] <Encrypt> DanDare, The chip could drive a transistor to reset teh broadcom chip...
[23:50] <DanDare> for what I know, wake on lan works from special, magic packets
[23:50] <Encrypt> That was my idea...
[23:50] <Encrypt> But I don't know if it's doable
[23:53] <steve_rox> the lan card has to be awake and listening on network
[23:53] <steve_rox> if you get what i mean
[23:53] <steve_rox> not exactly a atx power supply it has
[23:53] <DanDare> Encrypt, this looks cool: http://www.rototron.info/WOL/WOL.php
[23:54] <DanDare> though i have no idea if it can be done solely with own pi hardware set, in a simpler manner

[23:57] <Encrypt> DanDare, Well, my idea is different
[23:58] <DanDare> ok
