[0:32] * linuxstb (~linuxstb@unaffiliated/linuxstb) Quit (Quit: This computer has gone to sleep)
[0:33] <FergyA> clever: so digi agrees that its a serial problem on the pi
[0:33] <FergyA> and they suspect the serial clock isnt quite cutting it, like you said :/ soooo, now I get to have some fun
[0:35] * Spiffy (~Spiffy@unaffiliated/spiffy) Quit (Read error: Connection reset by peer)
[0:35] * Mr_P (~gerhard@chello080108255018.3.14.vie.surfer.at) has joined #raspberrypi
[0:37] <home> I need a minimal image for rpi
[0:37] <home> whats the most minimal image out there?
[0:38] * owen_ (~owen@180.200.179.185) has joined #raspberrypi
[0:38] <ShiftPlusOne> Most minimal? Probably mogwai's linux from scratch image.
[0:38] <ShiftPlusOne> http://www.intestinate.com/pilfs/
[0:39] <ShiftPlusOne> Or something you'd roll yourself with buildroot and just using busybox and uclibc.
[0:40] <clever> FergyA: i know that AVR chips set the baud with a clock divisor
[0:41] <clever> FergyA: main clock / X == cycles per bit
[0:41] * pecorade (~pecorade@host62-161-dynamic.32-79-r.retail.telecomitalia.it) Quit (Read error: Connection reset by peer)
[0:41] <clever> FergyA: assuming the pi does the same thing, and you have a scope to calibrate, you can fine-tune things to get the right baud rate, with a sucky crystal
[0:41] <clever> assuming the crystal is 'stable' and doesnt change after you cal it
[0:41] * XenGi is now known as XenGi_
[0:41] <FergyA> yeah, we'll see, a lot of this is way over my head anyhow ^^
[0:42] <FergyA> I'm a MechE major :P not EE :P
[0:42] <clever> but i have no idea how to set the divisor manualy on a pi, or if its even cabable
[0:42] <clever> could ask on the forums maybe
[0:42] <clever> that also explains why i'm getting the ocasional corrupt byte in my serial console, at 115200
[0:43] <clever> hmmm, i do have a scope, so i could measure how inaccurate mine is
[0:43] * Hydra (~Hydra@AGrenoble-651-1-490-104.w90-42.abo.wanadoo.fr) Quit (Quit: HydraIRC -> http://www.hydrairc.com <- The alternative IRC client)
[0:43] <clever> 27 19:39:38 <@clever_> 1 / ((1 / 1000 / 1000)*8) == 125,000
[0:44] <clever> FergyA: left over math from when i was working out baud rate, from the scope
[0:44] <FergyA> well, I may just end up going with 9600bps and work on compressing my data as much as possible, I have a week to figure this out
[0:44] <clever> if i remember correctly, i was getting roughly 8uS per bit, but the scope wasnt zoomed in enough
[0:44] <clever> so the math was off
[0:44] <clever> try each baud rate, and see how much damage each one gives
[0:45] <clever> and pick the fastest one that has a reasonable loss
[0:45] <FergyA> yeah, 19200 works, it only fails a CRC every few minutes instead of every few seonds
[0:45] <clever> and one step down from that should be much better
[0:45] <clever> its the same thing dialup modems do, test things at every baud rate, and pick the best one the line can handle
[0:45] <FergyA> one step down from that is 9600 ^^
[0:46] * xyzodiac (~xyzodiac@97.103.247.166) Quit (Quit: Computer has gone to sleep.)
[0:46] <clever> oh, lol
[0:46] <clever> hmmm
[0:47] * jankyhellface (~jankyhell@199.193.119.32) has joined #raspberrypi
[0:48] * Turingi (~devon@unaffiliated/devon-hillard/x-7250961) Quit (Ping timeout: 240 seconds)
[0:48] <clever> FergyA: one min
[0:50] * xyzodiac (~xyzodiac@97.103.247.166) has joined #raspberrypi
[0:51] <clever> FergyA: https://github.com/raspberrypi/linux/blob/rpi-3.6.y/drivers/tty/serial/amba-pl011.c
[0:51] <clever> FergyA: line 1514
[0:51] * violet-rpi (~quassel@78-22-180-177.access.telenet.be) Quit (Read error: Connection reset by peer)
[0:51] <clever> not sure what you can do with it just yet though
[0:51] <FergyA> yeah
[0:52] <FergyA> and we'd have to know what to set it to ^^
[0:52] <clever> just a guess, can you try a non-standard baud rate?, 18000, 17000, 16000?
[0:52] <clever> you would have to configure the xbee similarly, its in the datasheet
[0:52] <clever> and may want to look up how to recover it from a bad baud (hold one of the pins to gnd i think, while its connected to the windows software)
[0:52] <FergyA> yeah, ive seen the stuff for that, that itself is hit or miss though
[0:53] <clever> using non-standard bauds, you can go faster then 9600, while keeping error rates low
[0:53] <FergyA> ive got plenty of experience with that from the 2 xbees i bricked previously ^^
[0:53] <home> what images are you guys using?
[0:53] <clever> and if you use a scope (or try randomly), you can set one to 18000 and the other to 18100, and get an error free link
[0:53] <home> FergyA, a mech major, ew
[0:53] <clever> if the baud was off by 100, for example
[0:54] <FergyA> :P I'm actually an applied physics major, that better?
[0:54] <home> urgh, yes :D
[0:54] * Syliss (~Home@108.210.164.23) has joined #raspberrypi
[0:54] <clever> FergyA: hmmm, set the xbee to 19200, then brute-force the pi, 15000 thru 20000, in 100 baud steps
[0:54] <FergyA> needest to say i am way out of my league
[0:54] <clever> FergyA: see which baud gives the best performance
[0:54] <FergyA> sounds like a plan, i will try that
[0:54] <clever> repeat at higher speeds
[0:55] <clever> but minicom may need some coersion to use non-standard rates
[0:55] <FergyA> yeah, if need be i can try screen
[0:55] <FergyA> im pretty sure its not as picky
[0:55] <clever> stty can also be used to change the default
[0:55] <FergyA> i only went with minicom because of the zmodem stuff
[0:55] * XenGi_ is now known as XenGi
[0:55] <clever> stty < /dev/ttyAMA0 18000
[0:56] <clever> echo test > /dev/ttyAMA0
[0:56] <clever> the 1st changes the 'default', effecting any future open of the device (ugly, but simple)
[0:56] <clever> the 2nd re-opens it and sends test
[0:56] * MAssEy (~msy135@ti0018a380-dhcp4218.bb.online.no) has joined #raspberrypi
[0:56] * dj_pi (~dj@c-107-5-25-243.hsd1.mi.comcast.net) has joined #raspberrypi
[0:57] * xyzodiac (~xyzodiac@97.103.247.166) Quit (Quit: Computer has gone to sleep.)
[0:58] <FergyA> so umm yeah
[0:58] <clever> http://www.raspberrypi.org/phpBB3/viewtopic.php?t=33011&p=283782
[0:58] <clever> hmmm, you can give a baud on the cli, i wonder what it will do at non-standard ones
[0:58] <FergyA> if i jumpered gpio 14 (TXD) and gpio 15 (RXD) i should get a loopback on my serial monitor no?
[0:58] <clever> yeah, but the pi will be receiving with the same offset as the transmit
[0:59] <clever> so it will always be a perfect link
[0:59] <clever> you should do that, at the far end, the other xbee
[0:59] <FergyA> and if i get nothing back?
[0:59] <clever> then try another baud rate
[0:59] <clever> brute force till you find one that works, near 19200
[1:00] <clever> thats about all you can do without a scope to verify things
[1:00] <FergyA> I dont even get anything back at 9600 :/
[1:00] <clever> what is the xbee set to?
[1:01] <FergyA> the xbee isnt even hooked up right now
[1:01] <FergyA> im simply looping back the pis serial port to try and debug in
[1:01] <FergyA> it*
[1:01] <clever> looking at it with what?
[1:01] <FergyA> looking at it with screen
[1:01] <clever> ah, not sure how that effects things
[1:02] <FergyA> and minicom does the same
[1:02] <clever> try minicom with a non-standard rate maybe, 'minicom -b 9650 -o -D /dev/ttyAMA0' and just connect tx to rx
[1:03] <FergyA> unless the serial on this thing is asyncronous
[1:03] <FergyA> which would be a bit odd...

[1:05] * datagutt (~datagutt@unaffiliated/datagutt) Quit (Quit: kthxbai)

[5:35] <NetBat> greetings Pi pickers.
[5:35] <pksato> for boot time, yes.
[5:35] <mfletcher> reason for asking, is I haven't had much luck using class 10 cards on my raspi, but class 4 is fine
[5:35] <techman2> I've had no problems with Class 6
[5:35] <mfletcher> but after boot, performance diff is negligible?
[5:36] <pksato> only for massive 'disk' access.
[5:37] <mfletcher> ok thank you!
[5:38] <mfletcher> I bought a wifi dongle for my raspi from adafruit and have spent a good bit of this evening getting it on the network??? was fun!
[5:38] <mfletcher> Its funny but something you take for granted on other platforms/os's is trivial to achieve, but you get more satisfaction when you get it working on Linux :)
[5:40] <clever> most of it is just down to setup, and some distro's have things pre-configured more then others
[5:40] * techman2 (~glen@unaffiliated/techman2) Quit (Quit: Sphinx may be image of a failed attempt to cross humans with lions.)
[5:40] <clever> android is an extreme case, because the hardware and 'os' are locked to eachother, so everything can be configured perfectly
[5:41] <clever> most android devices run wpa_supplicant, just like linux
[5:42] <mfletcher> wanted to configure it from the command line - would have been easier to do it through the gui, but Im running the raspi headless, so wanted to understand how to configure it via the cli
[5:42] <clever> wpa_supplicant can also be done from cli
[5:42] <clever> wpa_passphrase network password
[5:42] <clever> run this and it gives you a portion of the config file
[5:43] <clever> wpa_supplicant -iwlan2 -Dwext -c/root/wlan1/wpa_config -B -W
[5:43] <clever> then just manualy invoke it (or use the proper init.d script)
[5:43] <clever> and man pages!
[5:44] <clever> -W isnt needed, but helps to automate the next steps (dhcp)
[5:45] <mfletcher> ok thank you! will read the man pages. actually ended up butchering /etc/network/interfaces so if theres a cleaner way I'll try it
[5:48] <clever> wpa_supplicant can also be configured to use wep or nothing at all
[5:48] <clever> ive got mine setup to auto-connect to every network i have the pw for, and then fall back to open networks for when i'm not home

[6:39] <windsurf_> hm. pi cloner looks interesting
[6:39] <Grievre> dd?
[6:39] <Scriven> windsurf_, rsync over ssh?
[6:40] <windsurf_> i don't think rsync is the right tool, it won't catch partitions etc.
[6:40] <windsurf_> maybe dd.
[6:40] <windsurf_> gonna try pi cloner first.
[6:40] <Scriven> depends on what you want to back up I guess.
[6:40] <windsurf_> like if i wanted to restore from an image on a new sd card and have it boot up
[6:40] <windsurf_> not just some project files within
[6:40] <windsurf_> i do love rsync though
[6:41] <Scriven> I figure it's easy enough to do the partitions and stuff, it's the data I want.
[6:42] <Scriven> I'll let raspbian/distro do it's thing and I'll repopulate my stuff afterwards.
[6:43] <windsurf_> well, i installed Node.js and some stuff
[6:43] <Scriven> bah, have to sleep soon.
[6:43] <windsurf_> would love to just have that without recompiling which took quite a while the first itme

[6:46] <ohhmaar> So after installing raspbmc will i have to do anything for it to recognize my external hard drive?
[6:46] <ohhmaar> or should it recognize it itself?
[6:46] <chupacabra> Bill Gates and Intel kept beige boxes THE form factor for 40 years. how stupid and greedy
[6:47] <shellbackpacific> did a temperate sensor project (http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/temperature/). Works fine???just don't understand how the resistor fits into the whole thing. Anybody know why a 3.3V temperature sensor requires a 4.7kOhm resistor ?
[6:48] <shellbackpacific> more of a basic electronics question i suppose
[6:48] <windsurf_> shellbackpacific: is it a onewire sensor?
[6:48] <shellbackpacific> yes
[6:48] <windsurf_> shellbackpacific: just finished a project with those myself.
[6:49] <shellbackpacific> yes this one was pretty straightforward to set up???.i'm a programmer trying to learn more about electronics. Having a blast so far with the Pi
[6:49] <chupacabra> Google Fiber coming to Austin?.this could be awesome...
[6:49] <windsurf_> the resistor is a pull-up resistor. someone else could explain it better that I but here's my take. the one wire sensors are digital, not analog, so they talk in 1's and 0's, on's and off's (HIGH/LOW). When there's power coming through the one wire it's HIGH
[6:50] <windsurf_> but, when it's not, it's not LOW, it's a 3rd state
[6:50] <windsurf_> where the electricity can flow kind of wacky and flip between high/low i gather
[6:50] <windsurf_> so the resistor kind of filters out that low noise
[6:50] <windsurf_> forcing the signals to all be within a threshold or something like that
[6:50] <windsurf_> 'pull up' resistor
[6:50] <shellbackpacific> interesting???so it does more than "resist" i guess?
[6:51] <windsurf_> shellbackpacific: i guess it resists a minimum amount to mask out ambiguity in the voltage
[6:51] <windsurf_> like that randomness would happen below that voltage i guess so low has to still be at a minimum amount, above that resistance.
[6:51] <windsurf_> something to that effec.t
[6:52] <windsurf_> shellbackpacific: may i ask what you did with your project?
[6:53] * ngc0202 (~ngc0202@unaffiliated/ngc0202) Quit (Ping timeout: 240 seconds)
[6:53] <shellbackpacific> sure???set up the temperature sensor in my garage to read inside. Also got outside readings from a local airport. After that wrote a python script to log both and the current time in a sqlite db. Then set up a cron job to run every 20 mins. After that, wrote a little nodejs server to server the data up
[6:54] <shellbackpacific> trying to see how well my garage retains heat
[6:54] <windsurf_> cool. so meteorology at the airport and insulation in the home eh?
[6:54] <shellbackpacific> yeah pretty much
[6:55] <windsurf_> how are you communicating with the arduino with py?
[6:55] <shellbackpacific> want to do much more
[6:55] <shellbackpacific> not using arduino..just the pi
[6:55] <shellbackpacific> sits in my garage and i ssh into it
[6:55] <windsurf_> ah right, forgot which channel i was in
[6:56] <clever> windsurf_: its more the one-wire protocol, then digital vs analog
[6:56] <Crenn-NAS> Starting to look like a 3D printer now :D https://twitter.com/crennsmind/status/320398406210162688/photo/1
[6:56] <clever> windsurf_, shellbackpacific: when doing a search for sensors, many sensors can transmit at the same time
[6:56] <shellbackpacific> clever: so something like this wouldn't require a resistor? http://www.parallax.com/tabid/768/productid/50/default.aspx
[6:56] <clever> to prevent a dead short (+3.3 and 0 sent at the same time), it just never sends +3.3, ever
[6:57] <clever> shellbackpacific: yeah, thats simple, one in, one out
[6:57] <clever> so the output will always drive the line
[6:57] <shellbackpacific> clever: ah so the resistor prevents 3.3v from ever happening. that's the point?
[6:57] <clever> no, the resistor is the source of 3.3v
[6:57] <clever> the temp sensors either output 0v, or nothing
[6:58] <clever> so you need the resistor to set the level when nothing is sent
[6:59] <shellbackpacific> hm???still not quite getting it yet
[7:00] <clever> what happens if 2 devices try to drive the wire at once?, +3.3v from one and 0v from the other?
[7:00] <shellbackpacific> guess i'll read more???any advice for references?
[7:00] <shellbackpacific> not sure honestly
[7:00] <clever> in an idea design (0 losses everywhere), you would get infinity amps going between the 2 :P
[7:00] <clever> magic blue smoke coming out of everything!
[7:01] <shellbackpacific> ha
[7:01] <clever> by design, the one-wire devices never send +3.3v on the bus
[7:01] <clever> only 0v
[7:01] * s1gk1ll (~sigkill@bl10-110-29.dsl.telepac.pt) Quit (Ping timeout: 252 seconds)
[7:01] <clever> so it wont fry anything when 2 things try to transmit at once
[7:01] * windsurf_ (~windsurf_@50.68.72.180) Quit (Quit: windsurf_)
[7:01] <clever> but if none of the sensors are sending data, the wire is left floating
[7:01] <clever> and wont have a set level
[7:02] <shellbackpacific> so how would that contrast with this parallex lcd i mentioned: http://www.parallax.com/tabid/768/productid/50/default.aspx
[7:03] <shellbackpacific> that's not 1-wire
[7:03] * pksato (~PEBKAC@unaffiliated/pksato) Quit (Quit: Problem Exists Between Keyboard And Chair)
[7:03] <clever> the resistor lets the data line reach 3.3v when nothing is sending
[7:03] <clever> each wire only has 1 in and 1 out
[7:03] <clever> so you never have to deal with the problem of multiple outputs
[7:04] <clever> the outputs are 0v or 3.3v, simple
[7:04] <shellbackpacific> ah so the "1-wire" refers to one wire for all i/o ?
[7:04] <clever> yeah
[7:04] <shellbackpacific> ah ha ok
[7:05] <clever> one-wire devices can also run without the power line, but thats optional
[7:05] <clever> needs more specialized setup
[7:05] <shellbackpacific> so that means a resistor is not necessary for that lcd since it's not 1-wire and has a 5v power req?
[7:05] <shellbackpacific> interesting
[7:05] <clever> and if the lcd runs at 5v, you need to be carefull
[7:06] <shellbackpacific> haha???blue smoke time?
[7:06] <clever> if thats a standard lcd driver, then the 8 data lines are bi-directional
[7:06] <clever> and there is another pin to set the direction
[7:06] <clever> so they can either be inputs to the lcd (drawing on the screen)
[7:06] <clever> or outputs, back to the pi
[7:06] <clever> but, the lcd runs at 5v, and the pi cant handle 5v
[7:07] <clever> so you need to tie that direction pin to whatever rail sets the lcd as the input (i forget, read the datasheet)
[7:07] * mikey_w (~mike@va-71-51-10-117.dhcp.embarqhsd.net) Quit (Ping timeout: 248 seconds)
[7:07] <clever> then the lcd will never output 5v, and you can use it safely
[7:07] <clever> might also be safer to just run the lcd directly on 3.3v
[7:07] <shellbackpacific> ok, yeah if you think 3.3 will work i'll pbly do that
[7:08] <clever> for most devices, its harmless to put too little voltage in
[7:08] <clever> it may not work, but it wont be damaged
[7:08] <shellbackpacific> until i have a better grasp
[7:08] <shellbackpacific> yep
[7:08] <shellbackpacific> awesome thanks for the tips i really appreciate it
[7:08] <clever> http://www.raspberrypi.org/phpBB3/viewtopic.php?f=35&t=16024
[7:08] <clever> and lcdproc would probly be the simplest way to get the lcd up and running

[8:54] <Xabster> Hey, I'm considering a raspberry as a replacement for my laptop since I only watch movies and browse a few select websites on it, while in bed. I'm not sure if XBMC is needed to run/show 1080p movies or if a small linux distro would be better since I want to be able to browse, too.
[8:55] <ShiftPlusOne> You can use any distro (that supports the pi) and omxplayer.
[8:56] <Xabster> i see, so do you think that's the best solution? i don't need a mediacenter really, just a video player
[8:56] <Syliss> are you gonna hook it up to a tv?
[8:56] <Xabster> i just thought that the mediacenter built in distros were optimized for it
[8:56] <Xabster> yes
[8:56] <Xabster> or a pc monitor, maybe, but yes
[8:56] <ShiftPlusOne> Xabster, the media center distros use xbmc, which uses omxplayer as the backend.
[8:56] <Syliss> yeah
[8:57] <Xabster> sure, but there could still be issues with layers and extra features of a small linux distro
[8:57] <ShiftPlusOne> But I am not sure what your expectations are. It won't play just any 1080p video and browsing may be quite slow.
[8:57] <Xabster> it wont?
[8:57] <Syliss> no
[8:58] <Syliss> and yeah browsing can be painful

[8:58] <Xabster> h264 includes 1080p
[8:58] <rymate1234> It definitely does 720p
[8:59] <rymate1234> Which is still HD
[8:59] <Syliss> its codec dependent
[8:59] <Xabster> okay, 720p is fine
[8:59] <Xabster> i'll accept that, but browsing is painful?
[8:59] <Syliss> it can be
[9:00] <Syliss> do you have a 256 or 512mb pi?
[9:00] <Xabster> neither yet, but it will be 512
[9:00] <Syliss> ok
[9:00] <Xabster> i'll probably get it tonight, and i'm exited!
[9:00] <Syliss> what kind of sites do you plan on visiting?
[9:00] <Xabster> facebook, gmail, reddit, imgur
[9:00] <ShiftPlusOne> Again, depends on what you expect. If you think you can fire up firefox with lots of addons and 50 tabs open, you're going to have a bad time.
[9:00] <Xabster> it's bedtime reading/fun
[9:01] <Xabster> i hope to do single/dual tab chrome possibly?

[9:01] <rymate1234> Good luck
[9:01] <Raspiman> but navigation when the movie is playing? verry slow..
[9:01] <rymate1234> Xabster: Chrome doesn't work on the pi. Chromium, however, does
[9:01] <Xabster> yeah, same same but different

[9:02] <ShiftPlusOne> Xabster, it seems like there are people who get a pi and are pleasently surpised with what they get and there are others who complain, even though they use it for the same things. I think it depends on your expectations and it might be best to get a pi and see how it goes. Even if you don't use it for what you intended to, it's still a handy computer to have.
[9:03] <Xabster> indeed
[9:03] <Raspiman> And you can learn basic linux for less money :)
[9:03] <Xabster> i don't have that high expectations i think, but I demand at least 720p if it's to be used for media playback
[9:03] <Xabster> so that's where i am atm
[9:03] <rymate1234> I'm currently trying to get my pi to tether to my phone via USB
[9:03] <Xabster> i hoped for 1080p
[9:03] <rymate1234> And failing
[9:04] <Xabster> Raspiman, less money than install a free VM on your normal PC ? :)
[9:04] <Raspiman> 720p / 1080p will work (.mkv container less then aprox 20GB h.264)
[9:04] <Raspiman> yes, but the raspi is fun m8 :)
[9:04] <ShiftPlusOne> Xabster, like we said earlier, that depends on how the video is encoded. 1080p works great for properly encoded videos.
[9:04] <Xabster> ok

[9:11] <Xabster> how would the raspberry handle being a VNC client instead of browsing itself?
[9:11] <Xabster> VNC via LAN to a server or desktop PC that renders the websites
[9:11] <Xabster> but video playback would be local still
[9:12] <rymate1234> Badly
[9:12] <Xabster> video + a few select websites is all I need, and a velcro'd PI on the back of a monitor would be very cool to have

[10:38] <Tachyon`> hrm, it's Alan Turing, back from the dead
[10:38] <wombledom> Wifi dongle on a hub and an external powered hdd
[10:39] <Tachyon`> you shuold probably use a PSU of at least 1500mA and link out your polyfuse just to eliminate psu errors
[10:39] <wombledom> The thing is that it only freezes when rtorrent is running
[10:39] <Tachyon`> as the polyfuse is the limiting factor
[10:39] <Tachyon`> different psus may give the same symptoms
[10:39] <Tachyon`> as n o more than 750mA can pass through the fuse
[10:39] <wombledom> Its a 1a charger, too low?
[10:39] <[Saint]> No.
[10:39] <Tachyon`> err, well, might be, it depends
[10:40] * [Saint] highly doubts this.
[10:40] <wombledom> All the usb devices are powered on their own too
[10:40] <[Saint]> 1A is fine for that setup.
[10:40] <Tachyon`> doubt as much as you like, I had to use 2 on one of mine, granted it had a 1.8" IDE drive on it but still
[10:40] <Tachyon`> if it were fs corruption I'd expect the errors that go with that
[10:40] <Tachyon`> for example:
[10:41] <Tachyon`> http://www.pokenet.co.uk/misc/files.pi/piwtf.jpg
[10:41] <Tachyon`> that
[10:41] <Tachyon`> silently failing every time just seems odd
[10:41] <Tachyon`> and screams voltage drop to me, but heh
[10:41] <wombledom> I don't get errors though, it just halts
[10:42] <[Saint]> There'll be errors /somewhere/.
[10:42] <Tachyon`> are you running X?
[10:42] <wombledom> Not in my logs either
[10:42] <wombledom> No, its a headless servee
[10:43] <wombledom> server*
[10:43] <Tachyon`> have you tried a different sd card?
[10:43] <wombledom> It just boots the firmware and kernel off the sd and uses the hdd as root
[10:43] <[Saint]> The system wouldn't(read as: shouldn't) just halt without something going wrong and crying somewhere, but they may not actually be making it to the disk.
[10:43] <Tachyon`> if it's headless how would he know
[10:44] <Tachyon`> your system needs a head
[10:44] <Tachyon`> until you've diagnosed this one
[10:44] <wombledom> I've had it freeze with it connected to a monitor, the cursor just stops blinking
[10:44] <Tachyon`> hrm
[10:44] <Tachyon`> that is odd actually
[10:45] <Tachyon`> have you just got the one pi?
[10:45] <wombledom> It might be my really cheap hdd enclosure too, I might try a different external drive
[10:45] <wombledom> I actually have two, one for playing with gpio
[10:45] <Tachyon`> try swapping them, it's /just/ possible you may have a faulty pi
[10:46] <Tachyon`> it's not likely, but it is possible
[10:46] <[Saint]> It is an easy test.
[10:46] <[Saint]> you don;t need another enclosure, you simply need to eliminate the ones you have.
[10:46] <[Saint]> ...for instance, simply try *without* them.

[10:49] <[Saint]> you're testing from the Pi, not the supply itself.
[10:50] <wombledom> Hackerspace?
[10:50] <wombledom> that's weird
[10:50] <[Saint]> Why so?
[10:50] <wombledom> A good way to be seen being a nerd and get bullied
[10:51] <[Saint]> ...and attitudes like that *really* help...
[10:51] <[Saint]> If you think there's something wrong with "being a nerd", that's your problem ;)
[10:52] <[Saint]> People will bully others for anything. Just do what you want. Bothering about what other people think is totally useless :)
[10:54] <[Saint]> Or, to put it another way: Being intelligent and creative doesn't mean you need to hide in your bedroom.
[10:54] <wombledom> Which spots do I test?
[10:55] <[Saint]> http://elinux.org/R-Pi_Troubleshooting#Troubleshooting_power_problems
[10:55] <[Saint]> if you get below 4.75, throw the PSU away - basically.
[10:56] <[Saint]> (don;t really, just use it for something less sensitive)
[10:57] <wombledom> 5.04v
[10:57] <wombledom> Ill test it with everything running now
[10:57] <Raspiman> i use a apple ipod charger, works flawless: http://static.productreview.com.au/pr.products/98675_apple_ipod_usb_power_adapter.jpg
[10:57] <[Saint]> Well, its not the PSU, then. Unless you can measure a notable drop when the HDD spins up...
[10:57] <[Saint]> but, that shouldn;t happen.
[10:57] <[Saint]> However, check anyway.
[10:58] <[Saint]> Raspiman: Yeah - I use a bunch of iPad wall-warts I had lying around.
[10:58] <[Saint]> 5V/2A - works fine.
[10:58] <Raspiman> yes, most cheap chargers dont do the amperes..
[10:59] <[Saint]> Oh - there may be one or two 1A iPod ones in there too actually.
[10:59] <[Saint]> They work fine too, though.

Oh, and here's a $20 voucher for being honest about our shipping errors!"
[11:03] <drobban> what about RS?
[11:03] <[Saint]> So, I got the one I ordered, one free, and a $20 voucher for telling them they messed up.
[11:03] <Raspiman> [Saint] thats nice!
[11:03] <Raspiman> we make it even now :)
[11:04] <[Saint]> Apparently I pointed out to them that they had been shipping people random extra units, so, I guess even despite the free pi and the voucher I still saved them some money.

[12:07] <jks> anyone knows of an easy way to add a beeper, buzzer or similar to the raspberrypi - that doesn't require any extra components? (i.e. I looked at buzzers that required me to add a simple circuit with a zener-diode and a resistor)
[12:08] <gordonDrogon> jks, there are some buzzers you just give voltage to and they go: buzzzzzzzzz
[12:08] <gordonDrogon> or beep.
[12:08] <gordonDrogon> just need to find the right one.
[12:09] <gordonDrogon> but those tend to be power hungry too...
[12:09] <jks> gordonDrogon, would be great if I could fine one... got any suggestions on where to look and "how to know" if I got the right one?
[12:09] * mgbowman (~mgbowman@chello062178011248.4.11.vie.surfer.at) has joined #raspberrypi
[12:09] <jks> I have found tonnes of buzzers for 3.3V on RS/Farnell and places like that... but it doesn't seem easy to pick one that works without building a circuit
[12:10] <gordonDrogon> this buzzes at 2.3KHz http://www.tandyonline.co.uk/components/buzzers-transducers/miniature-3-3v-pcb-buzzer.html
[12:10] <gordonDrogon> however it also needs 30mA - and the Pi Max on GPIO is 16mA.
[12:10] <gordonDrogon> so you'd need a little transistor to drive it.
[12:10] <jks> ah, okay - I though I could drive a bit more from the Pi GPIOs... hmm..
[12:11] <ShiftPlusOne> Can the pi source as much as it can sink, or can it sink more?
[12:11] <jks> I wonder if something exists that could be connected to the +5V on the GPIO and then take a GPIO pin as a signal
[12:12] <gordonDrogon> jks, not a single component, no. you'll likely blow up the Pi's gpio input
[12:12] <gordonDrogon> ShiftPlusOne, AIUI it's the same each way.
[12:12] <jks> gordonDrogon, ah okay :-|
[12:12] <gordonDrogon> if you can find one of those pizeo discs then you can use a bit of software to make it beep.
[12:13] <spacebug^> you only need a transistor and a resistor
[12:13] <ShiftPlusOne> hm
[12:13] <jks> spacebug^, I don't know any electronics, so I would probably fry off everything before I even got started :-)
[12:13] <spacebug^> hehe ;)
[12:14] <spacebug^> well then you could by the extension card
[12:14] <gordonDrogon> http://en.wikipedia.org/wiki/File:Electronic_component_piezo.jpg
[12:14] <jks> I found something called the "Berry Board" that has a buzzer that can be plugged right into the RPi... but unfortunately it is not sold as a finished product... you have to make it yourself
[12:14] <spacebug^> oh wait, maybe that was to build oneself also

[12:15] <jks> so perhaps if a breakout board exists with RFID and an LED or a beeper that could be software controlled... that would be fantastic
[12:16] <wombledom> Argh my rpi froze again :(
[12:17] <wombledom> Its a different pi, different drive, different wifi...
[12:18] <gordonDrogon> http://www.youtube.com/watch?v=Ij_HR_kr_eg <- something I'm experimenting with :)
[12:18] <jks> hehe, reminds me of the 80s
[12:19] <gordonDrogon> that's an 80?? speaker though - I'm almost certianly abusing the gpio pin it's connected to ...
[12:19] <gordonDrogon> don't try this at home, etc. ;-)
[12:19] <gordonDrogon> right - the coop calls. out of flour error!
[12:19] <ShiftPlusOne> Didn't know you were a musician too =D

[12:38] <gordonDrogon> Raspiman, you can - but that program won't do anything with it - it was just a quick demo program for something else. the soft-tone library will play multiple tones at the same time.

[12:39] <Raspiman> nice, so you can make cords with multiply speakers

[12:40] <Raspiman> my wifes want to know :)O
[12:41] <gordonDrogon> the trick would be to mix it in software, however this really is 1-bit audio output - it's right back to the Apple II days!
[12:41] <Raspiman> thnx for your answer
[12:41] <gordonDrogon> there are better ways to play sounds on the Pi using the "proper" sound system & the hdmi output or 3.5mm jack...
[12:42] <Raspiman> yes haha

[14:34] <gordonDrogon> the USB is the bottleneck in it all - try storing to local SD card then copying it to USB drive after the download ends?

[14:39] <gordonDrogon> you're SD isn't going to wear out during the lifetime of the Pi unless you're really really really thrashing it 24/7
[14:39] <chithead> even then probably not
[14:39] <wombledom> Wait pi's don't last that long?
[14:40] <wombledom> I always thought too many write actions at once on an sd will fry it

[14:41] <ShadowJK> your powersuplly is likely to fry things before 5 years or so

[14:41] <ShadowJK> "at once" is irrelevant
[14:42] <jelly1> It will probably die when you stop using it
[14:42] <ShadowJK> nid0; more like 3000-5000 actually, but that's still a long time

[14:44] <jelly1> well both
[14:44] <ShadowJK> nid0; well if you've got a card with slc flash, the endurance is indeed around 100k
[14:44] <ShadowJK> mlc around 10k, and tlc around 3-5k

[14:44] <ShadowJK> for the raw flash cells
[14:44] <gordonDrogon> I'm still not convinced wear leveling works at all on SD cards.
[14:45] <ShadowJK> even mlc is kinda hard to find in a sd card these days..
[14:45] <ShadowJK> gordonDrogon; dynamic only, most likely
[14:45] <gordonDrogon> and of-course dd'ing 2GB into it more or less removes any leveling that could be done in those sectors.
[14:45] <IalexI> does anyone have experience with running the pi 24/7 for a longer time?

[15:05] <tebruno99> not to hard on the Pi though
[15:05] <nid0> that doesnt change the fact that a good chunk of it will still end up getting cached, you need to sync if you're going to produce a figure that isnt baloney

[15:36] <LambdaDusk> I notice some programs take up less ram on the Pi than onb my PC, is that just an illusion?
[15:37] <yeik> LambdaDusk, what sort of programs?
[15:38] <LambdaDusk> yeik: Haskell compiler, gcc, my own test programs

[15:39] * nomous (~nomous@78.209.173.133) has joined #raspberrypi
[15:39] <LambdaDusk> so when less is available, linux will assign less?
[15:39] <LambdaDusk> but are they actually smaller when compiled for ARM or is that just a coincidence? I couldn't find a good answer online
[15:39] <yeik> not sure about your own programs. unless you include a lot of stuff. but to notice much memory it would have to be a large program anyway. most things are very small
[15:40] <yeik> I don't really know, might want to go to a gcc/haskel room and ask if they have noticed. i haven't tried compiling anything yet.
[15:42] <LambdaDusk> i was afraid the ghc will not run because of the 512 MB but it doesn't even use half of that - unlike the x86 counterpart
[15:43] <yeik> it also doesn't have the cpu power to process as much
[15:43] <tombrough> In theory RISC systems such as ARM should take more instructions not less than x86 CISC systems.

[15:46] <LambdaDusk> yes but the ARM has way more registers to use, reducing the need for local variables to be put on in the RAM and thus less read/write instructions, too?

[20:02] <FergyA> Hey clever, you wouldnt know by chance if I need to hook up both RTS and CTS if I'm only sending in one direction?
[20:03] <kaste> zastaph: it's the less ressource hungry of the two I believe
[20:03] <FergyA> I'm hoping to get away with just hooking up CTS
[20:04] <clever> FergyA: i believe you can get away with one, for the high bandwidth direction
[20:04] <FergyA> great
[20:04] <FergyA> going to give that a try ^^
[20:04] <clever> FergyA: but i forget what one that is, the xbee datasheet should clearly show which one means the input buffer is full
[20:04] <FergyA> yeah, pretty sure its CTS
[20:05] <clever> if the oposite line is disabled in the xbee, then the xbee should ignore it, and transmit always
[20:05] <FergyA> CTS clears the pi to send to the xbee, RTS clears the xbee to send to the pi
[20:05] <FergyA> and since taking it high = stop not connecting it i dont think would do anything
[20:05] <clever> i think the 2 can be enabled seperately in the xbee firmware
[20:06] <FergyA> yessir they can
[20:06] <FergyA> why they didnt put CTS on P1-GPIO I don't know :/
[20:06] <FergyA> not liking having to run another wire
[20:06] <Litecoin> clever, will an old PATA drive run as fast as SD?
[20:06] * f8ld is now known as f8l
[20:06] <clever> Litecoin: the write times may be better, but seek times will obviously be worse
[20:07] <clever> i think the usb is going to be the bottleneck for bandwidth, not the pata interface
[20:07] <clever> FergyA: in the case of AVR chips, they only have a 1 byte buffer, and no real flow control in hardware
[20:07] <Litecoin> yeah, especially when I use USB Wifi adapteur as well
[20:07] <clever> FergyA: so all flow control has to be implemented in firmware, within the received irq
[20:08] <clever> FergyA: not sure about the xbee, but if its the same, that makes it easy to do odd setups
[20:08] <FergyA> we will see ^^

[20:09] <clever> something else you could use, to reduce the errors more
[20:09] <FergyA> I wish I could use one of the NC wires on my ribbon cable to get this across...
[20:09] <clever> the xbee api mode
[20:09] <FergyA> yeah, i did consider that
[20:09] <clever> in api mode, you send the xbee packets, with checksums
[20:09] <clever> so if the checksum isnt valid, it wont send it over the air
[20:09] <FergyA> but theres really not a lot of software out there which supports that
[20:09] <FergyA> and i dont feel like making a program to do it
[20:09] <clever> yeah, i had to write custom software for both ends
[20:10] <FergyA> hoping this will work
[20:10] <Hopsy> I see a raspberrypi logo when my raspberry pi boots, how do I remove this?
[20:10] <FergyA> the manual flat out says "if sending messages greater than 1000 bytes you must enable flow control"
[20:10] <clever> another neat feature of api mode
[20:10] <clever> the source address is in the packets

[20:12] <clever> launching the pi into space?
[20:12] <FergyA> only about a mile up :P
[20:12] <clever> lol
[20:12] <clever> id use the pi as a base station (hdtv to monitor things!)
[20:12] <clever> and then use another xbee + avr as the rocket

[20:13] <FergyA> sending it up in that :P
[20:13] <clever> accelerometers also need adc's often
[20:13] <clever> another need for an avr

[20:13] <FergyA> we're doing all our altitude calcs with a barometer

[20:14] <clever> oh, i just had an idea
[20:14] <clever> the xbee has an adc built into it
[20:14] <clever> and can be programed to take readings, and fire them off over the air
[20:14] <clever> without any microcontroller
[20:14] <FergyA> part of me regrets that though as I wish I had the ability to sense launch, which is super hard to do with a baro

[20:15] <clever> assuming you dont loose the rf link, the base station can process it all
[20:15] <FergyA> the requirements of the project we're working on only requires we collect the data on the ground
[20:15] <FergyA> so im not super concerned with live telemetry
[20:15] <clever> perfect
[20:15] <clever> oh
[20:15] <FergyA> as i fully expect to lose the link
[20:16] <FergyA> the thing pulls 8 gs off the pad and goes ~mach 1
[20:16] <clever> youll want an avr and maybe flash then, to log data
[20:16] <clever> there are boards designed for just this too
[20:16] <clever> *gets link*
[20:16] <FergyA> yeah, but theyre super expensive from what id seen :P
[20:16] <syntac> clever, is x0vncserver supported on rpi? is there an install/setup guide that you know of?
[20:16] <clever> syntac: i havent tried it, but its in one of the vnc packages in apt-get
[20:16] <clever> FergyA: https://www.sparkfun.com/products/9530
[20:16] <FergyA> our sensors are all handled by an arduino, and the pi is in charge of GPS, camera, and wireless
[20:16] <clever> FergyA: cheaper then a pi
[20:17] <clever> FergyA: logs serial directly to an uSdcard

[20:18] <FergyA> and the GPS? and the non-serial camera? :P
[20:18] <clever> then give a single stream, like gps:.... baro:... into the openlog
[20:18] <clever> camera, thats a bit more complex
[20:18] <FergyA> camera was the main reason I went with a pi
[20:18] <clever> the openlog may have some lenght-prefixed modes
[20:19] <clever> another option, more manual, and it depends on how much data you need to store
[20:19] <clever> https://www.sparkfun.com/products/301
[20:20] <clever> 2mbyte of flash, $2.95, how much video would that hold?
[20:20] <FergyA> about .005 seconds :P
[20:20] <clever> ok, that wont work
[20:20] <FergyA> considering we're capping at 1080p 30fps
[20:20] <clever> lol
[20:20] <Gadgetoid> Shazam!
[20:20] <clever> id say either go with a plain old gopro
[20:21] <clever> or maybe https://www.sparkfun.com/products/9802
[20:21] <FergyA> yeah, problem with that is the project requires that we recover it remotely
[20:21] <FergyA> soooo
[20:21] <FergyA> pi it was :P
[20:21] <clever> download the data after it lands?
[20:21] <clever> without picking it up?
[20:21] <FergyA> precisely
[20:21] <clever> ah
[20:21] <FergyA> that is the requirement
[20:22] <FergyA> from up to a mile away even...
[20:22] <clever> the arduino and xbee could be setup to read the sd card back out, after it lands
[20:22] <clever> but the data rates are pretty slow, for 1080p 30fps
[20:22] <FergyA> yeah, the video fortunately isnt required
[20:22] <clever> id download the gps logs, or just get a live gps feed
[20:22] <clever> then go find it :P
[20:22] <FergyA> as thats something we added on
[20:23] <FergyA> that's the plan, though we have a dog tracker in the nose cone
[20:23] <SpeedEvil> what do you want to read out?
[20:23] <FergyA> we need to read pressure, temperature, humidity, UV radiation, and irradiance
[20:23] <SpeedEvil> over several k will be providers
[20:23] <FergyA> while capturing pictures that are horizontal regardless of the orientation of the rocket

[20:24] <clever> neat
[20:24] <FergyA> the back end is the camera gimbal, middle the pi and sensors, and the forward the altimeters
[20:25] <clever> i would put something like rubber bands on both of the hoops at either end
[20:25] <clever> to shock absorb the main body
[20:25] <clever> suspend it

[20:38] <clever> i dont know of any way to make it reuse the existing x session
[20:38] <FergyA> its a separate session to what would be on the tv
[20:39] <clever> same as the vnc server
[20:39] <syntac> i couldn't attach to display :0 for instance?
[20:39] <clever> thats what x0vncserver is for

[20:40] <clever> vncserver is a bash script, that simply helps to setup Xvnc4, which is a fully self-contained X and vnc server
[20:40] <clever> x0vncserver acts as an X11 client, polling the screen, and providing vnc server
[20:41] <clever> there is also a vnc module you can include directly into the server, by modifying xorg.conf
[20:41] <clever> hmmm, i'm seeing corruption on my sd card all of a sudden....
[20:41] <clever> i'll have to fsck it once i find the package
[20:42] <clever> syntac: i think its in the tightvncserver package

[20:47] <drobban> syntac: well. What I know it should be possible to connect to the Xorg server remotely, I have not done this my self, I used gdm to do that, but perhaps this article can be to some help http://www.infoworld.com/t/platforms/how-connect-remote-x11-hosts-mac-616
[20:47] <syntac> i was browsing around and it doesn't look like the package is available on arm
[20:47] <drobban> the article is aimed towards mac users, but same same.
[20:47] <syntac> great thanks i
[20:47] <syntac> *i'll take a look
[20:48] <clever> that method doesnt need Xorg at the pi at all
[20:48] <clever> and just uses the 'local' display directly

[20:53] <TheBrayn> which is the latest version of the linux kernel that runs stable on the rpi?
[20:53] <syntac> i think i'll just spend the money and buy a htpc :p
[20:53] <syntac> clever, thanks for the info on x0vncserver though that'll be helpful in the future
[20:54] <clever> syntac: its only a software problem, you can just compile x0vncserver from source

[21:16] <gordonDrogon> I have looked at hacking that into the gpio program, but I'm in 2 minds about it though.

[21:19] <FergyA> if it were the other way around id be in business
[21:20] <gordonDrogon> there was a lot of decisions made at the time re. GPIO, etc. I think we got a good compromise.
[21:20] <bin_bash> I'm running arch-arm with openbox and obmenu and I want to use xdg-menu and I installed archlinux-menus and python-xdg and openbox-xdg and I added the entry to the rc.xml file

[21:21] <bin_bash> idk wtf i'm doing wrong
[21:21] <FergyA> yeah, its just that RTS isnt all that useful from what ive read
[21:21] <FergyA> whereas CTS is going to be the one you typically need
[21:21] <clever> FergyA: the rev1 board didnt have P5 at all
[21:21] <FergyA> yeah, i know
[21:21] <FergyA> im definitely glad its there

[21:23] <clever> ive heard that the ethernet chip eats a decent ammount of power

[21:27] <clever> gordonDrogon: do you know if the pi supports non-standard baud rates?
[21:27] <gordonDrogon> clever, there's a magic rune you can put in /boot/config.txt to change the clock going into the baud rate generator - I've seen it used for midi for example, so I guess the answer is yes, but you'll need to do some searching to find the right runes.

[21:31] <FUZxxl> I heard from several people (including me) that their Pi was suddently down. May it be possible that there are heat issues?
[21:31] <gordonDrogon> clever, might work - the main issue is getting the baud rate from userland into the kernel - they're all pre-defined constants.
[21:31] <clever> gordonDrogon: hmmmm, i see references to bootcfg.txt in the start.elf file
[21:31] <clever> oh
[21:31] <clever> i wondered where the blockage was

[21:36] <clever> FergyA: its likely the accuracy of the baud rate
[21:36] <FUZxxl> It might be that the fact that I ran some CPU intensive computations led to a temparature spike
[21:36] <clever> gordonDrogon: do you know if the baud offset is 'stable'?
[21:36] <FergyA> yeah, i figure...
[21:36] <gordonDrogon> clever, no idea really - I've only ever used it at 115200 baud ...
[21:36] <gordonDrogon> FergyA, does seem odd though - I presume they're not responding to peoples requests?
[21:36] <FergyA> wish i could :P
[21:37] <clever> FergyA: hmmmm, if its a similar problem to the avr's, higher baud rates may work better, due to how the division works
[21:37] <FergyA> well the only baud rate left is 230400
[21:37] <clever> 115200 had too many errors?
[21:37] <FergyA> yup
[21:37] <FergyA> im going to try one other thing first though
[21:38] <FergyA> going to switch over to UART1 and see if its any better

[22:11] <na85> FergyA: from what i'm reading it seems the PL011 uart is inaccessible because the pins aren't connected to the expansion header
[22:11] <FergyA> yeah, its odd
[22:11] <na85> (which seems rather silly, but...)
[22:11] <FergyA> im getting so much conflicting info its ridiculous
[22:11] <na85> yeah same
[22:11] <FergyA> i have 2 sources that say that gpio 14\15 can be mapped to uart0 or 1
[22:12] <FergyA> and 2 sources that say it cant
[22:12] <FergyA> one of which is the project wiki...
[22:12] <gordonDrogon> :)
[22:12] <FergyA> the wiki being one that say you can
[22:12] <gordonDrogon> give me a mo and I'll check the hardware manual.
[22:12] <FergyA> cool, thanks
[22:13] <na85> apparently there are alternative tx/rx pins in the 30's somewhere
[22:13] <FergyA> yeah, those arent hooked up though :/
[22:13] <gordonDrogon> Yes, you can change the functions of pins BCM_GPIO 14/15 from uart 0 to uart1
[22:14] <gordonDrogon> ALT0 is uart0, ALT5 is uart1.
[22:14] <FergyA> ok, and do you have any idea how i can enable uart1? I've mapped the pins
[22:14] <FergyA> ive got it set to alt5
[22:14] <mgottschlag> shouldn't linux per default use that uart?
[22:14] <FergyA> but have no idea what device to talk to, I dont see a ttyAMA1...
[22:14] <gordonDrogon> I think to enable ama1, you need to first write the kernel driver for it.
[22:15] <mgottschlag> I thought, uart1 was the PL011 uart used by linux, and uart0 the mini uart which isn't used by anything
[22:15] * FergyA bangs head on desk
[22:15] <gordonDrogon> from a freshly booted pi:
[22:15] <gordonDrogon> | 15 | 14 | TxD | ALT0 | High |
[22:15] <gordonDrogon> | 16 | 15 | RxD | ALT0 | High |
[22:16] <na85> FergyA: if you need full uart you could use an I2C breakout
[22:16] <gordonDrogon> Linux (or more likely the bottloader) sets them to ALT0.
[22:16] <FergyA> I just need a UART that doesnt have a broken clock
[22:16] <na85> FergyA: 555 timer on a PCB? lol
[22:17] <mgottschlag> the divisor of the mini uart can be set very flexibly, but you probably have to modify the driver
[22:17] <mgottschlag> (if your clock is off by a constant frequency - if it changes too much, then that's a different problem)
[22:17] * Jck_true (~jcktrue.d@unaffiliated/jcktrue/x-390518) Quit (Read error: Connection reset by peer)
[22:17] <FergyA> yeah, but to make things worse i dont have a scope to find out what im off by
[22:17] <FergyA> so i get to use the imperial method
[22:17] <FergyA> aka trial and error
[22:18] <mgottschlag> last time I had such a problem, I let the divisor register count from 1 to 255 while transmitting data (but that was on bare metal, no linux, and I did it because I didn't know what frequency I was running at)
[22:19] <mgottschlag> that way I saw which range worked, and could just take the center of those values
[22:19] <gordonDrogon> page 176 of the manual: the uart on the Pi is the "full" uart and that's ALT0 on pins 14&15.
[22:19] <mgottschlag> a lot of work though
[22:19] <na85> FergyA: couldn't you rig up a breadboard to compare your output frequency to a known frequency?
[22:19] <FergyA> I do have a frequency counter actually
[22:20] <FergyA> i could try hooking it up to that
[22:20] <FergyA> just remembered i had one on my multimeter :P

[22:23] <clever> FergyA: maybe you had the wrong hardware flow control one?
[22:23] <gordonDrogon> Obvous question, but I'm presuming you're tested the xbees on some other device first?
[22:23] <FergyA> maybe... ill give it a try in a min here
[22:24] <FergyA> i have, i can send data from my desktop to laptop nps
[22:24] <gordonDrogon> what baud rate are you using on the Pi?
[22:24] <FergyA> im trying to use 115200
[22:25] <gordonDrogon> oh ok.
[22:25] <FergyA> but when i do i get garbage out the other end
[22:25] <gordonDrogon> I've used that to program ATmegas in the past and to exchange a lot of data with them.
[22:25] <FergyA> only baud rate that works without losing like everything is 9600
[22:25] <gordonDrogon> also to drive the 4D systems displays - exchanging a lot of data with them too.
[22:25] <FergyA> and id rather not send 5ish megs at 9600 baud ty :P
[22:25] <gordonDrogon> You know that there is a bug when you open the serial port? It sends a spurious byte down?
[22:26] <FergyA> yeah, ive noticed that
[22:26] <clever> he
[22:26] <mgottschlag> actually, the pl011 uart also has a clock which can be freely modified
[22:26] <FergyA> i know
[22:26] <clever> gordonDrogon: he was sending large files with minicom and zmodem
[22:26] <FergyA> i wish i could get to the dang thing
[22:26] <clever> gordonDrogon: it only opens the port once
[22:26] <gordonDrogon> so keep the port open - ok.
[22:27] <FergyA> yeah, arch doesnt have a driver for it either it seems :/
[22:27] <gordonDrogon> have you tried a hard-wired link between Pi & desktop too ?
[22:27] <clever> FergyA: i have a crazy idea
[22:27] <clever> FergyA: run ppp on ttyAMA0
[22:27] <clever> then you will be sending tcp/ip frames, with checksums and auto retransmit
[22:27] <clever> then you can just ftp the files out
[22:28] <FergyA> yeah, i was thinking that or ssh

[23:26] <gordonDrogon> the pl011 is the current ama0...
[23:26] <FergyA> eh, what i read said the pl011 is UART1...
[23:26] <FergyA> god i love the amount of misinformation on this
[23:26] <gyeben> well, you can add "current_limit_override=0x5A000020" into your config.txt
[23:26] <gyeben> but I don't really understand what it does
[23:27] <FergyA> gordonDrogon: http://lavalink.com/2012/04/more-on-raspberry-pi-serial-ports/ is what I was referencing
[23:28] <FergyA> it very well could be wrong though
[23:30] <gordonDrogon> FergyA, it's not wrong, but it's not really telling you anything other than that the pl011 is the uart used on the Pi on gpio pins 14/15.
[23:30] <na85> gyeben: when you set it to 0x5a000020 it disables the SMPS current protection
[23:30] <gordonDrogon> it confuses things though by mentioning that the miniuart is good for console - when it's not used at all in the pi.
[23:31] <na85> gyeben: if you're overclocking your pi, then the overvoltage can draw more current than the power supply will allow you to source
[23:31] <na85> gyeben: so if you disable the current limiting, you can avoid that problem
