[0:01] <CeilingKitten> ownCloud 5.0.9 (up to date)
[0:03] <CeilingKitten> PetRock's install script uses varnish http accelorator? but i noticed on connect it shot to 97% in top
[0:03] <CeilingKitten> so maybe the varnish is the problem
[0:03] <CeilingKitten> im done a reboot too so we'll see if it gets usable
[0:03] * coolty (~coolty@unaffiliated/coolty) Quit (Ping timeout: 246 seconds)
[0:04] <nid0> varnish is kinda pointless with owncloud
[0:04] <nid0> its basically a load of extra overhead and ram used for no real purpose
[0:05] <CeilingKitten> Ah, so i just strip that out.
[0:05] <CeilingKitten> I assume any network accel. software is a trade off of compression
[0:07] <CeilingKitten> I'll give a fresh owncloud install by itself in a little bit =]. I think varnish maybe the issue. i killed it and my phone has sync'd finally :o
[0:07] <CeilingKitten> and the pages seem to be responsive thus far
[0:08] <nid0> well compression isnt the problem and is worth doing with mod_deflate
[0:08] * user82 (~user82@unaffiliated/user82) has joined #raspberrypi
[0:08] <nid0> but varnish is a caching system
[0:08] * Visage (~visage@pdpc/supporter/active/visage) has joined #raspberrypi
[0:09] <nid0> which is kinda pointless with something like an owncloud setup, because its not just read-heavy requests for the same content

[0:10] <shiftplusone> CeilingKitten, I am a little sceptical, but if you get owncloud to a usable state, please make note of the changed you needed to make from a standard nginx+php+mysql install.

[0:17] <CeilingKitten> I'll keep you informed if I do shiftplusone. I will prolly give it anfresh install from scratch tonight
[0:17] <CeilingKitten> a*

[0:22] <apo_> ugh, owncloud :|
[0:23] * debenham (~cjd@122.150.25.53) has joined #raspberrypi
[0:24] <shiftplusone> got something better?
[0:25] <nid0> lots of much much better tools, just a lot more expensive
[0:28] <apo_> shiftplusone: nothing that's open source
[0:28] <apo_> shiftplusone: I've given up and started using spideroak - they encrypt your data so they can't get at it themselves, and give me 7 GB or so
[0:28] <apo_> that's plenty for the stuff I need
[0:30] <shiftplusone> haven't heard of it, thanks.

[2:26] <CeilingKitten> apo_, shiftplusone, SpiderOak is great, not only is it encrypted in transit but only you have the key, where as dropbox your files aren't encrypted on their end, thats how they can delta-sync and save you from uploading the whole file, if its already existing on there server under another user. They also have no problem handing your data over to any authority who asks. =]
[2:27] <apo_> CeilingKitten: I know.
[2:27] <CeilingKitten> SpiderOak, is unique in that aspect i think, compared to most of the other sync/hosts.
[2:27] * uniqdom (~uniqdom@pc-238-64-100-190.cm.vtr.net) has joined #raspberrypi
[2:27] <CeilingKitten> I like Box.com for all their apps, but i dont trust them much either
[2:28] <shiftplusone> I wouldn't keep any data of interest to hackers or 'authorities' online, so that side of it is not a big concern for me. But yeah, spideroak does sound more appealing
[2:28] <uniqdom> Hi guys... about GPIO maximum draw, one GPIO pin can draw maximum 16mA. all GPIO can draw 16mA at the same time??
[2:29] <shiftplusone> does spideroak allow for 'public' files for sharing without making others make a spideroak account?
[2:29] <uniqdom> or the limit is 50 mA as 3.3v pins?
[2:29] <maxinux> shiftplusone: yes
[2:30] <shiftplusone> that settles is then
[2:30] <shiftplusone> thanks

[2:54] * debenham (~cjd@122.150.19.107) has joined #raspberrypi
[2:55] <shiftplusone> damn, just checked the actual cost of arduinos, that's pretty cheap =D
[2:57] * Hydra (~Hydra@46-65-54-87.zone16.bethere.co.uk) has joined #raspberrypi
[2:58] <ricksl> wow that is such a shameless ripoff
[2:58] <shiftplusone> really, how?
[2:58] <ricksl> did you look at a side by side
[2:58] * Hydra (~Hydra@46-65-54-87.zone16.bethere.co.uk) Quit (Client Quit)
[2:58] <ricksl> it looks like they used teh arduino pcb layout
[2:59] <shiftplusone> well, yeah, that's the point. I thought you meant it's a rip off in the sense that it's a scam.
[2:59] <ricksl> the* and the parts look identical as well. I mean it is a good idea the markup on arduinos is crazy
[2:59] <shiftplusone> It doesn't claim to be anything else though
[3:00] <ricksl> Again not saying it is a bad thing.
[3:00] <shiftplusone> ah, fair enough
[3:00] * dreamon__ (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[3:00] <shiftplusone> but still, I am not sure how you can rip off an open source (or creative commons in this case) project, when you give full credit where it's due.
[3:01] <ricksl> I know, I do like that at least someone is trying to fight the markup with these dev boards
[3:01] <debenham> http://blog.arduino.cc/2013/07/10/send-in-the-clones/
[3:01] <shiftplusone> Is it pure markup of actual cost of manufacturing in italy and such?
[3:01] <ricksl> and the fact that it is an identical chip means that there isn't any special support needed for it.
[3:02] <debenham> that page gives a good overview on clones/counterfeits etc
[3:02] * Arbos (~Arbos@unaffiliated/arbos) Quit (Quit: Farewell)
[3:02] <shiftplusone> *or
[3:03] <ricksl> markup + italian manufacturing/shipping i would imagine
[3:04] <shiftplusone> hm

[3:04] * brainwash_ (~brainwash@unaffiliated/brainwash) has joined #raspberrypi
[3:04] <debenham> The markup is used to fund future devel of arduino-related items
[3:05] <shiftplusone> well, that's the case with any company that plans to stick around
[3:05] <shiftplusone> the question is what's reasonable.
[3:05] <ricksl> exactly
[3:05] <ricksl> i mean i like that there is a full time team developing
[3:05] <ricksl> the people working on the arduino project probably use it as their main source of income
[3:05] * LaxWasHere is now known as LaxWasThere
[3:06] <shiftplusone> nothing wrong with that either, they more than deserve it.
[3:06] * Shirakawasuna (~Shirakawa@184-77-202-94.war.clearwire-wmx.net) has joined #raspberrypi
[3:06] <ricksl> but I would love to see their profit margin is all.
[3:06] * scorphus (~scorphus@CAcert/User/scorphus) has joined #raspberrypi
[3:06] <ricksl> i mean these boards with their components and all probably cost less than $15

[3:07] * brainwash_ is now known as brainwash
[3:07] * hyperair (hyperair@ubuntu/member/hyperair) has joined #raspberrypi
[3:07] <shiftplusone> When I can afford it, I don't mind paying extra for products that are manufactured in places where OH&S and a proper minimum wage is an actual thing. But hell, I am not passing on a $9 arduino =D
[3:08] <ricksl> I like seeed studio for that reason, and they are actually really big on education and such in china
[3:08] <shiftplusone> Now, I'll shut up before it sounds like I am advertising or something >_<
[3:11] * spvensko (~spvensko@unaffiliated/spvensko) has joined #raspberrypi
[3:12] <spvensko> how bad of an idea is it to try to use an SSD through the USB port as "RAM" for the RPI by setting it as swap area?
[3:12] <spvensko> i've never had experience with SSD so unsure how fast they are
[3:14] <shiftplusone> spvensko, I don't know for sure, but I expect it would be useless for anything other than preventing complete lock-up if things get out of hand. For that I would just have a swap file on the sdcard and an appropriate 'swappiness' set, which may already be the case.
[3:15] <ricksl> You will wear out the ssd pretty quickly
[3:15] * lrusak (~lrusak@S01060018e7c4b795.ok.shawcable.net) Quit (Read error: Connection reset by peer)
[3:15] <spvensko> shiftplusone: i saw the 32 rpi cluster and it seems like a fun idea but the 512 mb per core seems very limiting
[3:15] * yggdrasil (~yggdrasil@unaffiliated/yggdrasil) Quit (Read error: Connection reset by peer)
[3:16] <spvensko> ricksl: yeah, i can believe it with constant swapping
[3:16] <shiftplusone> I don't know about clusters or their requirements, but it sounds like plenty.
[3:16] <CeilingKitten> (offtopic) anyone used mhddfs ?
[3:16] <uniqdom> about GPIO maximum current draw, I know that one GPIO can draw maximum 16mA. Does all GPIO pins can draw 16mA at the same time?? or the limit is 50mA as the 3.3v pin??

[3:17] <CeilingKitten> i have a series of drives and debating do i sort of concatenate them ? or just let linux put them whereever it wants?
[3:17] <ricksl> Well the swap ssd idea is essentially what those "ssd cache drives" use to speed up performance. But they are almost sacrificial since solid state memory is limited in read/write cycles.
[3:17] <shiftplusone> uniqdom, if you stick around, Gordon is the person to ask that sort of question, but I think he's gone for today.
[3:18] <shiftplusone> and to be fair you won't see the SSD performance over the pi's USB\
[3:18] <uniqdom> ok
[3:18] <spvensko> shiftplusone: i'm interested in creating one for the purposes of bioinformatics/computational biology… 512 MB may be enough but i'm use to working on servers with dozens and dozens of GB of RAM… not sure if my sloopy coding can work in 512 MB :)
[3:18] <shiftplusone> uniqdom, my answer would be that you certainly don't want to draw 16mA from all gpio pins, but I don't know what the max is.
[3:18] <spvensko> shiftplusone: yeah, i figured the USB port speed (right term?) would be very limiting
[3:20] <shiftplusone> spvensko, it's a mobile phone platform, essentially, so it's not perfect to start off with, throw in the fact that ethernet actually goes through USB, and now you're sharing that bandwidth between the SSD and ethernet. I don't have any numbers though.
[3:21] <ricksl> I guess it might depend on how you code your cluster, for example, with the folding@home you get a large workload to compute and then send in the results, but with something that is more distributed you might not need a lot of ram if each node is recieving, processing, then resending the work quickly
[3:21] <spvensko> shiftplusone: thanks for the help

[3:21] <nerdboy> ahoy
[3:21] <spvensko> ricksl: very good point
[3:22] <spvensko> it's definitely just hobby coding (though i hope to be doing something similar as a job soon) so if it's slow it's not the end of the world but i'm attracted to the low power requirements
[3:23] <shiftplusone> CeilingKitten, have you tried this mhdffs you speak of?
[3:24] <shiftplusone> spvensko, take a look at some of the other similar platforms like beaglebone black, cubiebox and ordroid (I may have gotten some names wrong), maybe there might be something more suitable there.
[3:24] <ricksl> i hear (never attempted) that the pi is a good introduction to distributed computing since each node is very cheap (maybe $45 each).
[3:24] * Orionid (~Orionid@cpe-107-10-78-190.new.res.rr.com) has joined #raspberrypi
[3:24] <shiftplusone> ah *cubieboard
[3:24] <nerdboy> spvensko: i'm not a bioinformatics guy, but if you can parcel out the problem small chunks you might do okay...
[3:25] <nerdboy> as ricksl mentioned, the problem data/algorthms will drive it
[3:25] <ricksl> hm beagle bone black might be cheaper and carry a lot more performance with it.
[3:25] <spvensko> i'm so behind the times...
[3:26] <nerdboy> and has faster ethernet...
[3:26] <spvensko> last time i looked into ARM boards there were beagleboards and gumstix :)
[3:26] <spvensko> i need to do some more research
[3:26] <ricksl> how would you compare a beaglebone black to a beaglebone these days?
[3:26] <ricksl> when was the last time the beagleboard got a refresh.
[3:27] <shiftplusone> spvensko, yup, I really can't thank the Pi folks enough for changing the landscape. I wanted to mess around with some embedded platforms for ages, but couldn't justify the expense... now they are all over the place =D
[3:27] <nerdboy> an example would be something like a median filter, where most algorithms are optimized for available memory twice as big as the data set
[3:27] <CeilingKitten> shiftplusone, I have not but my understanding is its like a poor version of a JBOD raid?
[3:27] <CeilingKitten> I ask incase one of the geniuses here knows, I currently have my drives in a windows machine
[3:27] <leming> shiftplusone, they didn't change the landscape; arm platforms, even cheap ones, were around for years before the pi
[3:28] <CeilingKitten> I like the idea of a "single" visible location to organize all my files though
[3:28] <nerdboy> but for a median there's a slower one that works on arbitrarily large data
[3:28] <nerdboy> and it's actually not that much slower as data grows...
[3:28] <spvensko> nerdboy: so much for me to learn :)
[3:28] <spvensko> i'm getting a PhD in genetics and i can code sufficiently to get answers but i'd like to learn how to create more efficient algorithms among other things

[3:28] <shiftplusone> leming, when I looked a few years before the pi all I found were, like spvensko said, gumstix and beagleboards. There may have been things like hackable routers and such, but that's slightly different.
[3:29] <leming> there were loads of armv5 systems
[3:29] <spvensko> shiftplusone: yep, rpis are so affordable… of course back when i was looking i was still in undergrad and i was broke as a joke
[3:29] <shiftplusone> leming, I'll admit I am probably wrong, I am just saying that I couldn't find anything, and maybe I didn't really look hard enough.
[3:29] <spvensko> (looking at beagleboards and gumstix)
[3:29] <ricksl> I picked up 4 zipit z2s this christmas at an electronics shop, $5 each.
[3:29] <leming> the vast majority of which far exceed the pi's capabilities when you exclude video
[3:30] <ricksl> I have yet to flash them since i can't for the life of me find the images that you flash. also i only have one micro to mini sd adapter.
[3:30] <nerdboy> spvensko: specifically, quickselect vs. torben's algorithm in the median case
[3:30] <shiftplusone> ricksl, nice. I've got 2 unopened boxes myself =D
[3:30] <SpeedEvil> Or there is silly stuff.
[3:30] <SpeedEvil> Like nexus 7s with dead digitisers cheap on ebay :)
[3:30] <leming> and contrary to the community's belief, the pi's existence isn't the reason other companies are making boards :P
[3:31] <ricksl> I am sure it isn't the sole reason. but all the embedded dev boards were mainly for android.
[3:31] <shiftplusone> leming, what are examples of boards that exceed the pi's capabilities (GPU aside) that are cheaper and existed before the pi?
[3:31] <spvensko> is there a good general resource for ARM boards? reviews, release announcements, forums, stuff like that?
[3:31] <ricksl> pandaboard ect, there wasn't much in the way of general linux control boards.
[3:32] <ricksl> makezine might have something if you don't mind a bit of digging.
[3:32] <leming> you could look at any of the Marvell Kirkwood powered systems, usually found in cheap NAS-like commercial products
[3:32] <ricksl> the probably did at least one side by side of a handful of arm boards.
[3:32] <nerdboy> the kurobox was around years ago, but somewhat under-powered compared to the average arm device...
[3:32] <nerdboy> 128 MBs ram and 277 MHz ppc
[3:32] <nerdboy> but with GigE...
[3:34] <shiftplusone> leming, i've acknowledged that there may have been routers and other hackable devices other than dev boards, but that's not exactly what I was talking about. Either way, point taken.
[3:35] <leming> there were dev boards too, just that the commercial implementations of those chipsets were the cheaper way to obtain the equipment
[3:35] <leming> specifically, one sitting on my shelf, the OpenRD system
[3:36] <johnc-> is there a pi-like device that's got more a bit more oomph for a similar price point?
[3:36] <ricksl> beagle bone black
[3:36] <shiftplusone> johnc-, leming just gave this example here http://archlinuxarm.org/platforms/armv5/openrd no idea what it costs though.
[3:37] <ricksl> around $45 and arm cortex A8 as opposed to arm11
[3:37] <leming> openrd is a bit harder to come by these days, and likely too expensive for what it is now
[3:37] <spvensko> the cubieboard 2 looks pretty nice
[3:38] <shiftplusone> Anyway, work time. Take care
[3:38] <johnc-> interesting
[3:38] <ricksl> later shift.
[3:38] <johnc-> ricksl, does it do 1080p playback?
[3:38] <ricksl> no, not even close
[3:39] * zokeber (~Zokeber@unaffiliated/zokeber) has joined #raspberrypi
[3:39] <johnc-> heh
[3:39] <ricksl> it has a graphics core that came from about 2005 i think, and the closest to accelerated decoding is a neon media decoder.
[3:39] <leming> johnc-, if you want to factor in the cost of your usb hub, assorted dongles, and misc cables into an adjusted price point, you can get a lot of umph with something like the odroid-u2
[3:40] <ricksl> i have heard good things about odroid.
[3:40] <spvensko> maybe i'm missing something but how is cubieboard different from cubieboard2? just the dual-core nature of the cubieboard 2?
[3:41] <leming> very good platforms, and again, the pi was not a factor in their existence ;)
[3:42] <ricksl> i think thats about it spvensko
[3:42] <johnc-> micro hdmi makes me cry
[3:42] * Orionid (~Orionid@cpe-107-10-78-190.new.res.rr.com) Quit (Quit: Leaving)
[3:43] <ricksl> hm i wonder if there is a way to get opencl access on the cubieboard.
[3:43] <johnc-> odroid looks interesting for sure
[3:43] <spvensko> the page won't load for me
[3:43] <spvensko> ordroid's page
[3:43] <johnc-> is there a video player that supports it's hardware decoding of h264?
[3:44] <spvensko> oh...
[3:44] <spvensko> odroid… not ordroid
[3:44] <ricksl> hm nope thought mali 400 had open cl, they didn't put open cl into their mali line of products until the t604

[11:25] <[Saint]> measureing things in British Queens is an odd unit. :)

[11:30] <kai> [Saint]: but hecto- isn't an SI prefix, so it doesn't really count....
[11:30] <InControl> I don't think Ohm is wither as it is Ω
[11:31] <InControl> *either
[11:31] <kai> right, but transliteration to ascii should be accepted on IRC
[11:32] <apo_> kai: it is
[11:32] <Mjolinor> Ohm is the unit, omega is it's abbreviation
[11:32] <kai> I mean, most of the time I'd also write um, not µm, just because I'm lazy
[11:32] <Mjolinor> not lazy, normal, the whole world does it
[11:33] <apo_> I don't
[11:33] <InControl> trouble is people write uF and mF for µF can be very confusing for newbies
[11:33] <Mjolinor> ?
[11:34] <Mjolinor> no one uses mf for uf, that is confusing as mf are mf
[11:34] <Mjolinor> ie 1mf = 1000 uf
[11:34] <kai> apo_: oh, indeed it is..
[11:35] <InControl> you would be supprised how many times you see mf because it is micro farrad
[11:35] <kai> but that's just plain wrong
[11:35] <InControl> I know
[11:36] <Mjolinor> I have never seen it and for sure if I did they would get sacked :)
[11:36] <InControl> mf is silly because it would be mili
[11:36] <Mjolinor> it is milli
[11:37] <InControl> Zebra label printers are a nightmare, they don't print Ω
[11:37] <Mjolinor> anyway, that's enough frivolity. I need to gracefully shut down my pi. Not a problem with that, I will connect an IO line and if it falls to 0 I will save my databases and shut down. Problem is booting it again when power comes back on without removing power
[11:37] <Mjolinor> any suggestions?
[11:38] * redarrow_ (~redarrow@gateway/tor-sasl/redarrow) has joined #raspberrypi
[11:39] <Mjolinor> there area few boards about for shutting down but none of them are suitable really
[11:39] <InControl> If your circuit is powered by the pi should be easy
[11:39] <InControl> no power to the pi = no power to your circuit
[11:39] <Mjolinor> the only way I can think right now is that when power comes back on I break the supply fomr the battery box to the input on the PI, not a really good solution that
[11:39] <Mjolinor> its not my circuit, its hte PI

[11:40] <ShorTie> thats from anotherday, but answers your ??
[11:41] <Mjolinor> it owuld be nice to be able to put the PI into a mode from which it is sitll working on a really basic level where total power loss wouldnt cause corruption and be able to restor it from that
[11:42] <InControl> Oh I see what your trying to do now you have no choice really to hit the Pi with a reset to make it boot
[11:42] * redarrow (~redarrow@gateway/tor-sasl/redarrow) Quit (Ping timeout: 240 seconds)
[11:42] <Mjolinor> thtas the problem
[11:43] <Mjolinor> if I could shut down everything, caching, whatever but leave it monitoring one IO line that woudl be ideal
[11:43] <Mjolinor> but I siltl fear that in that state it could corrupt the boot device on power loss
[11:43] <BurtyB> InControl, or ground GPIO1/3 if you don't want to mess with P6
[11:44] <InControl> You could change mounts to read only to avoid file system corruption
[11:44] <Mjolinor> I htought about that
[11:44] <Mjolinor> I intend to have my databases in RAM and on [power loss copy tehm to flash under battery power
[11:45] <Mjolinor> it is the other option to make a JFFS2 image but thats a real ball ache, I have done it before on openwrt
[11:45] * omgmog_ is now known as omgmog
[11:47] <Mjolinor> aha, thatr solved it
[11:47] <Mjolinor> THe raspi I am using doesnt have a P6, I googeld it and voila, so I opened a enw raspi and it does have a P6
[11:47] <Mjolinor> so I can simply pulse that on power restore :)
[11:48] <Mjolinor> excellent, thank you

[12:52] <Mjolinor> clever: not at all
[12:52] <clever> Mjolinor: just put ro into your /etc/fstab flags and maybe cmdline.txt and it should never modify the card
[12:52] <clever> that will massively reduce your chances of corruption
[12:53] <Mjolinor> true but a proper shutdown on power loss will reduce the chance to 0 :)
[12:53] <Mjolinor> in theory :)
[12:53] <[Saint]> that's not necessarily true at all.
[12:53] <clever> that requires detecting power loss and providing backup power long enough to do so
[12:54] <Mjolinor> yup, no problem doing that with some nicads and probably a PIC micro to look after ti all
[12:54] * [Saint] (~saint@rockbox/user/saint) Quit (Remote host closed the connection)
[12:54] <clever> ive recently been playing with some lipo's and just ordered an i2c fuel gauge
[12:55] <clever> it runs about 4 hours on a charge, and once the fuel guage arrives, the pi can measure its own battery
[12:55] <gordonDrogon> ShorTie, no...
[12:55] * [Saint] (~saint@rockbox/user/saint) has joined #raspberrypi
[12:56] <Mjolinor> I sort of half hoped there would be soemthign in /proc to tell me supply voltage but cant finfd any reference to anything
[12:56] <Mjolinor> I will jsut use an IO pin for mains fail detect
[12:56] <clever> the pi doesnt have any adc capability
[12:57] <clever> the best you can hope to do is put a voltage dividor on the battery, so 'low battery' divides below the low threshold of gpio
[12:57] <SpeedEvil> clever: Well - the best you can do is a GPIO ADC
[12:57] <clever> a simple 'good'/'bad' status
[12:57] <SpeedEvil> clever: You charge a cap hooked to the GPIO, then you let it discharge through a resistive divider.
[12:58] <SpeedEvil> Time how long it takes to flip.
[12:58] <clever> and without a realtime os, there will be jitter in the timing
[12:58] <SpeedEvil> That's overblown.
[12:58] <SpeedEvil> You measure 5 times, you take the lowest value.
[12:58] * zero_coder (~zero_code@14.195.231.6) Quit (Remote host closed the connection)
[12:58] <clever> works, but then you loose sample rate
[12:58] <SpeedEvil> If it's not 10* the expected value - as it will be if there is an interrupt - you go with it
[12:59] <SpeedEvil> Or if you're feeling clever, you use DMA.
[13:00] <Mjolinor> corruption of the OS isn't my main worry, saving the databases is the msot important thing
[13:00] <clever> Mjolinor: what db format?
[13:00] <Mjolinor> they will run in a RAM disk and have to be copied to flash on power fail
[13:00] <Mjolinor> RRDtool
[13:00] <Mjolinor> at themoment
[13:00] <Mjolinor> whether it stays that way or not depends on what the customer wants to do with the data
[13:01] <clever> if i remember correctly, rrdtool uses a pre-allocated array, and will fill in the existing spots over time
[13:01] <Mjolinor> yup
[13:01] <clever> so it will have to read each block in, change one value, write it back out
[13:01] <Mjolinor> so size is fixed at creation
[13:01] <clever> worst case, you loose all values in that block
[13:02] <clever> and maybe the header saying what value is the newest, which could be worse
[13:02] <clever> i would just make a cronjob that copies the rrd file to a backup location daily, or hourly
[13:02] <clever> and only copy if there is no corruption
[13:02] * ruif13 (~ruif13@a89-153-58-111.cpe.netcabo.pt) has joined #raspberrypi
[13:02] <Mjolinor> I probably will do that as well
[13:03] <Mjolinor> but the most important data in the database will be the data immediately leadign up to a popwer cut
[13:03] <clever> or look into other things that are more hardened against power failure, like innodb or sqlite
[13:03] <Mjolinor> so I have to keep safe all of it right up to the power going off
[13:03] <tig|> you could use a replicated setup
[13:04] <clever> sqlite in the default mode will not return until the data has been flushed fully to disk
[13:04] <tig|> so that in the event of a power failure you will have it right up until it went down
[13:04] <nid0> i've played around with a pi using old-style ramfs quite a lot and simply have a cron executing every minute to check that the ramfs is still viable, then rsync files to hard storage and take a database dump, thats worked pretty reliably for me and at least ensures your data's never more than a minute old
[13:04] <Mjolinor> I knwo bugger all about databases, I find C about 100 orders of magnitude high level
[13:05] <Mjolinor> I like assembler programming and dont want to learn about databases, fi the customer wants it then I will get seomone else to do that part
[13:05] <tig|> Mjolinor: I would use a replicated DB setup that way you would be able to view the data before waiting for the first box to come up
[13:05] <tig|> or even have a second box take over duties
[13:06] <Mjolinor> but Iowuld have to learn how to do that :(
[13:06] <tig|> Mjolinor: it is not that bad actually, find a tutorial on Mysql replication
[13:06] <tig|> that is probably the easiest to get going
[13:06] <nid0> I dunno what your situation is but is a replicated setup gonna do what you want exactly? where's this pi gonna be housed that the power supply's so unstable?
[13:06] <Mjolinor> I suppose it would help my sleeping patterns, for sure that's what would happen if I started reading about Dbases
[13:07] <Mjolinor> http://81.110.238.61/index.php
[13:07] <Mjolinor> that is my PI
[13:07] <Mjolinor> it has a 433 reviever that gets data from remote sensors that will connect to the LV bus bars in a substation
[13:07] * canton7 is now known as that_
[13:07] <nid0> but presumably if you're worried about power loss so badly its somewhere dodgy, using solar, or something simlar?
[13:07] * that_ is now known as canton7
[13:08] <Mjolinor> utilities are beggingin to see the start of a really big problem, they cannot tell which way power is flowing on their network
[13:08] <Mjolinor> distributed generation is the cause
[13:08] <clever> Mjolinor: before they just looked at how much every plant made, and did the math?
[13:09] <Mjolinor> the power supply will be more reliable than most but the raspi can turn its toes up with remarcable reliability if you remoive the pwoer from it
[13:09] <clever> and now there are 2000 small plants they cant measure in realtime?
[13:09] <Mjolinor> thats it
[13:09] <tig|> you could make a UPS for the Pi, simply get one of those big portable device charging batteries (make sure they can pump out 1A and will do while charging) then plug it in to charge then plug the pi in :)
[13:09] <Mjolinor> it is now seriously unsafe for tehm to work on networks, in the past removing the fuses in the sub assured that the network was dead, that is no longer a safe assumption
[13:10] <clever> Mjolinor: thats why regulations exist when hooking backup generators and back feeding stuff
[13:10] <clever> it should disconnect and/or shut down when the incoming power is lost
[13:10] <Mjolinor> the cheapest thing you can buy to clip on the substation bus bar is around £1000
[13:10] <tig|> put a pilite on the gpio headers or similar and you could show some visual feedback
[13:10] <Mjolinor> I can make this one for about £40 per feeder plus one PI per sub

[13:11] <clever> Mjolinor: so its basicaly just a bank of current clamps that connect to the internet?
[13:12] <nid0> well, assuming these pis have net connections, a remote pi somewhere else serving as a secondary db server to duplicate all changes would be easy as
[13:12] <Mjolinor> rogowski coils
[13:12] <Mjolinor> a remote pi wont do, if the power goes off the internet goes off too
[13:12] <clever> Mjolinor: how long would the power remain offline?
[13:13] <Mjolinor> no idea
[13:13] <clever> Mjolinor: and do you need to keep recording when the power is 'out' or just save it and shutdown cleanly?
[13:13] <Mjolinor> it doesnt matter, what is important si that if the power is on it is collecting data and when the power goes off data will be available afterwards right up to the moment of power loss
[13:14] <Mjolinor> just save it and sht down cleanly
[13:14] <Mjolinor> its easy enough, I will run the pi through nicads and connect the nicad supply to an IO pin that starts a shutdown routine
[13:14] <Mjolinor> to reboot when power comes back I iwll use hte falling edge of GPIO3 to initiate a boot
[13:16] <clever> Mjolinor: yep, one of the chargers like tig| mentioned would also work
[13:16] <Mjolinor> just need to raise hte enthusiasm to turn the soldering iron on now :)
[13:16] <clever> take the 5 volts going into the charger, drop it to 3.3v, and then run it into a gpio
[13:16] <Mjolinor> I need to keep cost really low
[13:16] <SpeedEvil> Mjolinor: you know that you need to balance the cells?
[13:16] <clever> if it vanishes, shutdown
[13:16] * MightyMu (~WHaaaaa@ip68-224-77-19.lv.lv.cox.net) has joined #raspberrypi
[13:16] <Mjolinor> I dont need to balance hte cells
[13:16] <SpeedEvil> Mjolinor: If you don't actively balance the cells - then you need to shutdown around 1V/cell
[13:16] <clever> Mjolinor: let me get what i'm using for something similar
[13:16] <Mjolinor> not using nicads for such a simple task
[13:17] <SpeedEvil> Mjolinor: Series connections of cells need balancing, or you have to accept not being able to discharge them all the way.
[13:17] <Mjolinor> it wil shut down when the supply to the charger goes off, it will never run from the batteries without the batteries being on charge
[13:17] <SpeedEvil> Oh
[13:17] <Mjolinor> they do not need to discharge at all other than the tiem it takes to shutdown
[13:17] <SpeedEvil> You mean it's just to do safe shutdown?
[13:17] <Mjolinor> yes
[13:17] <SpeedEvil> Never mind then.
[13:17] <clever> Mjolinor: part 1, charger/boost, https://www.sparkfun.com/products/11231 $20
[13:18] <Mjolinor> it will be Liion eventually but not while I am developing it
[13:18] <clever> micro usb in, lipo on the side, 5volts out
[13:18] <clever> 2000 mAh can run the pi for 4 hours, but if you only want a clean shutdown *looks*
[13:19] <clever> Mjolinor: https://www.sparkfun.com/products/731 110mAh lipo, not sure exactly, but it should run atleast 5 minutes
[13:19] <Mjolinor> that would do most of what I want but at $20 I can probbaly make 20 for that :)
[13:19] <clever> bigger batterys can always be stuck in instead
[13:19] <clever> $7 for the 5minute lipo
[13:20] <clever> also, these boards are relatively overpriced, if you get the raw parts and assemble it yourself, you can get more savings

[13:20] <Mjolinor> my car camera has one of those really small batteries in
[13:21] <SpeedEvil> If you do, it's likely to not keep the board up for 30s in a year
[13:21] <Mjolinor> that is only for shutdown when you turn the ignition off
[13:21] <clever> https://www.sparkfun.com/products/10718 400mAh lipo, ~30mins maybe?

[13:22] * Adityab (~textual@89.204.153.91) has left #raspberrypi
[13:22] <clever> try different modes on ext3, play with the journal settings
[13:23] <Mjolinor> there isno need really, the raspi iteslf needs attention to prevent corruption so I may as well sovle both problems with a proper shutdown/restart
[13:23] <ShorTie> nicads would be easier to charge, i don't see much need for all the extras just to use lipo's
[13:24] <Mjolinor> in the 3 months I have been doing this I have needed to rewrite he card at least 5 times after removing power without shutdown
[13:24] <clever> Mjolinor: it helps to know WHY you have to rewrite the entire card
[13:24] <clever> what exactly got corrupted that badly?
[13:24] <Mjolinor> nicads will be fine, trickle charge with a current limiting resistor is all they need and 3 diodes to run the raspi, charge hte nicad or run the raspi off battery

[13:25] <Mjolinor> all good fun though :)
[13:25] <Mjolinor> yes
[13:26] <clever> any obvious errors on the display when it failed to boot?
[13:26] <Mjolinor> no
[13:26] <Mjolinor> it actually stuffed a couple of cards
[13:26] <SpeedEvil> You can't safely run the Pi off 4 NiCds at full charge without a regulator of some form.
[13:26] <clever> rainbow of death?
[13:26] <Mjolinor> thats why I am using USB now with the OS on
[13:26] <clever> do you still have some 'dead' cards?
[13:27] <Mjolinor> if you saw this room your wouldnt ask taht question, they will bein here soemwhere
[13:27] <Mjolinor> along wiht everythign else I have pulled apart in the alst 30 years
[13:27] <clever> id say, stick one into a pi and try booting it, and figure out why it failed
[13:27] <clever> if its not even booting, it sounds like os corruption
[13:28] * Mjolinor thinks he should slow down his typing so people do not need an interpreter
[13:28] <clever> mount the rootfs read-only, put the rrd files on a 3rd partition
[13:28] <Mjolinor> I will do that eventually when I have written all the scripts adn C programmes that it needs

[14:56] <dansan> This is a wierd place to ask this, but it's worth a try. Where can I find prototype board with .07 inch pitch? :(
[14:57] <dansan> instead of the normal 1/10th of an inch lead pitch
[14:57] <ReggieUK> farnell probably
[14:57] <ReggieUK> or rs
[14:57] <SpeedEvil> .07 is what - 2mm?
[14:57] <ReggieUK> sounds like it
[14:57] <SpeedEvil> If you actually want a wierd pitch, you could get it made.
[14:58] <SpeedEvil> That would be an excellent gag gift.
[14:58] <SpeedEvil> Some .095" veroboard.
[14:58] <BurtyB> lol
[15:00] <dansan> lmao!!!
[15:00] <dansan> sorry, I had to step away. Nice one SpeedEvil!
[15:01] <dansan> no, .07 inch is 1.78mm
[15:01] <BurtyB> one of my recent "needs" was a wide breadboard but they don't seem to exist :(

[16:30] <Orfeous> i have seen some folks done it
[16:30] <jorick> why is there a linux kernel for the rpi? would it be possible to run a vanilla kernel?
[16:30] <IT_Sean> >_<
[16:30] <jorick> kernel fork*
[16:30] <IT_Sean> Orfeous: Unless you are SERIOUSILY overclocked, you do NOT need heatsinks
[16:30] <nid0> Orfeous: no heatsink is needed whatsoever
[16:30] <InControl> If it needed heatsinks it would have come with them
[16:31] <IT_Sean> ^ that
[16:31] <wbx> jorick: no, vanilla kernel does not support the embedded board (bcm2835)
[16:31] <IT_Sean> the heatsinks you see advertised serve NO purpose save to separate idiots from their money.
[16:31] <BurtyB> :)
[16:32] <jorick> wbx, the embedded board, what does that mean? i lose functionality of the GPIO ports?
[16:32] <wbx> jorick: the basic support for the mainboard + cpu
[16:32] <jorick> oh ok
[16:32] <IT_Sean> jorick: a vanilla kernel would not support the SoC. So... no, not possible at all.
[16:34] <jorick> so as long as i compile the kernel from github, everything works? nothing needed in userland?

[17:38] <raidensnake> debig sumbols?
[17:38] <shiftplusone> in gdb, break main, to set the breakpoint on main, then you can 'step' through and see exactly what's going on.
[17:39] <raidensnake> debug*
[17:39] <shiftplusone> dw, they are probably there.

[17:39] <shiftplusone> but, https://en.wikipedia.org/wiki/Debug_symbol
[17:40] <raidensnake> the main problem is the internal debug for the game itself was disabled due to it being incompatible

[17:40] <Dussed> hey there
[17:41] <jfmherokiller> the internal debug was basicly an ulgy log file

[17:42] <Orfeous> how important is those SD-card speeds for the like raspbian OS?
[17:42] <Orfeous> 20mb/s, 45mb/s etc...
[17:42] <raidensnake> there ain't any break points
[17:42] <shiftplusone> Orfeous, not very.
[17:43] <shiftplusone> raidensnake, set them. For example, 'break main' will set a breakpoint on the 'main' function.
[17:43] <gordonDrogon> if you're interested in my stuff, download RTB and look in screenKeyboard.c. It did take me some time fiddling with the SDL settings to make it work reliably on the Pi.
[17:44] <shiftplusone> raidensnake, this seems like a good intro to gdb http://www.cs.umd.edu/~srhuang/teaching/cmsc212/gdb-tutorial-handout.pdf
[17:44] <shiftplusone> You can also use something like eclipse, which is bloated, but has a decent debugging interface.
[17:45] * aphadke (~Adium@c-71-198-6-18.hsd1.ca.comcast.net) has left #raspberrypi
[17:45] <raidensnake> sorry to say this but I'm totally lost
[17:46] <raidensnake> there's no debugging symbols in the program
[17:46] <shiftplusone> raidensnake, just go through the tutorial I linked
[17:46] <shiftplusone> (add the -g option when compiling)
[17:46] <raidensnake> i would but the server has blocked my provider

[17:49] <Orfeous> 8 or 16gb?
[17:49] <Orfeous> class 10 maybe?
[17:49] <shiftplusone> doesn't matter, whatever you need
[17:50] <shiftplusone> class 10 usually work fine, but some people run into problems when overclocking and using class 10 cards.
[17:50] <shiftplusone> Take a look at http://elinux.org/RPi_SD_cards
[17:50] <Otaku_> Not all cards work with the pi
[17:50] <Otaku_> there is a list somewhere

[17:55] <Orfeous> im very thankful for you that helping me out and not just refer me to some bad Q&A site :)
[17:56] <oddover> google doesn't appear to have any relevant results about it
[17:56] <raidensnake> hey shift
[17:56] <Orfeous> how much space does the raspbian image installed?
[17:57] <shiftplusone> Orfeous, without NOOBS, I think it's about 2GB (just under)
[17:57] <shiftplusone> raidensnake, aye?

[17:58] <shiftplusone> I think you have to learn to use it first
[17:58] <raidensnake> just chucked*
[17:58] <Orfeous> ok so 8gb will do just fine?
[17:59] <raidensnake> well here's the line it gets to when trying to open the window
[17:59] <raidensnake> screen = SDL_SetVideoMode(320, 200, 16, SDL_HWSURFACE | SDL_FULLSCREEN);
[17:59] <shiftplusone> Orfeous, I use 8GB cards and that's enough for me, but make sure you don't use NOOBS.
[17:59] <shiftplusone> raidensnake, on what function call does it fail?
[17:59] <Orfeous> ok, ill keep that in mind

[18:01] <shiftplusone> ah ok
[18:01] <raidensnake> the only thing is it has to be that that's causing the crash
[18:01] <shiftplusone> Does anyone know if you still need to run the bcm functions before using opengl es?
[18:02] <raidensnake> well BCM is loading just fine
[18:02] <shiftplusone> so you have ' bcm_host_init();'?
[18:02] <lee> anybody around who is familiar with ncid in raspbian? and if so, do you know what I have to do to get the ncid-modules installed?
[18:02] <raidensnake> yes
[18:03] <raidensnake> it loads
[18:04] <shiftplusone> raidensnake, I'd need to google around a bit
[18:04] <raidensnake> the hardware itself bcm_host is loading but it's when SDL is trying to set the resolution it's kicking off
[18:05] <shiftplusone> have you tried running with and without X and at different resolutions?

[18:12] <shiftplusone> then you can usually stream the video, if you're playing media, or use vnc if it's just a desktop. (though not over http exactly)
[18:13] <diverdude> basically i made an application now running on an I5...which grabs images from an ethernet camera...puts them in a queue and streams them to clients via http....and also does some processing on the images....its a multithreaded application....i was considering to see if can run on an raspi

[19:58] <clever> yeah, it should have hardware encoders for recording h264 from the camera
[19:58] <clever> it was originaly a phone chip
[19:58] <chithead> what was a phone chip?
[19:58] <clever> just have to feed the decoder back into the encoder
[19:59] <clever> chithead: the main cpu for the pi
[19:59] <johnc-> if the target device is just too dumb to support mkv you could strip the streams from the mkv container and remux them into mp4
[19:59] <johnc-> that would be easier on the pi
[19:59] <clever> then i loose the subtitles
[19:59] <chithead> it appears to me that it was meant for video conferencing and tv stb use, but if you call that phone
[20:00] <clever> chithead: ah, i thought it had heavy signs of mobile use
[20:00] <clever> johnc-: i need to re-encode it to conver the softsub to hardsub

[20:56] <savid> Out of curiosity, would it be theoretically possible to hook up a display from an android tablet to the raspberry pi's DSI port?
[20:57] <savid> I just have an old tablet sitting around doing nothing. Thought it'd be nice to have a portable monitor for the pi.
[20:57] <CeilingKitten> ^ theoretically yes, will it work ? with drivers provided by broadcom maybe one day lol
[20:57] <SpeedEvil> savid: basically, no.
[20:58] <SpeedEvil> The chances of broadcom providing open drivers is regrettably very, very small.
[20:58] <SpeedEvil> In principle, install a VNC client on the tablet.
[20:58] <CeilingKitten> Anyone know of a way to force apt-get to always think i want the suffix --no-install-recommends added to my commands?
[20:59] <savid> SpeedEvil, mostly I'd just want it for debugging purposes when I can't reach it via network
[21:00] <SpeedEvil> Unfortunately, not likely.

[21:38] <clever> odd, my pi cpu is stuck at 2.6 degrees!
[21:38] <clever> wtf?
[21:38] <shiftplusone> stuck how?
[21:38] <clever> the graph has said 2.6 degrees for the last week
[21:38] <Dooley> I have a very stupid question. I am connecting via X ssh to my raspberry. Can I start a graphical application (e.g chromium) and keep control over the shell while the application has started?
[21:38] * soulcake (~soulcake@unaffiliated/soulcake) Quit (Read error: Connection reset by peer)
[21:39] <shiftplusone> Dooley, yes, but you may want to check out a program called 'screen'
[21:39] <clever> shiftplusone: /sys/class/thermal/thermal_zone0/temp says 2600
[21:39] <Dooley> Thanks shiftplusone!
[21:39] <shiftplusone> Dooley, otherwise, start the program you want to start with a & at the end
[21:39] <clever> aha!!, /sys/class/thermal/thermal_zone1/temp has a more reasonable number
[21:39] <clever> ok, why do i have 2 thermal zones?
[21:39] <Dooley> is there any difference between the two?
[21:40] <shiftplusone> so "./myprogram &" will run it in the background
[21:40] <clever> aha, the extra thermal zone is for the battery
[21:40] <clever> which isnt present!
[21:40] <dagerik> shiftplusone: it exits if you exit shell
[21:41] <dagerik> because the shell is owner
[21:41] <shiftplusone> aye, good thing to note, but he didn't say he intends to
[21:42] <shiftplusone> either way, screen is a much better option
[21:42] <shiftplusone> (or tmux if you're of that persuasion)
[21:43] <dagerik> i use screen too. its really nice to have two shells on the pi
[21:43] <clever> CONFIG_TEST_POWER=y
[21:43] <clever> shiftplusone: found my problem :)
[21:43] <dagerik> and not having too ssh to get a new one
[21:43] <clever> shiftplusone: as i suspected, its my custom kernel build
[21:44] <shiftplusone> hm =/

[21:44] * DelphicOkami (~lukosanth@pixie.lukos.co) has joined #raspberrypi
[21:44] <Dooley> I don't want to go over my daily quota
[21:44] <shiftplusone> Dooley, as many as you want
[21:44] <dagerik> go ahead son
[21:44] <Dooley> what's the difference between using screen and starting several instances of putty
[21:45] <shiftplusone> Dooley, if your connection goes down, you can attach back to the screen session
[21:45] <clever> Dooley: screen wont kill the program when you disconnect
[21:45] <clever> and you can view the same output from several systems
[21:45] <shiftplusone> if it's just straight putty, it will terminate everything you had running
[21:45] <shiftplusone> (in that ssh session)
[21:45] <Dooley> aaahhh
[21:45] <clever> for example, this irc client i'm using is inside screen, its been running since sometime in 2012
[21:45] <Dooley> that's amazing, I ndded it without knowing it
[21:45] <clever> over 6 months
[21:46] <dagerik> yeah screen is good for long running processes
[21:46] <shiftplusone> Dooley, aye, and once you learn how customizable it is, it gets better. =D
[21:46] <clever> my laptop has rebooted several times, and the ssh opened and closed countless times
[21:46] <Dooley> I will work on a small weather program to display the forecast on the pi, even when my computer is off
[21:46] <clever> but the irc client never moved
[21:46] <Dooley> I will ahve to start it with screen if I am not mistaken
[21:47] <clever> you can put a script into rc.local to run screen on bootup, and run your thing inside it
[21:47] * rbxs|Zzzz is now known as rbxs
[21:47] <clever> but if you dont need the text output, theres not much point
[21:47] <dagerik> Dooley: there are many ways. e.g. cronjob, disowning the process auto start at boot

[21:56] <shiftplusone> (of the generic monochrome type)

[21:56] <Dooley> How cool is that!
[21:56] <shiftplusone> Why exactly like that =D
[21:57] <clever> shiftplusone: yep, now the temps are reading correctly again
[21:57] <gordonDrogon> then yes, there is something that will drive it. About 120fps too.
[21:57] <clever> my pi is at 50c :)
[21:57] <chod> here also
[21:57] <shiftplusone> clever, what was the exact config option that caused that? O_o
[21:58] <gordonDrogon> I've not documented it yet, but the code is all there in the devLib.
[21:58] <Dooley> mine is at 45C :)
[21:58] <shiftplusone> gordonDrogon, ah, excellent, thanks.
[21:58] <clever> shiftplusone: CONFIG_TEST_POWER=y
[21:58] <clever> shiftplusone: it seems to create a fake battery with a temp of 2.6 degrees
[21:58] <shiftplusone> gordonDrogon, the actual interface is pretty much the same as the character displays, right. Just different commands?
[21:58] <gordonDrogon> https://git.drogon.net/?p=wiringPi;a=blob;f=devLib/lcd128x64.h
[21:58] <clever> and because that loads before the bcm temp driver, my script picks the wrong one
[21:58] <shiftplusone> clever, ah, good to know.
[21:59] <clever> shiftplusone: no idea how it turned itself on
[21:59] <gordonDrogon> shiftplusone, it's completely graphical - not at all like the text ones.
[21:59] <gordonDrogon> I have a simple 8x8 font for it as part of the driver.
[21:59] <clever> shiftplusone: https://github.com/raspberrypi/linux/blob/rpi-3.6.y/drivers/power/test_power.c
[22:00] <clever> shiftplusone: the battery temp is down on line 106
[22:00] <shiftplusone> gordonDrogon, I am only talking about the parallel interface and initialization of them. I have written a small AVR ASM library for a char display, so wondering if they work in a similar way, that's all.
[22:01] <shiftplusone> clever, thanks
[22:02] <clever> shiftplusone: while turning that off, i noticed that the fuel guage i just ordered already has a driver
[22:02] <clever> shiftplusone: https://www.sparkfun.com/products/10617
[22:02] <clever> so once i hook this to the i2c port, i should get proper battery monitoring in linux, with all the standard utils

[22:02] <gordonDrogon> shiftplusone, oh - you poke pixels at it - however you need to poke them 8 bits at a time.
[22:03] <gordonDrogon> so to print a character, you need to poke all the 8x8 pixels to it.
[22:03] <gordonDrogon> Or use a plan B which is to keep a software copy of the buffer then blit it to the display in a single operation.
[22:03] <clever> gordonDrogon: that reminds me, ive seen some crazy things done on sprites mods, *gets link*
[22:04] <clever> gordonDrogon: http://spritesmods.com/?art=spitft
[22:04] <shiftplusone> gordonDrogon, isn't there also a char mode it can enter?
[22:04] <clever> he used the SPI output to drive a shift register
[22:04] <clever> to drive a paralell lcd display
[22:04] <clever> if i remember correctly, the clock line goes into a counter, and after X clocks, it triggers a latch
[22:05] <shiftplusone> ah, looking at your putchar function now, nvrm.
[22:05] <gordonDrogon> shiftplusone, no char mode at all.
[22:07] <shiftplusone> gordonDrogon, thanks for the help. I need to drive one of these with an STM32 board and that's a good reference point.
[22:07] <gordonDrogon> shiftplusone, there're really odd things - actually 2 separate 64x64 chips driving each half of the display.
[22:08] <gordonDrogon> and they're rotated the wrong way - or so it seems.

[22:09] <clever> gordonDrogon: ive seen a teardown of an old lcd driver before, it was single sided and twisting all those data lines would have been a nightmare
[22:10] <clever> so they cut a hole in the pcb, and mounted the entire chip upsidedown, in the hole
[22:10] <shiftplusone> I think I'll try getting it up and running on a pi first to make sure the display itself is fine. I am not sure if it will work with 3.3v =/
[22:10] <clever> flipped it over

[22:10] <gordonDrogon> I have some other drivers for colour LCDs too - with touch screen, but I've not released them yet.
[22:10] <shiftplusone> ah, I have seen something like that on an eevblog teardown as well.
[22:10] <clever> shiftplusone: yep, thats exactly where i saw it
[22:11] <shiftplusone> ah, there you go >_<
[22:12] * IT_Sean has a small LCD he should try to see if he can get to work on a raspi.
[22:12] * IT_Sean has NO documentation on it, however.
[22:12] <shiftplusone> Not a generic one?
[22:13] <IT_Sean> I'll have to check the board for any model identifiers. It was salvaged out of another device, though.
[22:13] <shiftplusone> gordonDrogon, would a 5v display work or would I need to make sure it's a 3.3v one?
[22:13] <Dooley> I read it is possible to split the screen with screen, but I can't get it to work
[22:14] <clever> shiftplusone: depends on if there are any pins that transmit back to the pi
[22:14] <Dooley> the right command is Ctrl-A-shift, ain't it?
[22:14] <clever> Dooley: ctrl+a capitol s
[22:14] <Dooley> thanks again :)
[22:14] <clever> then ctrl+a, tab
[22:15] <clever> ctrl+a Q makes the current one full (closes all other tabs
[22:15] <clever> ctrl+a X closes the current
[22:15] <gordonDrogon> shiftplusone, that display is a 5v one - same as the text display, make sure it can't write - tie r/w to 0v.
[22:15] <clever> ive been using it for years, i can now mash out ctrl+a S ctrl+a 1 ctrl+a tab ctrl+a 2
[22:15] <clever> in an instant
[22:16] <shiftplusone> gordonDrogon, thanks again. Maybe asking a little too much at this stage, but do you have a bit of a schematic of what goes where. I know I can figure it out from the source and the image, but it would be nice if there was a schematic.
[22:17] <gordonDrogon> shiftplusone, sorry - not done one yet...

[22:22] <gordonDrogon> if you have enough RAM on the stm32 board then keep a software copy of the display and update it all at once.
[22:22] <gordonDrogon> otherwise you need to read a byte off the display or/and the bits then write it back again - painful & slow.
[22:22] <gordonDrogon> so I treat the display as write only here.
[22:22] <shiftplusone> I do, but I need it for other things =(
[22:23] <gordonDrogon> I waste 8K bytes on the Pi...
[22:23] <bts__> I would be grateful if somebody checked this simple ASM code: http://pastebin.com/NT1sABQV
[22:23] <Dooley> clever, is there any way to resize my vertical split?
[22:23] <bts__> it's still somehow mysterious for me ;x
[22:23] <gordonDrogon> but you could get it down to 1K if you use 1 bit per pixel - which is what the display is - I was just being lazy using 8bpp.
[22:23] <clever> Dooley: ctrl+a + and -
[22:23] <clever> Dooley: or ctrl+a :resize 20
[22:24] <shiftplusone> heh, fair enough
[22:24] <Dooley> thanks clever, I'll keep coming back and haunt you regarding screen
[22:25] <gordonDrogon> bts__, gave up on asm code years ago. I don't need it anymore. not enough brain cells left..
[22:27] <bts__> gordonDrogon: but is very low-level programming in C easier than in ASM? I doubt :)

[22:36] <gordonDrogon> bts__, well I wrote the digitlaWrite() function.
[22:36] <gordonDrogon> shiftplusone, not sure the cs1/cs2 go to the 2 separate chips. the other pins are commoned (in my display anyway!)
