[0:51] <chars6> hey, i was just on #xbian looking for help. i'm gonna copy/paste my first few questions
[0:51] <chars6> about 2 weeks ago i came home and my RPi2 seemed broken
[0:51] * cave (~various@h081217073183.dyn.cm.kabsi.at) Quit (Remote host closed the connection)
[0:51] <chars6> i'd get alternating flashing red and green lights, so i ordered another one
[0:52] <chars6> he new one comes in the mail today, i load XBian on a microsd card and plug it in
[0:52] <chars6> and my tv reads no signal, with the RPi having a flashing green light
[0:52] <chars6> so now i think... maybe it was the sd card? i flash a new microsd and try that. same flashing green with no signal
[0:52] <chars6> thing is, i have a RPi1 which works fine using all the same cables
[0:52] * brethil (~brethil@2.236.134.159) Quit (Quit: Quits existence)
[0:52] <chars6> and before i plugged in the newest RPi2, i tried it one last time and instead of alternating red and green i was only getting green, like the new one is doing
[0:54] <chars6> in summary, that's 2 RPi2's not working, (green blinking ACT led) and 1 RPi1 works fine, same everything
[0:54] <NedScott> Are you using the Pi2-specific image?
[0:54] * brethil (~brethil@2.236.134.159) has joined #raspberrypi
[0:55] <chars6> soemthing else i just noticed a mintue ago, with the RPi2's. if i plug them in without an sd card, the new one does nothing different, just same green blink, but the old one, after a few blinks, gives me a steady red and green led
[0:56] <chars6> NedScott: yea, i think earlier i got the wrong version trying to download the latest, but since then i've been using an old img i had saved from before
[0:58] <chars6> i have 2 microsd cards. the one i was using before my first RPi2 "broke" (not too sure about that anymore) and a fresh one i just opened today. different manufacturers
[0:59] * Encrypt (~Chuck-nor@AMontsouris-553-1-34-16.w92-151.abo.wanadoo.fr) Quit (Quit: Quitte)
[1:00] <chars6> oh, turns out the broken one doesn't stop at a steady red/green when i turn it on without an sd card, it does other weird blinking shit afterwards
[1:01] <chars6> i tried installing OpenElec too. same issues
[1:02] <NedScott> weird
[1:05] * pppingme (~pppingme@unaffiliated/pppingme) has joined #raspberrypi
[1:06] * bizarro_1 (~bizarro_1@146.Red-88-14-185.dynamicIP.rima-tde.net) Quit (Quit: Leaving)

[1:17] * mgottschlag (~quassel@reactos/tester/phoenix64) Quit (Ping timeout: 260 seconds)
[1:18] <lee> I have a (low bandwidth, keypad) I2C device that I want to have a reasonable distance away from the Pi (maybe two metres), what physical cable would you use? CAT6? cut up a serial cable?
[1:19] * zacdev (~zacdev@unaffiliated/zacdev) has joined #raspberrypi
[1:19] <Kamilion> chars6: and you've tried the most recent rasbian images from may, I think it was?
[1:20] * Hoerie (~Hoerie@535480BF.cm-6-5c.dynamic.ziggo.nl) has joined #raspberrypi
[1:20] <Kamilion> I assume it was working at one point, as you describe returning to find it 'broken'.
[1:20] * jatb (~jatb@199.127.226.210) has joined #raspberrypi
[1:20] * Kaboon (~Kaboon@524A74DE.cm-4-3b.dynamic.ziggo.nl) has joined #raspberrypi
[1:21] <Kamilion> have you tried a different power adapter? (Making an assumption here that you overloaded your powerbrick for a bit too long and one of the solder joints weakened or something)
[1:21] * gyaresu (~gyaresu@unaffiliated/gyaresu) Quit (Max SendQ exceeded)
[1:21] <chars6> Kamilion: i've tried XBian and OpenElec so far
[1:22] <Kamilion> I got a pi2 not too long ago and was messing with uboot for a while, so I've gotten a bit familiar with it's behavior
[1:22] <chars6> Kamilion: the adapter i was using was .7A i swapped it out for a 2A one and no difference. i did only try it once though and i forget the specifics of which OS/sd card i was using
[1:23] <Kamilion> yeah, -- I was using a samsung phone charger
[1:23] <Kamilion> had all kinds of weird problems
[1:23] <Kamilion> went and bought a 10 watt power brick from centralcomputers for $10 and all the problems went away
[1:23] <Kamilion> says 2.1 amps on one port and 1 amp on the other
[1:23] <chars6> Kamilion: from what i have read, ACT led deals with sd card problems, but i don't see an entry anywhere for what continuously blinks green means
[1:24] <Kamilion> though I'm pretty sure it's just a 3A 5V switching regulator
[1:24] * bigmac88 (~bigmac88@static-173-55-241-99.lsanca.fios.verizon.net) Quit (Ping timeout: 256 seconds)
[1:24] * gyaresu (~gyaresu@unaffiliated/gyaresu) has joined #raspberrypi
[1:24] <Kamilion> so you're seeing the GPU wiggle some pins there as it goes through it's bootloader
[1:25] <Kamilion> and that's correct -- normally when it can't find the SD or something, it blinks a few times, goes solid for about two seconds, then goes out and doens't come back until it's power cycled.
[1:25] <chars6> Kamilion: i'm downloading latest raspbian right now
[1:25] <Kamilion> so the blinking is probably indicating some kind of internal problem, which doesn't sound good
[1:26] <chars6> yeah, if i don't figure this out by tomorrow i guess i return it
[1:26] <Kamilion> got anything to do power monitoring?
[1:26] <chars6> i'm not sure what broke the last one. i was away for a few days and the power went off. everything else i own survived though
[1:26] <chars6> Kamilion: not really
[1:26] <Kamilion> ahhhhhh
[1:27] <Kamilion> Hm. You should be on hydroelectric power up there
[1:27] <chars6> i have 3 now. the original version 1, then my old 2 and the 2 i got in the mail today
[1:27] <Kamilion> which is normally pretty tightly regulated
[1:27] * bugzc_ (~bugzc@unaffiliated/bugzc) has joined #raspberrypi
[1:28] <chars6> Kamilion: no, it was some renovation in the apt above me that killed the electricity
[1:28] <Kamilion> Hm... breakers getting flipped shouldn't toast anything normally
[1:28] <Kamilion> and something like that normally doesn't cause a surge on reconnect
[1:29] * Berg (~chatzilla@pa122-110-74-165.pa.nsw.optusnet.com.au) has joined #raspberrypi
[1:29] <chars6> Kamilion: plus, i turn it off by unplugging it half the time anyway
[1:29] <Kamilion> got it on a surge protected power strip, at least?
[1:29] <chars6> how many amps should the power adapter put out, ideally?
[1:29] <Kamilion> those things are really only good for lightning strikes
[1:29] <chars6> yeah, it's on a surge protector
[1:29] <Kamilion> so, there's a couple specs there
[1:30] <Kamilion> USB 1.1 and 2.0 specify 500ma
[1:30] <Kamilion> apple went and did some magic with the inner two data pins being pulled to some paticular value with resistors
[1:30] <Kamilion> which signals 1A and 2.1A availability
[1:30] <Kamilion> other manufacuturers followed suit like samsung
[1:30] * andatche (~andatche@mule.andatche.com) Quit (Ping timeout: 252 seconds)
[1:31] * emulator_ (~emulator_@ip70-190-214-210.ph.ph.cox.net) Quit (Ping timeout: 264 seconds)
[1:31] <Kamilion> so far as I know, 2.1A is probably the spec you want, and as it's easily found as 'ipad charger', it's common to run across everywhere.
[1:31] <Kamilion> but, uh, if you really want a brute
[1:32] <chars6> Kamilion: wait.. is this for the pi1 or pi2? https://www.raspberrypi.org/downloads/raspbian/
[1:32] <Kamilion> http://www.amazon.com/Anker-Desktop-Charger-PowerIQ-Technology/dp/B00GTGETFG <--- everyone I've gotten these for has loved them and refuses to give them up
[1:33] <Kamilion> chars6: Both, it contains a pi2 kernel as well as a pi1 kernel, and the rootfs is built for a pi1's armv6, which the armv7 in the pi2 has no issues with executing.
[1:33] <chars6> Kamilion: oh, nice
[1:33] <Kamilion> it's really the kernel that's doing the work, on a pi2, the CPU spec is new enough to meet most distro's minimum requirements of an ARM7.
[1:33] <chars6> that's handy
[1:33] <Kamilion> the pi1 did not, that's why rasbian's around
[1:33] <Kamilion> a build for the arm6 specifically.
[1:34] <Berg> i use something similar to this from this aussie stor http://www.bunnings.com.au/deta-single-power-point-with-dual-usb-charger_p4331192
[1:34] <Kamilion> also why you see a lot of arch being used
[1:34] * dansan (~daniel@76-215-41-237.lightspeed.ftwotx.sbcglobal.net) has joined #raspberrypi
[1:34] * andatche (~andatche@mule.andatche.com) has joined #raspberrypi
[1:34] <Berg> hi im berg and i eat mango's from my tree you can see from space
[1:35] <Kamilion> chars6: the more annoying thing is that most of the big distros that have ARM builds have an arm7 minimum requirement. Like ubuntu. So, the pi1 won't run any of the ubuntu images...
[1:35] <Kamilion> https://ubuntu-mate.org/raspberry-pi/ <--- but the pi2 runs them fine. :)
[1:36] * Syliss (~Syliss@dpncorp1.digitalpath.net) Quit (Quit: Syliss)
[1:36] <Kamilion> there's probably a bunch of RPM based distros too, but I don't like RPM so I don't track them at all.

[1:39] * {0xc6} (~c6h@unaffiliated/c6h) Quit (Quit: Eternity beckons.)
[1:40] <chars6> Kamilion: yeah, i found that page. it just keeps blinking green at a steady pace
[1:41] <chars6> raspbian is done, about to write the image
[1:41] <Kamilion> http://www.amazon.com/gp/product/B00S2HJAUE/ <--- I highly suggest having something like this around
[1:41] <chars6> i looked for the Micron logo, couldnt find it

[1:48] <mattrichardson> Should any HDMI switch work for switching a monitor between my MacBook Pro and Raspberry Pi?
[1:48] <mattrichardson> Looks like some are just 1080p, so I guess not.
[1:49] <Kamilion> anything that's hdmi 1.2a compliant
[1:49] * darkbasic (~quassel@niko.linuxsystems.it) Quit (Ping timeout: 250 seconds)
[1:49] <Kamilion> I'd suggest the monoprice switchers.
[1:49] <Kamilion> they have one or two "3D/4K" switchers
[1:50] <chars6> i think i ran dd on a non-existing file and i'm too scared to cancel it
[1:50] <mattrichardson> thanks Kamilion
[1:50] <mattrichardson> It would throw up an error if you did it on a non-existing file
[1:51] <chars6> mattrichardson: yeah, that's the thing. i tab autocompleted, but i don't see the file in that directory
[1:51] * breakingmatter (~breakingm@8.29.138.28) has joined #raspberrypi
[1:51] <Kamilion> mattrichardson: I've got their 4x2 matrix switcher and it's been lovely, but I'm only doing 1200p
[1:51] <chars6> mattrichardson: hmm, it shows up from ls in the terminal, just not in the GUI file browser
[1:51] <Kamilion> f5 to reload the view?
[1:51] <chars6> Kamilion: i tried that
[1:52] <chars6> i'll just let it finish and see what happens
[1:52] <chars6> maybe, say if it isn't done in another 10 mins, cancel te command
[1:52] <mattrichardson> Kamilion thanks for the reco. I'll check it out.
[1:53] <Kamilion> http://www.monoprice.com/Product?p_id=6415
[1:53] <Kamilion> I think this is the good one
[1:55] * nakasi (~nakasi@unaffiliated/nakasi) Quit (Remote host closed the connection)
[1:55] * breakingmatter (~breakingm@8.29.138.28) Quit (Ping timeout: 255 seconds)
[1:56] <Kamilion> http://www.monoprice.com/Product?p_id=5312 <--- and this is the one I have.
[1:56] <Kamilion> I like it cause it can be controlled from a serial port.
[1:58] <Kamilion> http://www.monoprice.com/Product?p_id=6166 <--- also cause they sell replacement remotes for like $2
[1:58] <mattrichardson> Kamilion thanks again. I'm wondering how my laptop would behave with it. I presume if I switch the input away from the laptop, it would be seen by the laptop as unplugging (so it would move all my windows to the main screen).
[1:59] <Kamilion> nope, ONLY if you assign the input to the second output
[1:59] <mattrichardson> Kamilion OK, good to know.
[1:59] <Kamilion> then the display EDID changes and windows freaks out and redetects everything
[2:00] <Kamilion> the box will clone the EDID of the monitor on each output when it powers up
[2:00] <mattrichardson> I guess they thought of my very concern.
[2:00] <Kamilion> this is important to note because if you disconnect the monitors and connect other ones without a power cycle, everything freaks out
[2:00] <mattrichardson> That totally makes sense.
[2:01] <Kamilion> yeah, there's been a specification in monitors since the VGA ports to dedicate two pins, one for 5V100ma power, the other for i2c communication. In practice, there's a 512 byte rom chip in every monitor that contains the table of resolutions it supports, called the EDID, Enhanced Display Identification
[2:02] <Kamilion> your pi also does this too
[2:02] <chars6> nope. trying out raspbian did not help. i'll have to return this pi
[2:02] <Kamilion> chars6: sucks. better luck with the next one.
[2:03] <chars6> Kamilion: yeah, thanks for trying
[2:03] <Kamilion> because of that 5V pin on VGA/HDMI, the rom chip in the monitor can be 'active' even when the rest of the display isn't plugged into power at all.
[2:04] <Kamilion> and the PC still knows 'I have a samsung SDH3000-2034b connected on HDMI2 supporting 720P'
[2:04] <mattrichardson> Kamilion Ah! OK, that totally makes sense. I wondered about that before.
[2:05] <Kamilion> there's also a neat trick you can do to PCs if you don't want to plug in a monitor and it won't start up without one
[2:05] <Kamilion> one of those little rom chips costs about 15 cents, and a VGA connector with pins is about a dollar.
[2:06] * wiiguy (~fake@unaffiliated/wiiguy) Quit (Quit: The Kirito is always right foundation. Grand reopening)
[2:06] <Kamilion> you can use a raspberry pi to program an EDID table into the chip, wire three pins to the VGA shell, and instant fake monitor.
[2:06] <Kamilion> lots of people need something like this when they do 3D rendering on a bunch of PCs at home, for instance
[2:06] * EastLight (~n@90.209.104.28) Quit (Remote host closed the connection)
[2:06] <Kamilion> they sell commercial things that do this on ebay and amazon for between $20 and $100
[2:07] <Kamilion> because nobody realizes how simple it actually is. :)
[2:07] <mattrichardson> Good trick to know!
[2:07] <Kamilion> http://www.amazon.com/CompuLab-4K-Display-Emulator-fit-Headless/dp/B00JKFTYA8/
[2:08] <Kamilion> here's one of the less expensive ones that says it supports high resolutions.
[2:08] <Kamilion> Great for remote desktop

[2:08] * HtheB (~HtheB@sd5111184.adsl.online.nl) Quit ()
[2:09] <Kamilion> so the trick with windows remote desktop -- set up autologin so the computer gets to the desktop (with a real 3D GPU backing Aero) then remote desktop and join that session with remote desktop. All the 3D programs will still work.
[2:10] <Kamilion> if you just leave the PC sitting at the login screen and try to use remote desktop, it will make a new 'fake' desktop without a GPU behind it
[2:10] <Kamilion> and then kick you off when the person at the PC tries to log in
[2:10] <Kamilion> Computer quirks, man. I tell ya.
[2:10] * Kamilion wipes off his brow in an exaggerated motion
[2:11] <Kamilion> incendentally, if you want to use your pi as a really fast remote desktop client, you'd have to do the above to get good performance on like youtube and games and stuff.

[3:18] <Flynnn> abnormal: ahh, darn
[3:18] <Flynnn> right, here's my problem:
[3:18] <Flynnn> when I supply exactly 5v, the raspberry pi refuses to boot up
[3:18] <Flynnn> well, sometimes it boots up
[3:19] <Flynnn> but the red light flickers and it turns on and off
[3:19] <abnormal> how are you feeding the supply?
[3:19] <Flynnn> through breadboard, which is probably why I'm losing some voltage
[3:19] * Screak42 (~Screak42@79.97.221.233) Quit (Ping timeout: 272 seconds)
[3:19] <abnormal> yes, not a wise way to do it
[3:20] <Flynnn> so I'm gonna need to solder up a direct power unit, and plug that into my 12V supply?
[3:20] <abnormal> always get the correct PSU for the pi.. always...
[3:20] <abnormal> no, 12 V will fry the pi

[3:21] <Flynnn> only way to do it
[3:21] <Flynnn> this is an embedded project
[3:22] <abnormal> I see... then you need niston
[3:22] <Flynnn> no keyboard, mouse, anything, just i2c, ethernet, and power
[3:22] <Flynnn> what is niston?

[3:23] <Flynnn> I'm gonna try directly connecting my pi to 5v not through the breadboard

[3:23] <abnormal> wise decision
[3:23] <Flynnn> well I can't do it permanently
[3:23] <Flynnn> I'm just gonna find out what the actual cutoff voltage is for stability
[3:25] <Flynnn> weird thing is that the whole system used to work
[3:25] <abnormal> well, the pi only needs 700mA, but you need to supply it alone... (no interference from outside supplies)
[3:25] <Flynnn> but I was probably getting lucky with marginal voltages
[3:25] <Flynnn> oh, hmm, I have a multitude of other devices on the same 5v supply

[3:29] <abnormal> one of my pi's has a piface hat.
[3:29] <Flynnn> so, it must be the breadboard
[3:29] <Flynnn> that or other devices
[3:29] <abnormal> yes

[3:31] <abnormal> if it was me, I'd get the piface to protect the pi
[3:31] <Flynnn> not to mention, the DCDC converter has filter caps
[3:31] <abnormal> or the Gertboard
[3:31] <Flynnn> so any kind of noise in the line should be dealt with

[3:33] <abnormal> and will brick the pi
[3:33] <WACOMalt> Hey, anyone currently using the wolfson audio card on a Pi2? I cant seem to get it to work
[3:33] <abnormal> oh you bought one?
[3:33] <WACOMalt> yeah
[3:34] <Flynnn> are you talking about overdraw, noise, reverse voltage?
[3:34] <abnormal> ok you need to do the apt-get update, WACOMalt
[3:34] <Flynnn> I mean, I suppose that these chips could frack with my switching regulator, though I hope not
[3:34] <WACOMalt> oh ok
[3:34] <abnormal> yeh, Flynnn
[3:34] <WACOMalt> it will detect it and get what it needs automatically?
[3:34] <Flynnn> it's got signal filtering, so, it should be good on that front
[3:35] <abnormal> yes, WACOMalt
[3:35] <abnormal> ok, Flynnn
[3:35] <abnormal> just be very careful, Flynnn
[3:35] <Flynnn> Reverse voltage is impossible, noise is not going to do anything the raspberrypi doesn't cause, only thing I am at risk for is overdraw, but I believe I selected the right max current draw

[3:36] <abnormal> I am not there to observe what you are doing.
[3:36] <sasha> Hai, having a bit of a problem with how my Pi interoperates with physics
[3:36] <sasha> When I hook up a switch like this (http://raspi.tv/wp-content/uploads/2013/07/RasPi.TV-RPi.GPIO-input-output1_bb-1024x746.png), it keeps the switch always pushed/closed

[3:43] <Flynnn> oh, you specifically set it to pullup mode
[3:43] <sasha> oh
[3:43] <sasha> well I just copied some code from somewhere
[3:43] <Flynnn> the circuit shouldn't work at all in pullup mode
[3:43] <Flynnn> when you disconnect your pulldown resistor, it should go unresponsive
[3:43] <Flynnn> can you try that for me real quick?
[3:44] <sasha> when I disconnect the 10k resistor, it goes unresponsive
[3:44] * breakingmatter (~breakingm@8.29.138.28) Quit (Ping timeout: 252 seconds)
[3:44] <Flynnn> good
[3:44] <Flynnn> very very good
[3:45] <Flynnn> okay, just making sure we aren't breaking the laws of physics hehe
[3:45] <sasha> hehe
[3:45] <Flynnn> keep your resistor removed and just change "GPIO.PUD_UP" to GPIO.PUD_DOWN"
[3:45] <Flynnn> that'll fix your circuit
[3:45] <Flynnn> or, it should, anyways
[3:45] <sasha> nop
[3:46] <Flynnn> awe
[3:46] <sasha> Tried it both with and without the 10k resistor
[3:46] <sasha> But is it that horrible to use it without resistors?
[3:46] <Flynnn> it won't work at all without resistors
[3:46] <sasha> Well empirical evidence proved otherwise
[3:46] <Flynnn> you are interpreting the evidence wrong
[3:46] <Flynnn> there are always resistors
[3:47] <Flynnn> they are just usually builtin
[3:47] <sasha> hmm
[3:47] <Flynnn> I actually *want* you to remove the resistor and change the builtin resistor to pullup mode
[3:47] <Flynnn> can you please make a new diagram of your circuit without the 10k resistor, and show me your updated code?
[3:48] * nicdev (user@2600:3c03::f03c:91ff:fedf:4986) has joined #raspberrypi
[3:49] <sasha> interesting
[3:49] <Flynnn> now, if you are working with integrated circuits, resistors often aren't needed
[3:49] <sasha> this works http://sprunge.us/dWDh without the 10k resistor
[3:49] <sasha> (note the change from false to true)
[3:50] <Flynnn> change the true back to false
[3:50] <Flynnn> you'll see it still responds
[3:50] * Syliss (~Syliss@c-24-23-6-50.hsd1.ca.comcast.net) Quit (Quit: Syliss)
[3:50] <Flynnn> it just notices when the button is up instead of down
[3:50] <Flynnn> otherwise, that code should work!
[3:50] <Flynnn> since you have GPIO.PUD_DOWN, it is now using its builtin pulldown resistor
[3:51] <sasha> but do I still need the 1k resistor?
[3:51] <Flynnn> weeeelllll
[3:51] <Flynnn> I don't know actually
[3:51] <Flynnn> depends on the equivalent circuit diagram of GPIO pins one sec
[3:51] <Flynnn> http://www.mosaic-industries.com/embedded-systems/_media/microcontroller-projects/raspberry-pi/raspberry-pi-circuit-gpio-input-pins.png
[3:52] <Flynnn> hmm, never noticed there was hysteresis on that, I'll have to try it out
[3:52] <Flynnn> yes, you want to keep your resistor, there are no series resistors in that
[3:52] <Flynnn> now, it might be using FET technology, in which case the resistors aren't needed
[3:52] <Flynnn> but if it's using TTL, then no resistor will fry your everything
[3:52] <sasha> ok, and so now the 10k resistor is definitely not needed?
[3:53] <Flynnn> it *is* needed, but it's builtin :)
[3:53] <Flynnn> so, the real answer is, no, not needed
[3:53] <Flynnn> specifically, you don't need to add it yourself
[3:53] <Flynnn> raspberry pi already adds it
[3:53] <sasha> So, 1k = needed, 10k = not needed
[3:53] <sasha> Is this correct?
[3:53] <Flynnn> yes
[3:53] <sasha> Wünderbar
[3:53] <sasha> And is this safe for productionish use?
[3:53] <Flynnn> the 1k is needed in series to prevent over-current to your input pin.
[3:54] <Flynnn> and, I mean, honestly, the likelihood of RPi using TTL is slim
[3:54] <Flynnn> in fact, actually, it can;t possibly be using TTL
[3:54] <sasha> By that I mean I won't have pull requests with people telling me how stupid I am for wiring something this way
[3:54] <Flynnn> if it were using TTL, then you wouldn't need the pull down
[3:54] <Flynnn> I think you can get away with not having the resistor there
[3:54] <Flynnn> (the 1k)
[3:55] <Flynnn> I don't know which would be viewed as stupid, not having a resistor, or having one
[3:55] <Flynnn> might even depend on the electrical engineer you talk to
[3:55] <sasha> So tldr of last 20 minutes: yes and no
[3:55] <Flynnn> pretty much
[3:56] <Flynnn> 10k tldr: Actually yes, but with programming, no.
[3:56] <Flynnn> 1k tldr: technically not, but good practice is debatable
[3:56] <sasha> So with my current programming it's a no?
[3:56] <sasha> Ok I'll leave it in then
[3:56] * damianw (~textual@c-68-61-5-66.hsd1.mi.comcast.net) has joined #raspberrypi

[4:05] <abnormal> oh ooooo
[4:05] <abnormal> sorry
[4:06] <WACOMalt> which means I'm out $50+
[4:06] <WACOMalt> sonuva... youd think that would be on the TOP of the product description... not the bottom
[4:06] <abnormal> send it to me and I'll give yo the funds
[4:06] <WACOMalt> yeah?
[4:06] <WACOMalt> I thought the consistent GPIO pins on all models were the same pins?
[4:06] <abnormal> told you there was two models of that board
[4:07] <abnormal> no
[4:07] <WACOMalt> I can only find one wolfson
[4:07] <WACOMalt> there's some Cirrus logic and some others
[4:07] <abnormal> look in the forums
[4:08] <Flynnn> I love how the raspberry pi 2 is still "on sale" for 35
[4:08] <abnormal> somewhere in the pi forums shows the pin layout difference... then you can compare.
[4:08] <abnormal> lol
[4:08] <abnormal> me too
[4:08] <abnormal> lol
[4:09] <WACOMalt> would this work if I were to reorder and resolder the header?
[4:09] <WACOMalt> or is this a lost cause
[4:09] <abnormal> it's a lost cause if you removed the header.
[4:09] <Flynnn> WacoMalt: well, you still need to get drivers, etc
[4:09] <Flynnn> and it sounds like you are having issues with that bit
[4:10] <WACOMalt> well I'm probably having issues with the whole thing. pinout is different
[4:10] <WACOMalt> screw it. I'll just cut my losses and overnight a PiDAC+
[4:10] <Flynnn> as opposed to this fancy audio driver?
[4:10] <WACOMalt> I do regret paying the fastest possible shipping overseas for the wolfson T_T
[4:11] <abnormal> wow......... sorry
[4:11] <Flynnn> yikes :(
[4:11] <WACOMalt> Flynnn, eh?
[4:11] <Flynnn> wolfson
[4:11] <Flynnn> your next message answered my question
[4:11] <WACOMalt> I mean. if its feasible to make this one work... without re building the whole board
[4:12] <WACOMalt> but I think it really isnt an option
[4:12] <Flynnn> well, just thinking about the effort involved in that
[4:12] <Flynnn> how much is the pidac+?
[4:12] <WACOMalt> $50
[4:12] <Flynnn> with or without shipping?
[4:12] <WACOMalt> without
[4:13] <Flynnn> damn
[4:13] <WACOMalt> Looks like the wolfson one got bought out by Cirrus logic
[4:13] <WACOMalt> and that new board is the new wolfson basically
[4:13] <WACOMalt> for B+ and Pi2
[4:13] <Flynnn> okay, so
[4:13] <Flynnn> for $50, you get:
[4:13] <Flynnn> Updated board which is *known* to be compatible with latest technology, and likely has a far more active userbase online for help
[4:14] <WACOMalt> which one is that? the Cirrus?
[4:14] <Flynnn> wait, what? oh dear
[4:14] <Flynnn> what I am trying to say is this:
[4:14] <Flynnn> is $50 worth the effort you will likely put in to fix this wolfson
[4:14] <Flynnn> especially if the wolfson is outdated tech
[4:15] <WACOMalt> well, knowing my skill it would be a lost cause anyways
[4:15] <WACOMalt> I'll just see if I can get a return. if not.. whatever
[4:15] <abnormal> send it to me.. I have use for it
[4:15] <Flynnn> not al ost cause, a learning experience :) but if you are not confident in this thing, then it will take you probably many days
[4:15] <Flynnn> and, it may or may not be possible without months of work, depending upon driver compatibility

[16:43] <breakingmatter> So I've seen some projects before where people remove the LCDs from various devices and rewire them so they can connect to RPI's/Arduinos/etc. Anyone know how they do that?

[16:47] <shiftplusone> breakingmatter: you need to know stuff in order to do that... stuff that you wouldn't be asking about if you knew it. Basically what controller those LCDs have and whether the device you're interested in is able to talk to that controller.
[16:48] <breakingmatter> That's what I'm asking.. How can they know the details of those controllers are if they weren't involved in the manufacturing?
[16:48] <JK-47> looking at part number or product spec sheets
[16:50] <shiftplusone> indeed... it's often a pain to try to find out.
[16:50] <shiftplusone> A mix of google and a little bit of reverse engineering
[16:50] <breakingmatter> Is that information generally available? I mean, I don't feel like spec sheets would normally be floating around for, say, the Kindle e-ink screen
[16:51] <shiftplusone> Do you have a link to where someone uses the kindle e-ink screen without having the kindle talk to it itself?
[16:52] * Natch (~Natch@h-155-122.a444.priv.bahnhof.se) has joined #raspberrypi
[16:52] <breakingmatter> No, I've never found one that didn't use the USB connection. I was just using it as an example.
[16:53] <breakingmatter> I've seen videos for the PSP screen with the RPI, and was just curious why it isn't common to see people reuse screens like the Kindle's
[16:53] <shiftplusone> Well, there you go. I didn't say that you can get all the info about every screen. That's where reverse engineering comes in.
[16:53] <breakingmatter> I understand there can be differences in the hardware of the screen controller itself.
[16:54] <breakingmatter> Oh okay
[16:54] * seriema (~seriema@84-55-80-171.customers.ownit.se) has joined #raspberrypi
[16:54] <shiftplusone> But quite often you can look at the pcb and find a controller part number, google it and find that it's an SPI thing you can just talk to relatively easily
[16:54] <shiftplusone> like the pitft screens
[16:54] <nid0> if you're using something as well known as a kindle you could readily get the part number by googling "*product* teardown", ifixit et al commonly rip new consumer devices like that down as soon as theyre released and publish a full parts list
[16:56] <shiftplusone> not that you're guaranteed to be able to find a publicly accessible datasheet though.
[16:56] <shiftplusone> plus most screens would probably be lvds and very difficult to hook up to a pi (impossible for most people)

[20:17] <Apocx> I never had any issues getting the RF24 stuff working, but then again I didn't use the RFNetwork class
[20:18] <freezevee> Apocx: I did
[20:18] <freezevee> the rpi seems to send packets

[20:18] <Apocx> hm
[20:18] <freezevee> but you see the packets are being send
[20:18] <freezevee> sent*
[20:18] <eni23> is there any release date for raspian jessie?
[20:18] <Apocx> is the arduino receiving valid data from the rpi?
[20:18] <Apocx> like have you looked at the packet data

[20:19] <freezevee> the communication fails
[20:19] <freezevee> Apocx: so there is communication but something else fails
[20:19] <Apocx> so it says "Received packet" yes?
[20:19] <Apocx> on the arduino side
[20:20] <freezevee> Apocx: I don't remember exactly to be honest
[20:20] <freezevee> yes on the arduino side
[20:20] <Apocx> it should say Received packet on one line, then the key, then ------------------------, then going to sleep, etc.
[20:20] <Apocx> based on the code you linked
[20:21] <freezevee> I am talking about the helloworld examples you said
[20:21] <freezevee> in the code I linked yes
[20:21] <Apocx> ah ok
[20:21] <freezevee> I would wonder that my connections aren't right but I triple checked them
[20:21] <eni23> shiftplusone: thx, i allready upgraded to jessie but it kinda feels like a frankendebian now
[20:21] <freezevee> and also I am getting the configuration when printDetails()
[20:21] <Apocx> if the arduino is receiving anything then they're probably right

[21:35] <KittenTheEpic> isn't the RPi 2 the first one to HAVE it?\
[21:37] <nid0> maybe i'm thinking of a different device that used to suffer from it, the whole xenon-flash-switching-the-device-off problem is something I came across somewhere 2-3 years ago, i'd associated it with the original pi b
[21:37] <shiftplusone> KittenTheEpic: you have a lot of xenon flashes around?
[21:37] <KittenTheEpic> no
[21:38] <monsti> it's no bug - they used a cheap version of a chip and didn't protect it from some sort of light

[21:39] <shiftplusone> more of an oversight, I guess, heh.
[21:39] <b3nn1> the rpi ist not that expensive that I would care about a new rpi after I bought the old one
[21:39] <monsti> some transistors also "suffer" from that issue if you remove the protections - but it's no bug
[21:40] <b3nn1> and as soon as there is a new one, it wont have such a huge support like guides

[22:12] <SyncYourDogmas> freezevee: send me a .pcap file?
[22:12] <traeak> yes but there's no protection
[22:13] <b3nn1> no protection means?
[22:13] <freezevee> SyncYourDogmas: from wireshark ?
[22:13] <SyncYourDogmas> Make sure no passwords etc
[22:13] <superbia> so is it safer to just find an old microusb cable, cut it in half, and solder my 5V on red, and ground on black wire, and than just connect that to microusb port of the pi ?
[22:13] <SyncYourDogmas> Or TCP dump

[22:19] <eni23> superbia: yupp. or you solder a wire directly behind the microusb port, then you have protection
[22:19] <superbia> eni23: nah, i just am asking about the microusb
[22:19] <superbia> do i need to make something with D- D+ lines
[22:19] <superbia> on the microusb cable
[22:20] <Apocx> no you just need power
[22:20] <superbia> or just provide 5v and 0V ?
[22:20] <b3nn1> still asking myself what kind of protection is added by the port
[22:20] <superbia> sweet, also does pi have smoothing, reverse voltage protection ?
[22:20] <superbia> in case i drink too much coronas
[22:20] <SyncYourDogmas> There is a dissector for nRF24
[22:20] <Apocx> there are fuses and such when you put power through the microUSB
[22:21] <Apocx> if you go through GPIO it bypasses them
[22:21] <superbia> is there a schematic you have bookmarked ?
[22:21] <SyncYourDogmas> Raw packets will do though
[22:21] <b3nn1> http://i.stack.imgur.com/T5bRL.png
[22:21] <b3nn1> I wanted to wire it like that
[22:21] <Apocx> honestly I think more boards should have VIN/GND for power supplies on their GPIO, with power protection
[22:21] <eni23> superbia: just power it with an smartphone charger which has about 2a...

[22:22] <superbia> so that i can buy psu cheaper

[22:22] <b3nn1> like amazon basic for 8€
[22:22] <superbia> what is a goot vendor?
[22:22] <superbia> i also need to shop locally
[22:22] <b3nn1> as long it it says 5V/2A it should be fine
[22:22] <b3nn1> +as
[22:26] <eni23> superbia: i never saw my pis use more than 1200ma alltough, so 1,5 should be fine too..

[22:31] <shauno> they're not, no. https://www.adafruit.com/datasheets/pi2schem.pdf
[22:31] <shauno> they're probably soldered simply for structural reasons, but they're not connected to anything
[22:32] <eni23> https://www.raspberrypi.org/wp-content/uploads/2011/11/gerbers2.png no...
[22:32] <superbia> sweet thanks
[22:34] <b3nn1> can a breadboard handle 3V/3A (9W)?
[22:35] <superbia> is samsungs 5.3v 2a over the limit ?
[22:35] <superbia> b3nn1: it cant
[22:35] <superbia> look the amps, not volts
[22:35] <superbia> and 3a is a hella lot of current
