[03:27:22] <tmpvar> is there a goto lib for usb-serial for chips with onboard usb controllers (atmega32u4)?
[03:29:33] <Tom_itx> LUFA
[06:43:10] <Hfuy> Hello.
[06:43:25] <Hfuy> I have a recurring problem with AVR Studio 4 - it locks up shortly after loading any project.
[06:43:50] <Hfuy> Happens maybe 75% of the time and can only be cleared by a reboot, but I can't find out what it's running in the background that - presumably - is causing the problem.
[06:45:42] <Hfuy> It's not the programmer as I can disconnect that and the problem persists.
[06:47:25] <Hfuy> Hm. Reboot cleared it.
[07:03:51] <Hfuy> OK, next problem: the input pin appears to be clamping the output of my (active-low) infrared demodulator to ground.
[07:04:24] <Hfuy> I'm using PB3 to read the IR, and the only DDRB reference in the whole program is DDRB = 1 << PB4, since i need 4 as an output.
[07:04:26] <Hfuy> What gives?
[12:54:23] <OSterver> damnit, I can not use 256Mbit 16bit SDRAM
[12:54:37] <OSterver> because it has got single byte addresation
[12:54:41] <OSterver> and I can not simply unhook A0
[12:54:49] <OSterver> because it is used for SET OPTIONS command
[12:54:52] <OSterver> and for column addressing
[12:54:56] <OSterver> damnit!
[12:55:13] <specing> lol
[12:55:17] <OSterver> 256Mbit 16bit costs about 2€, 128Mbit 8bit costs 4.2€
[12:55:17] <specing> ARM, told ya
[12:55:22] <OSterver> heh
[12:55:41] <OndraSter> no more hiding for now
[12:56:22] <specing> ARM ARM ARM ARM ARMARMARM ARM ARM
[12:56:26] <specing> :D
[12:56:37] <specing> even though the chip costs 2 eur more, it pays off
[12:57:05] <Tom_L> ARMadillo
[12:58:14] <specing> ARMageddon
[12:58:42] <specing> ARMada
[12:58:50] <specing> So many words on ARM :D
[13:49:49] <Amadiro> specing, say what
[13:50:05] <Amadiro> Although I prefer to leave out the "r"...
[13:51:29] <specing> Arrrr ;)
[13:53:56] <izua> talk like a pirate day was two days ago
[13:54:32] <specing> ARRRRRRRRRRRRRRRRRRR!
[13:54:51] <Steffanx> and izua always follows the masses?
[13:57:04] <izua> Steffanx: what, you don't accept christmas presents because everybody does?
[13:57:32] <Steffanx> No, i'm not into christmas and presents at all
[14:02:37] <RikusW> megal0maniac: hi
[14:03:12] <RikusW> megal0maniac: R8 is quite cheap :)
[14:03:33] <dioioib> the car?
[14:05:43] <RikusW> ZAR8 South African currency
[14:09:42] <RikusW> seems the thunderstorm is causing a slow connection.... :-/
[14:11:32] <specing> RikusW: I have this book that has instructions on setting up a dialup server
[14:11:37] <specing> :D
[14:11:43] <specing> (you get the hint)
[14:11:58] <RikusW> how will that help me ? manual exchanges don't support dialup....
[14:12:35] <RikusW> seriously, we still have manual exchanges
[14:13:36] <RikusW> but all the copper telephone wires have been stolen.....
[14:13:42] <RikusW> time and again
[14:13:42] <RikusW> so Telkom just gave up replacing them
[14:13:44] <RikusW> seems the manual exchanges will finally be phased out this year or the next
[14:21:04] <AR_> i am DTF
[14:21:22] <Essobi> RikusW: .... you have manual exchanges? Like the physical phone operater plugging in a line?
[14:21:57] <AR_> we do here
[14:28:00] <RikusW> Essobi: exactly
[14:29:54] <RikusW> my connection is really acting down tonight.... must be due to the weather....
[14:31:49] <Essobi> RikusW: Aww.. I hoped you meant a crossbar. :D I was going to drop you some bluebox tones.
[15:58:32] <Vutral> mhm
[15:59:23] <Vutral> hi
[16:13:58] <megal0maniac> Anyone here ever work with a freescale GT16 or similar?
[16:15:34] <Vutral> mhm
[16:15:41] <Vutral> atmega328p can run at 20mhz ?
[16:15:43] <Vutral> *G*
[16:15:59] <Vutral> i wondered if i read the datasheet
[16:16:13] <Vutral> it suggests if leaving clkdiv/8 enabled or so you could use crystals which are usually out of the range
[16:16:17] <Vutral> no idea
[16:16:28] <Vutral> usually i would think a higher frequency crystal got a smaller error
[16:16:32] <megal0maniac> Vutral: As long as Vin is > 4V5
[16:16:46] <megal0maniac> But 20mhz is within spec
[16:16:56] <Vutral> mhm
[16:17:06] <Vutral> well everything in circuit is 5 volt
[16:17:18] <Vutral> and if my isp would be 5 volt tolerant
[16:17:22] <Vutral> i could leave it connected
[16:17:31] <Vutral> so i have to switch between working circuit and programming lol
[16:17:36] <Vutral> a bit annoying
[17:03:15] <megal0maniac> This looks pretty cool... http://www.mikroe.com/mikroc/avr/
[17:07:38] <Roklobsta> yeah only $249
[17:07:48] <Roklobsta> so much cheaper than oh, studio 6
[17:08:16] <Roklobsta> o wow they added a welcome screen
[17:14:28] <megal0maniac> Roklobsta: I kinda ignored the price. Since I won't be buying it anyway :)
[17:14:44] <megal0maniac> They have some nice hardware as well. Not terribly priced
[17:17:40] <Roklobsta> but you will be using it..?
[17:18:33] <megal0maniac> Probably not. It's just cool to see something different. I've downloaded the demo, will try it out tomorrow
[17:18:48] <megal0maniac> Only limit (afaik) is the program size.
[17:22:58] <megal0maniac> It looks shiny. I like shiny :)
[17:23:01] <megal0maniac> Goodnight
[17:54:11] <OndraSter> Atmel, y u no sample board layout for external SDRAM :P
[17:54:14] <OndraSter> the pins are too messy!
[17:54:24] <OndraSter> the easiest way will be to put the SDRAM on the bottom while keeping the MCU on the top
[17:54:34] <OndraSter> otherwise the pins cross around too much
[17:57:10] <OndraSter> how do they do it in the factories with double loaded boards? When they put it into the oven for the 2nd time the bottom parts don't fall out.
[17:57:12] <OndraSter> how?!
[17:58:03] <AR_> simple
[17:59:27] <Tom_itx> glue
[18:01:22] <Tom_itx> and surface tension
[18:13:12] <OndraSter> Tom_itx, do they really glue it?
[18:13:21] <OndraSter> one would think they have better way
[18:21:01] <Tom_itx> i think on some things they do
[18:22:10] <Tom_itx> likely why eagle etc have glue layers
