**** BEGIN LOGGING AT Thu Jul 21 02:59:58 2016 Jul 21 13:59:06 Okay, stupid question time: Is there anywhere a quick-and-sane guide to which GPIOs are "safe" to use without worrying about boot-mode confusion? I know better than to use the boot-mode pins for external switches, but I'm having trouble finding a list of which pins to avoid, exactly.. Jul 21 14:03:16 The SRM for the BBGreen isn't too useful but I assume the boot pins are the same as the BBBlack. Jul 21 14:33:59 myself: https://goo.gl/Jkcg0w Jul 21 14:34:21 myself: check the P8 tab there, the essential boot pins are highlighted in eye-stabbing yellow Jul 21 14:35:34 the other sysboot pins should not actually be relevant for the boot mode(s) used by the beaglebone... e.g. the bus width selection for xip/nand isn't relevant since no xip/nand boot is used at all Jul 21 14:36:07 ooh, thanks Jul 21 14:47:46 "eye stabbing yellow": #ffff00 ? Jul 21 14:51:40 myself: o/ Long see no time... Jul 21 14:54:03 Now all we need is a user named yourself Jul 21 14:54:43 Then I could (hypothetically, if it were factual) tell people I talk to my self and yourself all time Jul 21 15:03:30 Ragnorok: hey, ltns :) I've been around freenode, just not doing beaglish things.. heh. Jul 21 15:04:12 Or Arduino-ish. Or is this a different myself? (grin) Jul 21 15:04:24 Same one, check nickserv! Jul 21 15:04:32 Wut? (grin) Jul 21 15:55:05 If I'm gonna use internal pullup or internal pulldown to read a bunch of pushbuttons, is there any preference for which? I feel like there's a bit of CMOS trivia here but I don't know it. Jul 21 15:57:15 I've always thought pullup are preferred because it's "safer" to ground a pin than apply voltage to it. If it's Vcc that's likely moot, but there it is. Jul 21 15:59:08 Yeah, I'd rather have a ground bus snaking around the switch panel, and the only power up there being "soft" through a resistor. good call. Jul 21 17:14:19 Hi Everyone Jul 21 17:14:34 i Using my Beaglebone With simulinkj embedded coder Jul 21 17:15:09 if i use Analog input ports the code gets interruptet each second for one execution Jul 21 17:15:34 how fast is it possible to measure with the analog inputs? Jul 21 17:38:23 I get this problem if i use 4 Analog inputs Jul 21 17:38:34 With 3 in parallel it works fine Jul 21 18:25:03 Daniel_1901: https://github.com/pgmmpk/beaglebone_pru_adc Jul 21 18:25:49 "Oscilloscope mode" does a series of samples on one channel really fast, but does not parallise well (at least with my coding skills) Jul 21 18:26:36 "Basic mode" takes one sample from each channel as simultaneously as possible afaik, but you might get lag between samples Jul 21 18:28:03 I think I saw something like 250 kHz mentioned as top samplerate somewhere, but I've not verified that in any reliable way. Jul 21 21:00:02 ojousima: Thanks for your answer Jul 21 23:31:20 can anyone help with an issue installing debian on a black? **** ENDING LOGGING AT Fri Jul 22 02:59:58 2016
