Nov 15 03:07:58 The replicape can handle bipolar stepper motors. Nov 15 03:08:07 as long as you identify the pairs, you should be fine... IIRC, worse case is the motor runs backwards Nov 15 03:08:18 That is what I thought. Nov 15 03:08:28 and never ever disconnect the motor with it powered up Nov 15 03:08:36 It might just run backwards from what direction I thought it would run. Nov 15 03:08:38 Right. Nov 15 03:08:56 I know about connecting/disconnecting w/ the power on. Nov 15 03:09:00 Do not do it! Nov 15 03:10:54 ds2: Thank you for your reply. I just wanted to make sure that plug and play would not destroy my replicape, i.e. not hot plugging. Nov 15 03:36:05 :) Nov 15 03:57:06 is set trying to not blowing things up again? Nov 15 03:58:24 Yes! Nov 15 03:58:45 dude you have to let the smoke out... it needs a walk! Nov 15 03:59:22 Dude? Oh! Dude! Nov 15 04:00:26 I am trying to make this replicape work but for some reason, it is not as easy as I once thought it would be. I blame my motors so far. Nov 15 04:00:48 Hissing comes from my steppers. Nov 15 13:49:54 set_: that means they're angry at you Nov 15 13:50:09 try to apologise to them Nov 15 13:59:11 lol, the MIPI DPI standard is quite a mess... it specifies six different configurations of how the data lines are used, only two of these are compatible with each other ("16-bit configuration 3" is a subset of "18-bit configuration 2"), LCD panels may use any of them, DPI-compliant controllers are required to support all of them... Nov 15 14:00:23 with LCDC and its pixel format quirks you get a whole bunch of different wirings from which you'd need to select the correct one based on the panel interface depth/configuration and the pixel format used for the framebuffer... https://docs.google.com/spreadsheets/d/e/2PACX-1vSlUrBqn1M8obS5eUt1ky7igWEVsqoMstwLifkkBKHGS4s23VqLOodQAyctcCAz-3WEDP2J4_-dJGIS/pubhtml?gid=1877221557&single=true Nov 15 14:02:04 (I've omitted using a 24-bit framebuffer with a 16-bit LCD panel since doing so would be kinda silly) Nov 15 14:06:07 It gives you a great range of mistakes and mis-wiring..... Nov 15 14:06:50 At last, I think I'll go for this... https://www.buydisplay.com/default/tft-5-inch-lcd-display-module-controller-board-serial-i2c-ra8875 Nov 15 14:07:17 easy solution: just wire up all 24 lines arbitrarily and have software permute the bits of each pixel in whatever way is appropriate for the panel ;) Nov 15 14:08:09 to be fair, in practice I think lcd panels often just label their data lines with R/G/B rather than "D" Nov 15 14:09:53 and then the wiring only depends on the color depth of the panel and whether you want a 16-bit RGB565 framebuffer or a 24-bit RGB888 one Nov 15 14:16:12 fred__tv: hmm, they give you the option to select between pin header connection or FFC, but it's not clear whether they're talking about the serial interface, the lcd interface, or both... the image kinda seems to suggest both, but presumably you'd want a pin header connection for the serial interface and ffc for the panel Nov 15 14:17:42 At the end of webpage are all specification and schematics of various options Nov 15 14:18:35 It seems they are configurable via jumpers Nov 15 14:18:40 ehm it's just a matter of a header being placed or not... Nov 15 14:19:10 and the datasheet just specifies for each of the two interface that pin header is an option Nov 15 14:20:07 especially https://www.buydisplay.com/download/interfacing/ER-TFTM050-3_Interfacing.pdf Nov 15 14:20:53 the jumpers are for interface type yeah... they might be solder-jumpers though, if they were physical jumpers there'd be no need to select the option when you buy Nov 15 14:21:58 ehm, that pdf says absolutely nothing about the question I raised Nov 15 14:24:00 ah yes, Nov 15 14:25:13 you can choose between pin header or FCC Nov 15 14:25:13 oh never mind, this is not just a controller but controller + 5" 480x272 display module Nov 15 14:25:40 yes, it's a complete display+interface Nov 15 14:26:35 that costs less than the only Adafruit controller module... Nov 15 14:27:01 There is also the 800x480 version with same controller Nov 16 01:06:41 I was having trouble signing in but a button powered "poweroff" and replug worked. Nov 16 02:09:00 new image! Nov 16 02:30:22 Is anyone using the gps3 install from pip3? Nov 16 02:31:26 https://pastebin.com/JuMfvAQJ is my new error and it seems that things have broken somehow. Nov 16 02:42:49 https://pastebin.com/1swMSyiM <--- also this Nov 16 02:43:04 I fixed the source they goofed up since python2 w/ their comments. Nov 16 02:43:10 But...Same issue. **** ENDING LOGGING AT Sat Nov 16 02:59:57 2019
