8/3/2026 - 8th Update!

9:20 PM, let’s go

ok, figure 23 on page 25 of this raspberry pi documentation seems good, did a bit of research, seems that pcm is better than pwm here for audio use cases, with the tradeoff of requiring more electronics

ok, so its like 11:16 PM, here’s the progess! audio thing and sd card thing should both be done, need to look into how to program them (and to verify that its correct), but seems nice so far! still need to work on the display stuff, might also add some leds, quick commit!

ok, back at 11:57 PM (as in, i took a bit of a break), time to do the display and leds (maybe? idk)

ok, everythings looking good! still need to check if the spi for the displays are correct, but now we also need to consider how we’re gonna do the communication between the rp2040s! 1:03 AM, gonna take a second to rest, quick commit!

ok, its a bit later now, i think im gonna end today here, decent progress, really need to finish the schematic and start layout tomorrow!

yeah! that said, it’s 1:48 AM, so good night!
