LCD is doable, it would just take you more time and research to come up with stable cheap solution. LCD are driven by AC at rather pedestrian frequencies, nothing an RP2040 (rp pico) couldnt handle.

- winrid 2y agoYeah you could do it. I'm sure I will at some point be replacing the guts in some devices with STM32s or RP2040 as you said. Or beef it up with ESP32 :) but if the display itself is damaged, that's tough, pretty much just reuse the case at that point I bet.
- rasz 2y agoI meant use rp2040 to tap into raw signals meant for glass LCD in devices using microcontrollers with integrated LCD driver. Interpret and redraw into new framebuffer, spew out to modern LCD/OLED/VGA/hdmi. Replace old custom unobtanium cracked LCD with modern LCD/OLED.
- winrid 2y agooh yeah, that's also a good idea! If they're using the software I sell to organizers it supports regular old computer display out, too, so you could just replace the display board and use HDMI directly these days.
