In today's mailbag, a 1.28-inch TFT watch built around the @Raspberry_Pi #RP2040 microcontroller, https://www.tindie.com/products/adz1122/pi-pico-rp2040-128-inch-tft-display-watch-board/. Comes with pre-blown firmware, but absolutely no documentation at all. So I guess it's time to try and figure out how they're talking to the screen. First stop `picotool` to poke around inside the firmware, and then more aggressive methods. Although, with a bit of luck, I can find some datasheets for the screen and other peripherals. Fascinating one!
