Waveshare RP2040 Tiny board arrived and we made a new PCB for it.
I used a PIO state machine for the display’s SPI (converts 565 to 888 during the DMA transfer), so it was easier to route all the pins around the board.
Also added a debug UART which was not present in the previous version. It might be handy if something
goes wrong before the CDC is initialized.
I should now focus on the software part of the project. Most of the stuff are ready. Just a couple of hal pins
to expose and finish the UI.
