ST7789

This may or may not be of use. It was not done in Micro Python, but it could possibly be adapted.

Raspberry Pi Pico PIO proof of concept, 15M pixels/sec

Out of curiosity, I had a play with this board, https://www.waveshare.com/wiki/Pico-Eval-Board Unfortunately there is a hard speed limit of about 1.5M pixels/sec using 16 bit colors (due to the SPI to parallel conversion circuitry hardware, which maxes out at about 24Mb/s). I am currently running the RP2040 at 267MHz and intend on tweaking the code to use the second core to do flushing, but I doubt it will result in any really meaningful performance improvement. This is not a great performer…
