This is a blog post of someone converting a conventional bit-banged method of driving a display to pure PIO. Maybe it helps getting an idea? https://www.zephra

- jazzyjackson 4y agoIt is, at once, both over my head and very encouraging that someone who hasn’t used PIO before was able to achieve this, thanks for the link, I think if I compare this code to what the Plasma library is doing I might be able to tease out what’s happening.
- _Microft 4y agoDid you have a look at chapter 3 of the Raspberry Pi Pico C SDK already by the way? It's about PIO programming. https://www.raspberrypi.com/documentation/microcontrollers/c_sdk.html#raspberry-pi-pico-cc-sdk https://www.raspberrypi.com/documentation/microcontrollers/c...
- jazzyjackson 4y agoI did not notice they wrote a whole book on the SDK, this looks perfect, thanks again
- _Microft 4y agoThe C SDK contains examples, the actual documentation is in the RP2040 docs. It's also chapter 3. https://www.raspberrypi.com/documentation/microcontrollers/ https://www.raspberrypi.com/documentation/microcontrollers/
