Raspberry Pi Pico 8bit_18bpp PIO source code

[Elrir94]

Hello Bodmer,
I'm trying to write a driver for the the SSD1963 controller to use with the pico-sdk. I was successful in writing one using the GPIO functions, but it's not as fast as the one in your library, I've noticed you've used the PIO of the Pico, I'd like to do the same but, there is no source code for the PIO assembly program. In fact even if I've managed to make it work with a simple PIO, it's slower than the GPIO functions :( and I don't know why. I've been looking in the GitHub repo for the code but I've managed only to find an old file in a commit with only the 8 bit PIO. It would be amazing if you could share the code for the pio_8bit_parallel_18bpp.pio.h file.
Thanks.
Mattia.
