This technical video explains how to scale and rotate a framebuffer on the RP2350 using DMA and PIO.
The code can be found here: github.com/fcipaq/picoengine
There is little documentation as of yet. Some documentation can be found
in the older GitHub repository, github.com/fcipaq/picohero_pplib, which shares a lot of the code.
Many thanks to github.com/ZuluSCSI for the idea on how to do 8-bit
lookups using DMA and the PIO. (This is necessary for paletted
color mode).
