This is a bit old, but as I’ve not really seen anyone else implement st7586, wanted to share progress.
I have done a framebuffer implementation on a 360x160 2 bpp display (but using 1bpp monochrome fb for now). It works ok, but consumes lots of ram, and is relatively slow to sync (about 230-250ms).
the project with my ugfx fork is here:
https://github.com/zerog2k/rcqr01
I would like to improve this, with such an odd packed pixel format, it doesn’t allow us to write individual pixels horizontally, only in groups of three (so very strange!] So I’m not sure if one way would be to handle each line write by reading the line from controller into row buffer, updating and writing back out. Not sure how to approach this yet, but open to ideas.
