Hi Daniil, My repository is hosted here: https://github.com/ironblock/ST7701S-SPI-Driver
I tried to document the build steps as thoroughly as possible, but please let me know if I’ve missed something or if there are any questions I can answer. I do all my development work in macOS (running Ubuntu in Vagrant), and the target is always a Rev C BeagleBone Black, running the Debian 9.12 ImgTec image from https://beagleboard.org/latest-images I don’t have access to the hardware at this exact moment, but I can check various settings later. I don’t remember if I updated to Debian 10 on that board, but I may have. Unfortunately, the chip shortage kind of paused all my development, but I’m happy to help anyone who can make use of this code. Pull requests, comments, questions welcome ☺️ On Friday, June 18, 2021 at 6:39:38 AM UTC-7 Daniil Savchenko wrote: > Could you share a link to your project?
