Hello Henry,

I am currently working with an EVE3-50A-BLM-TPN-F32 Display. I want to operate it using an STM32F429ZIT6, and so far, the only library containing the functions mentioned in the programming guide I found was in the GitHub repo for the STM Demo Code, and some of the functions seem to be missing there. Could you provide a link to the complete library of functions mentioned in the programming guide?

Hello,

while I am not Henry or working for Matrix Orbital, my library is feature complete: https://github.com/RudolphRiedel/FT800-FT813
And I adapted it to the latest changes.

While there is STM32 support, initialization of the SPI and pins need to be provided.
And I have not implemented DMA support so far as I am not really using STM32 controllers for anything.
