Drivers for the ST7789 and ST7735 controllers

Hello, I have written a graphics library with drivers for the ST7789 and ST7735 controllers. (In principle, the library can be easily adapted to any controller). The library uses an frame buffer between the graphic primitives and the controller. Changes made in the frame buffer are transmitted to the controller using SPI transfers under DMA. To reduce transfers, the frame buffer is divided into blocks; only the modified blocks are transferred to the screen. The graphic primitives are minimali…
