Tft framebuffer, I am using DMA2D and TFT LCD module of MCU
Tft framebuffer, Apr 27, 2025 · FBTFT serves as a bridge between the Linux framebuffer subsystem and small TFT LCD displays connected via SPI or GPIO interfaces. The touchscreen is calibrated and moves the cursor correctly. The module 'fbtft' makes writing drivers for some of these displays very easy. It also highlights some hardware, software, and architectural considerations to obtain the best graphical performances. This unit implements the shared functionality that is common to all devices and provides a set of functions that device specific drivers must implement. I've got something that works, but since I am drawing so many lines at weird angles I'm not efficiently using SPI transfers to get data on the screen. git clone https://github.
