@nca78 said in ESP32 based IoT gateway/control hub with TFT, touch, RFM69 and more..: Bodmer TFT eSPI Bodmer TFT eSPI is just a normal SPI driver, well maybe optimized a bit. The key to speed (IMHO) is to use double frame buffer and DMA for the SPI, that leaves the CPU free to process the next frame while the hardware does the SPI transfer. I am not aware of such TFT library for Arduino.
