ESP32 drives a 320x240 TFT display using LittlevGL GUI library. The display module has an ILI9341 controller with SPI interface running at 40 MHz.

LittlevGL is configured to use 2 internal graphics buffers 60 lines each (320 x 60 x 16 bit (2 byte) = 37,5 KB). While LittlevGL draws a part of the content to one buffer, the previous part is flushed to the display form the other buffer in the background using DMA. This way rendering and refreshing of the display is done in parallel.
