Description


The Adafruit PiTFT 3.5" LCD is a 480 x 320 pixel TFT with resistive touchscreen using a Himax HX8357 driver and a STMicroelectronics STMPE811 resistive touchscreen controller.

This unit ties together the various components needed to make one of these boards work with Ultibo by finding the correct SPI device, creating the STMPE811 Touch device, creating the HX8357D Framebuffer device and registering all of it with the correct parameters for the Adafruit board.
