Description
The Adafruit PiTFT 2.8" LCD is a 320 x 240 pixel TFT with resistive touchscreen using an ILITEK ILI9340 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 ILI9340 Framebuffer device and registering all of it with the correct parameters for the Adafruit board.
