PiTFT 2.8″ Touchscreen Display is a mini display for Raspberry Pi designed by Adafruit. It features a 2.8″ display with 320×240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Today, I will share the basic steps to start with PiTFT.
