UPDATED GUIDE: OpenGL-based Games & Emulators on PiTFT Displays (Pi 3 compatible!)
This is exciting…recent releases of the Raspberry Pi’s Raspbian operating system provide support for Adafruit 2.8″ and 2.2″ PiTFT displays “baked right in,” it’s just a matter of some device tree configuration. It’s available in Raspbian Jessie and Jessie Lite 2016-03-18, as well as RetroPie 3.6 (an amazing collection of classic game console and computer emulators). What’s more, these displays now work on the Raspberry Pi 3, so incredibly potent handheld consoles are possible. But if you’re using an earlier Pi, or the diminutive Pi Zero, it’s the exact same setup sequence across the board. Nice!
