This is an Arduino Library for the Adafruit 2.2" SPI display.
|
||
This library works with the Adafruit 2.2" TFT Breakout w/SD card
|
||
----> http://www.adafruit.com/products/1480
|
||
|
||
Check out the links above for our tutorials and wiring diagrams
|
||
These displays use SPI to communicate, 4 or 5 pins are required to
|
||
interface (RST is optional)
|
||
Adafruit invests time and resources providing this open source code,
|
||
please support Adafruit and open-source hardware by purchasing
|
