This is the library for the Adafruit RA8875 Driver board for TFT displays
|
|
---------------> http://www.adafruit.com/products/1590
|
|
The RA8875 is a TFT driver for up to 800x480 dotclock'd displays
|
|
It is tested to work with displays in the Adafruit shop. Other displays
|
|
may need timing adjustments and are not guanteed to work.
