This is an example 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.
|
||||
|
||||
Adafruit invests time and resources providing this open
|
||||
source code, please support Adafruit and open-source hardware

by purchasing products from Adafruit!
