/******************************************************************
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!
