rgb_lcd_hat/README.md

![demo gif](docs/demo.gif)

This is a hat for the 40pin GPIO headered Raspberry PIs that exposes the RGB LCD interface
in such a way to make it usable with a (albait very specific) lcd screen with touch screen.

Touch screen support is implemented with the AR1100 over a USB cable, which must be plugged to the RPI seperatly. 

For the Backlight a small constant LED driver is on board as well, which can be dimmed by 
using a the hardware PWM1 with GPIO19.
