TeensyRA8876-GFX-Common

A universal RA8876 graphics library for use with SPI and 8080 drivers for Teensy boards and variants.

Communication with the Teensy is accomplished using a 3/4 wire interface.

This library is designed for use with one of the following RA8876 drivers:

• https://github.com/wwatson4506/TeensyRA8876-8080 or:
• https://github.com/wwatson4506/TeensyRA8876-SPI
