26 : RGB LED Matrix Driver
- Author: Matt M
- Description: Drives a simple animation on SparkFun's RGB LED 8x8 matrix backpack
- GitHub repository
- Clock: 6250 Hz
How it works
Implements an SPI master to drive an animation with overlapping green/blue waves and a moving white diagonal. Some 7-segment wires are used for a 'sanity check' animation.
How to test
Wire accordingly and use a clock up to 12.5 KHz. Asynchronous reset is synchronized to the clock.
