  • 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.
