LED Christmas Star

The star is about 35cm across and designed to be displayed indoors in a window.

I originally created the star three years ago using a 16F872 controller. The original version worked ok – but had no spare memory for adding more features.

This new version uses a 18F2620 because I now prefer the 18F series and decided it would be a good general purpose 28 pin chip to use. It has more than enough memory (64K) so I can add as many features as I want now.
