Palettes:
This is a 8x8 demo of palette work with FAB_LED, usin very little RAM.
Parallelism:
FAB_LED can also update LED strips on up to 6 ports in parallel. Updating them
at the same time means you can keep fast refresh rates and yet have plenty
of time to calculate your effects. This is achieved on a 16MHz Arduino Uno.
See ws2812b8s in example F. Note: the 6 ports must be the same letter.
The library also does 2 ports in parallel that can be any port, any letter.
Getting the library:
Thanks for looking.
