This driver is for running a daisy chain of Allegro MircoSystems A6281. Th A6281 IC is a three channel, 10-bits per channel LED driver. The Brilldea PolkaDOT product series uses the A6281 LEDs and red, green, blue (RGB) LEDs. More information about PolkaDOTs is available at

Included in the zip file is the driver and a demo of how to use the driver. If you have questions or a recommended improvement, let me know through a PM on the Parallax Forum.
