AZIZ LED Ring Light Firmware

This is the firmware code to control the AZIZ LED light ring. AZIZ is based around an Atmel ATTiny1634 microcontroller, connected to a Texas Instruments TLC59116 constant current LED driver. Sixty four (64) LEDs are arranged in a ring and driven by the driver chip in groups of four. User control is provided via three buttons, three colored LEDs, and two rotary encoder knobs.

Several adjustments are allowed, included brightness, fading, and pattern selection. Forthcoming user documentation will describe modes of operation in more detail.

Code builds in Atmel Studio V6.1 Beta.
