Jim Carver / Mbed 2 deprecated RGB2

This is a project to replace the 8051 on a existing RGB LED board and add USB functionality. The original board relied on 8051 firmware to control the LEDs so any changes required software development. This version provides a USB interface for LED control. The USB interface is implemented as a HID with a 9 byte OutReport. In conjunction with a simple GUI the RGB LED board can now be controlled to set color patterns, intensity and pattern sequencing.

Dependencies:   PCA9635-6 mbed USBDevice

RGB GUI - Windows program to control the PCA9635 board.
