Overview

This reference design describes the implementation of a software controlled RGB LED on an MSP430, using a single timer module and Capture Compare Register.  This design also includes a serial communication interface for externally

Features
  • Red, Green, Blue (RGB) LED control with P-FETs to source LED current directly from VCC
  • Independent control of color and brightness
  • 512 unique colors and 50 brightness levels
  • Software PWM generation uses a single Compare Capture Register on one timer module
  • Serial interface for externally controlling LED
