The Light Emitting Diode (LED) is a highly efficiency light source, normally controlled by pulse width modulation (PWM) with intelligent environment condition sensing. While the connection between the control center and LED devices could be wireless or cable-connected, the power lines always have cables, and the signaling cable could be bundled with the power cables. Given a large number of fixed devices and a medium distance between devices, DMX512 physical signaling could serve as an appropriate good protocol for the control system. This paper proposes a method to implement a multi-color (RGB) LED programmable control system on chip for increased flexibility and scalability. The implementation comprises a command set architecture customized for RGB-color LEDs, composed of setup, action and query commands, and includes a special visible method to indicate device ID.
