Light emitting diode driver and method

摘要

Disclosed is a method and apparatus for controlling a plurality of Light Emitting Diodes (LEDs). A communications protocol is also provided, which comprises a START code, a first Command packet and at least one subsequent Command packet. An LED driver receives a signal according to the protocol, and separates the first Command packet from the signal and controls an LED associated with the LED driver in accordance with instructions in the first Command packet. The LED driver then outputs the remaining signal for use by one or more subsequent LED drivers.
