An Arduino Library for the Texas Instruments TLC5940 16-channel LED Driver.

Installation and Examples

Unzip the Tlc5940_xxx.zip folder into the arduino/libraries/ folder.

Then look at the BasicUse example (File -> Examples -> Tlc5940 -> BasicUse).

News

• Now supports the Teensy board. Also check out http://www.pjrc.com/teensy/td_libs_Tlc5940.html for videos of some of the example sketches.

• Multiplexing (still alpha): Tlc5940Mux_2.zip. Also see http://www.youtube.com/watch?v=U1t9usUr9ns - 3 tlc's drive the entire 8x11 grid, by driving one row at a time and switching through the rows. This is the Serial example in Tlc5940Mux.

• Now supports servos! See the example (Sketchbook->Examples->Library-Tlc5940->Servos) and documentation.
