Project Description

An Netduino Library for the TI TLC5940 16-Channel PWM Chip.


The aim of this project is to create a easy to use driver for the TLC5940 chip to be used on the Netduino .

The Netduino

Netduino is an open source electronics platform using the .NET Micro Framework.

The Chip

The TLC5940 is a 16-channel, constant-current sink LED driver. Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step, constant-current sink (dot correction). The dot correction adjusts the brightness variations between LED channels and other LED drivers. The dot correction data is stored in an integrated EEPROM. Both grayscale control and dot correction are accessible via a serial interface.
