How-to: Make a Serial Controlled RGB LED PWM Driver
Posted By: Vishal Dwivedi | Nov 28 2006
It is simple to build a multiple RGB LED display controlled from your PC or a dedicated controller. For this, you need certain electronic components and basic knowledge of electronics. The provided firmware will run on the following PIC chips: 12F629, 12F675 and 12F683. You need a simple Red/Green/Blue Pulse Width Modulation LED driver that has a serial interface.
The controller driver presented here makes it possible to connect multiple drivers to the same serial cable, which provides them with the same data with synchronized output.
Once designed, it can be controlled from the serial COM port of a PC or using a small-dedicated controller. For detailed information visit the link provided.
