RGB Led Matrix, Now with PWM
The controllerboard on the LED RGB Matrix devices from Sparkfun contain an Atmel atmega8 controller and three 74LS595 serial shift registers to control the 64 RGB LEDs. With the default programming the backpack only displays 8 colors (actualy 7, black isn’t realy a color). I wanted to allow more colors. Luckally you can re-program the controllers, so I wrote a new program for the backpacks allowing 4-step PWM on each R/G/B Channel.
You can download the WinAVR files here: avr_rgbmatrix.zip
But this is a blog about the .NET Micro Framework, so I should also upload some C# code, ready for download is a very preliminary program that displays the capabilities of the RGBMatrix class.
You can download the Visual Studio 2008 solution here: MF_RGB_Matrix_EarlyVersion.zip
And finaly a video from Youtube:
