Guest Posted December 14, 2010 Report Share Posted December 14, 2010 Hi everybody. This is the first topic I start in this forum. In this topic I'll try to describe as detailed as possible how does an RGB LED Matrix work and explain how to make one. I will be using common ICs and a microcontroller. I will try to divide this topic into two sections: 1.- How RGB LED Matrices work and, 2.- How to make one. Since the first part is somewhat theory, this is very important to understand the second part, and also provides de ability to port the second part to any microcontroller. Right now, I leave some links and documents that were very very useful to me when researching about this: http://www.franksworkshop.com.au/Electronics/RGB/RGB.htm http://blog.littlebirdelectronics.com/moving-forward-with-arduino-chapter-18-rgb-le http://www.ucontrol.com.ar/wiki/index.php?title=Funcionamiento_de_una_matriz_de_LEDs (this one is in spanish, so if you can read it you'll find it very helpful) If you read the whole attached document (Intro to driving LED matrices) you may skip my "First section", because it is based mainly on that document. The second document attached contains a schematic of how a RGB LED matrix is wired, and it may help you to understand how is it posible to drive it with just a few pins.Introduction to Driving LED Matrices.pdfRGB FULL COLOR MATRIX.pdf Quote Link to comment Share on other sites More sharing options...
Guest Posted February 26, 2011 Report Share Posted February 26, 2011 Well. Here I upload the documentation for this project. In this document I explain as detailed as I can, how I developed the project. You will find some references to "Parallax Holiday LED Contest", because I did this project for a this contest. I hope it helps. I am also attaching the code for this project. I used a PIC18F2550 and mikroC to make the code. Anyway, the explanation is very general in the document "Project Report RGB LED Kite". You will notice that I made an RGB LED Matrix and installed it in a kite. http://dl.dropbox.com/u/14406903/Project_Report_RGB_LED_Kite.docx http://dl.dropbox.com/u/14406903/RGB_LED_Kite.c I hope it helps the community.
