Hello all fellow electronics enthusiasts! I have a burning question which I can not answer by myself, even after looking through some older posts with a similar titles here on AAC forums. I really need Your help, and will apreciate any tips, advices and ideas!
I am planning to build a small, very low-resolution, 8x8 RGB LED display, which would be able to display a video (some kind of colorful visualization, lo-res) from PC via DVI or HDMI cable and USB. I chose this size because I want it to be more like a prototype, which, if successful, would become a much much bigger display, but that's for the future..
I have around 100 common cathode RGB LEDs lying around, so I would like to use them instead of buying an already made RGB LED matrix.
End goal will be to build a much bigger screen (RGB LED wall), composed of many smaller RGB LED modules, which will be able to display high resolution videos and images from PC.
Now, I am looking for information concerning :
1. Full overview of similar systems and schematics.
2. What separate components are needed to make such system work? Meaning, do I need to use RGB LED drivers and if so, what kind? What about DVI/HDMI video decoders? I do know that I will need a microprocessor to run and control all the other parts, but then again, I am not sure which to choose? PIC, ATmega, Raspberry Pi or even an Arduino board?
3. Similar projects and documentation. If You did or do know that someone else did such project successfully, please post links with helpful info so I could research them!
Any help will be appreciated!
