Brad from Brads Electronic Projects shows us how to make 8 RGB LEDs create a large circular display. He uses a spread sheet to create the HEX data that the PIC microcontroller will be using to turn on the RGB LEDs to make the system display what you would like but the display data is stored on an EPROM to allow for large moving displays. Reminds me a bit of my POV Display that I made many moons ago, only thing is that Brad’s is about 100 times better.
