Thank you! Each 8x8 matrix is multiplex by a driver chip called Max6960, so the processor itself does nothing more than update the video memory inside the Max6960 chip when needed. If I remember correctly the Max6960 uses a 20 MHz clock for pwm/multiplexing. You can find more info on this on my homepage (link is in the description).
I would like to do a led pong like that, probably smaller, how much the purchase amount? Is it hard to program for a beginner? Are there tutorials on internet? Anyway thank you for the interesting video ;)
Hi there, I got those 8x8 bicolor led matrices from a company called LC LED, they have a fair price for them, but you can for sure find them on E-bay as well. If you aren't that familiar with electronics and microcontrollers I would suggest you start with something smaller like an 8x8 or 16x16 led matrix. I know there are plenty of tutorials on how to control those on the internet. Thanks for the comment and good luck with your pong game :)
Yepp, this is the first test run of the display. But in the latest revision there is also a gamepad connect to it and the microcontroller now contains tree games, Tetris, Pong and Snake.
Very well done dude, how you getting them to multiplex so fast, what speed is your processor at?

Cool, I also did Tetris, Pong and Snake on a pic 16F877.
I ditched the Pong game since it isn't much fun without arbitrary angles.

Very nice. The large display is great!

What are you using to control it?
biojae 4 years ago
Each 8x8 matris is controlled by a Max6960, and all 12 of them are controlled by a Renesas H8S/2357 microcontroller via a 4-wire SPI bus.
