big LED matrix project update


This gallery contains 4 photos.

Here some photos from the LED matrix. All LEDs wired up now to the drive circuit. 8 controllers run at once! Next thing is to replace the defective LEDs- quite a few. Then I want to try double buffering. But this does not require many new wires. It is however some effort to write the software for this. There will … Continue reading

working at 32×24 LED matrix, PIC 16f59

Working at my LED matrix. 768 LEDs! 32×24 pixels. I want to write a 3D graphics demo. There are electrical issues. The display drive did not work correctly and during 3 days I was not able to figure out what’s wrong. So I removed all of the ICs + replaced with more advanced technology. I use a 16f59 microcontroller now … Continue reading
