Weird display glitches with 64x64 LED Matrix

Post by ericbr12 »

Hi!

I recently purchased a 64x64 LED Matrix (https://www.adafruit.com/product/5362) along with a SmartMatrix controller and Teensy 4.0.

When I run the demos, if I display a sufficient amount of red pixels, the display "tears" and glitches. Green and blue display just fine.

I have the matrix connected to a 4A power brick, so I don't think it's a power issue.

Any ideas on what's going wrong?

Thanks,
Eric

Make sure that the wires connecting the LED matrix to the SmartMatrix controller are firmly connected and properly aligned. Check for any loose or disconnected wires.Even if the power supply you are using is rated for 4A, it may not be delivering enough current to the LED matrix. Try using a different power supply or a higher-rated power supply to see if that solves the issue.

I double checked the wiring and the soldering. I’m still getting the glitches:
