Artifacts using 64x32 LED Matrix w/adafruit RGB Matrix HAT

Post by bmoore26 »

Hi all,

I have an Adafruit 64x32 LED Matrix (4mm pitch), a Adafruit RGB Matrix HAT (https://www.adafruit.com/product/2345), a Raspberry Pi B+ and a 5v 4W power supply.

I have everything wired up correctly (i think) the matrix responds and I am able to display text and images. However, my issue is that rows of LEDs flicker, almost like a bad refresh rate. You can see the video of the issue here: http://tinyurl.com/pt67son and attached.

Any ideas on what I could do to remove the flicker?

TIA

Are there any intensive processes running in the background? Also, has the Pi been overclocked at all?

Some amount of flicker is inevitable (due to the multitasking nature of the system), but that does look a little excessive.
