64x32 RGB LED Matrix - 5mm pitch every other 2 rows blank

Post by peterbrune »

Hey, I'm pretty new with raspberry pi's and connecting them to LED screens.

I'm trying to create this: https://github.com/riffnshred/nhl-led-scoreboard

I have everything set up on the raspberry pi and everything appears to be working except every other 2 rows are blank whenever I run the scoreboard.

Here are the products I'm using:
64x32 RGB LED Matrix - 5mm pitch
Adafruit RGB Matrix Bonnet for Raspberry Pi
Element14 Raspberry Pi 3 B+ Motherboard

Here are some pics of my set up and what is currently going wrong

Someone said that maybe I have a bad Matrix Bonnet? Has anyone else had this issue or know how to fix this? Am I really going to have to buy another Matrix Bonnet even though that might not be the issue?

This looks like a software configuration issue.

Let's backup to the Adafruit guide.

Are you using a 4A power supply?

Is sound disabled?

Did you successfully run the demo?

Code: Select all

sudo ./demo -D0 --led-rows=32 --led-cols=64
