Keep getting address issues on my 64x32 led matrix #1110

Open skggs opened 3 years ago

Total beginner, trying to build this scoreboard ( https://github.com/riffnshred/nhl-led-scoreboard) and can't seem to get the connection to the matrix right, keep getting address issues. Its an Adafruit led 64x32 screen with a HUB75 port (not hub75e). Ive checked the hardware a dozen times and can't seem to find any issues there. Any help would be appreciated a ton!

What do you mean with "address issues" ? How do you connect the LED matrix (manually, using Adafruit Hat, own adapter ?)

I just get random patterns on my screen when I try to run the sample. I’m using an adafruit hat

hzeller commented 3 years ago

did you choose the hardware mapping for the adafruit hat ?

skggs commented 3 years ago

yeah, so this the exact command I'm running cd nhl-led-scoreboard/submodules/matrix/bindings/python/samples sudo python3 runtext.py --led-rows=32 --led-cols=64 --led-gpio-mapping=adafruit-hat --led-brightness=60

I'd try first the non-Pyhton test programs to reduce the things that can go wrong. Once you get the demo program running, you can move on to testing Python if needed then the scoreboard.

Also make sure to adapt the gpio slowdown settings (might be needed if you run a fast Pi such as the Pi4) and read the troubleshooting section.
