RGB matrix isn't working #34

Open Sramsram opened 3 years ago

Sramsram commented 3 years ago

Touch sensor, keypad matrix, humidity sensor, lc display are working fine - any demo app with the RGB matrix doesn't work.

(using CP2 with RPi4 2GB).

Hey there. I ran into the same issue I think. I changed from Rpi 4 4GB rev. 1.1 to rev 1.4 and all the projects including RGB matrix were broken. In some the LCD Display was flashing instead. I opened the Project in Mu, and the Debugger said it was because of an unsupported hardware revision Replacing the older Pi fixed everything. You may check what hardware revision

I hope this can be fixed with a Software update.

The Tech Support from my local Pi-store had the solution: It's just uninstalling and reinstalling the library for the RGB Matrix:

1. sudo pip uninstall rpi_ws281x 2. sudo pip3 uninstall rpi_ws281x 3. sudo pip install rpi_ws281x 4. sudo pip3 install rpi_ws281x
