Hello. I have a Unicornhat but only the top 5 rows out of the 8 light up. When the code runs it seems to think all 8 rows are working as I don’t get any errors, yet the bottom 3 rows stay dark. I’ve tried this on a Pi 4B running Raspbian and also Ubuntu, as well as on a Pi Zero W running Raspbian. In all cases, I’m able to run the example programs in the Github repo but only 5 rows light up and the other 3 are do nothing. I tried telling the code to rotate 90 degrees, which it does, but the 3 rows that were dark before are still dark.
I don’t think this is a case of interference from something else. I’m not playing any sound, I tried removing the sound drivers completely, and I tried plugging in an HDMI monitor. There’s no interference on the LEDs either: they’re all dark when I’m not running the python code and the 5 rows light up perfectly when I run the example code.
If I set the code to think it is a PHAT, the top for rows light up properly.
Has anyone seen this before? I’ve been using a Rainbow hat on my Pi4b and Pi Zero W for a few months now with no issues so I think I’m using the Unicornhat correctly. Maybe it’s defective?
