I just bought a Unicorn hat for my brand new Pi Zero and am really excited, I’ve been meaning to play with the Pi for a long time!
I’m posting this because I can’t find a similar issue searching the forums. Everyone either has a Python syntax error or no output at all but I’m getting a sort of corrupted output on mine.
For example running simple.py from my examples folder should cause the LEDS on the hat to turn on and stay on but is instead causing the LEDS to flash at an irregular rate, sometimes just a few in the bottom right (looking at it with the usb out of the pi at the bottom) and sometimes all of them, though the top row never seems to go above half-brightness.
I’m an experienced solderer but I’m worried that I have somehow overheated and damaged my hat. I soldered the pins quickly with a high wattage iron, taking breaks between to let the board cool so I figure it must be one of the following:
- The hat is faulty
- I overheated something beyond repair
- my soldering has a dodgy connection on one or more pins.
I’m hoping an experienced user of the hat can guess at the issue from my symptom description so I can work out whether all is lost or not!
I’ve just gone through with a multimeter and done a continuity check for each GPIO pin between the Pi and the hat with no issues found. There are no pins bridged accidentally by solder.
I’m really looking forward to playing around with this so I’m sort of hoping someone recognises this as a fixable software issue :/
I am using a Raspberry Pi Zero running Raspbian OS.
The Python scripts are being run without syntax errors via SSH terminal.
