Purchased Automation Hat mini last week and completed code dev on a Pi 2. Examples and my code work fine.
Moved the Hat mini to a Pi Zero W and the examples worked once but now display is blank and no errors thrown from the code.
When Hat mini moved back to Pi 2 display works ?
Any ideas on what to try to fault find this.
Check the header soldering on the Zero maybe?
Thanks Pete - it defo a connector issue as slight movement of the pcb causes patterns on the display. I purchased a solderless header - GPIO Hammer Header (Solderless) - Pimoroni which is the cause.
That will be it then; I wish they’d stop selling those headers, it seems to be incredibly hard to get a reliable connection with them :-(
