Wiring can't be wrong since it's a hat.
The GPIO error message is normal at the first manual start as stopping the autostarted process is ahrd cancel leaving the GPIO's in use (if you ctrl-C and start the box again it won't show up anymore).
The LCD routine is started without error messages.
So for now as I'm as puzzled as well
..did you leave "USE_HD44780_16x2_LCD = False" as is (=False)
Noek
Thank you for your fast answer.
Yeah, it is set to false. I tried different variants. Will include my configuration.txt bellow
UPD:
The manufacturer sent me the pinout, but i can't see anything wrong. They use 3,3V, 5V, GNG, SDA, SCL and also added the pinout image, will attach it also if it helps
UPD2:
On the manufacturers github they mentioned
Quote:This library is based on the CircuitPython_LCD library by dhalbert. The changes were necessary because of a different pinout used with the PCF8574 and a HD44780.Could this be the source of the problem?
