Pleased to hear you have the display sorted.

you won’t get a voltage reading unless your development board has a voltage monitor fitted. Or maybe is used another pin, some do. If not you’d need to fit an external voltage divider that feeds a suitable pin to attach an ADC channel to, just change the readAnalog line and the pin number
