I’m using the example for Brigetek BT81x chip on a Riverdi IoT resistive display.
It works initially fine up to an issue with callibration.
Since the display is a resistive one, the calibration part int eh example has to be uncommented:
After the manual calibration on start the result seems to be everytime very imprecise and the tap on buttons is triggered with an obvious offset.
Did anyone have the same issue?
Any idea how to localize the reason for this issue?
