Fix random phantom touches #308

Closed kinafu closed 3 years ago

kinafu commented 3 years ago

There's an error in the parameters passed to the TFT_eSPI_validTouch function which results in some invalid ("phantom") touches if one sets ADATOUCH_PRESS_MIN > 20.

The treshold parameter was set to 20 instead of the ADATOUCH_PRESS_MIN value, which may be set by the user and has default values set to e.g. 200.

Thanks for catching this @kinafu !
