Touch

The Touch module allows for certain GPIO pins (P2,P3,P4,P6,P8,P9,P10,P19,P20) to accept capacitive touch inputs. A touch input is similar to a button, except for the lack of mechanical contact. The capacitive nature of touching a pad or pin will trigger a touch event.

Constructor

class machine.touch(pin)

Create a touch object on pin.

Example:

touch = Touch('P9')
touch.read()

Methods

touch.read()

Reads the value of the touch pin

touch.config([sensitivity])

Set the threshold of the touchpad interrupt. Currently not used

touch.init_value()

Currently not implemented
