Touch related IO
touchio module contains classes to provide access to touch IO typically
accelerated by hardware on the onboard microcontroller.
All classes change hardware state and should be deinitialized when they
are no longer needed if the program continues after use. To do so, either
deinit() or use a context manager. See
Lifetime and ContextManagers for more info.
import touchio from board import * touch_pin = touchio.TouchIn(D6) print(touch_pin.value)
This example will initialize the the device, and print the
Read the state of a capacitive touch sensor
import touchio from board import * touch = touchio.TouchIn(A1) while True: if touch.value: print("touched!")
Whether the touch pad is being touched or not. (read-only)
You can adjust
thresholdto make the pin more or less sensitive.
Deinitialises the TouchIn and releases any hardware resources for reuse.
No-op used by Context Managers.
