Description
|
|
-----------
|
|
|
|
Touch pin support for ESP32.
|
|
|
|
The ESP32 does have support for 10 touch pads.
|
|
Such a touch pad can be as simple as a wire or a PCB pad connected to
|
|
one of the GPIO pins labelled with ``T0`` ... ``T9``.
|
|
|
|
A touch pad pin can be considered as an analog input pin.
|
|
When not touched, the reported value is "High", for example 100.
|
|
|
|
When touched, the capacity of the pin increases, which in return lowers the number of charge/discharge cycles.
|
|
A typical value for a touched pin is lower than 20.
|
|
|
|
The user has to set a threshold value for when to consider a pin being touched.
|
|
The best value has to be determined by trial and error and may differ per use case.
