Detailed Description

DigitalInputChange provides output whenever a digital pin changes its state.

DigitalInputChange is triggered by an interrupt on the pin, so it is guaranteed to catch all state changes on the pin. However, output reporting occurs during the ReactESP event loop, so for extremely fast state changes (with a frequency of at least several tens of kHz), it is possible that the event loop can't keep up and only the latest value is processed.)

Parameters

pin	The GPIO pin to which the device is connected
pin_mode	Will be INPUT or INPUT_PULLUP
interrupt_type	Will be RISING, FALLING, or CHANGE
config_path	The path to configure Sensor parameters, if any
