Button Component
The Button class provides a simple way to read the state of a button. There
are two ways to configure the functionality of the button.
The first uses Button::Config to configure the button to call a function when
the button is pressed or released and uses the Interrupt class' task and ISR
for signaling. At any time, a user may also call the is_pressed method to read
the current state of the button's input pin.
The second uses Button::SimpleConfig to simply configure the button as an
input with configurable pull-up or pull-down resistors and a configurable active
state (high or low). In this configuration, the input is read manually any time
the user calls the is_pressed method.
Example
The example shows how to use the espp::Button class to handle
input events from a physical button connected to an ESP32 GPIO pin.
