button

Button handler, with software debounce logic and long-press support.

Internally, it is using interrupts and esp_timer for debounce. Does not poll state when idle, only while button is being pressed (this is necessary, as it is impossible to disambiguate press and release in an interrupt routine).

Usage

To reference this library by your project, add it as git submodule, using command

git submodule add https://github.com/mdvorak/esp-button.git components/button

and include either of the header files

#include <button.h>

For full example, see button_example_main.c.

Configure example application with

cd example/
idf.py menuconfig
