Timer callback as class instance

[glrtheil]

I'm having a really hard time passing an instance of a callback method that's in a class (C++), oto an esp_timer callback. I'm essentially trying to port some code from an old project to ESP and this old project uses a Timer class that allows you to pass in the function and the instance of that class then uses std::bind() to point to the callback method, and that's what gets passed into the Timer. However I seem to be unable to do this with esp_timer, regardless of my attempts.

I've created the esp_timer_create_args_t, and tried passing in any non-static function, but that never works. I even went as far as passing the return of std::bind() as the arg of the timer_args, and calling it within there, but I get an panic abort when I try to call the function.

Is there any simple way to create esp_timer_create_args_t and pass in an instance of a callback function?

This is how I do this.
Especially the callback class is handy.

I think the code is quite straight forward, however if you need some help, do ask.

Wow, thanks so much for that. Looking through it now.

As another reference, you could consider the ESPTimer class from esp-idf-cxx project: https://github.com/espressif/esp-idf-cx ... er_cxx.hpp
