Timing
Lightweight, platform agnostic, stackful cooperative threads library
The library is intended to be used on resource constrained platforms where using fully-fledged RTOS would be problematic. Idle related API allows switching the platform to a desired sleep mode and reduce power consumption. Wait/notify support for effective threads synchronization.
Maintainer: Piotr Stolarz
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
