This is a lightweight and fast coroutines implementation designated for small microcontrollers. It is easy portable and fully independent from operating system or platform.
The code bases on best fragments of FreeRTOS and RTThread libraries. The main idea was extraction of coroutine logic and make a simple library for it.
Current implementation supports:
- coroutine priorities
- configuration on compile time
- statically/dynamically allocated objects
- standard coroutine switching methods
- sleep
- yield
- queue type
The code was tested on x86, x64, avr platforms with GCC toolchain.
The library can be configured by uCoroutine/config.h header. Sample configuration file is available in uCoroutine/sample/config.h
uCoroutine uses uCoroutine/platform.h header for getting definitions of platform dependent functions like:
- methods that MUST be defined (and implemented)
uCoroutine_platform_isr_enableuCoroutine_platform_isr_disableuCoroutine_platform_getTicks
- methods used by dynamic allocation
uCoroutine_platform_mallocuCoroutine_platform_free
- methods used by debug submodule
uCoroutine_platform_abortuCoroutine_platform_printf
Sample platform.h header is available at uCoroutine/sample/platform.h
