FreeRTOS之Tasks和Co-routines的区别

Co-routines使用在对RAM资源少的场合

 

Task Summary

	Simple.
	No restrictions on use.
	Supports full preemption.
	Fully prioritised.
	Each task maintains its own stack resulting in higher RAM usage.
	Re-entrancy must be carefully considered if using preemption.

Co-Routine Summary

	Sharing a stack between co-routines results in much lower RAM usage.
	Cooperative operation makes re-entrancy less of an issue.
	Very portable across architectures.
	Fully prioritised relative to other co-routines, but can always be preempted by tasks if the two are mixed.
	Lack of stack requires special consideration.
	Restrictions on where API calls can be made.
	Co-operative operation only amongst co-routines themselves.
