Hello. I am using some queues in my project and want to ensure that they work as I expect:
1) When I issue xQueueReceive with wait ticks > 0, I suppose that current task will be suspended (switched) and will not hang unnecessary using the MCU. The “wrong” way is that current task (which issued xQueueReceive) makes blank loop checking for incoming data in queue or task switch. The “right” way is to immediately give control to RTOS and next task and make next queue check when next task switch returns the control.
2) sending/receiving data with queues is thread safe - i.e. it is not necessary to create mutexes to avoid conflicts.
