Are FreeRTOS queues safe from multiple writers?

Posted by genarisimo23 on October 23, 2013

I would like to know if FreeRTOS queues are safe from multiple writers tasks. Consider two task having different priorities that write to the same shared queue. Does i need to mutex that queue to be safe?

Thanks for your response!

The queues are completely thread safe and can be read form or written to by any number of tasks. No mutex is required.

Regards.
