portENTER_CRITICAL() ------ vTaskSuspendAll()

Posted by Nobody/Anonymous on January 10, 2007
what happens if I change all "portENTER_CRITICAL()" to "vTaskSupendAll()"??
will this be a risk?
the problem is that I don't want to block that many interrupts.

I think you could change some, but not all. The ones in QueueSend and QueueReceive have quite a specific interaction with TaskSuspendAll for example. Also task delete I think would not work. Basically each would have to be looked at in turn. It would not necessarily improve efficiency though. For very short critical sections the enter/exit critical are preferable.

You cannot yield from within a vTaskSupsendAll() vTaskResumeAll() pair. When you do this the yield is pended until the vTaskResumeAll() call.

ok than I think that I will only use it for my functions.
thanks for the fast response!
