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. RE: portENTER_CRITICAL() ------ vTaskSuspendAll()Posted by Nobody/Anonymous on January 10, 2007 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. RE: portENTER_CRITICAL() ------ vTaskSuspendAll()Posted by embeddedc on January 10, 2007 You cannot yield from within a vTaskSupsendAll() vTaskResumeAll() pair. When you do this the yield is pended until the vTaskResumeAll() call. RE: portENTER_CRITICAL() ------ vTaskSuspendAPosted by Nobody/Anonymous on January 10, 2007 ok than I think that I will only use it for my functions. thanks for the fast response!
