ENTER and EXIT CRITICAL with interruptsPosted by Jack Peacock on August 14, 2007 The preferred method for handling critical areas (where context changes might corrupt variables being updated) seems to be portENTER_CRITICAL() and portEXIT_CRITICAL(). Does this handle interrupts as well? Or do I need to mask out specific interrupt requests that might affect the critical region? Jack Peacock RE: ENTER and EXIT CRITICAL with interruptsPosted by Dave on August 15, 2007 Critical regions implemented using portENTER_CRITICAL/portEXIT_CRITICAL will have all interrupts disabled. Critical regions implemented using vTaskSuspendAll/xTaskResumeAll have interrupts enabled.
