Can taskENTER_CRITICAL_FROM_ISR() be used outside ISR?Posted by lantczak on December 27, 2016 Hi, Can I use taskENTERCRITICALFROM_ISR() in function that is NOT called from ISR? Will critical section work properly (preemption protection) in this case?

Can taskENTER_CRITICAL_FROM_ISR() be used outside ISR?Posted by lantczak on December 29, 2016 FreeRTOSv9.0.0FreeRTOSSourceportableGCCARM_CM4F Can taskENTER_CRITICAL_FROM_ISR() be used outside ISR?Posted by rtel on December 29, 2016 For that port the answer is 'yes' you can use the macros outside an ISR.
