C++ (Cpp) portSAVE_CONTEXT_OS_INT Exemples

Exemple #1

Fichier : port.c Projet : savpek/TLCR-Firmware

/* The preemptive scheduler is defined as "naked" as the full context is saved
on entry as part of the context switch. */

	#else
		/* Clear the interrupt flag. */

	/* Because FreeRTOS is not supposed to run with nested interrupts, put all OS
	calls in a critical section . */
	portENTER_CRITICAL();
