Variable Documentation

◆ blockScheduling

volatile uint8_t blockScheduling

Block scheduling.

While set to a value different from zero all scheduling will be blocked.

Definition at line 27 of file OCB.c.

◆ currentTask

volatile TaskType currentTask = INVALID_TASK

Task currently being executed.

Definition at line 23 of file OCB.c.

◆ forceScheduling

bool forceScheduling

Force the next rescheduling.

If set to true the next call of OS_Schedule() will perform a rescheduling even if current task is marked as non-preemptive.

This should only be set immediately before OS_Schedule() is called.

Definition at line 28 of file OCB.c.

◆ isCat2ISR

volatile uint8_t isCat2ISR

Priority of current Cat 2 ISR (zero if not in Cat 2 ISR)

Definition at line 21 of file OCB.c.

◆ isISR

volatile bool isISR = false

Is currently ISR context?

Definition at line 20 of file OCB.c.

◆ isrResourceQueue

struct resource_s* volatile isrResourceQueue = NULL

Resource queue for resources taken by Cat2 ISRs.

Definition at line 32 of file OCB.c.

◆ needScheduling

volatile uint8_t needScheduling

Scheduling needed during timer interrupt.

If set to 0 the system timer will not trigger rescheduling.

Definition at line 26 of file OCB.c.

◆ needSysTickEval

volatile uint8_t needSysTickEval

SysTick must be evaluated during timer interrupt.

This indicates whether or not the change in SysTick value must be evaluated during the timer ISR. The value should be zero if no subsystem (like alarms) require evaluation of the sysTick counter.

Definition at line 30 of file OCB.c.

◆ sysTick

volatile uint32_t sysTick

Current system tick.

Definition at line 25 of file OCB.c.
