OpenWSN IEEE802154E timings

Note
These parameters are BOARD and CPU specific. Values can't be taken directly from OpenWSN since they do not necessarily use the same BSP configuration (timers, clock speed, etc.) For precise synchronization these values should be measured and tuned for every BOARD. To understand the relationship between these values and OpenWSN state machine as well as how they can be measured refer to:
#define SLOTDURATION   20 /* in milliseconds */
 

Adaptive sync accuracy

     Used for synchronization in heterogeneous networks (different BOARDs)
     Not supported yet, dummy value needs to be provided.
#define SYNC_ACCURACY   (1) /* ticks */
 

Macro Definition Documentation

◆ DISABLE_INTERRUPTS

#define DISABLE_INTERRUPTS ( )
Value:
irq_state = irq_disable();
irq_disable
MAYBE_INLINE unsigned irq_disable(void)
This function sets the IRQ disable bit in the status register.

Definition at line 49 of file board_info.h.

◆ ENABLE_INTERRUPTS

#define ENABLE_INTERRUPTS ( )
Value:
irq_restore(irq_state);
irq_restore
MAYBE_INLINE void irq_restore(unsigned state)
This function restores the IRQ disable bit in the status register to the value contained within passe...
