Function Documentation

applyChannelOverDwellProtection()

TESTABLE_INLINE_STATIC void applyChannelOverDwellProtection	(	IgnitionSchedule &	schedule,
		uint32_t	targetOverdwellTime
	)

Here is the call graph for this function:

Here is the caller graph for this function:

applyOverDwellProtection()

void applyOverDwellProtection	(	const config4 &	page4,
		const statuses &	current
	)

Check that no ignition channel has been charging the coil for too long.

The over dwell protection system runs independently of the standard ignition schedules and monitors the time that each ignition output has been active. If the active time exceeds the tune defined amount, the output will be ended to prevent damage to coils.

Note

Must be called once per millisecond by an external timer.
