Functions
void	nullCallback (void)
	A scheduler callback that does nothing.
void	setCallbacks (Schedule &schedule, Schedule::callback pStartCallback, Schedule::callback pEndCallback) noexcept
	Set the schedule callbacks. I.e the functions called when the action needs to start & stop.
static uint16_t	clipDuration (uint16_t duration)
static void	setScheduleNext (Schedule &schedule, uint32_t delay, uint16_t duration) noexcept
static void	setScheduleRunning (Schedule &schedule, uint32_t delay, uint16_t duration) noexcept
void	setSchedule (Schedule &schedule, uint32_t delay, uint16_t duration, bool allowQueuedSchedule)
	Set the schedule action to run for a certain duration in the future.
void	moveToNextState (FuelSchedule &schedule) noexcept
	Shared fuel schedule timer ISR implementation. Should be called by the actual timer ISRs (as timed interrupts) when either the start time or the duration time are reached. See Schedule finite state machine.
template<typename T >
static void	increment_volatile (volatile T &value)
	Increment a volatile variable correctly.
static void	onEndIgnitionEvent (const IgnitionSchedule *pSchedule)
	Called when an ignition event ends. I.e. a spark fires.
	BEGIN_LTO_ALWAYS_INLINE (void) static ignitionPendingToRunning(Schedule *pSchedule)
	Called when the supplied schedule transitions from a PENDING state to RUNNING.
void	moveToNextState (IgnitionSchedule &schedule) noexcept
	Shared ignition schedule timer ISR implementation. Should be called by the actual ignition timer ISRs (as timed interrupts) when either the start time or the duration time are reached. See Schedule finite state machine.

Detailed Description

Injector and Ignition (on/off) scheduling (functions). There is usually 8 functions for cylinders 1-8 with same naming pattern.

Scheduling structures

Structures FuelSchedule and Schedule describe (from scheduler.h) describe the scheduling info for Fuel and Ignition respectively. They contain duration, current activity status, start timing, end timing, callbacks to carry out action, etc.

Scheduling Functions

For Injection:

• setFuelSchedule*(tout,dur) - Setup schedule for (next) injection on the channel
• inj*StartFunction() - Execute start of injection (Interrupt handler)
• inj*EndFunction() - Execute end of injection (interrupt handler)

For Ignition (has more complex schedule setup):

• setIgnitionSchedule*(cb_st,tout,dur,cb_end) - Setup schedule for (next) ignition on the channel
• ign*StartFunction() - Execute start of ignition (Interrupt handler)
• ign*EndFunction() - Execute end of ignition (Interrupt handler)

setCallbacks()

void setCallbacks ( Schedule &  schedule, Schedule::callback  pStartCallback, Schedule::callback  pEndCallback  )

noexcept

Set the schedule callbacks. I.e the functions called when the action needs to start & stop.

Parameters

schedule	Schedule to modify
pStartCallback	The new start callback - called when the schedule switches to RUNNING status
pEndCallback	The new end callback - called when the schedule switches from RUNNING to OFF status

setSchedule()

void setSchedule	(	Schedule &	schedule,
		uint32_t	delay,
		uint16_t	duration,
		bool	allowQueuedSchedule
	)

Set the schedule action to run for a certain duration in the future.

Parameters

schedule	Schedule to modify
delay	Delay until the action starts (µS)
duration	Action duration (µS)
allowQueuedSchedule	true to allow a schedule to be queued up if one is currently running; false otherwise
