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)

beginInjectorPriming()

Perform the injector priming pulses. Set these to run at an arbitrary time in the future (100us). The prime pulse value is in ms*10, so need to multiple by 100 to get to uS

fuelSchedule1Interrupt()

void fuelSchedule1Interrupt

(

)

fuelSchedule*Interrupt (All 8 ISR functions below) get called (as timed interrupts) when either the start time or the duration time are reached. This calls the relevant callback function (startCallback or endCallback) depending on the status (PENDING => Needs to run, RUNNING => Needs to stop) of the schedule. The status of schedule is managed here based on startCallback /endCallback function called:

• startCallback - change scheduler into RUNNING state
• endCallback - change scheduler into OFF state (or PENDING if schedule.hasNextSchedule is set)
