Speeduino main loop.

Main loop chores (roughly in the order that they are performed):

• Check if serial comms or tooth logging are in progress (send or receive, prioritise communication)
• Record loop timing vars
• Check tooth time, update statuses (currentStatus) variables
• Read sensors
• get VE for fuel calcs and spark advance for ignition
• Check crank/cam/tooth/timing sync (skip remaining ops if out-of-sync)
• execute doCrankSpeedCalcs()

single byte variable currentStatus.LOOP_TIMER plays a big part here as:

• it contains expire-bits for interval based frequency driven events (e.g. 15Hz, 4Hz, 1Hz)
• Can be tested for certain frequency interval being expired by (eg) BIT_CHECK(currentStatus.LOOP_TIMER, BIT_TIMER_15HZ)

Sometimes loop() is inlined by LTO & sometimes not When not inlined, there is a huge difference in stack usage: 60+ bytes That eats into available RAM. Adding attribute((always_inline)) forces the LTO process to inline.

Since the function is declared in an Arduino header, we can't change it to inline, so we need to suppress the resulting warning.

Here is the call graph for this function:

getAdvance1()

static int8_t getAdvance1 ( void  )

inlinestatic

Lookup the ignition advance from 3D ignition table. The values used to look this up will be RPM and whatever load source the user has configured.

Returns

byte The current target advance value in degrees

Here is the call graph for this function:

Here is the caller graph for this function:

getVE1()

static uint8_t getVE1 ( void  )

inlinestatic

Lookup the current VE value from the primary 3D fuel map. The Y axis value used for this lookup varies based on the fuel algorithm selected (speed density, alpha-n etc).

Returns

byte The current VE value
