* Add optimized 32-bit shifting
* Tooth based time to angle coversion is only used by a few decoders.
So move the functions into decoders.cpp
* Better separation of deocders and crank maths.
* Apply optimised shifts
* Doxygen
* Reset control pin: don't over-writie the board default with zero.
The added unit tests interfered with each other & hung -
solution is to reinitialize the global context at the start of
each test.
* Additional pin init tests
* initialiseSchedulers: factor out shared code.
* Proxy setFuelSchedule\d through generic
setFuelSchedule() function
* Directly call setFuelSchedule
* Simplify unit tests
* Proxy setIgnitionSchedule\d through generic
setIgnitionSchedule() function
* Directly call setIgnitionSchedule
* Simplify unit tests
* Optimize by partially inlining
the set[Fuel|Ignition]Schedule funcs
* Use the embedded schedule compare
& counter members instead of using
hardcoded individual channel macros.
* Unit test adjustCrankAngle
* Add udiv_32_16
* Apply udiv_32_16() where possible
* Convert udiv_32_16 to assembler
It's worth 20 loop/s
* Remove unused functions
* Remove degreesPeruSx2048 - unused
* Remove angleToTime - replace with direct calls
1. Drop angleToTime()
It's slow, only partially implemented and adds zero value
(and has MISRA violations)
2. Consistent function naming
3. Doxygen
* triggerPri_Nissan360 shouldn't set timePerDegree.
It will be overwritten every loop by doCrankSpeedCalcs()
* Use angleToTimeMicroSecPerDegree() instead of timePerDegree
No loss in performance
Increased injection open/close time accuracy (so unit test values must change)
Can remove timePerDegree global.
* Hide (encapsulate) crank math globals.
* Base all angle to time conversions on decoder computed variables.
This is within 2us of the revolution based method
and is much faster - which is essentially zero percent change.
* Performance: move calculation of degreesPeruSx32768
into decoders.
Remove doCrankSpeedCalcs() - it's doing nothing
at the moment.
* Apply libdivide to triggerSetEndTeeth functions.
Since triggerToothAngle is set once at initialization
time, we can generate the libdivide struct
once and reuse it many times.
* Remove lastToothCalcAdvance - unused
* Replace 16-bit division with shift
* Replace 32-bit divison with 16-bit division
* Avoid 32-bit division; use div100()
* inline percentage()
* Optimize div100()
* MISRA fixes
* Replace magic numbers with #defs
* Replace libdivide structs with inline constants
No perf or memory changes
* Use fixed types for PWM max count variables
* Accurate rounded integer division
* Formalise rounding behavior (DIV_ROUND_CORRECT)
* Apply DIV_ROUND_CORRECT to DIV_ROUND_CLOSEST(),
UDIV_ROUND_CLOSEST(), div100(), div360(),
percentage() & halfPercentage()
* Add, fix & improve unit tests
* Add udiv_32_16_closest()
* Perf: Limit percentage calculations to 16-bits
* MISRA fixes
* Add compare_executiontime() to encapsulate common perf testing code
* Signed to unsigned division
* Convert ignitionLimits() to an inline function.
Slight speed up, probably due to removing
multiple evaluations of macro arguments.
* Split unit tests up.
* udiv_32_16 - check for valid parameters
* Added taper for DFCO for ignition and fuel
Used 1 byte of RAM and 4 on page 9
* Moved data to be compatible with DFCO map thres
* Added taper for DFCO for ignition and fuel
Used 1 byte of RAM and 4 on page 9
* Moved data to be compatible with DFCO map thres
* Fixed potential overflow and DFCO tests
* Moved math into functions and added tests

* Renix 44-2-2 & 66-2-2-2 initial version
coded, not tested yet, saving to secure code
* First working version on ardustim
* updates to trigger setup
* latest changes
* 66 tooth working but occasional short dwell
* staging before major rewrite
updating the primary trigger to look for 12th system tooth to increment toothCurrentCount after this checking
* updated working but with bad dwell/timing
code works but the timing and dwell are not accurate once rpm goes over 400rpm
* Renix code 1st release
updated code to do both 44 and 66 tooth within a single set of functions
* remove support for sequential for 44 tooth
Sequential (via cam) was added for 44 tooth to enable future expansion. This is interfering with the normal code on the first testers car.
* updated cam position
* remove Dev logging
* remove logging
* updates to trigger decoding
fixes to 66 tooth pattern and removal of secondary flag for 44 tooth decoder
* fixes to decoder - rpm double
* updates to support display cam tooth position
added code to display which teeth the cam tooth arrives on as VVT1 & 2 and as Aux0 and Aux1.
* Revert "updates to support display cam tooth position"
This reverts commit d2ace89ea7.
* fixes from update to latest speeduino firmware
* Add 4cyl semi-seq injector pairing option
* Add timestamp field to SD logs
* Fix soft and hard rev limiter (#813)
* Increase dwell limiter in RX-8 type ignition (#820)
Currently the dwell limiter calculation considers rotary ignition to have more than 1 pulse per revolution. This only holds true for FC/FD type ignition which is wasted spark correctly resulting in 2 pulses per revolution. RX-8 type ignition however is fully sequential so there is only 1 pulse per revolution. As a result the dwell limiter is being calculated too low.
This change fixes the issue by correctly assuming 1 pulse per revolution in RX-8 type ignition
