the lack of light is a fresh air intake ;) cough-rice-cough the opposite in fact, pure function, even tho it makes the car look ugly (as bimmers should be) Thanks for putting the face on the name, the personal touch is important on such a project that HAS to be fairly close knit. I also appreciate ...

here, so you can put a face to a name:

replying on the comments: (i numbered them for you) 1. IMO the wheel/trigger/RPM/engine position stuff IS CORE FreeEMS code even if it changes from wheel to wheel. 2. the "hardware abstraction layer" needs to go 3. the line from the right hand "main loop" to the hardware needs to...

BTW, i've revised the diagram again and started the block description/summary. I don't see how scheduling the timer can be anywhere other than in the ISR. Never said it should be otherwise. Sorry if i wasn't clear - i meant 'calculate the time for timer scheduling' ...and calculate the time, to sche...

Can you detail any single ONE aspect of code, anything at all, that would NOT run in an ISR ? Where do you plan to determine what tooth the ign/inj events are triggered off of and calculate the time, to schedule a timer for, between the trigger tooth event and the actual event? Surely not in ISR! t...

NOTE: diagram and some other contents of the original post had been updated

Also, what IS a backend if it is not low level "get it done" code? Perhaps backend was not the best term for this. 'Plug-in' would have been better i think. It is a code that brings a particular flavour to 'getting it done' ;) In fact, it doesn't even have to be functional code - could be...

I am happy to see your feedback guys The diagram was an attempt to illustrate a very high level abstract architecture diagram. It does NOT represent data flow or sequence of events (this needs different type of diagrams), just the main components and connections/interfaces between them. Comments on ...

Here are some pics. Will update with more info later

Here is my input on the previous post: - I am not very familiar with the dizzy way of things, so i'd appreciate if you can elaborate on the dizzy one pin thing. - I would dispute this statement: "The injection must be timed such that each cylinder at the very least sees the same exact sequence ...
