Multiple if then optimization

[Mugelpower]

Hey Girls & Guys,

seems I poked into a bees nest.... I will try those codes in the evening (10 hrs from now).

Youre really helpful.

How about a code for extern interrupt that triggers a 1 ms high port after a delay found in a lookdown/case/if then row list? from 3 to 600 Hz of course......to get a constant phase shift between trigger and output.....

Its oughta be real fast!! 20MHz 16F628A preferred
"On interrupt" gets 180° phase shift (maximum limit) at 200 Hz.....

I dunno how to integrate a variable delay into DTs instant interrupts....

....

Could you explain that better ???

You're asking for a PBP written electronic ignition here ...

don't you think you abuse ... just a little bit !!!

Have an eye here ... : http://a110.free.fr/SPIP172a110/arti...?id_article=23

Ok, assembler ... but kit or scratch realizable, and the forum offers a Huge help ...

PS: I'm working on a full PBP version ... but Assembler interrupts can't be avoided !!!

Hi Acetronics,

yeah, in Principle thats that. BUT: thats french (ARGL-GARG!!) and I don´t understand 2% of it.
And: I have to modify the code it myself fromtime to time which could only be done if I´m knowing quite a lot about the code. Man, thats a BIG FISH to swallow for an oldschool mechanic. Learning programming, trying to avoid asm, learning that asm couldn´t be avoided...... ARGL-GARG !

Hi,

Generally speaking ...

Using PbP do not "protect" you from learning assembler ...it's a real "plus" to see the ASM result of your programming ...
and overall understand what's really happening, and how ...

Now about Ignition ... it's simple: you have an asm program to use with MPLAB , and a " Table generator " program ( in QBasic or, more recently EXCEL), just to load your timing values.
So, there are special knowledge of assembler needed ...

For French ... aha ... just think I spent a year in Berlin ( Yr 1990 ), and had to dig out my German school knowledge ... Euuuuhhhh, I'm also an old Mechanics ( and Thermics ) guy ...

Just Follow the scheme and components list ... you'll have done 90% of the work. ... on the Forum, we ALSO Compute tables for ... how to tell it ??? .... E.T.s ?

You also have this link ... in English :

http://www.transmic.net/index.htm

But ... not so good as ours ... yeah !!!

PS for Sayzer ...: I found a Turkish > French / French > Turkish free dictionnary on the Web; I do Hope you appreciate the effort ( LoL ...)

Hi Acetronics,

youve been to Germany? thats been a dark time I guess.....haha.

I already Knew the CDI transmic link but they have only the .hex file GRRRR....!

I found this too:

http://www.angelfire.com/ia/lfb/Pgbosch.html

but thats way more code and unneccessary extra sparks.

and by the way.....isn´t it more fun to get to the finish by ourselfs?

[Acetronics2]

We'll have to close this Ignition thread ... Because HS ...

a last one ...

no,no ... was a wonderful year ... indeed !!! Berliners are really smart people !
