The only thing I didn't get done that was suggested is make the program spark even if it doesn't have time to load the delay value. Sorry COM.

But you can see from the red line in the curve graph if you're trying to exceed what the program can fire. I'll work on this for the next version.

For using the two tables I suggest connecting a switch between ground and pin #2. You can use pin #1 for ground.


Nyemi, I don't really understand the calculations involved. I wrote a little test program to see how fast I could continuously spark. Using a spark plug with 0.035" gap (~0.8mm) I was able to fire at 63 uS. With 3 uS trigger pulse + 63 uS delay = sparks every 66 uS. That seems very low, but that is what I found.

Sparking at cylinder pressure will take more energy. If you know how to convert 66 uS at atmosphere pressure to the charge time at cylinder pressure, please share.
Everyone may have slightly different units also.
