To get accurate spark timing, you will need many pulses per revolution of the crank. On my 4 cylinder suzuki, it has 22 pulses and a 2 non-pulse are to determine 'TDC on #1 cylinder. For a single cylinder engine I would think you need at least 6 pulses per revolution.
As the igntion timing is critical I need to pull the coil pin to low with an internal interrupt commandCan anyone help me with that?
Mhhh- a 360° stroke at 10.000RPM takes about 6mS. I am sure you agree that using interrupts is the best way to handle it not using IFTHEN loops. 1° of ignition is 17microseconds at 10.000RPM. The 328 is not as quick as that...I know I am naggy, but beside learning something about engines no one answered my question from my first post:As the igntion timing is critical I need to pull the coil pin to low with an internal interrupt command Can anyone help me with that?
