High priority/low priority program parts

So, now you're saying it does - sort of - work? No more 300ms delays?

Regarding the LCD: You can try tweaking the default 1500us setting but it's highly dependant on the specific LCD module you're using.
I suspect most of what's on the LCD is static text. If that's true you might gain a fair bit of time (and a much better appearance on the LCD) by just updating the part of the LCD that's actually changing.

Hello Henrik,
I set the baud rate to 38400, that helped a bit.
Then tried set the LCD_COMMANDUS to 1500 that gained hardly anything but made the LCD a bit unreliable.
The count time is down to 75, 50 is loo little, i get no signal when cranking,100 slows the routine cycle down to 8Hz.
Now I got the frequency of a complete routine up to 11.5 Hz.
I guess that should do.
Now I´m back into hardware, soldering and juggling tools, after that testing with real electric motors.
Noise suppression is a real challenge in car electric.

I appreciate your help and the help of all of you folks.
