Hello you all!

its several years since I postet something here.

My current problem:

I need to measure the average speed of a car. I got an input signal from the driveshaft (one per revolution) wich I use for a distance couter with a 16F88 . The program uses "on interrupt" Now I need to divide the distance by real time after pushing a button. I got two favorite PICs because I´m an total inept programmer : 16F88 and 18F1320. Wrote my last program some years ago.
The clock and the incomming driveshaft pulses both use interrupts and I think thats too much for one of these PICs. No I´m not migrating to DSPic or 24F.

Any suggestions out there?
