Hi I was wondering if anybody has done this before or has
any ideas on how to do this.

I have to count the number of pulses happening in a second
coming from two different devices.  One of them will have a
maximum of approx. 200 pulses a second (It is a heart-rate
monitor) and the other will be approx. 15000 pulses a
second (This is from a fly-wheel sensor).

Now this is my problem, as the two events are at such
different speeds does anybody have any idea on how to count
both of them so that I get a fairly accurate result for
each.

The idea I had was to count the number of events for the
fly-wheel in the main-line section of code and use an
interrupt to count the heart-rate, this way I will not
hopefully lose any of the pulse for the heart-rate.

Any help on this will be gratefully received.

Thanks

Jon
