Well, you don't get an IC interrupt for the "missing tooth" do you, so no code runs then, you are just forced to schedule around it. Or do you have a cunning way to fake it somehow? Even if you are faking it, it just boils down to estimation and prediction at the end of the day. No interrupt is no interrupt afterall.
stops... thinks... realises...
You meant on the interrupt BEFORE the missing tooth didn't you. Such that there is twice as much time. Thats a good point for wheels that have missing teeth, but in the case where they don't, its not a lot of use. You could certainly schedule some "once per rev" stuff into that slow in the missing tooth decoder if there is a need for such code to run.
