hi poslathian, you're right I don't care about the actual physical time based off a unit like microseconds or milliseconds. All I care about is some tick/clock counter that has a set increment in time that can be counting in and out of an interrupt. I can always do some conversion at some point to put it into microseconds so I can refer it to actual time, this would be to calculate rotational velocity etc.
Its the next major item I need to tackle in my code, so I'll try and spend some time today on it today or tonight.
