Steve,what is your cycle time ? Less than 0.5us ?
did you use more than one interrupt to capture the burst?


Hi Edgar,
I got it with two interrupts, INT0 and Timer0. Conversion starts with my enabling and zeroing timer0. If timer 0 is running there is no measurement in progress, and the existing position data is clean.

Start timer0:with any clock pulse, reset timer0. When the timer overflows, you are in the inter-burst space, so the next edge is the start of the first bit of the first data packet At the end of the conversion, disable timer0. I needed a bit counter and a byte counter to sequence the data into the right places. How do you handle the serial- parallel conversion ?
