Al it does it capture a timmer/counter when a pulse comes in. Then fets a flag a user program can read that says "data available". The user level programs reads the device ad gets the captured counter value, the flag is reset. Very simple and very low overhead.
How does the pulse trigger the capture ? If some hardware line is polled, how frequent is that polling ? The counter units may well be nanoseconds, but the inherent uncertainty of the polling instant must be taken into account.
If instead there is no polling, but it is a hardware triggering, then could you please give more details ? Thanks. 73 Alberto I2PHD _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
