How to measure Time/count Interval on External Interrupt?https://devzone.nordicsemi.com/f/nordic-q-a/47364/how-to-measure-time-count-interval-on-external-interruptHello , In this scenario, I have to measure the time interval between the START and STOP pulses generated by a peripheral device connected to nRF52 DK. The thing is START and STOP signals are passed through an OR gate to the nRF52(so, start and stopen-USTelligent Community 13Fri, 13 Dec 2019 14:44:36 GMTRE: How to measure Time/count Interval on External Interrupt?https://devzone.nordicsemi.com/thread/225415?ContentTypeID=1Fri, 13 Dec 2019 14:44:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cc9cbcc9-b071-4781-94ba-99320d94c182Knud<p>Hi.

We had a range to measure between 38nsec to 180nsec.&nbsp; Of course, 38nsec is not possible with the setup. Since single nop_ is 62.5nsec. If you don&#39;t have such a tighter resolution then it should work.</p><div style="clear:both;"></div>RE: How to measure Time/count Interval on External Interrupt?https://devzone.nordicsemi.com/thread/225275?ContentTypeID=1Fri, 13 Dec 2019 04:52:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:727841ee-fb96-4b47-9d70-a1b9c23aa722Knud<p>Hi.
