nRF52 Pulse Duration Counter for GPIO - The time between 2 consecutive rising edges

[Khalil Ahmad]

Im trying to measure the time between 2 consecutive rising endges (Rising and Falling Edge together) on GPIO continuously but I did not find any leads. will appreciate the support.

[Khalil Ahmad]

after implementing the ppi example I start getting these values. But these values are in ms. How can I increase to nano seconds only the output so that i can capture upto 900 nano seconds

You can’t measure 900ns exactly in 16MHz timer. One tick is 62.5ns. You can only measure 875ns or 937.5ns.

[Khalil Ahmad]

Yes, then I will try to start from 875ns.

14ticks with 16MHz timer should do 875ns okay. Still not sure what kind of program you want to make. Would you summarize it?
