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.

Actually I need to measure the time period of the signal (which can start from one rising/falling edge to the next rising/falling edge). in other words i need to measure rising+falling edge and then add both of them. the consecutive means this operation should be carried out untill the last input signal at GPIO present. Actually Im measuring the signal from my other application by using nrf52840 and sending through BLE.

If you’re trying to detect message signals, I suggest you to look into UART or other protocols. GPIOTE and PPI and TIMER operations are for really simple purposes.

This what i want to measure. if im able to get t1,t2,t3....... then I can measure the T and Frequency of the signal also. The main goal is to measure the frequency of the input signal at GPIO.
