I need something similar to "pulseIn" of arduino in my nRF51822https://devzone.nordicsemi.com/f/nordic-q-a/4250/i-need-something-similar-to-pulsein-of-arduino-in-my-nrf51822I am using a US-100 ULTRASONIC SENSOR MODULE, and I need to measure the pulse width that this sensor produce. In arduino we can use a metode called "pulseIn", that gives you the measure of the pulse. My question is how can i make the same in my nRF51822en-USTelligent Community 13Thu, 30 Oct 2014 16:53:57 GMTRE: I need something similar to "pulseIn" of arduino in my nRF51822https://devzone.nordicsemi.com/thread/15176?ContentTypeID=1Thu, 30 Oct 2014 16:53:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a7072917-3f88-44cf-a322-8d035bf73299Vebjørn<p>This has been asked <a href="https://devzone.nordicsemi.com/question/17257/pulse-duration-on-a-pin/">before</a> :)</p> <p>As the answer says, you can generate an interrupt when the pin goes high that starts a timer, and an interrupt when the pin goes low that stops the timer and calculates the time it took.</p><div style="clear:both;"></div>
