NRF52840 Input Capture pinhttps://devzone.nordicsemi.com/f/nordic-q-a/55916/nrf52840-input-capture-pinHi, We are in developing stage of one of our project. Integrating Flow sensor with Pulse type output.Can you please suggest a pin to connect with Pulse count feature(Input capture pin) in NRF52840. And want to know whether what can be duty cycleen-USTelligent Community 13Fri, 27 Dec 2019 09:05:07 GMTRE: NRF52840 Input Capture pinhttps://devzone.nordicsemi.com/thread/226893?ContentTypeID=1Fri, 27 Dec 2019 09:05:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6a718808-a182-4400-b515-b73dbacc4b2dJared<p>Hi,</p> <p>A pulse of 5Hz to 120 Hz should be well within what the nRF52840 can support.&nbsp;</p><div style="clear:both;"></div>RE: NRF52840 Input Capture pinhttps://devzone.nordicsemi.com/thread/226853?ContentTypeID=1Thu, 26 Dec 2019 06:26:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed03688b-ca33-4967-ba1b-b582592d8033jagadeesh surneni<p>Hi,Jared</p> <p>Ok then i will connect to GPIOTE pin to capture.</p> <p>is there any dependency on duty cycle ratio,and what can be the max frequency it can capture??</p> <p>Pulse output sensor frequency range</p> <p>The output frequency range varies somewhat from model to model, but generally ranges from about 5 Hz at the bottom of the flow range for any model to 120 Hz at maximum flow</p> <p></p> <p>Will this frequency range is supported by the NRF52840?</p> <p></p> <p></p> <p></p> <p>Regards,</p> <p>JAGADEESH</p><div style="clear:both;"></div>RE: NRF52840 Input Capture pinhttps://devzone.nordicsemi.com/thread/226785?ContentTypeID=1Tue, 24 Dec 2019 04:25:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07300f51-527e-435f-9636-df489d0c473bVenkatesan<p>Hi,Jared</p> <p>Ok then i will connect to GPIOTE pin to capture.</p> <p>is there any dependency on duty cycle ratio,and what can be the max frequency it can capture??</p> <p>Pulse output sensor frequency range</p> <p>The output frequency range varies somewhat from model to model, but generally ranges from about 5 Hz at the bottom of the flow range for any model to 120 Hz at maximum flow</p> <p></p> <p>Will this frequency range is supported by the NRF52840?</p> <p></p> <p>Regards,</p> <p>Venkatesan</p><div style="clear:both;"></div>RE: NRF52840 Input Capture pinhttps://devzone.nordicsemi.com/thread/226727?ContentTypeID=1Mon, 23 Dec 2019 12:43:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0ccd34a0-aaea-4cc4-969c-1628a79cbe5cJared<p>Hi</p> <p>See <a href="https://devzone.nordicsemi.com/f/nordic-q-a/34547/ppi-configuration-to-count-pulses/133136#133136">this post</a>.</p> <p>regards</p> <p>Jared</p><div style="clear:both;"></div>
