https://devzone.nordicsemi.com/f/nordic-q-a/82598/nrf52840-problems-with-pin-configuration-and-hx711-exampleHello, I tried to implement the HX711 example from Vidar mentioned here ( https://devzone.nordicsemi.com/f/nordic-q-a/34112/best-approach-to-interface-hx711-with-nordic-nrf52832 ) on my NRF52840 DK. Everything works fine if I use Pin 28 for PD_SCK anden-USTelligent Community 13Fri, 10 Dec 2021 13:34:15 GMThttps://devzone.nordicsemi.com/thread/342936?ContentTypeID=1Fri, 10 Dec 2021 13:34:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2107bc6d-db28-4d92-9e01-ac4f573c17e6Simonr<p>Hi Nicolas</p> <p>Are you sure these other pins aren&#39;t used for something else in your application, or does the HX711 require either of the pins to be an analog input perhaps?&nbsp; You can see what pins are analog pins here in the nRF52840 pin assignments:&nbsp;<a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fpin.html">https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fpin.html</a>&nbsp;</p> <p>You should also check the sample project to see if it uses any of the other pins as well. Here you can check out the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fpin.html">hardware drawings of the Dongle</a> to see what pins are available. Please note that soldering pin headers might be necessary. You should also check out our <a href="https://devzone.nordicsemi.com/guides/short-range-guides/b/getting-started/posts/nrf52840-dongle-programming-tutorial">Dongle Programming tutorial</a> to see what changes are necessary in the project to make it work on an nRF52840 Dongle.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
