Effective Debounce 7 Individual Inputs on nRF52840https://devzone.nordicsemi.com/f/nordic-q-a/86579/effective-debounce-7-individual-inputs-on-nrf52840I am trying to determine the best way to debounce 7 digital inputs with 2 bounce times ranging between 50 ms to 2 seconds. I thought of using the GPIOTE but that seems to only have 7 channels and I&#39;m already using 3 of them for other interrupt activitiesen-USTelligent Community 13Wed, 06 Apr 2022 07:51:43 GMTRE: Effective Debounce 7 Individual Inputs on nRF52840https://devzone.nordicsemi.com/thread/361979?ContentTypeID=1Wed, 06 Apr 2022 07:51:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:66510cd2-a185-4b3f-90ce-9a13f9004a28Kenneth<p>The app_button library use PORT event for lowest power, this means that it can support more than 7 GPIO&#39;s.</p> <p>Kenneth</p><div style="clear:both;"></div>RE: Effective Debounce 7 Individual Inputs on nRF52840https://devzone.nordicsemi.com/thread/361952?ContentTypeID=1Wed, 06 Apr 2022 05:41:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a453a787-d75c-437b-9876-754a4b9b3de2WestCoastDaz<p>Kenneth,</p> <p>Thank you very much for pointing me to that. Is it possible to have more than 7 GPIOs setup to interrupt the processor? &nbsp;I have an additional 3 GPIOs that I need to monitor.</p><div style="clear:both;"></div>RE: Effective Debounce 7 Individual Inputs on nRF52840https://devzone.nordicsemi.com/thread/361516?ContentTypeID=1Mon, 04 Apr 2022 12:39:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7d5f8b2f-7f69-4712-9a77-70037db03321Kenneth<p>Hi,&nbsp;</p> <p>You may check out the app_button library in the nRF5 SDK:<br /><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_button.html">https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_button.html</a></p> <p>An example that show usage can be the:<br />\examples\ble_peripheral\ble_app_blinky\</p> <p>See&nbsp;buttons_init() and&nbsp;button_event_handler().</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
