https://devzone.nordicsemi.com/f/nordic-q-a/93626/nrf52840-gpio-interrupt-setting-issueHi there, There are some problems when setting nrf52840 GPIO interrupt. When I use gpio_pin_interrupt_configure_dt api to configure 11 gpio pins then download to my customer board. After all, I will get an Error number (Not enough core) on log whenen-USTelligent Community 13Tue, 08 Nov 2022 01:00:18 GMThttps://devzone.nordicsemi.com/thread/394562?ContentTypeID=1Tue, 08 Nov 2022 01:00:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ca0aaabf-6550-48b1-831a-e291afe48d50EthanZhao<p>Hi Einar,</p> <p>Thanks for your help~</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/394483?ContentTypeID=1Mon, 07 Nov 2022 15:08:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:809b927e-f9e6-4d1c-b962-9025a0786ad0Einarh<p>Hello</p> <p>The nRF52840 only has&nbsp;<a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fgpiote.html&amp;cp=4_0_0_5_9">8 GPIO event channels</a>, which is probably why you run into problems trying to define interrupts for many pins.</p> <p>You can get around this by using <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fgpiote.html&amp;cp=4_0_0_5_9_1&amp;anchor=concept_jyp_21x_lr">port events</a> rather than pin events.</p> <p>Best regards,</p> <p>Einar</p><div style="clear:both;"></div>
