https://devzone.nordicsemi.com/f/nordic-q-a/33271/some-issues-of-gpio-interruptHi, I have some questions about GPIO interrupt. Now, I want to know the state of the pin, So I use the gpio_pin_read(PIN) to get the state. But when the pin is suspended, the value returned from gpio_pin_read(PIN) is uncentain. Actually, it must been-USTelligent Community 13Mon, 23 Apr 2018 09:34:42 GMThttps://devzone.nordicsemi.com/thread/129306?ContentTypeID=1Mon, 23 Apr 2018 09:34:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b9782d0-573d-421b-9efa-66c2df31ca39FormerMember<p>When there a pin has no pull, it is normal that the value is in certain. To control the value of the pin, pull-up or pull-down has to be used.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/129265?ContentTypeID=1Mon, 23 Apr 2018 06:53:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fec3edf9-6e47-4033-b225-7a1d1d22a2dfliluo18<p>1. When the pin is suspended, use gpio_cfg_input(PIN, NRF_GPIO_PIN_NOPULL), and then gpio_pin_read(PIN). The value read is uncentain.</p> <p>2.Question 2 has been solved, it was a hardware problem.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/127964?ContentTypeID=1Thu, 12 Apr 2018 07:35:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:82004088-db45-413c-92ed-564509f1546dFormerMember<p>How did you configure the gipo?</p> <p>How did you configure GPIOTE? And how do you handle the GPIOTE events (do you remember to clear the events)?</p><div style="clear:both;"></div>
