https://test-devzone.nordicsemi.com/f/nordic-q-a/88564/button-pulldown-questionhello. I want to use the button as a pull-down. I am using nrf52832, and the button and circuit part are composed of pull-down and the code is written as follows. However, even if the button is pressed, it always behaves as 0. I want to know whyen-USTelligent Community 13 Non-ProductionTue, 07 Jun 2022 05:05:51 GMThttps://test-devzone.nordicsemi.com/thread/371012?ContentTypeID=1Tue, 07 Jun 2022 05:05:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:17e6d3b2-4a94-4066-9a33-7500ebbd44b9user97123<pre class="tw-data-text tw-text-large tw-ta" id="tw-target-text" dir="ltr"><span class="Y2IQFc" lang="en">I have solved this problem! It happened because I misunderstood the circuit. <br /><br />The chip I used is nrf52832 and is written from sdk15.2. Not DK. Thanks for the reply! And for other developers who may have the same problem, in NRF52dk, GPIOs 13~17 are internally pulled-up, so if you use it as a button, you must do a pull-up set. <br /><br />Also, if you use GPIO 13~17 as a pull-down in a non-dk version, you should not use the bsp handler. <br /><br />Actually I think the best way is to use 20 or more GPIOs with nothing defined... <br /><br /> I am writing the answer through a translator, there may be mistranslations.</span></pre> <p>Thank you!!</p><div style="clear:both;"></div>https://test-devzone.nordicsemi.com/thread/370816?ContentTypeID=1Fri, 03 Jun 2022 08:18:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:57971533-43ea-47ed-8047-d36c24f17fefuser111520<p>Hello!</p> <p>Are you using the nRF52832 DK or a custom board?</p> <p>What SDK are you using?</p> <p>Best regards,</p> <p>Einar</p><div style="clear:both;"></div>
