This is my code for putting pin 5 HIGH: #define LATCH 5 #define ON 1 gpio_pin_configureen-USTelligent Community 13Wed, 21 Jul 2021 18:21:06 GMTRE: Use P0.05 AIN3 as outuputhttps://devzone.nordicsemi.com/thread/321192?ContentTypeID=1Wed, 21 Jul 2021 18:21:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c258b25d-4c56-459c-ae4f-a479fc63d06cSimon<p>Check out <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf52840_dk%2FUG%2Fdk%2Fvir_com_port.html&cp=4_0_4_6_1">nRF52840 DK --> Interface MCU --> Virtual COM port</a>.
