https://devzone.nordicsemi.com/f/nordic-q-a/16015/set-gpio-pinHello! I want to set the Pin2 (GPIO) on VCC. I have try it by nrf_gpio_pin_set(2) but it doesn’t work. Is there a better way to set Pin2? Thanks!en-USTelligent Community 13Fri, 26 Aug 2016 12:28:07 GMThttps://devzone.nordicsemi.com/thread/61084?ContentTypeID=1Fri, 26 Aug 2016 12:28:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:708b721f-b841-4d2d-8d38-e92999b703f6Alex<p><a href="http://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.3.pdf">Product specification</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/61083?ContentTypeID=1Fri, 26 Aug 2016 12:26:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:57cdc681-50f4-410e-9620-44e36583fd11Nitram<p>where could I see which GPIO goes to which Pin?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/61085?ContentTypeID=1Fri, 26 Aug 2016 11:16:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29da98bd-e803-44e7-b112-a727a3059f1bEinar Thorsrud<p>You would have to enable the pin before you set it, for example like this:</p> <pre><code>uint32_t pin = 2; nrf_gpio_cfg_output(pin); nrf_gpio_pin_set(pin); </code></pre><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/61082?ContentTypeID=1Fri, 26 Aug 2016 11:08:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:505e2233-edcb-4f6a-af26-e01d343bea89Alex<p>Have you configured it as output? And by the way (2) means GPIO2 signal, not physical pin number on chip.</p><div style="clear:both;"></div>
