https://devzone.nordicsemi.com/f/nordic-q-a/23261/can-i-use-an-analog-pin-as-a-digital-pinhai in nrf51822 the pins p0.01 t0 p0.06 are marked as analog pins in the nrf51822 DK. i know that in arduino we can use an analog pin as an analog input as well as a digital in/out. so like that can i use any pin from p0.01 t0 p0.06 as a digitalen-USTelligent Community 13Wed, 05 Jul 2017 11:37:51 GMThttps://devzone.nordicsemi.com/thread/91468?ContentTypeID=1Wed, 05 Jul 2017 11:37:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:10f3739d-3c9a-4121-a569-ff478106ee5eiqbalpalemad<p>hai. i am using a custom board of nrf51822. now the problem is solved . the issue was with the mbed API. thank you for your help.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91467?ContentTypeID=1Wed, 05 Jul 2017 11:29:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4f92e6ba-65b1-4d92-8548-7f3df89b2bb7Sigurd<p>Are you using a nRF51-DK? Is it only P0.06 you have problem with? The other pins are working as expected ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91465?ContentTypeID=1Wed, 05 Jul 2017 09:22:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:145e13d5-5aaa-4b22-a142-3cfd8b1bfc12iqbalpalemad<p>actually i am working with mbed compiler to program. and i have tried p6 same as a digital pin. but the behaviour is not as expected.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91466?ContentTypeID=1Wed, 05 Jul 2017 09:18:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:abc1f68f-4c75-458c-b846-cc742d531775Sigurd<p>Yes, 100% the same as using any digital pin. You can configure the pin as output with the function <code>nrf_gpio_cfg_output(pin number)</code>. See infocenter page <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.3.0/group__nrf__gpio.html?cp=4_0_2_6_6_7_9#ga5c6f584e6e01dd0c65bd1b9eee958cbb">here</a>.</p> <p>After that use <code>nrf_gpio_pin_set(pin number)</code> to set the pin high, and <code>nrf_gpio_pin_clear(pin number)</code> to set the pin low.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91469?ContentTypeID=1Wed, 05 Jul 2017 08:50:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2bab9b2-3955-44b1-8971-d9386c971e0fiqbalpalemad<p>how to set an analog pin as digital out. can you give me the syntax. is it same as setting a digital pin...?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/91464?ContentTypeID=1Wed, 05 Jul 2017 07:50:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cc734e17-9d79-4b96-bfaa-366e0aac85c1Sigurd<p>Hi,</p> <p>Yes, all the analog pins can also be used as Digital I/O pins.</p> <p>From the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf51/dita/nrf51/pdflinks/51822_ps.html?cp=3_4_0">nRF51822 Product Specification</a> page 13:</p> <p><img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/6866.gpio.png" alt="image description" /></p><div style="clear:both;"></div>
