How can I map an UART interface on other nrF51422 pins ?https://devzone.nordicsemi.com/f/nordic-q-a/16021/how-can-i-map-an-uart-interface-on-other-nrf51422-pinsI use a nRF51 dongle for some tests and I want to map the UART interface of UART_example on the pins 15,16,17 and 18 of the Dongle. I try to juste adapt this lines of code: #define UART0_CONFIG_PSEL_TXD 16 #define UART0_CONFIG_PSEL_RXD 18 #defineen-USTelligent Community 13Mon, 29 Aug 2016 08:48:20 GMTRE: How can I map an UART interface on other nrF51422 pins ?https://devzone.nordicsemi.com/thread/61096?ContentTypeID=1Mon, 29 Aug 2016 08:48:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9924e7b5-c3d7-41b8-9078-ca2faf58d263Ole Bauck<p>You can use thoes pins just fine.</p> <p><code>UART0_CONFIG_PSEL_xxx</code> is used in the <code>NRF_DRV_UART_DEFAULT_CONFIG</code> macro. The uart example does not use this macro, it uses</p> <pre><code>const app_uart_comm_params_t comm_params = { RX_PIN_NUMBER, TX_PIN_NUMBER, RTS_PIN_NUMBER, CTS_PIN_NUMBER, APP_UART_FLOW_CONTROL_ENABLED, false, UART_BAUDRATE_BAUDRATE_Baud115200 }; </code></pre> <p>You need to replace the <code>xx_PIN_NUMBER</code> defines with your pins.</p><div style="clear:both;"></div>RE: How can I map an UART interface on other nrF51422 pins ?https://devzone.nordicsemi.com/thread/61095?ContentTypeID=1Fri, 26 Aug 2016 14:04:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4402e425-532a-4a60-9bcc-1d1bea8bcd28Alex<p>Make sure those pins not used in your code for other peripherals.</p><div style="clear:both;"></div>
