To access the dts value in C/C++ code, you could use the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/guides/dts/api-usage.html">Devicetree API</a>. You could also take a look at <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/reference/devicetree/api.html?highlight=dt_gpio_pin#c.DT_GPIO_PIN_BY_IDX">this</a> for the required macros.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
