How to add UART1 to my nRF52DK program

[SidPrice]

I am using nRF Connect for VSCode to develop an experimental program on nRF52DK-nrf52832 board. I need to be able to use a second UART for my proof of concept and, being very unfamiliar with Zephyr, I cannot seem to figure out how to do this. I would much appreciate an example or advice as to where to start.

Hi Sid,

You could just make the necessary changes in DTS file.. In the version 2.0.0 and above of the SDK, the pins are assigned through the node Pin control.. You could take a look at the migration guide here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/ug_pinctrl.html#migration-of-the-devicetree-files and https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.1/zephyr/hardware/pinctrl/index.html 

You could also take a look at this ticket:  How to let hci uart work on nRF5340
