Syntax for placing UART on GPIO1 in the DTS

[basvkesteren]

Hi,

This might be a simple one, but i cannot figure it out.. How do I place the rx/tx/rts/cts lines from UART0 on a GPIO1 pin?

In the piece of DTS below, 'tx-pin' is on GPIO0 pin 18. What is the syntax to move this to a GPIO1 pin?

&uart0 {
	compatible = "nordic,nrf-uarte";
	current-speed = <115200>;
	status = "okay";
	tx-pin = <18>;
	rx-pin = <19>;
	rts-pin = <20>;
	cts-pin = <21>;
};

Hi,

To assign pins on port 1, add '32' to the pin number. For example, if you want to use P1.5, you would add 5 + 32 = 37. You can also use the devicetree Visual Editor UI for this.

Best regards,

Vidar

Thanks!

Did not know about the visual editor, will check it out! When we started with this project the nrf vscode plugin didn't exist yet. Never took the time to really look into it since...
