Is there an existing node for a UART Driver with no flow control? Peripheral only has tx/rx.

[MontanaEE]

When I look at eh graphic .overlay, I see that the UART0 is there, but no node is assigned.  Is there a Node for a two wire UART Driver with no flow control?  Peripheral only has tx/rx.  I have the UARTE Enabled and setup in my main and project file, but not following how to create a node in the intermediate course.

Thanks

Hello,

Which Nordic chip/ Development kit are you working with? Which  SDK version are you using here?

When I look at eh graphic .overlay, I see that the UART0 is there, but no node is assigned. 

I assume you are referring to the Device Tree view in the VS Code extension; please correct me if I’m wrong. If you check the DTS file in the boards folder, you will find that UART0 is defined in the default DTS file. Even though UART0 is defined there, you can customize its configuration with an overlay. This allows you to enable only the TX and RX pins without flow control and choose specific pins for TX and RX.

Enabled and setup in my main and project file, but not following how to create a node in the intermediate course.

Could you point out which lesson of the intermediate course you are following here?

Kind Regards,

Abhijith

Good afternoon,

Yes, I am referring to the device tree view.  I am using the Pinnacle 100 DVK, which utilizes an nrf52840. I do have the pins defined without flow control in the DTS, but I thought I had to have a node configured for UART0 like the HL7800 shows up under UART1 below.  I have been trying to work through Lesson 7 in the intermediate course.
