IWR6843AOP: Using one UART for both Config and Data

Robert Greger

Part Number: IWR6843AOP
Other Parts Discussed in Thread: , IWR6843

I have a microcontroller with only one available UART for connection to a board with an IWR6843AOP. Can I use just one UART on the IWR6843AOP for both configuration and data? Is there a reference design or demo software for that implementation?

Hi Robert,

This should be fine. We don't have a demo that supports it right now, but the changes should be fairly straightforward.

Best,

Nate

Hi Nate,

So I can just alter the demo to output the data to the cliCOM port on the IWR6843AOP at 115200 bps?

Hi Robert,

There should be no problem with this from the IWR6843's perspective. However, if you're using an EVM, I would recommend using the Enhanced COM Port on the CP210x for both the CLI and data because the TX on the standard COM Port is not connected to the IWR6843 chip on the IWR6843AOPEVM.

Best,

Nate
