IWR6843ISK: How to use the RX of UARTB (data port) of IWR6843ISK

Part Number: IWR6843ISK

Tool/software:

Hi,

Is it possible to utilize the Rx pin of UARTB on the IWR6843ISK to make the data port (UARTB) bidirectional?

I understand the necessary pinmux configurations, but I'm specifically looking for any hardware-related requirements. In the schematic, I don't see a clear pin-out for UARTB Rx—am I overlooking something?

Thanks

Regards

Gayatri

Gayatri,

Are you asking if this pin can be set as an input -or- an output?

Thanks,

Blake

No, How do i physically access this pin so that I can receive data via UARTB Rx?

Gayatri,

It would depend on where you are pin-muxing this signal from. If you are looking at using balls P4 and P7 there are some resistors you could use as connection points. The ball information can be found in the data sheet https://www.ti.com/lit/ds/symlink/iwr6843.pdf and the schematics can be found here https://www.ti.com/lit/zip/swrr164

I hope this helps!

Blake
