Original question:

IWR1443: Decoding the output data from IWR1443BOOST EVM

IWR1443: IWR1443 UART

Part Number: IWR1443
Other Parts Discussed in Thread: MMWAVE-SDK,

I am trying to use the mmWave SDK Demo software with the IWR1443BOOST evaluation board. Instead of using the demo GUI in PC through the USB port, can we use a MCU to control and receive data through the UART port to the demo board? If yes, any documentation for the installation/setup guide?

Thanks a lot,

Henry

    Hi Henry,

    You'll want to use the UART driver as part of the mmWave-SDK 2.1. There is documentation on this driver at the following location, C:\ti\mmwave_sdk_02_01_00_04\packages\ti\drivers\uart\docs\doxygen\html\index.html

    Let me know if you have more questions.

    Cheers,

    Akash

    Hi Akash,

    I am trying to find a simple way to communicate the IWR1443 evaluation board with a host MCU. Since the mmWave Demo Visualizer communicates with the evaluation board through the USB cable by the CFG_port UART and Data_port UART, can we discount the USB part and connect the MCU to the TX and RX pin of the UART port of the radar chip? A few other posts in the forum have mentioned about taking out some resistors connecting to the XDS part and putting zero ohm resistors on the UART TX and RX pins would allow direct connection from host MCU to the radar chip. Would that be the right way to do it? I think the XDS part is trying to channel the UART connection to the virtual com ports through the USB connection so a PC can send and receive data to/from IWR1443. We could just connect directly from the Host MCU UART to the UART port of the radar chip.

    Thanks a lot 

    Henry

    Hi Henry,

    You'll want to interface with the appropriate XDS_RS232 pins as shown in the schematic. This is on the IWR1443BOOST page under the Design Files section.

    For further hardware level queries I'd recommend opening up a new thread and we can ask a hardware expert to look into it.

    Cheers,
