IWR1642: Connect the iwr1642 to another PCB

Francesc Escudero

Part Number: IWR1642

Hello,

I bought the iwr1642boost and I have been testing it with the Labs. Now that I know how it works, I want to do a PCB design with only the sensor iwr1642 and connect it to another microcontroller. What do I have to do? I can not find any example codes of the sensor (iwr1642) that read the sensor measurements without the EVM. 

Thank you!

    Hello,

    Are you looking for info on HW development? Or just SW development without all the peripherals on the EVM? The SW from the labs will work fairly directly on a customer board, assuming the antenna pattern is different, the UART lines are mux'd out to where ever you are reading the data, and the HW design is complete and functional.

    The SW in the labs is loaded directly onto the IWR device (and flash for nonVolatile storage), so the same code should work.

    Is this what you are looking for?

    Regards,

    Hello,

    I have been looking the HW block diagram of the EVM  and I don't understand:

    1. If the code is loaded directly onto the IWR device what is the TM4C129 4NCP microcontroller doing?

    2. If the usb is directly connected to that microcontroller and the microcontroller to the IWR, then if we only have the IWR why should the same code work? 

    My goal is to work only with IWR's microcontroller and send the information directly out.

    Thank you for your help!

    Hello.

    1) That is the XDS110 emulation chip. It provides the USB com port emulation for the UART-USB transfer.

    2) The only thing the TM4C is doing is uart 2 USB conversion. So all the radar processing and data output from the IWR device is the same on other HW. If you want to connect another MCU directly to the UART pins on the IWR, you can do that in your customer HW. The MCU will just read in UART data instead of USB data.
