IWR1642BOOST: Capturing and Storing Processed Data?

Jon Leverfield

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642, IWR1443BOOST, AWR1642BOOST,

I am considering the IWR1642 BOOST EVM for capturing continuous range data vs. time on a drone. 

The goal would be to continuously capture and store DSP-processed data (e.g. 1-D FFT output for range) from the L3 memory to external flash memory e.g. SD card. Is there any recommendation on an external MCU (would the suggested MSP432 be usable here?), or would this be possible with the onboard MCU? This would be for rudimentary field testing, so I am hoping to keep the setup simple/small. 

It seems like recording such processed data from L3 memory to PC is possible on the BOOST board using the mmWave SDK demos (only available for x86 Windows/Linux PCs); is this correct? If so, a small x86 single-board computer running Windows/Linux and the mmWave SDK would be an option for me.

I understand the TSW1400+DEVPACK setup is required for recording raw ADC samples, but was hoping to avoid this for field testing processed data because of the size and complexity of the boards.

Thanks for your help.

    Hello Jon,

    I am looking into the answer. I will get back to you on this shortly.

    Hello Jon,


    The Out of Box demo example sends such post processed data over the UART port of the mmWave device and which get sent over USB out of the EVM board. That would be a good option to get data from the device. If you do have the option of recording over machine like PC which will allow you to collect the data over USB interface then you can try it with our IWR1443BOOST or AWR1642BOOST EVMs.


    Data is continuously streamed over the usb interface of EVM when Out of Box demo is invoked and it can be saved for further processing provided the capture machine has enough data space. Typically this should not be an issue with PC based captures.

    TSW1400 + mmWave EVM allow Raw ADC data which is sent over LVDS interface of the device to the TSW1400 board. This is helpful when you wish to capture at speed data which becomes available at the end of every FMCW chirp. If you desire post processed data and are ok with slower update rates between two consecutive Frames then USB capture would be easier and better option.


    Thank you,

    Hi Vaibhav,

    Thanks for the reply. I will pursue PC data recording for now on the IWR1642BOOST.
