MMWAVE-STUDIO: IWR1443+DCA1000, question on the DCA data

MMWAVE-STUDIO: DCA1400 - Multiple Trigger Commands

Other Parts Discussed in Thread: IWR1443

Hello,

I have a hardware configuration of IWR1443 + DCA1400.

After a single Trigger command, DCA1400 is writing raw data as "adc_data_Raw_0.bin" as expected. The data size also matches with the Chirp+Frame configuration. However, if I need to Trigger a new chirp block, I have to arm DCA again, which clears the above mentioned data.

Is there any possibility to trigger multiple chirp blocks and append the new raw data to the same .bin file.

Thanks.

    Muhammet,

    mmWave does not support appending to the same file.

    What you could do is extend your configuration, by increasing the frame count, you can then calculate the size of each frame and separate accordingly.
    Something else that might be helpful, you could move the file and rename it every capture, mmWave's Lua supports the command os.exceute; example: os.exceute("copy <SRC_FILE> <DEST_FILE>").
    Essentially any command that you run from the windows command prompt you can do with os.excecute, so you could move it, rename it and later append it somehow.

    Hope this helps

    Thank you Alex.

    The second option you suggested can meet the requirements at my application.

    Thanks again.
