DCA1000EVM: Chirp Configurations and Saving Data

Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR1243BOOST,

Hello,

I have two questions.

One, how do you turn chirp signaling off? I want to transmit a signal from the AWR1243Boost chip without there being a frequency change or slope; I just want a stable single.

Two, how does the DCA1000EVM save data? I know that the data saves in the adc_data.bin file, but every time I trigger a new frame and do Post Proc, it keep showing the bin file from when I first ran the program. How do I get the chip to overwrite old data so it can show me the new data?

Thanks,

Jazmean

    Hi Jazmean,

    You need to use the continuous mode of mmWave Sensor, where it generates a signal with fixed frequency constantly.

    Please refer mmWave Studio User guide (section 11) for this feature.

    With DCA1000, it should save to a new file or overwrite the existing file (if same path is given in Studio text path). You can try to move the lastly captured file to a different location then recapture to check this issue.
