Other Parts Discussed in Thread: DCA1000EVM

Tool/software: Code Composer Studio

I read the c++ code of vital signs labs in CCS, and read the

I want to know:

1. Is the ADC data input to the radar HWA for 1D FFT the beat signal after dechirp? How to get the ADC data?

2. What is the signal received from the receiving antenna? The raw receive FMCW signal? or the beat signal?

Hi Huanpu,

You'll need to use the DCA1000EVM for raw data capture. The Vital Signs demo does not have the raw adc data and only works with the post-processed data.

Hi，Akash：

what is the post-processed data? Could you describe it in detail?

The demo give the final vital sign result and it is not enough for us.

Our goal is collect the output data of 1D FFT in HWA, and perform some algorithm on these data. We only have the IWR1433 hardware.

Can I modify the C++ code in CCS project to achieve this goal？

Could you give me some ideas? Thanks very much.

The Post-Processed Data is described in the Vital Signs Developer's guide.

Let me know if you have more questions on it.

Cheers,
Akash
