Hi,

Hardware

1.MMWAVEICBOOST

2. IWR6834ISK

3. DCA1000

How do i get the ADC row data from the mmWave. what is the api to read the ADC samples

advice

Thanks

Hello,

Please refer to the DCA1000 User Guide on the Radar Toolbox in the TI Developer Zone for a step-by-step tutorial on how to get raw data from start to finish. There are quite a few steps, and it is important to follow them in order.

Hi,

I meant the code itself
what is the api to read ADC row data i dont want to use object detect?

Hello,

There is not exactly a traditional API with Radar ADC data capture. It is dumped into a .bin file after recording is finished. Recording is done with mmWaveStudio or CLI Tool which can both be found in the Radar Toolbox. Then this .bin can be processed however you want, for example in MATLAB with the bin to MATLAB script example that can be found in the mmWaveStudio installation. Format of .bin file can be found at the bottom of the guide linked in the prior post.

Hi,

I know... i don't mean work with DCA1000.

I want to build project on the dss that get the ADC row data and build my signal procesing code on that.

There is a way to get ADC Row data instead of object location

Hello,

You cannot collect ADC data without a DCA1000 for signal processing development.

Hi,

I don't want to collect I want to run my algorithm on the ADC line data.

If I can't access the ADC data, what data can I access?
The calculation in the examples is while running calculates objects in space. I want to use my algorithm

Hello,

You cannot send ADC data over UART/USB which is what the examples use due to the transfer speed required to send unprocessed unfiltered dumped ADC data. It is for this reason you need the DCA1000. You then collect raw data using the DCA1000 and then use your algorithms in programs such as MATLAB to see how the processing chain works.
