Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843, DCA1000EVM

I am new to RADAR sensor, and I need examples for running AWR1843BOOST on MATLAB directly.

Thanks

Hello Mostafa,

Can you please provide more details on what you are trying to do?

Do you plan to capture raw data and develop your own algorithm in Matlab?

Regards,

Ishita

Hello Ishita,

Currently I am trying to read the data from AWR1843 directly to MATLAB using UART.

Hello Mostafa,

By reading data, do you mean Raw ADC data and then you want to do processing on MATLAB or do you want processed raw ADC data (using onboard DSP and HWA) and send the object data (x,y,z,velocity ...) out using UART?

I believe its the former case, and for that purpose you would need DCA1000.

Still, I think it would be better if you could understand both these cases in detail and then know your requirements.

Here are some previously answered questions on this by our experts for your reference :

Hi Ishita,
Thanks for reply.
I mean I want to send object data to MATLAB through UART from awr1843 directly, I have read the links and thanks for that. I have read in this link: https://e2e.ti.com/support/sensors/f/sensors-forum/976365/awr1843boost-some-detailed-information-about-the-board/3607308#3607308
you sent that, "there is no actual "capture" of the data" when using onboard DSP and HWA. Why I can't capture data in this case, Is that because it's already processed onboard or what?
second question I need to know more details about the object data?

Hi,

AWR1843 has inbuild capability to crunch the raw ADC data using DSP & HWA, and provide the final object data over UART. In this case you can connect Matlab to this UART (which is emulated as COM port from USB cable connected to AWR1843BOOST) and read/process this data.

I would recommend you to look at TI-Rex which has many of application on AWR1843 and for other mmwave device variants, these would help you to explore the options for your experiments.

Here is MRR -beamformaing application based on AWR1843, where it sends object data over UART and Matlab based VIsualizer listens that data to plot on the screen.

On top of that you can modified or write a new application to send the raw ADC data over LVDS (and capture using DCA1000EVM on PC) and same time do the processing on device using DSP/HWA.

Jitendra
