IWR6843AOP: Interfacing to MMWAVE-SDK from host

Nadi Findikli

Part Number: IWR6843AOP

(just starting feasibility for using the IWR6843AOP in an embedded application)

Am I correct that all the functionality described in MMWAVE-SDK deep dive runs on the cores and DSP within the IWR6843AOP?

(Assuming yes) I see the following options for interfacing to the IWR6843AOP+MWAVE-SDK; is this correct?

CLI:

Can we access all advanced functions (like the output of the Object Detection DPC) via CLI?
Is there a better documentation of the CLI than Developer’s Guide mmWave Studio CLI Tool?

Custom Application:

We can add code to the application processor to perform the functions we need and interface over UART to our processor, right?

thank you

Hi Nadi,

Yes, you are on the right track.

The mmWave SDK comes with a demo. It is also included in our Industrial Toolbox, linked below, and described as the out of box demo. It uses 2x UART for external communication (one for configuration [CLI port], the other for data [DATA port]).

As for the CLI Tool you linked to, that is different. That is a command line tool best used for collecting RAW ADC data with the use of the DCA1000. Does not seem to be something you are looking for.

The external processor you mentioned will have to send a *.cfg file on the CLI port to the sensor, then receive data on the DATA ports.

Example *.cfg files are in the Industrial Toolbox linked above, in folder 'Chirp Database". Or create your own from the mmwave demo visualizer: https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/3.5.0/
