IWR6843ISK: Acquiring Raw ADC Data from IWR6843ISK without Using mmWave Studio

Tool/software:

Hello,

I am currently using the IWR6843ISK radar sensor with a custom DCA1000 setup (based on Zynq FPGA). I would like to acquire raw ADC data without using mmWave Studio 2.1.1.0.

Through analysis, I confirmed that mmWave Studio configures the IWR6843ISK parameters over the following path:

mmWave Studio → USB → FTDI → SPI → IWR6843ISK

In our custom system, we plan to bypass mmWave Studio and directly configure the radar device ourselves.

I have a few questions to help us achieve this:

• 1. Project Recommendation for CLI-Based Raw Data Acquisition

  • Could you recommend a suitable firmware project (e.g., out_of_box_6843_isk_mss or any other) that allows us to configure the IWR6843ISK and collect raw ADC data without relying on mmWave Studio?

• 2. SPI Configuration Protocol Details

  • Could you provide documentation or details on the SPI command protocol that mmWave Studio uses to configure the IWR6843ISK?

  • Specifically, we need to know how to set radar parameters such as chirp profile, frame configuration, etc., over SPI or UART.

• 3. CFG File-Based CLI Configuration and Raw Data Access

  • Is it possible to configure the IWR6843ISK using a CLI command interface (via UART) and then acquire raw ADC data through LVDS using our FPGA board?

  • If yes, could you provide an example CFG file and list the required commands (e.g., sensorStart, adcCfg, etc.) to enable raw data output?

Our goal is to fully automate sensor control and data capture, without using mmWave Studio or the default DCA1000EVM.

Thank you in advance for your support.

Best regards,
Jaehoon Kim
