Devices and Systems for Running the Script

​ Device: IWR6843AOP+MMWAVEICBOOST+DCA1000EVM

​ System: Windows10, Ubuntu18.04

Flashing the provided bin image file from the SDK

​ Path

D:\ti\mmwave_sdk_03_06_02_00-LTS\packages\ti\demo\xwr64xx\mmw\xwr64xx_mmw_demo.bin

​ Set SOP to flashing mode, then click the RST button on top of MMWAVEICBOOST.

​ SOP0 1 ​ SOP1 0 ​ SOP2 1

Set SOP to development mode

​ After flashing the bin image file, set to development mode, then click the RST button on top of MMWAVEICBOOST.

​ SOP0 0

​ SOP1 0

​ SOP2 1

Windows Platform

Install Driver

​ Unzip ftdi_driver_2_12.zip, manually select the local driver.

Install Dependencies

pip install -r requirements.txt

Configure IP Address

Check if ports are correctly recognized

Linux Platform

Install FTDI driver for USB communication

sudo apt-get install libftdi1 libftdi-dev

Check if ports are correctly recognized

ll /dev/serial/by-id

​ Output result:

Where ttyACM0 and ttyACM1 are the command port and data port respectively.

Port paths are as follows:

ls /dev

Result:

/dev/ttyACM0
/dev/ttyACM1

Where ttyACM0 corresponds to COM4 on Windows system

Configure IP Address

​ Same as Windows platform

Notes

1. Log file information is saved in the logs directory of the current directory, the log file name is mmwave.log, the log file will be created automatically, no need to create manually.

2. Before running the code, you need to modify the port to the corresponding local port, as shown in the figure Application/User UART corresponding port number,

   

   def main():
       setup_logging()  # Set up logging
       data_dir = './data'  # Directory for data files
       serial_port_CLI = '/dev/ttyACM0' if platform.system() == 'Linux' else 'COM4'  # Serial port based on OS
       start_time = None  # Initialize start time
       end_time = None  # Initialize end time

   For Windows platform, modify the COM4 port on line 200 of the main.py code file

   For Linux platform, modify the /dev/ttyACM0 port on line 213 of the main.py code file

3. The default baud rate is 115200

4. Enter q to exit the program; enter s to start the collection task, enter s again to end the collection task; enter r to reset the board and millimeter-wave radar,

Run the program

python main.py

Run the program on Linux version

bash run.sh

​ or

source mmware/bin/activate

Configuration Files

cf.json DCA1000EVM Configuration File

The current collection method is automatic collection, the area that needs attention is the captureConfig configuration

    "captureConfig": {
      "fileBasePath": "data",
      "filePrefix": "adc_data",
      "maxRecFileSize_MB": 1024,
      "sequenceNumberEnable": 1,
      "captureStopMode": "infinite",
      "bytesToCapture": 4000,
      "durationToCapture_ms": 180000,
      "framesToCapture": 12000
    },

Among them, captureStopMode is configured as infinite collection mode, that is, the DAC1000 board works continuously.

As shown in the figure, in the Frame column, No of Frames is 12000, Periodicity is 5ms, the total duration is 60000ms, the collection time is determined by the millimeter-wave radar, and the collection channel is automatically closed after collection is completed.

Other parameters need to refer to the TI_DCA1000EVM_CLI_Software_UserGuide.pdf document

docs/TI_DCA1000EVM_CLI_Software_UserGuide.pdf

profile.cfg IWR6843AOP Millimeter-wave Radar Configuration File

%* <startIdx> <endIdx>
% <loopNum>[should be 4x] <frameNum> <framePerio:ms>
% <trigSel 1:Software,2:Hardware>[1] <frameTrigDelay:ms>
frameCfg 0 2 16 12000 5 1 0

Among them, the frameCfg parameter corresponds to the Frame column in the above figure. The third parameter <loopNum> cannot be filled with 1, it can only be filled with 16, this value is automatically generated according to mmWare Demo Visualizer.

frameNum corresponds to No of Frames

framePerio corresponds to Periodicity

<frameNum> and <framePerio:ms> jointly determine the data collection time length:

​ 12000：5 is 60 seconds ​ 2000：5 is 10 seconds ​ 6000：5 is 30 seconds

Other parameters need to refer to the mmwave_sdk_user_guide.pdf document

docs/mmwave_sdk_user_guide.pdf

Files generated by the script

data/adc_data_Raw_0.bin: Raw data file

data/adc_data_Raw_LogFile.csv: Collection data log file. Windows platform can normally write collection history information, Linux platform needs Ubuntu18.04 platform.

Aug_07_2024_13_46_18_447_Aug_07_2024_13_47_20_827_2.bin: Renamed raw data file.

​ Aug_07_2024_13_46_18_447 is the timestamp of the start of data collection,

​ Aug_07_2024_13_47_20_827 is the timestamp of the end of data collection, accurate to milliseconds,

​ _2 is the file sequence number.

logs/mmwave.log:

​ Python script log
