Configure Radar Using a Configuration (.cfg) File for Reading Raw ADC (IQ) Data

To configure the TI mmWave radar board, you must send a sequence of commands to the board using the serial port. The sequence includes commands specifying the chirp profile, sampling rate, required outputs, and so on. For more information on the commands, see the Configuration (.cfg) File Format section in mmWave SDK user guide. Use the ConfigFile property of the dca1000 object to send the sequence of commands to the board.

You can use a sample configuration file provided with the support package instead of generating a configuration file. The sample files are stored in the configfiles folder in TI Radar Support package install directory. To navigate to this directory, execute the following commands in MATALB command window.

installDir = matlabshared.supportpkg.getSupportPackageRoot
tiradarCfgFileDir = fullfile(installDir,'toolbox','target', 'supportpackages', 'timmwaveradar', 'configfiles');
cd(tiradarCfgFileDir)

Once you identify the config file you need to use to configure the TI radar, specify this file name with full file path and extension as the value of the property ConfigFile of the dca1000 object

For example, if tiradar is the name of the dca1000 object that you created and you want to configure the radar using the file C:\Configs\ xwr68xx_2Tx_BestRange_UpdateRate_10.cfg, then specify the config file as shown below:

tiradar.ConfigFile = "C:\Configs\ xwr68xx_2Tx_BestRange_UpdateRate_10.cfg";

The dca1000 object sets a few properties of the object based on the parameters in the configuration file.
