matlab联合mmWave Studio采集毫米波雷达原始数据相关官方文档

  1. From mmWaveStudio’s Lua Shell, call the RSTD.NetStart() command This command starts a listening server on port 2777 by default.
    (you can also add this command to “C:\ti\mmwave_studio_01_00_00_01\ mmWaveStudio\Scripts\Startup.lua” so that it is called automatically)

  2. There are two Matlab scripts shown below. Copy them and create scripts with names RSTD_Interface_Example.m and Init_RSTD_Connection.m. You can modify the path to the RtttNetClientAPI.dll in RSTD_Interface_Example.m, and then call the RSTD_Interface_Example from Matlab. This script demonstrates how to connect to mmWaveStudio from Matlab and allow Lua commands to be sent to mmWaveStudio. The script internally calls Init_RSTD_Connection.m to establish the connection to port 2777, and then displays a green message in the mmWaveStudio Output window.

    See lines 41-47 in Init_RSTD_Connection.m for an example of sending a single Lua Command. Basically, you construct the Lua command as a string in Matlab and pass it to the RtttNetClientAPI.RtttNetClient.SendCommand API. Also see commented lines 12-15 in RSTD_Interface_Example.m for an example on how to get mmWaveStudio to run an external Lua Script.
