Here are the list of queries on mmWave Sensor Visualizer.

 

Q1. Where I can find Demo Visualizer User guide document?

Q2. Not able to connect from mmWave Demo Visualizer

Answer:

  • Make sure that TICLoudAgent Bridge (browser extension) is installed on the browser (preferably Chrome) to use the Visualizer.
  • Refer troubleshooting page to find some level of solution regarding the TICloudAgent
    • http://processors.wiki.ti.com/index.php/TI_Cloud_Agent#Troubleshooting
    • Make sure USB cable with EVM is already connected with the system before starting the Visualizer or refresh the Visualizer page.
    • Goto Visualizer-> Options-> Serial Port: click refresh button on the popup window.
    • Try connecting COM port from other serial application (e.g. TeraTerm) to make sure that COM port is accessible to connect.
    • Restart the PC if COM port is blocked by some application in the background.

 

Q3. Not able to get the Plot with mmWave Demo Visualizer

Answer:

  • Compatible application (mmw demo) should be running on mmwave sensor and it should be of same SDK version and device type which Visualizer supports.
  • If sending config commands doesn’t appear to ‘console message’ window then
    • first check if right COM port is connected to CFG_PORT and DATA_PORT with right baud rate.
    • Disconnect COM ports from Visualizer and now try to connect CFG_Port with a serial Terminal tool (as TeraTerm) and hit enter, you should get the prompt “mmwDemo:/>”. Try giving “version” command over same prompt, is it reverting right version?
    • Before sending any cfg command, Visualizer sends ‘version’ command in background to get to know the matching version. If it doesn’t get any response from the application over data_port or non-support version then it won’t proceed further to send cfg commands. So check over serial terminal for ‘version’ command.
  • Next assuming Visualizer is able to send all the cfg commands but still not getting any plot
    • Again go back to TeraTerm connection but this time connect two separate COM ports (CMD_Port and Data_Port) at same baud rate.
    • Send one by one all the CFG commands from *.cfg (in mmw demo profile folder) over TeraTerm (CMD_port) and check if all the commands return DONE message.
    • At last, when you send sensorStart command from the same TeraTerm console, on another console (DATA_port) you should see some data coming up (may not be readable: binary object result data). So this way it proves that device is fine and pumping out object data over Data_port, there is some issue with Visualizer connection or execution.
    • At this step try to use other browsers or PC to open Visualizer. Or reinstall the TICloudAgent extension.

 

Q4. Adding a new plot to visualizer or sending in b/w result data out.
