Working with the Metrology GUI

To view the metrology parameter values from the GUI, perform the following steps:

  1. Select UART connection for communication to the PC GUI. Connect J12 to PC USB and a COM port is created on the PC. The testing was done using UART with 9600, 8N1 setting.
  2. Open the GUI folder and open calibration-config.xml in a text editor.
  3. Change the port name field within the meter tag to the COM port connected to the system. As Figure 4-2 shows, this field is changed to COM7.

  4. Run the calibrator.exe file, which is located in the GUI folder. If the COM port in the calibration-config.xml was changed in the previous step to the COM port connected to the reference design, the GUI opens (see Figure 4-3). If the GUI connects to the design properly, the top-left button is green. If there are problems with connections or if the code is not configured correctly, the button is red. Click the green button to view the results.

The results window opens after clicking on the green button (see Figure 4-4).
