GUI Operation

To operate the GUI, follow these steps:

  1. Connect the EVM to TI-SCB and mount the Roate & Push Module.

  2. Connect to and launch the GUI as described in Section 3.2.1.3.1.
  3. With the EVM connected to the GUI, close the README.md file page. The text near the bottom-left hand corner of the GUI reads Hardware Connected (see Figure 3-11).

    1. If Hardware Connected does not show in the bottom-left hand corner of the GUI, check different hardware COM ports under Options → Serial Port (see Figure 3-12).

    2. If the hardware still does not connect, make sure you are using the correct GUI/EVM combination.
  4. Click on the Plots icon to setup the EVM for measurements.

  5. Select the Sensor to test using the drop-down menu shown in the figure below:
    GUID-20230315-SS0I-R6F2-FGHL-SRJ9F1VT4M67-low.svg Figure 3-14 Device Select Drop-Down
  6. Click Collect Data to initiate data capture.
    GUID-20230315-SS0I-L9WN-JPSR-DPPQJLDHVB7R-low.svg Figure 3-15 Data Collection Settings
    1. Delay between samples setS the sample rate.
    2. #Samples sets the plot record length.
    3. #Samples Only stops collecting after the specified samples are captured, and disabling this checkbox causeS data to stream continuously.
  7. Observe the status indicators relative to the device being tested:
    1. TMAG6180-Q1: Q0 and Q1 indicates the quadrant of rotation for the magnetic source. The quadrant of rotation is also indicated by LEDs mounted on the EVM.

    2. TMAG6181-Q1: Turns count increments and decrements by 0.25 as each quadrant change occurs. The PWM output is captured and converted for position tracking.

      1. Additionally, the PWM output can be probed directly using the Turns test point.

  9. Click Save Plot or Save all Plots to store captured data locally.
