To operate the GUI, follow these steps:

1. Connect the EVM to TI-SCB and mount the Roate & Push Module.
   Figure 3-10 TMAG6180-6181EVM with Magnet Knob Attachment
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).
   Figure 3-11 Hardware Connected Indicator
   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).
      Figure 3-12 Change Serial Port
   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.
   Figure 3-13 Plots Page Icon
5. Select the Sensor to test using the drop-down menu shown in the figure below:
   Figure 3-14 Device Select Drop-Down
6. Click Collect Data to initiate data capture.
   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.
      Figure 3-16 TMAG6180 Quadrature Output Indicators
   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.

8. Click Stop Collect to stop data capture.

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