To operate the GUI, follow these steps:

1. Connect to and launch the GUI as described in Section 4.1.3.1.
2. Close the README.md file page that pops up after the EVM connects to the GUI. The text near the bottom-left hand corner of the GUI reads Hardware Connected.
   Figure 4-6 Hardware Connected
   1. If Hardware Connected does not show in the bottom-left hand corner of the GUI, then check different hardware COM ports under Options >> Serial Port.
      Figure 4-7 Change Serial Port
   2. If the hardware still does not connect, make sure you are using the correct GUI and EVM combination.
3. Click the Registers icon shown in Figure 4-8 (also available on the left-side menu) to view the register map, change device settings, and enable automatic register read. For questions about a register or register bit field, select the icon. For more questions about registers, check the data sheet.

4. Click the Plots icon shown in Figure 4-9 (also available on the left-side menu) to view and save graphical data from the results registers. This screen shows the x-axis, y-axis, z-axis, angle, magnitude and temperature plots that are derived from the corresponding TMAG5x73 result registers. These plots have been converted to real world units of mT and degrees. Click the SAVE PLOT button on the corresponding plot to save any specific plot.
