5.1.3.2 GUI Operation

To operate the GUI, follow these steps:

  1. Connect to and launch the GUI as described in Section 5.1.3.1.
  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.

    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.

    2. If the hardware still does not connect, make sure you are using the correct GUI and EVM combination.
  3. Click the Registers icon to open the Registers page (also available on the left-side menu). Note that the registers listed are not registers on the TMAG5328 but are internal variables stored in the microcontroller that are not directly used for EVM evaluation. These variables cannot be modified from the Registers page and can be ignored.

  4. At the top of the Registers page, change Auto Read to As fast as possible. GUID-20211108-SS0I-05ZG-R6PG-JP7J1ZR3BSJZ-low.png

The TMAG5328 also has a Results page for viewing the state of the TMAG5328 OUT pin and a DAC configuration page for configuring the DAC. Both of these pages are described in the sections below.
