3.1.3.1 Initial Setup

To set up the GUI for the first time:

  1. Make sure that the previously mentioned driver was installed successfully to verify that everything works properly and that the GUI can update the EVM firmware, if necessary.
  2. Check to make sure the EVM/SCB Controller unit is plugged into the PC, then go to the previously-provided GUI link.
    1. Verify that the EVM is connected to the SCB before plugging the SCB into a USB port.
  3. Click the GUI Composer application (see Figure 4-2) to launch the GUI from the web browser.
