3.1.1 Configuration Procedure

  1. Adjust the input supply to provide 3.3VDC with the current limited to 1A.
  2. Apply the input voltage to the EVM. See Section 2.1.2 for connections and test setup.
  3. Launch the Fusion GUI software. See the screen shots in Section 3.2 for more information.
  4. Configure the EVM operating parameters as desired.
