3.2 Getting Started GUI

Source code for this reference design is provided so the designer can debug firmware directly, as explained in Section 3.3. However, software debugging needs more time. To speed up development time, a UART based GUI software is provided to help quickly tune parameters on any customized application. This section introduces how to debug and tune the motor control parameters with the GUI software.

For now, only the C2000 daughter-board firmware supports the GUI.

Use caution when connecting the host PC to this reference board via UART, because the AC rectifier generates the DC-output voltage, which has a HOT Ground floating from the protective earth ground. Isolation transformers must be used when connecting grounded equipment to the Kit.
