3.2.1 Software Setup

Open the PPC3 application in the directory chosen for the GUI installation in Section 3.1. Figure 3-2 shows the resulting app center window. Click on the PCMx120-Q1 app tile.

Before changing any parameters, check the lower left corner of the PPC3 window, as shown in Figure 3-5, to verify that the EVM is connected. If no EVM is detected, the text will read PCMx120-Q1 offline. If the EVM is detected, a Connect button appears. Clicking this button connects the hardware.
