3.1.2.1 Software Setup

Open the PPC3 application in the directory chosen for the GUI installation in Section 3.1.1. Figure 4-2 shows the resulting app center window. Click on the PCMx140Q1 app tile.

The PCMx140Q1 GUI is designed to work with up to four devices at any time. As shown in Figure 4-3, choose the 1 device radial button and click New.

Before changing any parameters, check the lower left corner of the PPC3 window, as shown in Figure 4-5, to verify that the EVM is connected. If there is not an EVM detected, then the text reads PCMx140Q1 offline. If the EVM is detected, then a Connect button appears. Clicking this button connects the hardware.

When the hardware is connected, the Connect button changes to read Disconnect, and the device is ready to be configured.
