Figure 4-4 shows that if the onboard FTDI controller is connected correctly, then the status bar at the bottom of the screen displays CONNECTED. If the controller is not properly connected or not connected at all, then the status displays DEMO. If the graphical user interface (GUI) is not displaying the CONNECTED status while the EVM is connected, then unplug and reconnect the EVM and relaunch the GUI software.

Figure 4-5 shows the DAC8811 Register page of the DAC8811EVM GUI. This page allows direct access to the data register of the DAC8811. The GUI handles page address management, allowing seamless access to the register.

The Register Map section in the center of the page lists the register. Directly above the Register Map section are four buttons that allow access to the data register.
