3.2.1 Launching the Software

If installed in the default directory, then launch the DAC8050xxEVM software by searching for "DAC805xxEVM" in the Windows®Start menu.

Figure 4-3 shows the Device Setting configuration menu that is present when the GUI is launched. Select DAC80502-01 from the drop-down menu and click CONFIG.

After a device is selected, the Interface Settings menu pops up. This menu is shown in Figure 4-4. From this menu, select the interface protocol, as well as the I2C address. Select the CONFIG button to save the current settings and launch the main GUI. When using SPI, both devices can be used at the same time. When using I2C, make sure both devices have different I2C addresses.

Figure 4-5 shows the GUI after launch with the DAC80501 and DAC80502 register map loaded.

If the FTDI controller is not connected to the computer when the software is launched, then the GUI defaults to demo mode. Figure 4-6 illustrates the bottom-left corner of the GUI that shows the hardware connection status: DEMO MODE or CONNECTED. After the FTDI controller is properly connected to the computer, restart the DAC805xxEVM software to detect the device.
