3.2.1 Starting the Software

To launch the software, navigate to the Texas Instruments folder in the Start menu, and select the DAC63004WCSP-EVM icon.

Figure 3-4 shows that if the onboard controller is connected correctly, the status bar at the bottom of the screen displays CONNECTED. If the controller is not properly connected or not connected at all, the status displays DEMO. If the GUI is not displaying the CONNECTED status while the EVM is connected, unplug and reconnect the EVM, and then relaunch the GUI software. If the display continues to display DEMO, uncheck the Demo Mode checkbox (see Figure 3-6, upper-right corner).

Figure 3-5 shows the Interface Settings window. When the GUI starts, the Interface Settings window pops up. This window contains drop-down menus that select protocol (SPI or I2C) and, if I2C protocol is selected, the I2C device address.The menu does not pop up if the GUI starts in Demo mode. In this case, uncheck the Demo Mode checkbox. If the interface must be updated again, toggle the Demo Mode checkbox for the menu to reappear.

The SDO pin on the DACx3004W is connected to the GPIO2 output from the onboard controller. Before configuring the SDO pin as an output to enable readback, remove J6 to disable the GPIO outputs from the onboard controller or remove R13 on the DAC63004WCSP-EVM to disconnect the GPIO2 pin from the SDO pin.
