Follow these steps to run the DGP software to change the display content and settings:

1. Turn off the supply power.

2. Set the operation mode switches to the Host Mute operating mode as defined in Section 1.2.1.

3. Turn on the supply power. Figure 2-3 shows the LED status of the EVM when in the Host Mute operation mode.

   Figure 2-3 Host Mute Operating Mode LED Status

4. At start-up in Host Mute operation mode, the default content projected is a static image of vertical color bars.

5. Confirm the FTDI cable is connected to the PC. While running DLP Control Program, click on the Connection list. If the FTDI cable is not already connected, click the Connect button. Note, the Connection settings must be a clock rate of 5 MHz and timeout of 500 ms.

6. Python scripts can be run from the Scripting window. The script shown below can be used to select one of the pre-programmed test patterns of the DLP2021-Q1 DGP composer project. Press the green button to run the script, and the projected content toggles between a static image and video.
