4.1.5 Image/Video

This page allows the user to select the image/video content that is to be programmed into the SPI flash memory.
For the content to be a selectable option, the image/video file must be available in the following directory DLP
Composer project: “(

dgp_project_root)\Inputs\Videos

”. Check the

Build

check box for the contented to included

or excluded from the firmware build.

Figure 4-5. DLP Composer - Image/Video

This EVM allows users to store approximately twenty seconds of full-color content in the 2-Gb SPI flash device.
However, content duration can be increased by optimizing content and setting the correct illumination (RGB or
single color) to match the type of content being displayed. The video content must be in .MP4 format to be
compatible with DLP Composer.

4.1.6 Flash Blocks

The flash memory for the DGP system is divided into five major blocks. Creation of the flash binary is handled
entirely by DLP Composer. The FPGA Configuration for the Xilinx XA7S15-1CPGA196Q Spartan®-7 FPGA is
already compiled and included with the example project provided by Texas Instruments.
