Users can follow the instructions in this chapter to build a 5 Mega Pixel camera using their DE4 / DE2_115 / DE2-70 / DE2 / DE1 in minutes. 3. 1 Demonstration Setup The image raw data is sent from D5M to the DE4 / DE2_115 /DE2-70 / DE2 / DE1 board. The FPGA on the DE4 / DE2_115 /DE2-70 / DE2 / DE1 board is handling image processing part and converts the data to RGB format to display on the DVI / VGA monitor. For DE2-70, the image captured at SDRAM can be taken at anytime (snapshot) and uploaded to a PC as a BMP/JPG file. 3. 2 Camera Demonstration Setup On DE4 Board Locate the project directory from the CD-ROM included and follow the steps below: Directory: Demonstration / DE4_230/530_D5M_DVI FPGA Bitstream Used: DE4_230/530_ D5M_DVI.sof 1. Ensure the connection is made correctly as shown in Figure 3-1. Make sure the D5M is connected to JP4 (GPIO 1) and DVI daughter card is connected to J20 (HSMC PORT A) of the DE4 board with two THCB-HMF2 interface cards which are bundled in the DE4 kit. 2. Insert the DDR2 memory card into J9 (DDR2 SO-DIMM-1). 3. Connect the DVI TX output of the DVI daughter card to a DVI monitor. 4. Copy the directory DE4_230/530_D5M_VGA from D5M System CD-ROM to the host computer. 5. Download the bitstream (DE4_230/530_D5M_DVI.sof) to the DE4 board. 6.
