The kit contains hardware design (in Verilog) and software to load the picture taken into a PC and save it as a BMP file. The Getting Started User Guide enables users to exercise the digital camera functions. This chapter provides users key information about the kit. Kit Contents 1-1 Figure 1.1 shows the photo of the TRDB_DC2 package. The package includes: 1. The TRDB_DC2 (DC2) board with one CMOS sensor. 2. An IDE Cable. 3. A reference design CD-ROM. Figure 1.1. The TRDB_DC2 (DC2) Package Content (not including CD-ROM) 1 About the Kit Assemble the Camera 1-2 Please follow the four steps below to assemble your camera: 1. For Altera DE2/DE1 board users, assemble the CMOS sensor lens into the st 1 Sensor Connector (Sensor1-U1) on the DC2 board, as shown in Figure 1.2. 2. For TREX-C1 users, assemble the CMOS sensor lens into the 2 nd Sensor Connector (Sensor2-U2) on the DC2 board. NEVER use connector U1 for TREX-C1. The CMOS Sensor will be permanently damaged if you connect the CMOS sensor to U1 for TREX-C1. 3. Connect the IDE cable to the back of the DC2 board, as shown in Figure 1.3. 4. Connect the other end of the IDE cable to your DE2/DE1 or TREX C1 board as shown in Figure 1.4 and Figure 1.5, respectively. Figure 1.2 Connect the Sensor to “SENSOR1 U1” ( For DE2/DE2 Users ONLY) Figure 1.3 Connect the IDE cable to the back of DC2 board 2 About the Kit Figure 1.4 Connect the other end of IDE cable to the DE2/DE1 board’s expansion port (outermost port). Figure 1.5 Connect the other end of the IDE cable to the TREX C1’s expansion port (outermost). 3 About the Kit Getting Help 1-3 Here are some places to get help if you encounter any problem:

Features 2-1 The DC2 kit is designed using the same strict design and layout practices used in high-end consumer products. The feature set is listed below: 1. Support exposure time controlling – users can adjust the exposure according to the light of the surrounding area. 2. Support motion capture mode. 3. Software allows users to upload the picture captured into a PC and save the picture into bitmap format for viewing. 4. Equipped with iMagic C1M1D compact camera module. 5. Provide users entire reference design (Frame Grabber, high-performance multi-port SDRAM frame buffer, image processing IPs). 6. Support both Altera DE2/DE1 board and Terasic TREX-C1 Boards with the following camera locations: Board Sensor 1 Sensor 2 Altera DE2 Supported Supported Altera DE1 Supported(1) Supported(1) Not Supported Supported(1) (aks Altera Cyclone II Starter Kit) Terasic T-Rex C1 Note (1): Unlike DE2 boards which have SXGA output, DE1 and TREX-C1 boards, with only 4-bit VGA output, should use TRDB_LCM (3.6”Digital LCD Panel) as output device if high-quality image displaying is desired. 5 TRDB_DC2 Schematic of the Board 2-2 Figure 2.1.

Users can follow the instructions in this chapter to build a 1.3Mega Pixel camera using their DE2/DE1/TREX-C1 in 5 mins. Demonstration Setup 3-1 The Demonstration configuration is illustrated in Figure 3.1. The image raw data is sent from TRDB_DC2 to the DE2/DE1/TR1(TREX-C1) boards. The FPGA on the DE2/DE1/TR1 board is handling image processing part and converts the data to RGB format to display on the VGA monitor. The image captured at SDRAM can be taken at anytime (snapshot) and uploaded to a PC as a bitmap file. Figure 3.1. The Digital Camera Demo configuration setup 8 Digital Camera Design Demonstration Configuring the Camera (DE2 Board Users) 3-2 Locate the project directory from the CD-ROM included and follow the steps below: Quartus II Project Directory: DE2_CCD FPGA Bitstream Used: DE2_CCD.sof or DE2_CCD.pof 1. Ensure the connection is made correctly as shown in Figure 3.2. Make sure the IDE cable is connected to JP2 of the DE2 board. 2. Download the bitstream (DE2_CCD.sof/pof) to the DE2 board. 3. Connect the VGA output of the DE2 board to a VGA monitor. 4. Set toggle switches SW10 and SW9 to ON(UP position); set the other switches to OFF(DOWN position) 5. Press KEY0 on the DE2 board to reset the circuit. 6. You can press KEY3 to switch to the FREE RUN mode and you should be able to see whatever the camera sees on the VGA display. 7. Press KEY2 to take a shot of the photo; you can press KEY3 again to switch back to FREE RUN mode. 8. If you find the image shown on the display is too dark, you can increase the exposure time by changing the SW[15:0] to a larger binary number – you should start from changing SW8 to ONE. Remember to press KEY1 to reload the new exposure value defined by SW[15:0] 9. If the room is very dark, you might need to set SW11 to ONE (very long exposure time). 10.
