Camera Demonstration Setup On DE2-115 Board
3.3
Locate the project directory from the CD-ROM included and follow the steps
below:
Directory: Demonstration / DE2_115_CAMERA
FPGA Bitstream Used: DE2_115_ CAMERA.sof
1.
Ensure the GPIO voltage level is set to 3.3V via JP6 (GPIO_VCCIO) of the
DE2-115 board.
2.
Ensure the connection is made correctly as shown in Figure 3.3. Make sure
the D5M is connected to JP5 (GPIO) of the DE2-115 board.
3.
Connect the VGA output of the DE2-115 board to a VGA monitor.
4.
Copy the directory DE2_115_D5M_VGA from D5M System CD-ROM to the
host computer.
5.
Download the bitstream (DE2_115_D5M_VGA.sof/pof) to the DE2_115
board.
6.
The system enters the FREE RUN mode automatically. Press KEY[0] on
the DE2-115 board to reset the circuit.
7.
Press KEY[2] to take a shot of the photo; you can press KEY[3] again to
switch back to FREE RUN mode and you should be able to see whatever
the camera captures on the VGA display..
8.
User can use the SW[0] with KEY[1] to set the exposure time for brightness
adjustment of the image captured. When SW[0] is set to Off, the brightness
of image will be increased as KEY[1] is pressed longer. If SW[0] is set to
On, the brightness of image will be decreased as KEY[1] is pressed shorter.
9.
Set the SW[16] to On (upper position), the captured image will be enlarged
with KEY[0] and KEY[3] pressed in order.
10. Table 3.2 summarizes the functional keys of the digital camera.
