Demonstration Source Code
Project directory: tPad_Camera
Bit stream used: tPad_Camera.sof
Demonstration Batch File
Demo Batch File Folder: tPad_Camera\demo_batch
The demo batch file includes the following files:
Batch File: tPad_Camera.bat
FPGA Configure File: tPad_Camera.sof
Demonstration Setup
Load the bit stream into FPGA by execute the batch file „tPad_Camera.bat‟ under
tPad_Camera\demo_batch\ folder
The system enters the
FREE RUN
mode automatically. Press
KEY[0]
on the DE2-115 board
to reset the circuit
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 LCD
display
User can use the
SW[0]
and
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
User can use SW[17] to mirror image of the line. However, remember to press KEY[0] after
toggle SW[17]
Note: execute the
tPad_Camera
.bat under
tPad_Camera
\demo_batch will automatically
download the .sof file.
