Image Configuration Example
The following commands can be inserted into
the initialization sequence to configure the
camera for 16-bit RGB565 output and
1600x1200 resolution in video capture mode.
Note that most of these parameters are driver
variables and can be accessed as described in
the
Control Interface section above.
1. V[0x2797] = 0x0030; Context B output
format RGB565
2. V[0x2707] = 0x0640; Output width 1600
3. V[0x2709] = 0x04B0; Output height
1200
4. V[0x275F] = 0x0000; Crop X0 0
5. V[0x2763] = 0x0000; Crop Y0 0
6. V[0x2761] = 0x0640; Crop X1 1600
7. V[0x2765] = 0x04B0; Crop X1 1200
8. V[0x2741] = 0x0169; Auto
exposure/gain fix
9. V[0xA120] = 0x00F2; Auto White
Balance, Auto Exposure, Auto
Histogram, Video On in Capture mode
10. V[0xA103] = 0x0002; Sequencer
Refresh Mode
11. Read V[0xA103] until == 0x0000,
meaning the command got executed.
VHDCI Connector
The VmodCAM should only be attached to the
system board once the signals driven by the
system board are defined.
CAM1 refers to IC2, the camera on the lower
part of the PCB.
CAM2 refers to IC6, the camera on the upper
part of the PCB.
