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.
