Hi,

 

I am using a embeded system running linux.

Using a PAL security camera as an input, I get a image but it seems to be out of sync.

see attached images (one was with using the embedded sync and the other with hardware sync lines).

 

I write the following to the i2c registers:

 

INSEL = Composite AIN4: 0x00, 0x03

Enable SFL: 0x04, 0x57

Select SH1: 0x17, 0x01

Clear NEWAV_MODE, SAV/EAV to suit ADV encoders: 0x31, 0x02

MWE enable manual window, color kill threshold to 2: 0x3D, 0xA2

BLM optimization: 0x3E, 0x6A

RGB optimization: 0x3F, 0xA0

Hidden Space: 0x0E, 0x80

ADC configuration: 0x55, 0x81

User Space: 0x0E, 0x00

 

I also read Status registers:

 

STATUS1: 4b

STATUS2: 10

STATUS3: 6d

 

Is this due to the Nonstandard line lentgth detected?

 

Any ideas or pointers will be apriciated.

 

Thnaks,

lhrossouw
