How to capture 1 channel CIF video?

Other Parts Discussed in Thread: TVP5158

Hi:

Our hardware platform is DM6467+TVP5158, and I want to capture 1 channel CIF only,

but after set some TVP5158 and VPIF registers, it still did not work! And I can't find relative

example code.

Who can tell me how can I do it?

What registers of TVP5158 and VPIF should be set, and the value of them?

Thanks a lot!

Hello Zhouger,

The TVP5158 cannot be configure as 1 CH CIF output. You can only configure it at 4 CH CIF with I2C register B0h.

Hi, Viet:

Does TVP5158 cannot be configure as 1 CH Half-D1 output too?

Hello Zhouger,

For 1-Ch Half-D1 output mode, write 02h to I2C address B0h.

For 1-Ch CIF output mode, write 03h to I2C address B0h.

With these output formats, each byte is repeated to maintain a 27MHz output clock.

Also, these two output formats are not tested or supported.

Regards,

Jim
