Using Automotive Grade Chip ADV7180wbst48z
Input YC (Pal_G from PC graphic ): input on Ain3 and Ain6
After config the registers as belowing, I got the ycrcb data stream.
I can detect the head signal and the end signal as ff 00 00 xx . (in chipscope )
But the valid data seems not right .they are 80 10 80 10 80 10 .....(repeat)
I know if i do not config the register 0x0c .its default value make the chip output a blue screem (free run mode ).
So i changed its value to 34.which disable its free run mode
But its remaining output the 80 10 80 10.....
anyone any suggestion on this issue .thank u !
