I am using ADV7180 for capturing from a S-Video interface connected to AIN1 in a custom board with a TI processor.
I am using the following register settings for ADV7180 which I got from ADV7180 Design Support Files from the site ADV7180 Design Support Files .
42 00 00 ; INSEL = CVBS in on AIn 1
42 04 57 ; Enable SFL
42 17 41 ; select SH1
42 31 02 ; Clears NEWAV_MODE, SAV/EAV to suit ADV video encoders
42 3D A2 ; MWE Enable Manual Window, Colour Kill Threshold to 2
42 3E 6A ; BLM optimisation
42 3F A0 ; BGB
42 0E 80 ; ADI Recommended Write
42 55 81 ; ADI Recommended Write
But after using these values to set ADV7180 I am not getting any signal on the Hsync pin when I probe it using oscilloscope. The read and write operation on ADV are working fine.
Can you tell me if I have to set any more register for setting the ADV chip? And how to know if the input to the ADV chip is coming fine?
