I am using ADV7180 in a video capture project.
My cammera`s output is PAL 720*544 which i want to connect to ADV7180.
I connect ADV7180 chip to Xilinx Spartan3 FPGA and program its registers via I2C.
i have a problem when i connect my cammera to ADV7180.
the problem is that when i check stus register 0x10 data, Fsc lock bit some times is high and some times is low., means not locked.
alos when i reset chip via I2C , teh chip stays at reset state and does not work more.
please help me how can i check that my cammera`s video is detected by ADV7180 correctly or not.( I have not video encoder)
