I am using the ADV7179 to convert digital imagery to generate a composite video base band signal. We are configured to utilize Mode 0 (CCIR-656): Slave Option.
We are currently getting imagery out of the system. However, the imagery is monochrome only. We believe we are configured for color output. Viewing the signal on an oscilloscope showed me what I would expect for a monochrome signal.
We have the mode registers configured as follows:
Mode Register 1 = 0x38
Mode Register 2 = 0x00
Mode Register 3 = 0x00
Mode Register 4 = 0x10
