How do I enable EDID communications on the DDCA pins of the ADV7842 chip?
In my project, I have a logic analyzer on these pins to monitor the traffic. When I plug the DVI cable from a desktop PC to the board, the PC sends out an I2C message to these pins but the AD7842 chip does not respond.
Is there a configuration script I need to send to the ADV7842 chip upon power up of the board?
Also, how do I configure the AD7842 with the correct information to report back?
Any help is greatly appreciated.
