ADV3205 EV problems

Question asked by clunk76 on Mar 18, 2014

I have purchased an A03250 evaluation kit in order to begin interfacing with an ADV3205, and have connected +5v to AVCC and DVCC, and -5v to AVEE.

 

With a USB cable connected and the provided test software, the IC switches video perfectly, but when I connect an external micro-controller to the DATA_IN, UPDATE, CE, CLK and RESET pins (with the SUB disconnected) and attempt to perform a simple switch in serial mode, I am getting no video at all. The data and timing viewed on those pins from a logic analyser looks identical when it is sent from my micro-controller than when the provided test application sends the switch.

 

I am going to try communicating in parallel mode as I'm rapidly running out of ideas but if anyone can help with any suggestion then that would be

great as serial mode is far preferred.

Any help will be greatly appreciated, thanks in advance.
