Yes, thanks. But in addition to this, I'm looking for the following info :
1) What are the GPIO pins used for ? Can we use them for analog video. 2) Are all the address/data pins required ? Are they bidirectional? What do we do with unused pins ? 3) Where do we put mounting holes on OGD1 ? 4) Apart from the address/data pins, what are all the other pin types used for.
