Dear Jenny,
If you look to the signal page (list of names) of the signals you can see that
y0 to y7 go to the camera. This is the parallel camera bus and cannot be used
for generic extensions. It can be used to connect other cameras. To connect an
extension the most elegant way is the i2c bus, but you can also use some direct
pins of the processor by removing the existing functionality. This can be done
on the signals that go and come back from the extension (top connector on the
extension connector pages). Using the i2c bus you do not remove
functionalities, but you need a device on the extension supporting the bus.
There is no doc about how to make an extension....
I hope this helps.
