simple 8 pi cameras testing for multi-camera adapter board for raspberry pi

could you please share the codes ?

The cameras all use the same settings resolution, frame rate, etc. What the board does is switch between the different outputs of the boards. As far as the raspberry pi is concerned there is only one camera connected. I recently purchased two of these boards (version 2) for the 8 mega pixel cameras. It appears that they had to pull a chip from the cameras in order to make them work with the board.

For my project I would like to use five cameras, but I am having a hard time getting the system to switch to the 5th camera. I assumed you had to populate the 10 pin riser to pass the data between the boards. The riser wasn't populated on this version. Is there some example code you can send multiple boards?
