Multiplexer for Pi Camera Module

rboone2020

Hello,

 

I am new to element14, and appreciate your help.   I am a wildlife ecologist interested in surveying wildlife and livestock.   I am experimenting with a Raspberry Pi with a camera and a stepper motor to take panoramic images every minute or so.  Enjoying the process, but ...

 

Ideally I would prefer a solid state solution.   I would like to connect 8 Pi cameras to a single computer.   **I do not need signal from all of them at the same time**   I just need to pole each camera in turn.   I think I need a multiplexer, but a design ... or even the chip in question ... is beyond me.   Do you have any pointers?   Are there places on the web where I might contract with a designer for an embarrassingly small amount of money to help out?

 

As I say, new to the community.  If this post is misplaced, pardon.

 

Thanks,

Randy

    Hi,

     

    It seems I've stumped folks.   The technical question aside, is there a good place on the web to post requests for design assistance?

     

    Thanks,

    Randy

    Hi Randall,

     

    This is quite some work, because the cameras operate at high speed, and without a lot of knowledge of what is going on, perhaps an FPGA or CPLD might be the route you may want to pursue - just guessing though, I am not knowledgeable on the camera. It may be LVDS interface to the camera, so then you need a device with LVDS capability. It would need a custom board made too (you couldn't use prototyping board). So, it is a fair amount of work for an Engineer, maybe several weeks : ( I'm not sure there is anything existing that could be re-used to reduce the amount of development. I don't know if the circuit diags are published for the camera - if they are, that may help you.
