Full Version: Can I remap Pulpissimo pads to connect a camera on Genesys2 fpga board?

Hi,

I want to connect a camera to Pulpissimo's Camera Interface (CPI) on Genesys2 board.  However, most CPI pads are connected to LEDs/buttons/switches on Genesys2 board.  Can I modify the constraints file to remap and connect the CPI signals to the FMC connector so that I can use Digilent FMC Pcam Adapter to connect camera modules?  Any considerations I need to take ?

Thanks,

That should not be an issue.. AFAIK, CPI is not a very well defined standard, so some tweaking might be necessary to adapt to the specific camera you are using. If you have a good mapping/solution, it would be great if you could make a PR to contribute to the repo.

After studying the details of Digilent FMC Pcam Adapter, I found it uses MIPI CSI-2 interface, not CPI and it needs much more pads for differential signals.   Replacing the CPI module  in Pulpissimo with a MIPI CSI receiver seems be much more than just a tweaking task. Any suggestions ?

Thanks,
