Can I remap Pulpissimo pads to connect a camera on Genesys2 fpga board? - tparng - 01-07-2023
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.
Cheers,

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 ?
