PCAM interfacing with zedboard

[jayasha]

Hi, I have interfaced PCAM with zedboard as per the instructions given in https://digilent.com/reference/programmable-logic/zedboard/demos/fmc-pcam, its working fine . But next, I want to capture and store some images. Can anybody help me in clarifying further steps for this. How to know which IPs are required for this process?

It depends on how you want to store data - if you want to grab and manipulate a frame in DDR, since the frames are already moving through DDR, this is possible with minor software changes only. You could also potentially dump image data out to an external application for further processing using UART (which would be slow) or ethernet. Writing an image from DDR to a file system, on, for example, an SD card, would also be possible - it requires having software access to the file system, which could potentially be done using additional libraries in baremetal, or by replicating the entire system using PetaLinux.

Thanks,

Firstly, thanks for your response. Does it mean that I have to make some changes in "main.c" in Vitis for saving a frame in DDR and there is no need of editing IP block design?

Hi @jayasha

Yes, saving and processing images in software should be possible without modifications to the Vivado project.

Thanks,
