We are using a frame grabber to collect camera photon counts form an andor iXon 897. From the documentation (https://github.com/sinara-hw/Grabber/wiki), it seems like there is a limit on the number of ROI engines that is between 16 and 32. On some measurements, we'd like to access counts for more than 100 pixels, which would require over 100 ROI engines. Is there a way to increase the number of ROI engines, or is this fixed by the hardware?

It's FPGA gateware, so it can be increased, but at some point you will run out of FPGA resources or the design will fail timing.

Hi! Is there any way to grab all the individual pixel value as an array for a particular capture? I tried to define each pixel as a single ROI, bur it fails when the region is larger than 5X5 = 25 pixels.
Thanks in advance.
