Micro-manager guru Kyle M. Douglass recently posed his implementation of micro-manager on a raspberry Pi 3. Very cool potential here, considering when the computing power of the pi is exceeded for a given application, one could just add more for $45!
I’d imagine that memory handling issues related to image capture would be the biggest problem for the rpi, but it wouldn’t be surprising to see that addressed in the future. It looks like accessing cameras such as the point grey chamelion has been accomplished, however over 1394, not USB.
