OV7670



  • Will the onion omega 2 be able to handle an ov7670 camera (No fifo)? If so will code be released???



  • There is no MIPI bus for camera interface.
    That should be the end of the story.

  • Indeed, look at USB cameras instead. Potentially less computational load as they often do mjpeg on-board.



  • @ccs-hello Even though there is no MPI bus, you can get the ov7670 working with an arduino using just the pins.



  • Most common MIPI bus' clock rate is 2.5Gbps.
    It is out of the league of GPIO bus.

    No, in fact, you cannot - intermediate hardware is required:

    or the host that doesn’t have a dedicate camera interface, additional hardware is needed. User need to buffer a entire frame before read them out with low speed MCUs.

    To use this with an Omega2, you would need something not far off of the hardware buffer required to use it with an Arduino. And potentially even moreso, as a full-featured operating system like Linux likely has greater interrupt latency than a simple MCU like an Arduino's ATmega.

    Fast in the sense of "getting a lot of stuff done per average amount of time" is very different from fast in the sense of "getting simple things done exactly when needed". Linux is good at the former, while an ATmega is good at the latter.
