I'm new in arduino and have a question about using spi and v7670 camera. It would be appreciated if you let me know whether the following is possible.
I have a plan to use ov7670 camera module with my arduino. After taking image with the camera the I want to send it to my beagle bone black via spi interface. I know that it is possible to make such connection. But the issue is this. I would send some signal from the beagle bone to the arduino and then the arduino would take images. For example, if a temperature sensor connected to the beagle bone black reads 30 degree, the arduino has to take image with v7670. Would it be possible?
By using UART port and TTL communication it seems okay. But how about spi?
Thank you
