How complicated is it to get a AV signal from a FPV camera and feed the video data into a UART port?
Will i need to digitise the signal through a microprosessor?
Thanks for you help
Hmm, unless I am not understanding your question, the answer is you can't.
Are you asking if you can simply wire an analog video signal to a microcontroller uart port?
To capture a analog video signal, you will need a video capture device that captures analog video and converts it into a digital video stream.
But like Razor said, one you start dealing with digital video, most microcontrollers used around here are not going to cut it.
