Video with a micro controller

Former Member

Hello, I am looking for a video camera I ca use with the AVR xmega microcontrollers. I want to save video onto an sd card an occasionally pull a still and send it over uart to another controller that will then send it wirelessly via Xbee. I have looked at several of the options on sparkfun and can't find enough information out there about how doable this is. I also want to look at using a usb webcam either using the lufa framework of bypassing the usb and capturing the video from somewhere else on the board. Of course this would be highly dependent on the webcam I use(probably one from one of those broken laptops under the desk over there). Anyone have experience hacking webcams?

  • Most micros aren't really suited to do video tasks.  FPGA's are a better fit because of their speed and ease of memory creation/access.

     

    Also, using USB isn't real easy to implement for complex devices, especially with something that probably used proprietary windows drivers in the first place.

  • Hello, have you so far achieve your goal ?  Did you make some experiments with microcontrolers and cameras?   Could you tell me your progress?   I think it would be faster but not easier to use a FPGA, but probably you could use in lue of a crystal to oscillate and discharge the camera, you could discharge that by a pulse generate by a microcontroller and the record in a SD frame by frame.   Share your thoughts, I would like to do something similar image
