Hello, Here is what I am looking for -- I would like to connect a video camera, a microphone, speakers and a micro SD card to a DSP. The DSP should have at least one serial port. Over the serial port it will receive the following commands -- 1. Record video to filename -- it should start recording the video to a file on the SD card. 2. Record audio to filename -- it should start recording the audio to the filename on the SD card 3. Play audio -- it should play the audio file stored on the SD card. The video will need to be compressed on the fly and the frame rate will be 30 fps. I want the simplest solution to this problem. Minimal cost and part count. Ideally I am looking for a sub $25 solution with minimal part count. Are DSPs the way to go. Which one of these things would you recommend. Is there an evaluation board I could get started with. I have never programmed a DSP but am familiar with microcontrollers and FPGAs. Thanks, Saleem _____________________________ Posted through www.DSPRelated.com

Then you can do basic video processing if you need to.

I would look around to see if there's an EVB out there that already does this. I'd be mildly astonished if that wasn't so, because it's such a common application in the wild. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com
