I thought to get a new forum rolling for this topic. People have touched upon it in some forums.
1. Streaming real-time camera images from Raspberry PI on the Arducopter
2. WiFi support of data from Rasp PI
3. User extension to RaspPI (i.e. user can interface say a camera of his choice and can read other interesting data (say, interfaced sensors) on the Mission Planner.
4. Encoding of camera images on the RaspPi and send to ground station. (Windows support too).
People, could you please share your inputs on usage/experience with Raspberry PI with the APM/ Arducopter?
