Abstract:


 1  The Neuros OSD is the first open source, Linux-based, embedded media center. It records video from any source and links your PC, entertainment center, and portables.
More info : WIKI

Power Consumption max 2A
Power Supply 5V DC

Added support to control by uC via serial line:
- start recording,
- stop recording,
- get status of recording
Status: DONE



 2  Insert some information over video ( MAX7456 ).
Control Neuros via serial line.
I2C interface to main controller
Get OBD information from main controller and put in over video from camera.
Status: (Jul/07/2009) DONE
