All,
Just posted a video up on a couple of changes that I have made to the rushduino OSD code. I have added multi camera switching support and also added a sonar array. You can switch between the standard OSD and the sonar array display. The distances displayed are in cm and the length of the line relative to the distance measured. Max range is set to 4m. The raw sensor values can be turned off to just leave the distance bars. Still a bit of work to complete on it but thought I would post a quick video.
