PPM pulsed from the signal generator.
As discussed before the Arduino will be producing the PPM pulse in-flight. The encoding uses 0-250 in byte to achieve stepped PPM time shift from 1ms to 2ms. This leaves 5 bytes to address separate motors, we have only 4, we might use the additional byte to trigger the camera or a parachute release output.
The current issue is getting a camera to work with a Verdex, we might have gone with an entirely separate camera subsystem, but that makes it difficult to syncronize the clocks. A USB camera attached to the Gumstix will have to do for now, they are cheaper and lighter than a full camera. The lightest option will be a phone style integrated camera but that can wait.
tutorial. WorldWind now has shapefile support as well, making mission planning easier. Only if we had a quad as big as the one I rendered.
