I think you need to assume that pretty much anything can happen while the board is booting or crashing, and inhibit all servo activities unless you know the BBB is in positive control.
Depending on how "large" your fixed-wing is, it probably would not be a bad idea to put some kind of watch-dog timer in the system, so that if the software crashes/stops/looses-interest/reboots/low-battery/ the servos all go to some neutral/safe setting. --- Graham == -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
