What Gerald is saying is that in general you should not expect to drive an LED directly - you will want to drive a transistor which can then supply perhaps 20 ma or more to your LED and at the correct voltage. Perhaps you are already doing this, but you didn't say.
I don't know anything about the Cloud 9 interface, but if is blinking by just using the shell (" echo 1 > pin whatever....) with "sleep", sleep may not recognize any increment of less than integral seconds. I'd look into that. Maybe see if it works for longer intervals like 3 or 5 seconds... Speaking strictly for me, when something doesn't work, 99.9% of the time it's something I did wrong, not the hardware etc. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
