>WRONG!


As usual there are a number of ways to implement any given task.
I must have misunderstood, I thought he was referring to a single LED
In any case, using a timer int to provide an opsys "tick" to pace I/O
functions is perfectly
valid, and works just fine.  I suppose you could do it without ints, but if
you want to have
deterministic time intervals, that is certainly the hard way.

Perhaps we are talking about the same thing, but describing it differently?
