This is a guess, for your device,  but I suspect
something along these lines:

t = Ao_timer()

cb = t.after(100,thing_that_does_the_work(with_its_arguments))

Lots of assumptions here - the 100 should give you a tenth of a second...
Don't know what the arguments look like, and if you need to pass an instance 
(like self) - that would depend on where you are calling it from.

Play and see :-)

You should also be able to cancel the callback like this:


If you do it before the time out
