Talk:Modules and the TinyOS Execution Model

In TinyOS 1 I agree that Timer interface is correctly in tos/interfaces/Timer.nc but, in TinyOS 2, where is it? I think it should be remarked that is the file in tos/lib/timer/Timer.nc. Am I right?

When I try to compile this example it tells me that Leds.ledxOff() and Leds.ledxOn() do not exist...
