I have checked in the following 3 new modules/interfaces into tinyos-1.x
main tree. Timer, AbsoluteTimer, LogicalTime and SysTime.
The new Timer module replaces the old Timer.
The new Timer module has a totally difference implementation.
It is build on top of AbsoluteTimer. The following simple diagram shows
the dependency of these modules:
-----------------
Timer
-----------------
AbsoluteTimer
-----------------
LogicalTime
-----------------
Clock | SysTime
-----------------
As a result any application that uses existing Timer will have the above
modules wired in transparently.
The new Timer requires that Timer.StdControl.init and
Timer.StdControl.start
Commands are called before Timer.start(). If your application timer does
not work, this is the first place to check.
Other issues:
=============
1. We have not yet simulate the read/write registers used in SysTime
properly. But you should be able to compile the simulator.
If make pc fails, please get latest tos/platform/pc/SysTimeC.nc file.
2. Mica motes misses clock interrupt from time to time. I can not
eliminate it because they are caused by HW and interrupt queue
length(1). But I am working on to reduce the frequency it happens and
its impact.
Bug report:
===========
