Dear all,
I have some troubles implementing a parametrized interface of Timers. I have
used the code snippets from "Software design Patterns for Tinyos" from Gay et
al. and some hints online and from this mailing list. I am attaching the
complete code (it is basically the Blink application with an array of 3
timers). When compiling, the error is:
In component `BlinkC':
BlinkC.nc: In function `Boot.booted':
BlinkC.nc:51: Timers.startPeriodic not connected
BlinkC.nc:52: Timers.startPeriodic not connected
BlinkC.nc:53: Timers.startPeriodic not connected
make: *** [exe0] Error 1
I found a hint on this mailing list from Phil Lewis that I need a default
implementation for the event, but this hint leads to yet another compilation
error, saying:
In file included from BlinkAppC.nc:45:
In component `BlinkC':
BlinkC.nc:61: `fired' is defined, not used, in this component
BlinkC.nc:61: (default implementations are only for used commands or events)
BlinkC.nc:61: conflicting types for `Timers.fired'
BlinkC.nc:56: previous declaration of `Timers.fired'
make: *** [exe0] Error 1
I would be very thankful for any ideas of how to get this wokrking. And, yes, I
am sure I need such a parametrized interface (not for the Blink application, of
course.. ) :-)
