Actually it won't work that way.
Configuration file is static. Once you wire it, you wire it.
you can not put "if" statement in conf.
TOS_LOCAL_ADDRESS need to be judged in StdControl.ini() in the wrapper
module.
I think I figure out the solution. Take CntToRfm & RfmToLeds for an exmaple.
configuration CntToRfm {
}
implementation {
components Main, Counter, IntToRfm, TimerC;
Main.StdControl -> Counter.StdControl;
Main.StdControl -> IntToRfm.StdControl;
Counter.Timer -> TimerC.Timer[unique("Timer")];
Counter.IntOutput -> IntToRfm.IntOutput;
}
--------
configuration RfmToLeds {
}
implementation {
components Main, RfmToInt, IntToLeds;
Main.StdControl -> IntToLeds.StdControl;
Main.StdControl -> RfmToInt.StdControl;
RfmToInt.IntOutput -> IntToLeds.IntOutput;
}
------
above are original conf. files
I changed them to:
configuration CntToRfm {
provides interface StdControl;
}
implementation {
components Counter, IntToRfm, TimerC;
StdControl = Counter.StdControl;
StdControl = IntToRfm.StdControl;
Counter.Timer -> TimerC.Timer[unique("Timer")];
Counter.IntOutput -> IntToRfm.IntOutput;
}
-------
configuration RfmToLeds {
provides interface StdControl;
}
implementation {
components RfmToInt, IntToLeds;
StdControl = IntToLeds.StdControl;
StdControl = RfmToInt.StdControl;
RfmToInt.IntOutput -> IntToLeds.IntOutput;
}
-------
In the wrapper conf. file, I put:
configuration Wrapper
{}
implementation
{ components Main, WrapperM, CntToRfm, RfmToLeds;
Main.StdControl->WrapperM.StdControl;
WrapperM.FstControl->CntToRfm.StdControl;
WrapperM.SndControl->RfmToLeds.StdControl;
}
----------
The WrapperM module is the real place where different components are
initialized at run time according to local_addr:
module WrapperM
{provides
{ interface StdControl;
}
uses
{interface StdControl as FstControl;
interface StdControl as SndControl;
// interface StdControl as TrdControl;
}
}
implementation
{
command result_t StdControl.init()
{
dbg(DBG_USR1, "WrapperM initializing.\n");
if (TOS_LOCAL_ADDRESS==0)
return (call FstControl.init());
else if ((TOS_LOCAL_ADDRESS==1))
return (call SndControl.init());
// else if ((TOS_LOCAL_ADDRESS==2))
// return (call TrdControl.init());
else
{dbg(DBG_USR1, "local addr=%i, initializ nothing\n",
TOS_LOCAL_ADDRESS);
//return 0;
}
return SUCCESS;
}
command result_t StdControl.start()
{
dbg(DBG_USR1, "WrapperM initializing.\n");
if (TOS_LOCAL_ADDRESS==0)
return (call FstControl.start());
else if ((TOS_LOCAL_ADDRESS==1))
return (call SndControl.start());
// else if ((TOS_LOCAL_ADDRESS==2))
// return (call TrdControl.start());
else
{dbg(DBG_USR1, "local addr=%i, initializ nothing\n",
TOS_LOCAL_ADDRESS);
//return 0;
}
return SUCCESS;
}
command result_t StdControl.stop()
{
dbg(DBG_USR1, "WrapperM initializing.\n");
if (TOS_LOCAL_ADDRESS==0)
return (call FstControl.stop());
else if ((TOS_LOCAL_ADDRESS==1))
return (call SndControl.stop());
// else if ((TOS_LOCAL_ADDRESS==2))
// return (call TrdControl.stop());
else
{dbg(DBG_USR1, "local addr=%i, initializ nothing\n",
TOS_LOCAL_ADDRESS);
//return 0;
}
return SUCCESS;
}
}
-------
Because it is for 2 aplications simulation, so I commented out
TOS_LOCAL_ADDRESS==2 part, which is for more applications.
Just put new CntToRfm, RfmToLeds, Wrapper, WrapperM in one folder with
"COMPONENT=Wrapper"in the makefile. It will do.
Many thanks to Joe for the hint in previous post.
comments are welcomed.
Happy Valentine!
