Hi David,
before all thank you for your help.
I tried to edit my files as you wrote, but I yet have problems.
I edited my nesc file as follows:
-----
#include "Timer.h"
#include "Hello.h" //<------ I included the header file here
module BlinkC
{
uses interface Timer<TMilli> as Timer0;
uses interface Timer<TMilli> as Timer1;
uses interface Timer<TMilli> as Timer2;
uses interface Leds;
uses interface Boot;
}
implementation
{
event void Boot.booted()
{
call Timer0.startPeriodic( 250 );
call Timer1.startPeriodic( 500 );
call Timer2.startPeriodic( 1000 );
}
event void Timer0.fired()
{
Hello(); //<-------------This is the function call to Hello()
//dbg("BlinkC", "Timer 0 fired @ %s.\n", sim_time_string());
//call Leds.led0Toggle();
}
--------
The C files are these:
-----------
//Hello.h
#ifndef HELLO_H
#define HELLO_H
void Hello();
#endif
---------
#include "Hello.h"
void Hello()
{
printf("\nHELLO!\n");
}
-------------
and my Makefile is the following:
COMPONENT=BlinkAppC
LDFLAGS = Hello.o
Hello.c: Hello.h
$(CC) -o Hello.o Hello.c
include $(MAKERULES)
---
where $(CC)... is "tabbed"
So, when I run "make micaz sim" this error occurs:
---------
[EMAIL PROTECTED]:/opt/tinyos-2.x/apps/ImportC$ make micaz sim
mkdir -p build/micaz
placing object files in build/micaz
writing XML schema to app.xml
compiling BlinkAppC to object file sim.o

gcc: Hello.o: No such file or directory
make: *** [sim-exe] Error 1

How can I solve the problem???
Thank you very much in advance for your precious help
