#include works fine, but, as in C, it's just textual inclusion (it
really is nothing complicated ;-)). So it's all as if you just wrote:
module ...
implementation
{
#ifndef C_CODE
#define C_CODE
void Hello();
#endif
event void Boot.booted()
{
call Timer0.startPeriodic( 250 );
}
event void Timer0.fired()
{
Hello(); //Hello() is a function which is inside my C code
}
}
which therefore just declares Hello() as an internal function inside BlinkC.
In nesC, C functions must be declared before the module/implementation
(or interface) part of a file. So what you wanted to do was:
/* nesC code*/
#include "c_code.h"
module ...
implementation
{
event void Boot.booted()
{
call Timer0.startPeriodic( 250 );
}
event void Timer0.fired()
{
Hello(); //Hello() is a function which is inside my C code
}
}

Yes, you then also of course need to compile and link with your C
code. Several ways to do that... The easiest in this case at least is
probably to add
LDFLAGS = c_code.c
to your Makefile, which should cause ncc to compile and link c_code.c
with your nesC app. A slightly more traditional Makefile approach
would have you add
LDFLAGS = c_code.o
c_code.c: c_code.h
$(CC) -o c_code.o <your favourite flags> c_code.c
to your Makefile... (don't cut & paste the text above, the character
before $(CC) needs to be a tab to keep make happy, in this email it's
some spaces...)
