little change in input.c in example file gives error
PostPosted: Sat Dec 28, 2013 12:47 am     Reply with quote
hi i've compiled the input.c as here
Code:

#include<18f2550.h>
#include<stdlib.h>
#fuses NOWDT,HS,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,INVERT,parity=N,bits=8)
//#ifndef __INPUT_C__
//#define __INPUT_C__

#include <string.h>

#endif

#endif   //_STDLIB

#endif   //__INPUT_C__//error high lights here

The error is line 274[2,7] expecting function name
Can you tell me how to fix this ?

You have no main() function. That's the reason.

Also, don't try to compile CCS driver files as a "program". They are
intended to be added to your main program with an #include statement.
Also, in the general case, do not edit CCS driver files.
