Sprintf
PostPosted: Wed May 19, 2010 11:51 pm     Reply with quote
Quick question..

My C skills is somewhat incomplete on print functions.


This code works .
Code:

    sprintf(msg,"hello");
    print(3,0,msg);


Code:

void print(int x, int y,char* msg)
{
   
    setCursorAddress(((x*37)+y)-37);
    printf (Glcd_PutC, msg) ;
}



I would like to eliminate the first line sprintf(msg."hello") and replace it with print(3,0,"hello") or print(4,1, data)

Can some one point me to the right direction here.
compiler 4.105
Thanks

You can tell the compiler to pass strings to functions in an internal
temporary RAM buffer by adding the statement shown in bold below:
Quote:

#include <18F452.h>
#device PASS_STRINGS=IN_RAM
#fuses XT,NOWDT,PUT,BROWNOUT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

Then you don't need the sprintf().
