Hi, im new here, and Im doing a proyect which happens that i need to change a string to integer.

On C eclipse works fine however on Freescale doesnt do anything.


Pleace help


I create a new proyect apart just to see ATOI working properly. I was able to see that the variable "number" changes from 4 to cero, as if nothing got atoi and if I uncoment the atof line i geet the error Symbol strtod ... is undefined.


Please advice (version of  my codewarrior is V6.3 build 9279

This is the code:


#include <hidef.h> /* for EnableInterrupts macro */

#include "derivative.h" /* include peripheral declarations */

#include <stdio.h>

#include <stdlib.h>

#include <string.h>


char y[] @0x0068 ="12";

char f[] @0x0070 ="143.343";


int number @0x0060 =4;

double flot;


void main(void) {


  EnableInterrupts; /* enable interrupts */

  /* include your code here */      

  for(;;) {

    __RESET_WATCHDOG(); /* feeds the dog */

      number=atoi((const char*)y);   /// also like this doesnt work : number=atoi(y);


     //flot = atof((const char*)f);


  } /* loop forever */

  /* please make sure that you never leave main */
