Code Composer Error #552-D

Other Parts Discussed in Thread: MSP430G2553

I am using a LaunchPad with a MSP430G2553 and Code Composer 5.5. I continually get a error about a variable being declared, but unused, even though the variable is used on the next line of code.

I have simplified my code in an attempt to locate the error. Any help is appreciated!!

#include <msp430.h>
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int main(void)
{

const char str[] = "4321";
int value = -1;

value = atoi(str);
}

Error Received
#552-D variable "value" was set but never used

Hello,
I see that you are setting "value" to the return value of atoi(str). But I don't see where "value" is actually used. Setting a variable to a value is not the same as "using" it.

Thanks

Here is the actual code I am trying to make work. Value is supposed to be given in the atoi conversion in the last few lines. Messages[2] is equal to 1, but the atoi does not occur.

Thanks,
Bernard

when I compile the above code, I get a warning about 'stringValue', not 'value'. Did you mean 'stringValue'?
