Problem with debusgging atoi function in MPLAB using PICKIT3

[flote21]

Hello people,

I am trying to convert an array of 2 characters into integer 16 bits usign atoi function but when I debug my program with MPLAB the int value is always 0. Is there any problem using this conversion functions?

PD; The compiler is XC8 => PIC18F4520.

Thanks!

post a piece of code did you pass a pointer or char directly ?

Hi thank you very much for your attention..This is the code and it does not work with the XC8 compiler.

unsigned char humidlcon_hum[2]={0x12,0x15};
unsigned int honeywell_hum;

honeywell_hum = atoi(humidlcon_hum);

unsigned char humidlcon_hum[2]={0x12,0x15};
unsigned int honeywell_hum;

honeywell_hum = atoi(humidlcon_hum);

The code can't work, at least for two reasons:
-the string is missing a terminating null
-0x12 and 0x15 aren't valid numeric characters

unsigned char humidlcon_hum[3]={0x32,0x35,0};
respectively
unsigned char humidlcon_hum[]= "25";

should work.
