Hello I have a problem with converting int to char.

I don't have access to extras.h

And sprintf only givs back junk characters

I have also tried the union example that is placed here on the forum but no success

I have just simplefied the function to see what is going wrong but the problem is still there

void itoa() {
unsigned int n = 12345;
unsigned char i = 0;
unsigned char s[7];

RS232_Enable();

do {
s[i++] = (unsigned char)('0' + (n % 10)); // This works givs 54321 on RS232 or on LCD

do{}while(RS232_SendChar(s[i-1]));

} while ((n /= 10) > 0);

s[i] = '\n';

for(i=0;i<5;i++){
do{}while(RS232_SendChar(s[i])); // This doesent givs X4X2X where X is random
}
}

And if i declare s[7] as static char i get 5X3X1 where X is random

What am I doing wrong?

I use a 56F8357 and CW 8.1.1a build 7168

Hope someone could give me a helping hand because this is not what I should spend my time on.
