Problem with Arrays

Hi All,

I have 2 loops in my code. One loop that fills an array, the other loop prints it out. See code below. If I take out the array and output the numbers as I get them, I get the data I expect; but with the array, I get a data stream that is shaped like "saw wave" out. Why is the data not consistent? What am I doing wrong?

What is the type of I and I3? Are they both unsigned int16?

Can you post more of your code where you define the array?

refining my problem. I start going step by step. I run into the problem when i use a 16bit array. My input doesn't match my output.

#include <prototype.h>

void Main()
{
unsigned int16 data[6];
unsigned int16 i;
unsigned int8 temp1, temp2;

while(true)
{

for (i=0; i<=4; i++)
{
temp1=getc();
temp2=getc();
data[i]=(make16(temp1, temp2));
printf(" %u ",i);
}

printf("\n\r output from array\n\r");

for (i=0; i<=4; i++)
{
temp1=make8(data[i],0);
putc(temp1);
temp1=make8(data[i],1);
putc(temp1);
}
}
}

iF I input 444444
i get this out.

0 1 2 3 4
output from array
4\4^4`4b4d
