Tool/software: Code Composer Studio
Hello,
I am having an issue with array declaration in my project. I found that after element assignment, the array element values are not actually changing rather showing (-1) for all! Here I am pasting a rough code to clarify the problem:
#include <msp430.h>
#include <stdio.h>
#include <stdint.h>
void main (void)
{ int i, j, k,l,m,n;
float y[211], out [211];
int in[211] = {4095, 4095, 4095, 4095, 4095, 4095, 4095, 4095, ----------------> Like here at in[] array none of the value is assigned, all are (-1)
4095, 4095, 4095, 4095, 4095, 4095, 4095, 4095,
4095, 4095, 4095, 4095, 4095, 4095, 4095, 4095,
4095, 4095, 4095, 4095, 4090, 4095, 3920, 4095,
3754, 4095, 3608, 4095, 3412, 4095, 3306, 4095,
3144, 4095, 3044, 4086, 2974, 4032, 2950, 3972,

2368, 2880, 2423, 2752, 2504, 2656, 2608, 2554,

int BPcoef[211] = {-3, -6, -8, 6, 34, 49, 34, 6, -8, -6, -3};
WDTCTL = WDTPW| WDTHOLD;
for (j=11; j<211; j++ )
{
BPcoef[j]= 0;
}
for (k=201; j<211; k++ )
{
in[k]= 0;
}
for (l=0; l<211; l++ )
{
out[l] = 0;
for (m=0; m<l;m++)
{
out[l] += ((in[m]*2.5)/4095)* BPcoef[l-m];
}
}
for (n=0; n<211; n++ )
{
y[n]=out [n];
}
}
Thanks.
