How to convert ASCII characters into numeric values in KEIL COMPILER.
 

keil ascii to character

if you want to convert a single character :

Code: 
char c = '5';
int a = c - '0'; // now a = 5

if you want to convert an ascii array:
Code: 
int a = 0;
char num[] = {'1' , '9' , '3' };

a = conv( num , 3 ); // now ans=193
.
.
.
int conv( char arr[] , char len )
{
    int ans = 0;
    char i;
    for( i = 0 ; i < len; i++ )
    {
        ans *= 10;
        ans += arr[i]-'0';
    }
    return ans;
}

Hi,

I think you can try to use the fomula.
Code: 
No = No * 10 + ch - '0';
Good Luck.
