Bug with variables allocation??

[Maverick]

I had a problem recently and found a solution to resolve it.
But I still have question on my mind.

The problem was like this:

I was formating a float into a string with sprintf and was sending each char to an LCD with a for loop .

sprintf( sBuffer, "\f%2.2fAE" , fCurrent );
for ( i=0 ;sBuffer[i]!='E' ;i++)
{
lcd_putc(sBuffer[i]);
}

It works first and was showing 0.00A to the lcd, (it is a current monitor).

But until recently I added some variables to the project and it stops to work! It's like the for loop wasnt able to see the 'E' at the end of the formatted string to end the loop and it was showing craps on my lcd.

The order of my variables in the file were like this:

int
long
float
char sBuffer[8]

To resolve the problem I changed the order of the variable, so now its

char sBuffer[8]
float
long
int

Can someone tell me if its a bug of CCS or something else??
I use version 3.129 of CCS. Thx

Not sure on your problem, but since you are dealing with a string it has a NULL terminator. so the 'E' is not needed. You can just simply check for 0.

Missed the form feed. Any value 10.0 and over will cause problems. Also note that the size of the array should be allocated depending on the largest value for fCurrent. 9 would work okay up to 99.99 but fail on 100.00. Of course, I doubt your current is that high.
