              {
               while(!T0IF);
               T0IF=0;
                count++;
               if(count==15)
                {
                  PORTB.F2=1;
                Delay_ms(500);
                 count=0;
                 PORTB.F2=0;
}}}}

I m getting the error ->

"Assigning to non-value[T0IF]"

Not sure what the "while(!TOIF);" is doing-something doesn't look right there. Is that a variable that gets modified by some interrupt process, or what? Is this a PIC? A little more information would help.

It's a lot easier to read if you put it inside code tags!

As Barry points out, it is usual to do something after a 'while' statement. Are you just waiting for T0IF to be non-zero before continuing? If that is the case try putting { } after the while(!T0IF) and before the ; in case the compiler is objecting to no code being present. The error message does seem to suggest that T0IF is not a variable though, should it be "<a register name>.T0IF" in the same way you have specified port bits?

Brian.

hi guys

thanks for the reply..
i have found the answer..
this is PIC16F877A
and i m trying to watch timer 0 interrupt flag bit.. its is not T0IF, it is TMR0IF..
i typed INTCON.F2 instead of TMR0IF..
its compiling now..


Thanks
