measuring pulses with "while" dosn´t work...

[fbiasoto]

I´m trying to use a while command to wait a logic level change. It does´t work.
I´m doing this:

bit level;
sbit RXTAG at P3.B4;
unsigned char f;



level=0
for(f=0;f<8;f++)
{
level=~level;
while(level==RXTAG){}
etc
etc
etc
}

the logic level of pin P3.4 changes but the software freeze on line while(level==RXTAG){}

Any sugestion?

Thanks

Try this:

while((!level) == (!RXTAG)){}

I wil try this.
I had solve the problem by myself.

For some reason while(RXTAG==level){}; does´t work, but while(level==RXTAG){}; works

Thanks CVMichael

Well, while((!level) == (!RXTAG)){} doesn´t work.
