Hi, I have an application where the micro controller LPC932 is waiting for a momentary push button to be pressed. I know there should be some time (msec.) to avoid false readings caused by bouncing. I am not using an interrupt in this procedure and I have no timers available. What will be a good approach to avoid this bouncing after pushing the button?
I am thinking something like this could work, but I would like to hear any other suggestions.

Thanks

// do other tasks.

while (pushb != 0); // wait until button is
// pressed

// wait for about 40 msec. to avoid any double
// counting due to contact bouncing

// continue with other tasks
