 		 #92065 - about the beer ...
Responding to: ???'s previous message
So the interrupt happens, thus forget the timer for now.


Done.

There are some strange things here are you sure it is not a watchdog or some such (a typical simulator "oversight") try a toggle pin at main() before the while(1), Ill bet you a beer at FrankA (easy when I am 3000 miles away) that it toggles.


Oh I hate this kind of bets ... By the time you set foot here, I've forgotten all about it ...

Save This Code
P1 ^= 0x40;

Just before while(1) - works, toggles the pin, which then drops to a "defined zero" state, pulled down by a resistor or some other device attached to ground (judging the slight hum).

By the way - what should this example prove?
