AVR-Chat

Someone (John Samperi?) asked how long I had waited to see if interrupts 
were happening.  The answer is a very long time. I even went so far as 
to set the program to running, and going off to do other things for 
almost an hour.  I returned to find the program still cycling rapidly 
between rjmp MAIN and sleep, and nothing having happened in any of the 
interrupt routines (I am certain because I had the interrupt routines 
set up to set a flag in a register, and none of the flags were set).

I am totally frustrated and discouraged at this point.   I realize that 
it is something *I* am doing wrong, but for the life of me, I am damned 
if I can determine what or where.  As I said earlier, I set up a very 
simple interrupt ina standalone program, and it worked fine.  the 
details of this one differ, of course, but the form is the same, and it 
does not work, at least net in simulation.

I am planning to obtain some physical processors in about 2 weeks,and 
will be able to check things on a real processor, though I am not very 
hopeful that the problem, will disappear, frankly.
