How do I find out what IRQ triggered a debug breakpoint at NonHandledInterrupt?

I cannot get interrupts to work and I found that NonHandledInterrupt is getting called. How do I find out what IRQ triggered a debug breakpoint at NonHandledInterrupt? I've stared at my code for hours and all it does is stare back.

I figured out one way to do it. I made a number of routines: NonHandledInterrupt1, NonHandledInterrupt2, NonHandledInterrupt3, etc. for sections of interrupt vectors. I was able to identify the guilty interrupt. It would be nice if there was an easier way but there probably isn't.

NonHandledInterrupt  means that you enabled some interrupt (timer, uart...) but do not have the corresponding code to handle that interrupt. Just disable one interrupt in your code at a time and you'll see when the NonHandledInterrupts disappear.
