Re: Nesting Interrupts - is it possible?

I actually have a good reason for doing this, but I suspect the chip can't handle re-entrant code.

Thanks In Advance for your wisdom.
Yes, with low-priority interrupts it can. If you don't know what a low priority interrupt is, then jsut take my word and know it will work. Just don't try too many interrupts inside interrupts, as these are added to the stack, which will eventually overflow if you do.
