Yes and No.
Yes, its better that the microcontroller be another PIC. This is to make
the I/O lines more or less the same in characteristics. I'm not familiar
yet with PIC microcontrollers because I still haven't obtain any data book
or whatsoever. But the thing is, if the I/O lines have, say, internal
pull-ups, etc., you don't have to do external circuit for it. Its better
to keep things simple--as always.
No, it doesn't have to be another PIC (but of course, Parallax would
suggest otherwise!). For example, a 68HC11 can do.
I think the code simulation can be inside the microcontroller (instead of
the PC). The microcontroller code can then contain a Host Debugger
INterface to the Host. This would mean a faster code emulation.
But then, we have to write a more difficult emulation core on the
microcontroller. Better to keep it inside the PC. Keep things simple.
