One of the things I do is to transmit using the USART and via RS232 some
useful data to the PC, so I can see what's realy going on in there.
        Also, If you have some LCD or 7 segment disp. You can print the
data in those displays...

Subject: [PIC]: Debugging code in the chip


I am curious about how people debug their code once they have burned it
into the chip and it does not work correctly.  Would appreciate any
feedback I can get.

I'm not talking about the commercial guys, now, with their
zillion-dollar systems, but the poor hobbyists (like me) who have a
breadboard, a chip, a few components, and a simulator.

Simulators are wonderful, but at some point you have gone through the
code, and it all looks correct; you have run it through the simulator
and it works perfectly, you burn it into the chip, and BAM! it does not
work. :-(

So how do people debug it at that point?  (I have some ideas, but I am
sure there are a whole raft of things I have not thought of).

John
