I've found that, in general, the amount of C code you can 'fit' into
the miniboard is small enough that just staring at the code is enough
to find most if not all bugs. (If you get three pages of code into the
thing you're lucky) On the other hand it is useful to do debugging and
sometimes printing out to the serial port isn't an option (like the
miniboard is riding on its power supply which is headed for a cliff :-))

In such situations it is fairly easy to put LEDs on unused bits in port C
and turn them on at appropriate times. By soldering a resistor on one of
the low power ones you can just "plug it in" between the output ping and
the 5V line. Then drive the output pin low to turn on the LED.
