OK, I changed that and fixed a lot of little bugs in my (unfinished)
example PIC code.

What do I need to hook in my port in order to call a function when
the state of a node (the keyboard scan line) changes, including
changes due to PIC TRIS bit changes?  My current attempt was to use
Keypad_Scan_Port:assert_event() to call my keypad processing, and
I thought that would be called by the setbit() function.  But it
doesn't seem to get called when the PIC changes its TRIS state.

Probably I still completely misunderstand how the whole node and
stimulus concept works.  Sorry about all the newbie questions.

Thanks!
