Hi Eduardo,

There are some tools around that will let you draw state diagrams and 
generate code from them. Most of these are not optimised for small MCUs. 
They generate C or C++ code which you then need to compile into an 
executable. There is a version of ZMech that will generate optimised PIC 
(14 bit core) assembler. It supports direct interactive debugging of the 
generated state machine executable (you can toggle a virtual input and 
watch the path the state machine takes on the diagram, see a change in a 
virtual output and trace the code execution via the built-in simulator - 
all at the same time).

You can see a bit more about ZMech here:

and a bit more interesting PIC related stuff here:
