Mike, Pete,
I've put a first full draft of the tutorial document for FF5 at
http://dropbox.eait.uq.edu.au/e4pjacob/flash-forth/ff5-tutorial-guide-2014-05-04.pdf
Comments most welcome.
Towards the end, I've tried out the bit manipulation words and, when
inlined, they do achieve full machine speed on the PIC18 and PIC24.
They're a little slower on the ATmega328, however, they do work nicely.
Along the way I fell over the way the AVR version of FF doesn't like tab
characters in leading whitespace (indentation). The PIC18 seems to be
insensitive to whether there is tab character or space characters for
that indentation. It took me a while to realize that the compiler was
upset by the tab character since the message was that it didn't know my
word (that had been defined and used earlier).
Cheers,
Peter J.
