Point taken, I'll amend. My project resides outside the amforth hierarchy, hence, I did not notice the hit. > For the other stuff "appl_own.py" I've not opinion yet.

It needs two configurable constants as both the polynomial chosen and the reading order are application specific (in fact MSB first is considered the reverse order). ( $D5 constant CRC8PLY -1 constant CRC8MSB ) I said, how nice it would be if amforth-shell would do it for me just like it does with Atmel's register/bit defs. By the way, I surround the above constants with () which amforth-shell.py respects but amforth itself does not. That's just perfect!
