Inexpensive 8-bit microcontrollers include many dozens of i/o pins backed up by interesting hardware including USB interfaces.
We show how a simple interpreter, called Txtzyme, running on an 8-bit micro-controller, can support generalized hardware interaction and expose that to a regular computer over the flow-controlled USB bus. The result is to make your hardware feel "command line friendly" while concentrating your system development efforts into a more powerful and interactive development environment: the shell.
Sources for Txtzyme and all the "demo projects":https://github.com/WardCunningham/Txtzyme are on GitHub and have been blogged at DorkbotPDX. See our "original announcement":http://dorkbotpdx.org/blog/wardcunningham/shell_programming_with_txtzyme there and a "more recent post":http://dorkbotpdx.org/blog/wardcunningham/txtzyme_accepted_for_open_source_bridge describing additional preparations for this talk.
