Documentation

Please note that documentation is mostly lacking at the moment. Use the source, luke!

Controlling the pins is as easy as echo num state >/dev/ppin, where num is 0 to 7 and state is one of on or off. For example echo 3 on >/dev/ppin switches the 3rd pin on.

You can read the status of the pins with cat /dev/ppin.
