====== Raspberry Pi notes ======

===== Setting up GPIO =====

From memory, the ruby libraries are junkily slow.  Python might work better.

You may need to

  apt install rpi.gpio

although this seems to be installed by default; this command just adds python packages.

Then a [[http://wiringpi.com/the-gpio-utility/|command line utility]] is needed to wrap these calls, even from zsh:

  apt install wiringpi

Then ''gpio'' should be available from the command line.
