This implements a basic pure-Pyton PID controller (http://en.wikipedia.org/wiki/PID_controller).
Run:
pip install pid_controller
from pid_controller.pid import PID
pid = PID(p=0.1, i=0.004, d=3.0)
output = pid(feedback=get_feedback())
Run unittests:
export TESTNAME=; tox
To run a specific unittest:
export TESTNAME=.test_robot_steering; tox
To run tests for a specific environment (e.g. Python 2.7 with Django 1.4):
export TESTNAME=; tox -e py27
