You may want to run pypilot as a service, see the scripts/debian directory


install:

sudo pip install PyOpenGL
sudo apt-get install python-numpy python-scipy


Clone the data repository and copy data
git clone https://github.com/pypilot/pypilot_data
cp -rv pypilot_data/* pypilot

most of the scripts can be run individually as standalone
or test programs, some function as clients, other as servers


servers (only one executes at a time)

pypilot/simple_autopilot.py -- classic PID based autopilot implementation
pypilot/basic_autopilot.py -- basic PID based autopilot with additional gains and filters

These server scripts can be run as tests:
* execute this script directly

signalk/server.py -- implements poll based server allowing external manipulation,
                     * basic demo server with clock
signalk/pipeserver.py -- implements tcp sockets in a separate unix process
                         relieving the main process from json parsing, and transmission.
                         * basic demo server
pypilot/boatimu.py -- specialized imu specific to boat motions
                      includes automatic 2d/3d calibration and alignment of magnetic sensors
                      * useful for testing the imu (gyros) or even just reading gyros
                      
pypilot/nmea.py -- signalk <-> nmea0183 translator
                   reads nmea0183 from serial ports or from tcp connections, and multiplexes
                   the output to both nmea0183.
                   * convert and multiplex nmea0183 data

pypilot/servo.py -- controls servo via RC pwm signal, and gpio feedback for fault
                    * use to test or verify a working servo is detected,
                      can be used to control or calibrate the servo



clients (run as many of these):

ui/autopilot_control.py -- simple interface to command autopilot
ui/autopilot_calibration.py -- interactive gui for all autopilot calibrations
ui/kivy -- work in progress kivy control app

signalk/client.py -- console client
signalk/client_wx.py -- graphical user version (wx widgets)
signalk/scope.py -- glut plot client -- useful for sensors and control
signalk/scope_wx.py -- plot client with wx widgets (for checked listbox)

lcd/client.py -- autopilot control interface using GPIO pins.

webapp/webapp.py -- python flask application that runs a webserver providing remote autopilot control through a browser
