The program is started by calling the GUI.py which will start the daemon thread.
$ python GUI.py-
Daemon.py: Runs in the background and takes data from the arduino and GUI to update users' balances. This listens for input from Serial from the arduino and input from the GUI from the user.
-
GUI.py: Uses wxPython to create a GUI for the touch screen. This is updated by the daemon to display the user's name and balance.
-
connector.py: Deals with all the IO calls. Calls out to the drink API to get user information and update user's credits. This also deals with all the logging.
- wxPython
- configParser
- pyserial
- requests
- python-ldap
On rasbian, wxPython is provided by python-wxgtk3.0 and the others are avaliable as-is on pip.
These commands will install dependencies and other needed tools:
$ sudo apt-get install vim ntpdate arduino matchbox-keyboard
$ sudo apt-get install python-dev libsasl2-dev python-dev libldap2-dev libssl-dev python-wxgtk3.0 libcanberra-gtk-module
$ sudo apt-get install --no-install-recommends packagekit-gtk3-module #gnome and all of its tools are reccomened
$ sudo svstemctl disable ntpd && sudo systemctl stop ntpd
$ sudo ntpdate
$ sudo pip install --upgrade python-ldap configParser pyserial requests####Build xinput_calibrator
Install xinput_calibrator dependencies and build tools
$ sudo apt-get install dh-autoreconf libx11-dev libxi-dev x11proto-input-devClone xinput_calibrator and build. Only use 3 cores because it doesn't take that long and the pi is slow.
$ git clone https://github.com/tias/xinput_calibrator.git
$ cd xinput_calibrator
$ ./autoconf.sh
$ make -j3
$ sudo make install
$ DISPLAY=:0.0 xinput_calibrator####Making the calibration permenant
Copy the "Section ... End Section" from the output and put it in a file at /etc/X11/xorg.conf.d/99-calibration.conf, delete whatever is there already, and restart.
####Running the GUI on Startup
####Test the GUI once
First, make sure that the Arduino is mounted at the correct devive name, ACM0.
$ arduino$ cd AutoDrinkAdmin $ ./launcher
