You can also find the documentation and some examples installed at:
/usr/share/doc/python3-pifacecad/
Make sure you are using the latest version of Raspbian:
$ sudo apt-get update
$ sudo apt-get upgrade
Install pifacecad (for Python 3 and 2) with the following command:
$ sudo apt-get install python{,3}-pifacecad
Test by running the sysinfo.py program:
$ python3 /usr/share/doc/python3-pifacecad/examples/sysinfo.py
You will need to configure the IR receiver.
The piface packages are currently not in the main repositories. You can, however, simply build them from their sources:
- Enable the spi-interface:
$ sudo raspi-config
Interfacing Options -> SPI -> Yes
$ sudo aptitude install liblircclient-dev cython gcc python{,3}-setuptools python{,3}-dev
$ git clone https://github.com/tompreston/python-lirc.git
$ cd python-lirc/
$ make py3 && sudo python3 setup.py install
$ make py2 && sudo python setup.py install
$ git clone https://github.com/piface/pifacecommon.git
$ cd pifacecommon/
$ sudo python setup.py install
$ sudo python3 setup.py install
$ git clone https://github.com/piface/pifacecad.git
$ cd pifacecad/
$ sudo python setup.py install
$ sudo python3 setup.py install
- run the hello world demo:
>>> import pifacecad
>>> cad = pifacecad.PiFaceCAD() # create PiFace Control and Display object
>>> cad.lcd.backlight_on() # turns the backlight on
>>> cad.lcd.write("Hello, world!") # writes hello world on to the LCD
- Cleanup:
$ sudo rm -rf pifacecad/ pifacecommon/ python-lirc/
