#Python Hardware Support ##prerequisites The rotary switch is an I2C device. It is accessed via python-smbus. The easiest way to enable spi support is via raspi-config->Advanced Options->I2C

apt-get install python-smbus

The display is a 128 x 32 x 1 graphic display utilizing the NewHaven Displays xxxxxx SPI device. The graphic display is accessed via python-spidev. The easiest way to enable spi support is via raspi-config->Advanced Options->SPI

apt-get install python-spidev

The display's backlight uses the raspberry pi's hardware PWM to control brightness level. The hardware is accessed via the WiringPi (which used the wiringpi C language code to access the hardware. Building it has other dependencies; listed below. A more thoughtful build process is described at: https://github.com/WiringPi/WiringPi-Python

apt-get install python-dev python-setuptools swig
# try building without python-pytest.  I don't think it's needed.
# apt-get install python-pytest
git clone --recursive https://github.com/WiringPi/WiringPi-Python.git
cd WiringPi-Python
git submodule update --init
cd WiringPi
./build
cd -
swig2.0 -python wiringpi.i

# LDFLAGS are needed for some versions or WiringPi-Python
LDFLAGS="-lcrypt -lrt" python setup.py install

optional

###ImageMagick The graphics used by the demo.py script were created using ImageMagick. Those images can be created anywhere so, for space or performance reasons, you may not to install it on your raspberry pi.

apt-get install imagemagick
