Linux

To access the MPSSE mode on Linux we need to install libftdi and the Adafruit Python GPIO library. Carefully follow the steps

below to install these libraries.

Note that these steps are made for Ubuntu 12.04/14.04 and should work with any Debian-based distribution. If you're using a

different distribution you might need to check its package manager for the appropriate commands to install the mentioned

dependencies.

In a command terminal execute the following commands to install libftdi and its dependencies.

NOTE: This assumes you're installing on a Debian/Ubuntu/Raspbian-based system and will use Python 2.7. If you're using a

different version of Python or your distribution installs Python in a different location you might need to change the paths of the -

DPYTHON_xxxx environment variables in the cmake command.

sudo apt-get update

sudo apt-get install build-essential libusb-1.0-0-dev swig cmake python-dev libconfuse-dev libboost-all-dev

wget http://www.intra2net.com/en/developer/libftdi/download/libftdi1-1.2.tar.bz2

tar xvf libftdi1-1.2.tar.bz2

cd libftdi1-1.2

mkdir build

cd build

cmake -DCMAKE_INSTALL_PREFIX="/usr/" -DPYTHON_INCLUDE_DIR="/usr/include/python2.7" -DPYTHON_LIBRARIES="/usr/lib/python2.7/" ../

make

sudo make install

The commands above should complete without any errors. If you do see errors, make sure all the dependencies were installed

with the apt-get install command.

Next download the Adafruit Python GPIO library by clicking the button below:

Adafruit Python GPIO Library

http://adafru.it/eaL

Unzip the archive and navigate to the folder inside a terminal. Then run the following command to install the library:

sudo python setup.py install

You should see the Python library successfully install without any errors.

To test the libraries are installed run the following command in a terminal to open the Python interpretor:

python

At the Python interpretor >>> prompt type the following commands to test loading the libraries:

import Adafruit_GPIO

import ftdi1

You should see no response from the Python interpretor after entering each line. If you do see an error that a module cannot be

loaded, go back to the libftdi installation steps above and carefully check they completed successfully.

If there are no errors, congratulations you've successfully installed libftdi and the Adafruit Python GPIO library! Move on to the

next section to learn how to access the MPSSE mode GPIO, SPI, I2C, etc.

To quit the Python interpretor enter the following:

quit()
