If you are talking about this library:

http://pypi.python.org/pypi/pyftdi

have you tried reading the documentation, such as it is? I've had a quick 
look, and it appears to be extremely light on documentation, but I didn't dig 
too deeply, maybe you will have better luck. The GitHub page claims to have 
some examples, but I couldn't get it to work in my browser.

You can also try this at the Python interactive interpreter:

import pyftdi
help(pyftdi)


and see if the library has any useful embedded documentation. It may not.


Do you know how to start the interactive interpreter? You need to open a 
terminal window, then at the prompt, you need to launch Python. Under Linux, I 
just type

python

and hit the ENTER key. If you are using Windows, it may be more complicated.
