RE: raspberry pi with piface

Checkout you are using the full path the the file:

Instead of "sudo nano etc/modprode.d/raspi-blacklist.conf" try :

sudo nano /etc/modprode.d/raspi-blacklist.conf

The "/" at the start of the file's path is important because it means to start searching for that file from the root directory. Without it it means to start searching for that file from current directory.

I am sorry but I don't fully understand the other questions, but just as a pointer, every Python script you run in idle, can be run outside of idle.

To download pyface emulator the best way is to boot your raspberry, log into it by ssh or plug a keyboard and screen to it, and on a terminal use the commands:

sudo apt-get update sudo apt-get upgradesudo apt-get install python{,3}-pifacedigitalio

https://github.com/piface/pifacedigitalio

You don't need the emulator for the pifacedigitalio library to work, but you can easily install it with the same method but with those commands:

sudo apt-get update sudo apt-get upgrade

sudo apt-get install python3-pifacedigital-emulator

https://github.com/piface/pifacedigital-emulator

Usually for the buttons to make anything you need to write a program that reads the inputs from the buttons and makes something with this inputs.

As example from the reference Reference — PiFace Digital I/O 3.0.5 documentation :

def print_flag(event):

print(event.interrupt_flag)

listener = pifacedigitalio.InputEventListener()

listener.register(0, pifacedigitalio.IODIR_ON, print_flag)

listener.activate()

This program should print something to standard output each time you press a button.
