Try http://web.archive.org/web/20180222130452/http://pi.cs.man.ac.uk/download/

Hello Christopher,

Sorry but I tried multiple O.S. but always problems like with "Jessie" following this "PiFace Digital 2 - setup and use" procedure on "https://www.element14.com/community/message/133136/l/piface-digital-2-setup-and-use#133136" but the mainly problem is that some links are invalid :

Thank you for your answer but this does not allow me to move forward !

Please could you send to me these information ?

- The recommended O.S. , distrib and version like "2017-07-05-raspbian-jessie" , "2020-02-13-raspbian-buster" , "2018-04-18-raspbian-stretch" , and so on.

- Which procedure must I use ? Like "http://piface.github.io/pifacedigitalio/installation.html" but I found some problems with "pifacedigitalio" unreachable.

- Which type of µSD Card ? Like "SAMSUNG EVO 32 GB HC1 A1" , "SanDisk Ultra 64 GB XC1" , "SanDisk Extreme PRO 64 GB XC1 V30 A2" , and so on.

This link works well : "http://web.archive.org/web/20180222130452/http://pi.cs.man.ac.uk/download/"

But the result of its links are the folowing :

Thanks in advance for your answers and have a nice day ,

Antonio.

davinha, before I go down a rabbit hole of finding these files from the internet archives, I'll ask internally to see what the support status of this hardware is.

Thank you very much Christopher , for your help !

Hi Christopher ,

Please have you some more information ?

Here you have the information about my system software :

     pi@raspberrypi:~ $ lsb_release -a

     No LSB modules are available.

     Distributor ID: Raspbian

     Description: Raspbian GNU/Linux 10 (buster)

     Release: 10

     Codename: buster

I use Domoticz :

     Version: 2020.1

     Build Hash: 63fa969e4

     Compile Date: 2020-03-22 15:16:16

     dzVents Version: 3.0.1

     Python Version: 3.7.3 (default, Dec 20 2019, 18:57:59) [GCC 8.3.0]

And I want to use also PiFace Digital 2 but I can't install this :

     sudo apt-get install python3-pifacedigitalio

I have always the following message :

     pi@raspberrypi:~ $ sudo apt-get install python3-pifacedigitalio

     Lecture des listes de paquets... Fait

     Construction de l'arbre des dépendances      

     Lecture des informations d'état... Fait

     E: Impossible de trouver le paquet python3-pifacedigitalio

How can I do to use "python3-pifacedigitalio" ?

May be by adding some download source reference ?!

Thank you in advance for your help !

Antonio.

Try

pip3 install pifacedigitalio

Hi Christopher ,

Thank you for this information , it was installed successfully , but I still can't use PiFace Digital 2 yet !

As you could see "Successfully installed pifacedigitalio-3.0.5" but when I try to use it I have always this message " ModuleNotFoundError: No module named 'pifacecommon' " , pleas see below :

=================================================

By the way , I tried to install also " pip3 install python3-pifacedigital-emulator " and

" pip3 install python3-pifacedigital-scratch-handler " but  I'm faced to these errors :

Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/python3-pifacedigital-emulator/

Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/python3-pifacedigital-scratch-handler/

So , thank you in advance for your help and if you can send to me these information and I hope that I'll have a chance to see working this PiFace Digital 2 module what I baught it in November 2019 !

Antonio.

pip3 install pifacecommon

Here are the other modules: https://pypi.org/search/?q=piface

Hi Christopher ,

Thank you very much for this information , it was installed successfully with this command " pip3 install pifacecommon " !

Now I can use "python software " to read or write the all ports !

Very good !

Please , just one last thing , is it possible to have also the necessary to install and use the " Piface Digital-emulator " as explained in the pages 11-12 of " 1881551.pdf " , found on http://mchobby.be/data-files/RASP-PIFACE-DIGITAL2/Operating-Instruction.pdf ?

  I tried to install also " pip3 install python3-pifacedigital-emulator " and

" pip3 install python3-pifacedigital-scratch-handler " but  I'm faced to these errors :

Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/python3-pifacedigital-emulator/

Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/python3-pifacedigital-scratch-handler/

Many thanks for you answer and if you have the right information for the " python3-pifacedigital-emulator  " i'll appreciate !

Thank you very much again ,

Antonio.

As you will have seen at https://pypi.org/search/?q=piface  the emulator and scratch handler are not pip packages.

There's nothing I can do about this.

You can try building/setting it up from the github repository https://github.com/piface/pifacedigital-emulator / https://github.com/piface/pifacedigital-scratch-handler

Hi Christopher ,

As you could see , I tried following the README.md from " https://github.com/piface/pifacedigital-emulator "

Instructions for pifacedigital-emulator :

     An emulator for the PiFace Digital I/O board.

     Install :

     Make sure you are using the lastest version of Raspbian :

     $ sudo apt-get update

     $ sudo apt-get upgrade

     Install pifacedigital-emulator (for Python 3) with the following command :

     $ sudo apt-get install python3-pifacedigital-emulator

Result :

pi@raspberrypi:~ $ sudo apt-get install python3-pifacedigital-emulator

Lecture des listes de paquets... Fait

Construction de l'arbre des dépendances      

Lecture des informations d'état... Fait

E: Impossible de trouver le paquet python3-pifacedigital-emulator

pi@raspberrypi:~ $

The result is the same as for " sudo apt-get install python3-pifacedigitalio " , initial problem = " E: Unable to find the python3-pifacedigital-emulator package " !

So , have you another way or maybe changing or add some information in " sudo nano /etc/apt/sources.list " ?

Thank you very much in advance for your informations ,

Antonio.

davinha , you have to ignore the readme and merely download the github repo. the github repo has all of the files.

You'll notice this repository has 'setup.py' which you should probably investigate, similar for the other github link.

https://github.com/piface/pifacedigital-emulator/issues/9#issuecomment-592191287

It's unfortunately evident that using 'apt' or 'apt-get' to install the packages is never going to work until yourself or someone else maintains and sets up a new package for Raspbian for the files contained in the github repository.
