Install Issue

[deobrien1962]

Having a problem with the installation of piface on a Pi 3

Went through all the steps and get the following form the console pi@raspberrypi:~ $ sudo apt-get install python{,3}-pifacedigitalio Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package python-pifacedigitalio E: Unable to locate package python3-pifacedigitalio

Tried cloning and I get the same result.

Same here.

I use the latest Raspbian (stretch) installation. I noticed on another RPi (with jessie) that the packets could be installed successfully.

[Admiraldr]

Seems that the packages are not part of Raspbian (stretch). As a workaround I installed an older Raspbian (jessie). There I was able to install the packages.

Would be really great if the piface packages are added to Stretch as well.

[deobrien1962]

Agreed... It would save all a great deal of time.

[netkruzer]

Agreed. Just installed a fresh install of Raspbian Stretch and sudo apt-get will not install the piface modules.

The same issue here...

I worked around it by using pip: sudo pip3 install pifacedigitalio sudo pip install pifacedigitalio

note: don't forget pifacecommon using the same method!

I had the same issue and it appears that the SPI bus speed increased from 100KHZ to 125KHZ on stretch. After some searching i have found a alternative solution which works for piface2. it is a pure python script and it works on raspberry stretch, is faster and uses the same syntax, so minimal programming changes:

I had the same issue on Raspbian GNU/Linux 9 (stretch). Nevertheless, the workaround from @jakorten worked for me.

For Python: sudo pip install pifacecommon sudo pip install pifacedigitalio

For Python3: sudo pip3 install pifacecommon sudo pip3 install pifacedigitalio

Please note, you need to make sure you have PIP installed first. If not, the following command will install PIP for both Python and Python3.

sudo apt-get install python{,3}-pip

Hello, I'm struggling to get my Raspberry Pi with PiFace Digital 2 working. I have the same issue as the OP but following all the advice in this thread hasn't helped. I would like to install the emulator to test some buttons a friend has set up on a breadboard connected to the PiFace.

I have run

sudo pip install pifacecommon
sudo pip install pifacedigitalio
For Python3:
sudo pip3 install pifacecommon
sudo pip3 install pifacedigitalio

and

https://github.com/bulletmark/pifaceio.git

Installed all the libraries successfully. What is the next step please?

Raspberry Pi 3 Model Model B V1.2 Raspbian GNU/Linux 10 (Buster)

@SiAust I am the author of the pifaceio package. Note it is completely independent to pifacedigitalio and is simply an alternative if you want to try something else. It is inappropriate to discuss it here so if you want help with that, please raise an issue there and I will help you out.

[SiAust]

@bulletmark Thank you. I will continue a conversation on your repo, I appreciate it.

The package isn't in debian, so apt won't work.

Use pip, which is the official way to install Python packages. https://pypi.org/project/pifacedigitalio/

@bulletmark pifaceio looks great.

There's also a devicetree overlay if you want to write a driver for that. Might be simpler than crafting your own SPI packets - just let the kernel do it. https://github.com/raspberrypi/linux/pull/3794

This approach worked for me. Also, you apparently need to visit sudo raspi-config and enable SPI, for example, in the Interfaces section and reboot.
