Hi Mike
I am working headless and github will not allow me to access packages over internet even though I setup an account with username and password. Still at first base. I tried the installation from the piface site and although it appeared to work I cannot find piface directory.
thanks
Bill

Hi again Bill,

I decided to go ahead and try running the Piface Digital 2 on a Pi4B. I used the manufacturer’s instructions and they worked perfectly so they must have corrected the problems that blighted the original release. I suggest you follow their instructions, here’s the link: PiFace Digital 2 installation

Regards,

Mike

Hi Bill, What model Pi are you using? I’ve got a PiFace2 here so will set one up to make sure it works ok and let you know the details.

Regards,

Mike – G4WNC

I will try your solution as from above it appears to be very successful. As I am a real beginner I hope you will excuse me if I appear to ask a couple of silly questions. Firstly are the updates now in place and what would I need to do to installpifaced2 package and secondaly at what point do I fit the pifaced2 board in the installation.thirdly does the emulator work
Thanks
Bill

Thank you for this post. Very useful. I have a piface digital 2.
I have purchased a Pi 4 and downloaded the latest OSI have followed all your instructions and installed python 3.7.3 as well
When I use Thorny it shows python 3.7.3 as the version I am using.
I am getting an error on line 2 which is the p.init()
The error given is
Traceback (most recent call last):
File “/home/pi/pifacetest.py”, line 2, in
p.init() # initialise the Piface board
File “/usr/local/lib/python3.7/dist-packages/pifacedigitalio/core.py”, line 166, in init
raise failed_boards[0]
File “/usr/local/lib/python3.7/dist-packages/pifacedigitalio/core.py”, line 162, in init

self.init_board()
File “/usr/local/lib/python3.7/dist-packages/pifacedigitalio/core.py”, line 107, in init_board
h=self.hardware_addr, b=self.bus, c=self.chip_select))
pifacedigitalio.core.NoPiFaceDigitalDetectedError: No PiFace Digital board detected (hardware_addr=0, bus=0, chip_select=0).

I am guessing this is something to do with the SPI speed. (SPI is enabled).
Might I ask you if you now what might be causing this and how to correct it please? I think it might be an SPI speed mismatch between the pi and the piface.
Thanks in advance

With an (old) Piface and its old partner Raspberry Pi B+ (have a 4B too) everywhere have raspbian buster working fine. Should like to know if my piface is still alive so I tried for now with your directions THANK YOU VERY MUCH for them and for this page. In brief: wrote your instructions in a file and running got a “No module named pifacedigitalio”. A new run of sudo pip3 install pifacedigitalio yields a “Requirement already satisfied: pifacedigitalio in /usr/local/lib/python3.7/dist-packages (3.0.5) so I assume either a link or a different invocation for the library is advisable, though I don’t know which it should be. I tried python first though I use C and other languages ’cause I need a quick way to figure out if my piface can run or it’s already dead.
Thanks for your help.

Thanks Loulli,

Glad to hear its working for you. Everyone needs to switch to python 3 and it’s a simple change.

Works fine with my PiFace Digital 1, Raspberry Pi 3, Raspberry Pi OS (kernel: v4.19). I just had to replace “python” by “python3.7” as used by Thonny Python IDE.
