I have an old PiFace board running on my old Raspberry Pi. Everything used to work perfectly but I decided to format the SD card and update to the latest Raspbian and now I can't get the PiFace to work again. I followed the instructions on http://www.piface.org.uk/guides/Install ... _Software/ but when I run the test program I get the error message that says: no piface digital board detected.
I googled the error and tried a couple of things that were suggested but I can't get it working. Can someone perhaps help?
