Part 1 - Introduction The PiFace Digital I/O card connects to your Pi's 26-way IDC header and sits over the Pi to provide a compact interface to digital input and output ports. PiFace provides: 8 digit input ports - presented on a nine-way terminal strip, these will detect open circuit or closed circuit with respect to a common ground connection. The first four inputs have momentary pushbuttons so that you can perform basic testing. 8 digital output ports - presented on a nine-way terminal strip and share a common +5V connection.
The first two outputs also drive separate SPDT relays that have three connections each: NO, NC, Common. Each output has its own LED to indicate an ON condition. Hover your mouse over the picture of the PiFace to see a description of each main component. The easiest way to install the PiFace software and associated system settings is to use PiFace's own disk image. There are several jumpers on the PiFace boards and these have the following purposes: Using C. Redirecting.

Fitting the board PiFace Digital sits neatly above the Raspberry Pi and connects using the expansion connector. Installing Software The fastest way to get started is to download a prepared operating system image and copy it to an SD card. Alternatively, you can install the necessary libraries to your own Raspbian image with the instructions below. Installing the software yourself in Raspbian PiFace Digital communicates to the Raspberry Pi using the SPI interface. Sudo reboot 1. 2. Thomasmacpherson/piface. PiFace documentation.
