Example: Controlling the PiFace Module Connected via SPI (1)

Product: CODESYS Control for Raspberry Pi

The PiFaceIoDrv.project project contains an application which controls a Raspberry PiFace Digital I/O hardware with 8 digital inputs and outputs. An I/O driver is used instead of an implicit FB instance. The I/O driver implements the exchange of inputs and outputs in the usual way for controllers by means of the process image.
