ST / Mbed OS HelloWorld_PLC01A1

An example of usage of the X-NUCLEO-PLC01A1 Programmable Logic Controller Expansion Board.

Dependencies:   X_NUCLEO_PLC01A1

PLC with the X-NUCLEO-PLC01A1 Expansion Board

This application provides a simple example of usage of the X-NUCLEO-PLC01A1 Programmable Logic Controller Expansion Board.
It shows how to use one PLC connected to the board, driving the status of each output channels according to the status of each input channels.
