Reads signals from the test bench (PLC) every time the trigger pin is activated by the same PCL and sends them to the remote server. It is divided in 7 files just for the sake of readability:

• Initialize the ethernet module.

• Read MAC address from the RTC.

• Check if the device is online.

• Simple implementation of a finite state machine.

• Transition between offline, connecting, connected and active states:

• offline. Device is not connected to the network.

• disconnected. Remote server is not responding UDP messages.

• connected. Device is waiting for the PLC's trigger.

• active. Device send TCP message to remote server and awaits response.

• Pin setup.

• Monitor trigger pin used by PLC.

• Read inputs from PLC.

• Write result to output pins.

• Initialize LCD screen.

• Centralize messages displayed.

• Control brightness changes.

• Send TCP message to remote server.

• Awaits remote server response.

• Initialize UDP client.

• "Ping" remote server.
