The Arduino only works, if LinuxCNC is running and an USB Connection is established.
To give optical Feedback of the State of the connection a Status LED setting is provided.
This can be either an LED connected to an Output Pin or you can select one LED in your Digital LED Chain.

# Serial communication over USB
The Send and receive Protocol is :
To begin Transmitting Ready is send out and expects to receive E: to establish connection. Afterwards Data is exchanged.
Data is only send everythime it changes once.
- Inputs & Toggle Inputs = 'I' -write only -Pin State: 0,1
- Outputs = 'O' -read only -Pin State: 0,1
- PWM Outputs = 'P' -read only -Pin State: 0-255
- Digital LED Outputs = 'D' -read only -Pin State: 0,1
- Analog Inputs = 'A' -write only -Pin State: 0-1024
- Latching Potentiometers = 'L' -write only -Pin State: 0-max Position
- Absolute Encoder input = 'K' -write only -Pin State: 0-32

Command 'E0:0' is used for connectivity checks and is send every 5 seconds as keep alive signal. If connection is lost the arduino begins flashing an LED to alarm the User.
