# Compatiblity
This software works with LinuxCNC 2.8, 2.9 and 2.10. For 2.8 however you have to change #!/usr/bin/python3.9 in the first line of arduino.py to #!/usr/bin/python2.7.

In the Beginning the Arduino will Spam ```E0:0``` to the console. This is used to establish connection.
Just return ```E0:0``` to it. You can now communicate with the Arduino. Further info is in the Chapter [Serial Communication](#serial-communication-over-usb)

# Latching Potentiometers / Selector Switches
This is a special Feature for rotary Selector Switches. Instead of loosing one Pin per Selection you can turn your Switch in a Potentiometer by soldering 10K resistors between the Pins and connecting the Selector Pin to an Analog Input.
The Software will divide the Measured Value and create Hal Pins from it. This way you can have Selector Switches with many positions while only needing one Pin for it.

Joysticks use a similar implementation as Quadrature encoders and are implemented with the usecase as MPG in mind.
Connect your X and Y Pin of your Joystick to an Analog Pin of your choice.
