Welcome to the DCC-EX PowerShell installer for EX-CommandStation ($installerVersion)
Current installer options:
- EX-CommandStation will be built in $commandStationDirectory
- Arduino CLI will downloaded and extracted to $arduinoCLIDirectory
Before continuing, please ensure:
- Your computer is connected to the internet
- The device you wish to install EX-CommandStation on is connected to a USB port
This installer will obtain the Arduino CLI (if not already present), and then download and install your chosen version of EX-CommandStation
