Cosa Board pin symbol definitions mapping to difference board/processor types. Cosa does not use pin numbers as Arduino/Wiring. Instead strong data type is used (enum types) for the specific pin classes; InputPin, OutputPin, AnalogPin, etc. The actual board implementation class is selected by the build.
