# Duet2 Maestro analog scaling by vref and vssa readings. Defining an
# adc_scaled section enables virtual adc pins (such as "my_name:PB0")
# that are automatically adjusted by the board's vref and vssa
# monitoring pins. Be sure to define this config section above any
# config sections that use one these virtual pins.
