# unstrobed
# Specifies a single pin to read and the corresponding HID code.
# This is intended for a single switch which can be wired with the other side of the switch permanently connected to either ground or +5V. If the other side of the switch is at +5V, a pull-down resistor must be added between the pin and ground.
# Example:
# unstrobed -PF1 LSHIFT
