# This file serves as documentation for config parameters. One may

|
# A note on pin names: pins may be configured with a hardware name
|
|
# (such as "PA4") or with an Arduino alias name (such as "ar29" or
|
|
# "analog3"). In order to use Arduino names, the pin_map variable in
|
|
# the mcu section must be present and have a value of "arduino".
|
|
# Pin names may be preceded by an '!' to indicate that a reverse
|
|
# polarity should be used (eg, trigger on low instead of high). Input
|
|
# pins may be preceded by a '^' to indicate that a hardware pull-up
|
|
# resistor should be enabled for the pin.

# sure the stepper motor driver is reset every time the mcu is
