+# 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 a board name (such as ar29). In order to use a
+# board name, the pin_map variable in the mcu section must specify
+# which board definition to use. (See the klippy/pins.py file for the
+# available pin and board names.)
+# 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 prceded by an '^' to indicate that a hardware pull-up
+# resistor should be enabled for the pin.
