klipper/config/generic-cramps.cfg

# This file contains an example configuration for a Beaglebone PRU
# micro-controller attached to a CRAMPS board.

# THIS FILE HAS NOT BEEN TESTED - PROCEED WITH CAUTION!

# NOTE: Klipper does not alter the input/output state of the
# Beaglebone pins and it does not control their pull-up resistors.  In
# order to set the pin state one must use a "device tree overlay" or
# use the config-pin program.

# See docs/Config_Reference.md for a description of parameters.
