klipper-dgus/config/generic-replicape.cfg

# This file contains an example configuration for the Replicape rev B3
# board. To use this config, one must compile and install the
# micro-controller code for the "Beaglebone PRU", and then compile and
# install the micro-controller code a second time for a "Linux
# process".

# NOTE: Klipper does not alter the input/output state of the
# Beaglebone pins and it does not control their pull-up resistors.
# Typically the correct settings are automatically applied when the
# Beaglebone detects the Replicape board, but if changes are needed
# they must be specified in a "device tree overlay" or via the
# config-pin program.

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