klipper-dgus/config/printer-biqu-bx-2021.cfg

# This file contains common pin mappings for the BigTreeTech SKR SE BX.
# To use this config, the firmware should be compiled for the
# STM32H743 with a "128KiB bootloader". Additionally, GPIO pins PB5
# and PE5 need to be set at microcontroller startup.

######################################################################
# NOTE: In order enable the TFT70-BX display when the printer first
# starts, add PB5 and PE5 to the `GPIO pins to set at micro-controller
# startup` section when running "make menuconfig"
######################################################################

# The "make flash" command does not work on the SKR SE BX. Instead,
# after running "make", copy the generated "out/klipper.bin" file to a
# file named "firmware.bin" on an SD card and then restart the SKR SE BX
# with that SD card. After klipper has been flashed once to the board,
# you can update klipper by leaving a microSD inserted and running the
# scripts/flash-sd.sh script.

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