# 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.
