## Makefile-stm32duino-stm32f407ve-black-marlin
# version 0 (alpha)
#
# This make file for stm32duino core and Marlin 2.0 is possibly *dangerous*
# i.e. it compiles the sources (in src, Marlin, Arduino_Core_STM32, variants and CMSIS_5) directory
# and overwrite all the stuff in $(out_dir)
# $(out_dir) is the binary directory where the object files are dumped there
#
# make clean *deletes* the *$(out_dir)* (coded here as build )
#
# this is a relative path makefile
# the directory structure needs to be
# Root (project directory)
#   +-- src (your sources e.g. the sketch
#   |        the files has to be cpp, c or h, no ino)
#   |
#   +-- Arduino_Core_STM32 (from https://github.com/stm32duino/Arduino_Core_STM32)
#   |
#   +-- CMSIS_5 (from https://github.com/ARM-software/CMSIS_5)
#   |
#   +-- Marlin (from https://github.com/MarlinFirmware/Marlin)
#   |
#   +-- variants (see below)
#   |
#   +-- Makefile (this makefile)
#
# this makefile can't handle the brackets/paranthesis naming convention used for the variants
# hence you need to create a local variant folder and copy all the files in
#   Arduino_Core_STM32/variants/STM32F4xx/F407V(E-G)T_F417V(E-G)T/
# to
#   variants/F407VX/
#
# Marlin is from the github repository. v 2.0.x and above is needed to build Marlin with stm32duino
#   https://github.com/MarlinFirmware/Marlin
#
# the make needs to be run from the root of this file structure
# the make is relative path from this Root
# generated object files and binaries (elf, bin) are placed into the
# $(out_dir) - bin
#
# make clean  - *deletes* $(out_dir)
#
# make all  - starts the build
