# Makefile based on STM32Cube auto-generated makefile
|
|
#
|
|
# TODO:
|
|
# - clean up, maybe optimize builds more
|
|
# - add windows support
|
|
# - add *proper* retargeting (this is mostly restructuring some files and adding make variables)
|
|
#
|
|
# Mediocre stuff about how I'm doing this:
|
|
# - First build times are loooooong. make -j4 will help, but we're still compiling lots we do't need.
|
|
# This is mostly because I don't want people to have to specifiy which source files they need.

# Common directories
|
|
#
|
|
# These variables need to be defined in your makefile:
|
|
# TARGET - the name of your project
|
|
# COMMON_DIR - the common/ folder, where everything not for a specific project is held
|
|
# PROJ_DIR - Location of the current project
|
|
# MCU_SERIES - f0, f3, etc... the series for STM32 you are using
|
|
# MCU_PARTNO - Full partno you are using, in the HAL style, e.g. STM32F303xC
|
|
#
|
|
# SOURCE_DIRS - project specific sources, can be empty
|
|
# LDSCRIPT - The locaton of your linker script.
|
|
#
|
|
#
|
|
# CPU, see example makefile
|
|
# FPU, see example makefile
