# Makefile for compiling STM32F1xx devices, specially, STM32F103C8T6 or bluepill
# Copyright (C) 2020 Alexandre Amory <amamory@gmail.com>
#
###############################################################################
# RELEVANT VARIABLES:
#
# Main makefile that compiles all libs and all examples.
#
# In the TERMINAL, point the LEARNING_STM32 to the directory of the base project.
# For example:
#
#    $ export LEARNING_STM32=$HOME/learning-stm32
#
# Alternatively, you can also set this variable in the ~/.bashrc file.
#
#
# In the MAKE command, it is possible to define the other relevant variables:
#
#    V=1 : enables verbose mode
#    DEBUG=1: enables debug mode. Otherwise, the code is optimized for size
#
# Usage example:
#    $ make V=1 <=== enables verbose mode
#    $ make DEBUG=1 V=1 <=== enables both verbose and debug modes
