# Installing the STM32L4 gcc development chain on Mac OS X
#   (may be incomplete...  tested on 10.11.3)
################################################################################

# If you already have XCode installed you may skip this step.
# Install the needed tools for compiling local C programs. Select "Install" when prompted

  xcode-select --install

# Install homebrew, a package manager for OS X, which will be used to install the ARM cross-compiler, autoconf, automake, libusb, etc...
# Follow the installation instructions as prompted

  ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# Now get the required cross-compiler, library, and debugger for the arm processors

  brew tap PX4/homebrew-px4
  brew update
  brew install libtool stlink gcc-arm-none-eabi-49 wget

# Now install the libraries needed for ECE 486.  This download includes portions
# of the STM32cubeL4 software distributed by STM.
# ECE 486 routines are also provided to configure the 
# processors for real-time "double-buffering" applications.  
# The STM32L476G-Discovery board is supported.
#
# You'll need to download, compile, and install the libraries.  By default, the
# "make install" step will install the libraries in /usr/local/stmdev/
