# HARDWARE_PLATFORM_PATH/
# |-- bootloaders/
# |-- cores/
# |-- variants/
# |-- boards.txt
# `-- programmers.txt
#
# The board.txt describes the target boards and bootloaders. While
# programmers.txt the programmer defintions.
#
# A good example of a Hardware Platform is in the Arduino SDK:
#
# ${ARDUINO_SDK_PATH}/hardware/arduino/
#
#=============================================================================#
# Configuration Options
#=============================================================================#
#
# ARDUINO_SDK_PATH - Arduino SDK Path
# ARDUINO_AVRDUDE_PROGRAM - Full path to avrdude programmer
# ARDUINO_AVRDUDE_CONFIG_PATH - Full path to avrdude configuration file
#
# ARDUINO_C_FLAGS - C compiler flags
# ARDUINO_CXX_FLAGS - C++ compiler flags
# ARDUINO_LINKER_FLAGS - Linker flags
#
# ARDUINO_DEFAULT_BOARD - Default Arduino Board ID when not specified.
# ARDUINO_DEFAULT_PORT - Default Arduino port when not specified.
# ARDUINO_DEFAULT_SERIAL - Default Arduino Serial command when not specified.
# ARDUINO_DEFAULT_PROGRAMMER - Default Arduino Programmer ID when not specified.
#
#
# ARDUINO_FOUND - Set to True when the Arduino SDK is detected and configured.
# ARDUINO_SDK_VERSION - Set to the version of the detected Arduino SDK (ex: 1.0)
