# - Generate firmware and libraries for Arduino Devices

# TARGET_NAME - Name of target
# Creates a Arduino firmware target.

# The following suffixes are availabe:
# _SRCS # Sources
# _HDRS # Headers
# _SKETCHES # Arduino sketch files
# _LIBS # Libraries to linked in
# _BOARD # Board name (such as uno, mega2560, ...)
# _PORT # Serial port, for upload and serial targets [OPTIONAL]
# _AFLAGS # Override global Avrdude flags for target
# _SERIAL # Serial command for serial target [OPTIONAL]
