# -----------------------------------------------------------------------------
#             LUFA AVRDUDE Programmer Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
#   Provides a set of targets to re-program a device using the open source
#   avr-dude utility.
# -----------------------------------------------------------------------------
# TARGETS:
#
#    avrdude                   - Program target FLASH with application using
#                                avrdude
#    avrdude-ee                - Program target EEPROM with application data
#                                using avrdude
#
# MANDATORY PARAMETERS:
#
#    MCU                       - Microcontroller device model name
#    TARGET                    - Application name
#
# OPTIONAL PARAMETERS:
#
#    AVRDUDE_PROGRAMMER        - Name of programming hardware to use
#    AVRDUDE_PORT              - Name of communication port to use
#    AVRDUDE_FLAGS             - Flags to pass to avr-dude
#
