# LUFA ATPROGRAM Programmer Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
# Provides a set of targets to re-program a device using the Atmel atprogram
# utility in AVR Studio 5.x and Atmel Studio 6.0 onwards.
# -----------------------------------------------------------------------------
# TARGETS:
#
# atprogram - Program target FLASH with application using
# atprogram
# atprogram-ee - Program target EEPROM with application data
# using atprogram
#
# MANDATORY PARAMETERS:
#
# MCU - Microcontroller device model name
# TARGET - Application name
#
# OPTIONAL PARAMETERS:
#
# ATPROGRAM_PROGRAMMER - Name of programming hardware to use
# ATPROGRAM_INTERFACE - Name of programming interface to use
# ATPROGRAM_PORT - Name of communication port to use
#
# PROVIDED VARIABLES:
#
# (None)
#
# PROVIDED MACROS:
#
# (None)
