# LUFA HID Bootloader Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
# Provides a set of targets to re-program a device currently running a HID
# class bootloader with a project's FLASH files.
# -----------------------------------------------------------------------------
# TARGETS:
#
# hid - Program FLASH into target via
# hid_bootloader_cli
# hid-ee - Program EEPROM into target via a temporary
# AVR application and hid_bootloader_cli
# teensy - Program FLASH into target via
# teensy_loader_cli
# teensy-ee - Program EEPROM into target via a temporary
# AVR application and teensy_loader_cli
#
# MANDATORY PARAMETERS:
#
# MCU - Microcontroller device model name
# TARGET - Application name
#
# OPTIONAL PARAMETERS:
#
# (None)
#
# PROVIDED VARIABLES:
#
# (None)
#
# PROVIDED MACROS:
#
# (None)
#
