AVR assembler makefile

makefile

#
# Simple Makefile for programming Atmel AVR MCUs using avra and avrdude
#
# Assemble with 'make', flash hexfile to microcontroller with 'make flash'.
#
# Configuration:
#
# MCU     -> name of microcontroller to program (see 'avrdude -p ?' for a list)
# TARGET  -> target board/programmer to use (see 'avrdude -c ?' for a list)
# DEVICE  -> linux device file refering to the interface your programmer is plugged in to
# INCPATH -> path to the AVR include files
# SRCFILE -> single assembler file that contains the source
#
 
MCU = m16
TARGET = stk500
DEVICE = /dev/tty.usbserial
INCPATH = /usr/share/avra/includes
SRCFILE = filename.S
