Makefile

# makefile, originally written by Guido Socher

# rewritten by Ramunas Girdziusas, December 2010.
# Removed compiling and linking of anything but eth_rem_dev.hex, which
# is now main.hex. Included linking of adc_m88.c and adc_m88.h. 
# Writing to flash is done strictly with avrdude and the stk200 interface.
# The setting lfuse:w:0x60:m is essential as the clock is external: 
# ENC28j60 Pin 3 (CLKout) is connected to ATmega88 Pin 9 (PD5, XTAL1).
