#Name: Makefile

# This is a prototype Makefile. Modify it according to your needs.
# You should at least check the settings for
# DEVICE ....... The AVR device you compile for
# CLOCK ........ Target AVR clock rate in Hertz
# OBJECTS ...... The object files created from your source files. This list is
# usually the same as the list of source files with suffix ".o".
# PROGRAMMER ... Options to avrdude which define the hardware you use for
# uploading to the AVR and the interface where this hardware
# is connected. We recommend that you leave it undefined and
# add settings like this to your ~/.avrduderc file:
# default_programmer = "stk500v2"
# default_serial = "avrdoper"
# FUSES ........ Parameters for avrdude to flash the fuses appropriately.
DEVICE = attiny84
CLOCK = 8000000
PROGRAMMER = -c usbtiny -b 9600
OBJECTS = ATTiny_SDI_12.o SDI12.o
FUSES = -U lfuse:w:0xC2:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m
# ATTiny84 fuse bits used above (fuse bits for other devices are different!):
# Fuse low byte:
# 0x24 = 0 0 1 0 0 1 0 0
# ^ ^ \ / \--+--/
# | | | +------- CKSEL 3..0 (8M internal RC)
# | | +--------------- SUT 1..0 (slowly rising power)
# | +------------------ BODEN (if 0, brown-out detector is enabled)
# +-------------------- BODLEVEL (if 0: 4V, if 1: 2.7V)
#
# For computing fuse byte values for other devices and options see
# the fuse bit calculator at http://www.engbedded.com/fusecalc/
