# 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 = attiny85
CLOCK = 1000000
PROGRAMMER = #-c stk500v2 -P avrdoper
OBJECTS = main.o
FUSES = -U hfuse:w:0xdf:m -U lfuse:w:0x62:m
# ATtiny85 fuse bits used above (fuse bits for other devices are different!):
# Example for 1 MHz internal oscillator
# Fuse high byte:
# 0xdf = 1 1 0 1 1 1 1 1
# ^ ^ ^ ^ ^ \-+-/
# | | | | | +------ BODLEVEL 2..0 (disabled)
# | | | | +---------- EESAVE (EEPROM not preserved over chip erase)
# | | | +-------------- WDTON (watchdog not always on)
# | | +---------------- SPIEN (serial programming is enabled)
# | +------------------ DWEN (DebugWIRE disabled)
# +-------------------- RSTDISBL (RESET pin enabled)
# Fuse low byte:
# 0x62 = 0 1 1 0 0 0 1 0
# ^ ^ \ / \--+--/
# | | | +------- CKSEL 3..0 (8MHz internal RC)
# | | +--------------- SUT 1..0 (slowly rising power)
# | +------------------ CKOUT (clock output disabled)
# +-------------------- CKDIV8 (clock divided by 8)
#
# For computing fuse byte values for other devices and options see
# the fuse bit calculator at http://www.engbedded.com/fusecalc/
