+# 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.

+#        ^ ^ ^ ^   ^ ^ ^------ BOOTSZ0
+#        | | | |   | +-------- BOOTSZ1
+#        | | | |   +---------- EESAVE (set to 0 to preserve EEPROM over chip erase)
+#        | | | +-------------- CKOPT (clock option, depends on oscillator type)
+#        | | +---------------- SPIEN (if set to 1, serial programming is disabled)
+#        | +------------------ WDTON (if set to 0, watchdog is always on)
+#        +-------------------- RSTDISBL (if set to 0, RESET pin is disabled)
+# 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)
