6 # This is a prototype Makefile. Modify it according to your needs. | |
7 # You should at least check the settings for | |
8 # DEVICE ....... The AVR device you compile for | |
20 | 9 # CLOCK ........ Target AVR CLOCK rate in Hertz |
0 | 10 # OBJECTS ...... The object files created from your source files. This list is |
11 # usually the same as the list of source files with suffix ".o". | |
12 # PROGRAMMER ... Options to avrdude which define the hardware you use for | |
13 # uploading to the AVR and the interface where this hardware | |
14 # is connected. We recommend that you leave it undefined and | |
15 # add settings like this to your ~/.avrduderc file: | |
16 # default_programmer = "stk500v2" | |
17 # default_serial = "avrdoper" | |
18 # FUSES ........ Parameters for avrdude to flash the fuses appropriately. | |
