| 7 # You should at least check the settings for | |
| 8 # DEVICE ....... The AVR device you compile for | |
| 9 # CLOCK ........ Target AVR clock rate in Hertz | |
| 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. | |
