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. |
