| 66 | # AVR-LibC's avr/io.h uses the device specifying macro to determine |
|---|
| 67 | # the name of the device header. For example, -mmcu=atmega8a triggers |
|---|
| 68 | # the definition of __AVR_ATmega8A__ and avr/io.h includes the device |
|---|
| 69 | # header 'iom8a.h' by means of: |
|---|
| 70 | # |
|---|
| 71 | # ... |
|---|
| 72 | # #elif defined (__AVR_ATmega8A__) |
|---|
| 73 | # # include <avr/iom8a.h> |
|---|
| 74 | # #elif ... |
|---|
| 75 | # |
|---|
| 76 | # If no device macro is defined, AVR-LibC uses __AVR_DEV_LIB_NAME__ |
|---|
| 77 | # as fallback to determine the name of the device header as |
|---|
| 78 | # |
|---|
| 79 | # "avr/io" + __AVR_DEV_LIB_NAME__ + ".h" |
|---|
| 80 | # |
|---|
| 81 | # If you provide your own specs file for a device not yet known to |
|---|
| 82 | # AVR-LibC, you can now define the hook macro __AVR_DEV_LIB_NAME__ |
|---|
| 83 | # as needed so that |
|---|
| 84 | # |
|---|
| 85 | # #include <avr/io.h> |
|---|
| 86 | # |
|---|
| 87 | # will include the desired device header. For ATmega8A the supplement |
|---|
| 88 | # to *cpp would read |

| 89 | # |
