| where can I find a detailed reference of how to write C for AVR GCC? I read that AVR GCC is ported GCC and I'm trying to learn how to port code from codevision. I have found the codevision manual, but can't seem to find an AVR GCC equivalent (except the normal GCC manual)... |

Look for the avr-libc manual.
The main differences are ISR declarations, the "PORTC.x" construct, and the handling of flash/eeprom variables. |

I just run a sed script to convert between CodeVision and avr-gcc. However you always need to do some hand-editing.
You write C for avr-gcc in conjunction with the avr-gcc manual.

When you installed avr-gcc you also installed the documentation. You can always Google an online version.
No, the avr-gcc docs are not as well organised as the CV docs. But hey-ho, it is free.

And it's within the remit of anyone who cares to modify them into a "better" form. That's the nature of collaboratively developed software. |
