Hello everybody,

I got an at91sam7x evaluation board but I am a newbie in the arm field.
I just got the getting started example from atmel running but it would
be very good to learn more gcc basics. E. g.

- how to switch on a led by pushing a button
- how to adjust the data direction
- how to set a port pin high
- etc.

I am wondering, if there are a lot of differences between avr's and
arm's. What I have to know in this matter and where can I find short
information (except the datasheets). Maybe somebody knows tutorials or
some basic examples?

I would be very thankful for every getting started information.

Best Regards



HFQ

Look for the SAM7S sample from Martin's sample. IT's the same core
except that sam7x have en ethernet card.

The code is compatible between both
