AVR-Chat

It's all in the datasheet.  I suggest you look there first and write 
your code.  Then if you have problems getting your code to work you can 
ask specific questions,  maybe post your code and we'll try to help you.

Grandpa always told us when we were kids that when you need a hand, look 
at the end of your own arm first.

If you're in school, we aren't interested in doing your work for you 
unless we share your grade...and since most of us are finished with 
school, we don't need or care about grades on assignments or class projects.

If you're working on a product and want us to do all of the work for 
you, you need to be willing to share your profits...most of them, 
actually.  Most of us who do embedded processor work are in a position 
such that if we no workie we get no checkie...the corollary to that is, 
no checkie no workie.

Look on the end of your arm first.
