I am having trouble getting started.

What is the best method of learning AVR programming
with GCC? Is it to just read through the avr-libc
manual and buy a C book? Are there any additional aids
out there?

After I've gotten started, what method have you guys
used to program a certain AVR CPU? For example, I
assume you make use of the data sheet for the specific
processor. But do you really read through all 300+
pages (at least thats the case with mega32) of the
specification? That seems exhaustive and boring.
Perhaps you could enlighten me on some simpler

Thank you...

In all cases of programming the "hello world" program is always a good start.
On Microcontrollers I would devide this in three steps:
HelloWorld_A would be a blinking Led, controlled by an Port Pin
HelloWorld_B would be a microcontroller connected to uart transceiver (Maxim232 et al.) to a PC HelloWorld_C would be a interrupt controlled Led blinker (e.g. Timer interrupt, or PWM)

But datasheet reading should not be considered boring, the interesting parts will blink in your eyes :) and the "boring" parts will be reminded by you for later reading.

Especially if you want to use AVRs to do your work, AVRFREAKS.COM is a great place to start, and some other forums, too (like http://www.mikrocontroller.net for starters)
