good tutorial for programming AVRs?

Hi - I finally have the capability to write programs to AVRs. It has been quite the challenge to get to this point! So now - can anyone point me to a good tutorial on how to program AVRs? From everything that I've read - it would be best for me to start by learning assembler, and then later moving on to C. By the way - my only programming experience is with VB6 (though I haven't touched VB for over a year now) So - can anyone point me in the right direction? Thanks a ton!!

Micro AVR programming tutorial (no pun intended):

Decide on a clock speed. The "strange" crystals (3.6864 MHz and so on) are better fits for standard serial rates; the next step up (e.g., 4) squeezes out a bit more performance.

Initialize the I/O ports: input or output, pull-up or not (for input), initial state (for output).

Initialize the peripherals that you may want to use: timers, UARTS, A/D, SPI, I2C, ...

Write code.

If you need a place to start, a good first program for any new microcontroller (sort of the equivalent of "Hello, World!") is to simply flash an LED at a 1 Hz rate using one if the timer peripherals. That requires getting to know an I/O port, a timer setup, and how to handle interrupts.

Atmel has just published Issue 1 of their Atmel Applications Journal, devoted to the AVR. There is some good introductory stuff in it. You should be able to subscribe via the web site.

I've enjoyed this site. You need to look past some of the grammatical / spelling mistakes due to translation from German.

If you are wanting to start out with assembler, Glen Hathaway has made several examples available here:
