AVR Tutorial

There's a lot of good information out there about programming micro-controllers, but I couldn't find a good, stepwise, lesson-based tutorial. Since a bunch of the HacDC folks are just learning their way around, I thought it'd be fun to put together a mini-course based on the Atmel AVR platform and GNU-GCC. The idea is to have each lesson doable in an hour or so

What follows is a mix of how-to and code snippets and peoples' experience walking through it all. If you're following along and want to contribute, feel free.

The Basics (take these in order):

AVR Lesson: Setup: Get a programmer, a chip, the software, and some parts

AVR Lesson: Output Pins I: Basic output and LED Blinky example

AVR Lesson: Output Pins II: Binary math and Cylon Eyes

AVR Lesson: Input Pins: Debouncing and Button-triggered Cylon Eyes

AVR Lesson: Timers: Clocks and how to use them.

AVR Lesson: Interrupts:

AVR Lesson: Pulse-width Modulation: An easy way to get analog outputs. Dimming LEDs or Crossfading Cylon Eyes

AVR Lesson: Analog-digital Conversion: Automatical Dimming Night Light

Advanced Material (mix-n-match):

AVR Lesson: Watchdog Timers:

AVR Lesson: Using Program Memory:

AVR Lesson: Motor Driving:

AVR Lesson: Servo Control:

AVR Lesson: State Machines:

AVR Lesson: Sound:

AVR Lesson: Serial I/O:

AVR Lesson: USB:
