Programming AVR Microcontrollers in C


Originally recorded March 18, 2014: "Beyond the Arduino: Programming AVR Microcontrollers in C".

In this webcast, we'll dive straight into the deep end. I'll show you what you need to get started programming the AVR ATMega (and ATTiny) series microcontrollers, give you an overview of their built-in peripherals, and demonstrate most of the important functionality. And while the focus of this webcast is on Atmel's AVR series, nearly everything you'll learn here is transferable to other microcontrollers.

Elliot Williams is a Ph.D. in Economics, a former government statistician, and a lifelong electronics hacker. He taught himself to program microcontrollers long before there was any such thing as an Arduino, and loves to spread the knowledge. Most recently, he is author of the Maker Media book "Make: AVR Programming, Learning to Write Software for Hardware", which is chock full of microcontroller-programming tidbits and thick enough to stun a rhino.


Make: AVR Programming: Learning to Write Software for Hardware

Atmel's AVR microcontrollers are the chips that power Arduino, and are the go-to chip for many hobbyist and hardware hacking projects. In this book you'll set aside the layers of abstraction provided by the Arduino environment and learn how to program AVR microcontrollers directly. In doing so, you'll get closer to the chip and you'll be able to squeeze more power and features out of it.

Each chapter of this book is centered around projects that incorporate that particular microcontroller topic. Each project includes schematics, code, and illustrations of a working project.
  • Program a range of AVR chips
  • Extend and re-use other people’s code and circuits
  • Interface with USB, I2C, and SPI peripheral devices
  • Learn to access the full range of power and speed of the microcontroller
  • Build projects including Cylon Eyes, a Square-Wave Organ, an AM Radio, a Passive Light-Sensor Alarm, Temperature Logger, and more
  • Understand what's happening behind the scenes even when using the Arduino IDE
