Microcontroller under control!

  • Basics of microcontroller construction, what are the possibilities of the Atmel Studio environment and the Xplained platform from ATmega168 / 328
  • Architecture and instruction set, or why microcontrollers are worth programming in C language
  • Efficient writing of simple and complicated programs on AVR, or how to use different tricks

AVR microcontrollers are a group of systems offering great possibilities. Every amateur electronics and programming knows that you can use them in a thousand ways, and the simplicity of construction, speed of operation, the richness of the periphery and many free tools make them all the more attractive gadgets. If you would like to explore the secrets of programming microcontrollers or to improve your own skills in this field, it's time to look into this book!

The new edition includes changes that have taken place in the world of AVR in the last 3 years, i.e. the change of AVR Studio to Atmel Studio. You will find the basics of using the new IDE, creating and debugging projects in it. You will learn more about the changes in the avr-gcc compiler, especially the so-called named address spaces, which facilitated access to data stored in the FLASH memory of the microcontroller. You will discover how to use TV remote controls to control a written program and how to combine a C program with an assembler. LED enthusiasts will understand how to handle multi-colored matrices using the peripherals available in AVR, and how to hardware exchange data with popular LEDs with the WS2812B driver. If you want the microcontroller to become your ally, you must read this book!
