Product Description

The STK128+ is a complete, cost-effective development board for the ATmega128. It is designed to provide designers a quick start to develop code for the ATmega128 MCU, expediting the prototype development of ATMega 128 devices.

The ATmega128 chip is mounted on a device board, which can be separated from the motherboard, allowing the secure exchange of the MCU. The ATmega128 chip comes in a TQFP64 package and can be the ATmega128-16AU, ATmega128L-8AU, or ATmega128A-AU.

The STK128+ package comes with an ATmega128 device board, an additional spare ATmega128 device board, and an Experiment Fittings Pack.

The AVR microcontroller from Atmel (now Microchip) is one of the most widely used 8-bit microcontrollers. Arduino Uno is based on AVR microcontroller. It is inexpensive and widely available around the world. This book combines the two. In this book, the authors use a step-by-step and systematic approach to show the programming of the AVR chip. Examples in both Assembly language and C show how to program many of the AVR features, such as timers, serial communication, ADC, SPI, I2C, and PWM.

The text is organized into two parts:

  • The first 6 chapters use Assembly language programming to examine the internal architecture of the AVR.
  • Chapters 7-18 uses both Assembly and C to show the AVR peripherals and I/O interfacing to real-world devices such as LCD, motor, and sensor.

The first edition of this book published by Pearson used ATmega32. It is still available for purchase from Amazon. This new edition is based on Atmega328 and the Arduino Uno board.
