ATMega32 tutorials in C

Introduction

The Atmel AVR microcontroller series have a broad varieties of resources. We can choose any part number containing the resources we need for project development. In this tutorial, I choose ATMega32. It come with 40-pin DIP package with sufficient resources for learning and project development.

For the software development tool, I choose the vendor's tool, Atmel Studio.

Some AVR micro-controllers I posses.
They come with DIP package, ease of prototyping.

Atmel Studio is a software integrated development environment (IDE) support for development the firmware Atmel AVR microcontroller series and 32-bit ARM. Now it's owned by Microchip. Atmel Studio succeed its older version AVR Studio. Currently, the latest version is Atmel Studio 7. In the IDE we can program the Assembly or C language. The C compiler depends on AVR-GCC.

Atmel Studio 7 I use for this tutorial.
