2.4 Toolchain

In order to build an application from the source code, a toolchain is needed, which

includes required tools such as an assembler, compiler, and linker. The code for this

kit is compatible with the Atmel AVR GNU and IAR AVR toolchains.

2.4.1 AVR Assembler 2

Integrated i

n Atmel AVR Studio 5 is the Atmel AVR assembler. The assembler works

on source files containing instruction mnemonics, labels and directives. It generates

fixed code allocations, consequently no linking is necessary.

2.4.2 AVR GNU Toolchain

Integrated

in AVR Studio 5 is the AVR GNU toolchain extension. It includes all the

necessary tools, such as C/C++ compiler, assembler and linker, for AVR application

development.

2.4.3 IAR AVR Toolchain

This i

s a commercial toolchain that includes all the necessary tools, such as C/C++

compiler, assembler, and linker, for AVR application development. A 30-day

evaluation version as well as a 4k (code size limited) kick-start version is available

from the IAR website.

2.5 Programmers and debuggers

Programmers and debuggers are needed when either the application is programmed

without using the boot loader or when debugging support is needed. Several different

tools are available that can be used directly with the Atmel AVR Xplained kit. The

most common tools are described in the following chapters.

AVR Studio 5 manages all the following programmers/debuggers.

2.5.1 AVR JTAGICE 3

Atmel AVR JTAGICE3 i

s a mid-range debug/programming tool that can be used for

programming and debugging of Atmel 8-bit and 32-bit AVR microcontrollers and kits

including the Atmel AVR XMEGA-B1 Xplained kit.

2.5.2 AVR JTAGICE mkII

Atmel AVR

JTAGICE mkII is a mid-range debug/programming tool that can be used

for programming and debugging of Atmel 8-bit and 32-bit AVR microcontrollers and

kits including the XMEGA-B1 Xplained kit.
