avr-common

This is my small library of utilities for AVR microcontroller development.

build

This directory contains Makefile snippets to abstract out a lot of common building stuff. I generally build my software using the following tools:

• avr-gcc for compiling

• avrdude to control the programmer

• AVR JTAGICE3 programmer

There are a set of microcontroller-specific files; these contain a few parameters that are specific to each chip.

To use the build files, you just need to add the following two lines to the top of your project Makefile:

AVR_ROOT        =       ../../avr-common
MCU             =       <insert-microcontroller-type>

At the end of the Makefile, add the following:

include $(AVR_ROOT)/build/avr-build.mk

modules

Some modules to support various bits of hardware etc. To add one of these to a project, you need to add it to the MODULES definition in the Makefile, for example:

MODULES         =       ds1820

You’ll also need to include the corresponding header file (e.g. ds1820.h) in the source file[s] that uses the module.

include

Some useful common include files. Also contains the header files for various modules.
