AVR ATMEGA168P

Working Platform :
Lenovo Notebook , Intel Pentium Dual Core T2080 1.73GHz
2Gbyte RAM
Ubuntu 10.04 LTS- the Lucid Lynx

Hardware :
ATMega168P development kit from Akitsuki shop at Akihabara
(ＡＴｍｅｇａ１６８／３２８マイコンボードキット)

You may also require AVR-USBasp as a hardware programmer

From my own experience, AVR microcontroller is the most easiest to start and development ever.
Most of mcu I tried are still hanging with Windows platform but AVR is different.
Now I will show you how to settup development environment on Ubuntu Linux.

Let's do it

1. Install AVR build tools (binary utilities, compiler, library and chip writer)

#apt-get install binutils-avr gcc-avr avr-libc avrdude

2. Download and install eclipse and cdt plug-in

3. Install avr-eclipse, Just like they said at ...
http://avr-eclipse.sourceforge.net/wiki/index.php/Plugin_Download

4. Making new AVR project. At project properties, setting Post-build Command for making .hex file(where test-avr is your project name)
avr-objcopy -j .text -O ihex test-avr.elf test-avr.hex

5. At Target Hardware, select your target chip. In my case it is ATmega168p with 16 MHz clock

6. Eclipse plug-in seems to use AVR dude as a default hardware programer. At AVRdude -> Programmer Configuration, click Edit button.

Then select USBasp as your hardware programmer...

7. Unfortunately, my chip (ATmega168p) is not support by AVRdude for now ... So, I have to modify an AVRdude's configuration to support my chip.

Just like they said here ...

6. Connect your board with AVR USBasp, Writing code, Building .hex and download to the board. It's should work.
