=== Installing and confguring the tools  ===

This section describes what you need to program the chip. First you need the toolchain with the compiler which translates your program text into bits and bytes that the controller can execute. We are using the GCC compiler which is  part of the [http://winavr.sourceforge.net WinAVR] (Windows) and [http://www.obdev.at/products/crosspack/index-de.html CrossPack-AVR] (Mac).

If you use Windows download [http://sourceforge.net/projects/winavr/files/WinAVR/20100110/WinAVR-20100110-install.exe/download WinAVR] and follow the installtion guide. When the installer asks to make an entry in the PATH variable be sure this is checked.

For a mac you have to download [http://www.obdev.at/downloads/crosspack/CrossPack-AVR-20100115.dmg CrossPack AVR]. The toolchain is installed into /usr/local/CrossPack-AVR <ref>/usr/local/CrossPack-AVR is just a symbolic link to /usr/local/CrossPack-AVR-20100115 or something like that.</ref>. Have a look if the installer did add an entry to the PATH variable by typing the following line in your shell (Terminal):

<pre>echo $PATH</pre>

If it doesn't contain ''/usr/local/CrossPack-AVR/bin'', execute this in your shell:
<pre>echo -e " \n \n export PATH=/usr/local/CrossPack-AVR/bin:$PATH" >> ~/.profile</pre>

TODO: Build flash the USBasp with a firmware that AVR Studio supports and then describe how the studio works 
Then download the [[AVR Studio || http://www.atmel.com/forms/software_download.asp?family_id=607&fn=dl_AvrStudio4Setup.exe]]
-->

For both '''Windows''' and '''Mac''' chose a good editor like [http://notepad-plus-plus.org/ Notepad++] or [http://www.pnotepad.org/ Programmers Notepad] for Windows and [http://www.barebones.com/products/textwrangler/ TextWrangler] for Mac.
