You will at least need '''AVRDUDE''' (AVR Downloader UploaDEr) to upload and download files to the Atmel chip. It is a command line interface (DOS). If you use Tido's programs then you don't need to compile anything: those programs are ready to be loaded. If you install WinAVR, AVRDUDE will be included. You can also install AVRDUDE separately. | You will at least need '''[http://www.nongnu.org/avrdude/ AVRDUDE]''' (AVR Downloader UploaDEr) to upload and download files to the Atmel chip.

It can read/write (download/upload) and it also has the required driver for USBasp in the installation. If you only want to write a new firmware (already compiled Tido's, DrJones's, ...) this should be all you need. | ||
You may also need to install a driver for your '''USBasp'''. I've used the cheap eBay USBasp pictured above ([http://www.fischl.de/usbasp/ a Fischl clone]) and latest driver from [http://sourceforge.net/projects/libusb-win32/ '''libusb-win32''' project]. Should work on all Windows 98 and newer. The software package has a wizard application, connect your USB device, run the wizard, select your connected USBasp and the wizard will generate a driver for that devices for you. Then install the generated driver by running it's installer. | You may also need to install a driver for your '''USBasp'''.

'''[http://www.atmel.com/tools/atmelstudio.aspx Atmel Studio]''' - Atmel Studio (newer AVR studio, it's been renamed) is available free from Atmel to allow you to write and compile programs and load them. It has a neat interface for some programming boards, but not USBasp (it seems it still can't upload using USBasp without external tool like AVRDUDE), so if you are using USBasp, you will still need AVRDUDE to actually upload the files. The latest version is called Atmel Studio 6 which runs on Windows and uses MS Visual Studio Shell and .NET 4.0 (both installed automatically). | '''[http://www.atmel.com/tools/atmelstudio.aspx Atmel Studio]''' - Atmel Studio (newer AVR studio, it's been renamed) is available free from Atmel to allow you to write and compile programs and load them.

''' | '''[http://winavr.sourceforge.net/ WinAVR]''' - WinAVR is a free collection of all the software you need as well as a graphical user interface (GUI) to edit, compile, and load programs. [http://www.eclipse.org/downloads/index.php Eclipse IDE for C/C++ Developers Eclipse IDE for C/C++ Developers] is another free GUI that goes on top of WinAVR (or MHV AVR) and is what Tido uses. It requires a plug-in that allows it to work with AVR. Follow instructions [http://interactive-matter.eu/how-to/developing-software-for-the-atmel-avr-with-avr-eclipse-avr-gcc-avrdude/ here] for installing WinAVR and Eclipse with AVR Eclipse plugin. Eclipse is optional. Then configure Eclipse for AVR. There is also a [http://avr-eclipse.sourceforge.net/wiki/index.php/The_AVR_Eclipse_Plugin Wiki] about Eclipse AVR. | ||

Right now, MHV AVR Tools seem to be up to date but eXtreme burner AVR has bundled older USBasp driver. | |||
If you want tiny code, use optimization for size for your compiler configuration. GCC uses "-Os" and you can find more useful optimizations and tricks via search on AVR Freaks or elsewhere. Sometimes older GCC versions generate smaller code than the newer ones. No idea how Atmel compiler compares to AVR-GCC. | |||
