==== Downloader/Uploader ==== | |||
You will at least need a downloader and uploader to modify the Atmel chip. | |||
'''[http://www.nongnu.org/avrdude/ AVRDUDE]''' - 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 MHV AVR Tools/WinAVR, AVRDUDE will be included. Does not support ATtiny13A, have to use a workaround and pretend it's ATtiny13. | |||
[http://extremeelectronics.co.in/avr-tutorials/gui-software-for-usbasp-based-usb-avr-programmers/ '''eXtreme Burner - AVR'''] - Or if you do not like AVRDUDE and want something with GUI, you can try eXtreme Burner - AVR, download latest version at the bottom of the page under release. 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. Does support ATtiny13A. | |||
==== USBasp Driver ==== | |||
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'''.

If you want to customize Tido's programs you will need a C compiler configured to work with AVR equipment. (Some people write AVR programs in assembly language which gives more compact programs, but you are on your own if you go that route.) You have one option: AVR-GCC. Either install it with everything you need from MHV AVR Tools (optionally older WinAVR) or install Atmel Studio that contains everything you will need as well apart from AVRDUDE, AVR Studio 6.1 or older can't upload via USBasp and you will need AVRDUDE or other downloader/uploader. | |||
==== Integrated Development Environments ==== | |||
'''[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://www.eclipse.org/downloads/index.php Eclipse IDE for C/C++ Developers]''' - is a free IDE that goes on top of AVRDUDE and AVR-GCC 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. Then configure Eclipse for AVR, [http://www.instructables.com/id/How-to-get-started-with-Eclipse-and-AVR/?ALLSTEPS you can see more in this different instructable]. There is also a [http://avr-eclipse.sourceforge.net/wiki/index.php/The_AVR_Eclipse_Plugin Wiki] about Eclipse AVR. '''AVR Eclipse seems to have glitches with latest Eclipse 4.2 Juno, use older Eclipse 3.6 or 3.7 instead'''. AVR Eclipse is again a little out of date. With 4.2 if you enter properties of your project and it wants to open with AVRDUDE settings showing it will not read them and throw you an error window, cancel and open it again, this time it will open with other settings showing and the AVR settings will load properly. I would advise you to get the latest version that AVR Eclipse plugin supports, not necessarily the latest Eclipse unfortunately. | ||
==== AVRDUDE, GCC, LIBC, ... ==== | |||
'''[http://www.makehackvoid.com/project/mhvavrtools MHV AVR Tools]''' - A WinAVR replacement since WinAVR development is stopped. It has newer AVRDUDE, AVR-GCC and AVR-LIBC along with other packages. It can be used in combination with AVR Eclipse or anywhere else the same way as WinAVR as an external tool like in Atmel Studio to provide AVRDUDE or compiler (AVR-GCC) to the studio. | '''[http://www.makehackvoid.com/project/mhvavrtools MHV AVR Tools]''' - A WinAVR replacement since WinAVR development is stopped.

'''[http://winavr.sourceforge.net/ WinAVR ''(not developed anymore)'']''' - 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. | |||

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. Atmel uses AVR-GCC in it's toolchain as well, usually an older stable version. | If you want tiny code, use optimization for size for your compiler configuration.
