One problem at the moment is that Admin is currently in Thailand where he has a secret lab or something. So he's been scare the last few weeks :/
In theory, giong through the code tutorial for the Axon 2 in general will tell you what to do, but I'm not going to double check that myself
Have you installed AVR Studio and WinAVR per the instructions, at least?
To quote your private message for others' info:
From my understanding, AVR Studio is used to debug the code, and WinAVR is used to actually compile it...and in my experience in downloading code to microcontrollers using Keil uVision, there was a hyperterminal that used the final hex file...which again, is something unexplained in the SOR tutorial provided.
WinAVR is the building blocks that AVR Studio uses, basically. AVR Studio is where any coding is usually done, and also where the code is compiled. To use AVR Studio for this do the following:
-Put all the files from that .zip you've already found into one folder.
-If AVR Studio is installed, the VR_Axon2_demo.aps file should automatically open into AVR studio. This is the AVR Studio project file...
-In AVR Studio, you should be able to open the VR_Axon2_demo.c file. It'll be listed in the Source Files folder. Don't modify anything yet, though.
-In the build menu, select Build. (or press F7). You'll get some output at the bottom... either indicating success or failure.
Let us know what happens when you try these steps. I might be missing something basic, namely that AVR Studio might need some configuration per the tutorials...
With properly compiled code, you can use FBOOT17.exe on non-64bit windows machines to load the created .hex file to the Axon 2. I'm not sure why Admin gives instructions to use a hardware programmer on the Instructables... Note that the .hex file can't have a THISISNAME.hex where THISISNAME is longer than 8 characters or FBOOT will cryptically fail. Instructions for using FBOOT are in the Axon 2 tutorials, so I won't elaborate (I'd have to look it up anyways, so you can do that
