The Tinyfox Software that you can download from this page contains already the objectfile that can be flashed into the microcontroller. You need a compiler ony in case you modify the sourcecode, e.g. Atmel's AVRASM2 compiler. The compiler cannot be obtained stand-alone, but as part of Atmel's AVR Studio 4.

To flash the compiled software into the microcontroller, you need a programmer software. We use SP12 (released under the GPL).
