The software to control the Tinyfox Transmitter is located in the flash of the microcontroller.
The software was released by me (DL3SDO) under the GNU General Public License (GPL), version 3.
This means that you are allowed to modify the software and/or use it for your own projects,
but only if you again release the software under the GPL !
This e.g. means that you
A detailed description of how to assemble the software and to flash the µC can be found in the Documentation
and in Programming.
The Tinyfox Software that you can download from this page contains already the objectfile that can be flashed into the microcontroller. You need an assembler only in case you modify the sourcecode, e.g. Microchip's (formerly Atmel's) AVRASM2 assembler. The assembler cannot be obtained stand-alone, but as part of Microchip's Atmel Studio.
