AVRFusesCalc overview

AVRFusesCalc is an application through which we can easily set the fuse bits and lock bits in the micro-controllers ATmega and ATtiny from Atmel. To be able to set fuse bits should be installed on the "avrdude". "AVRFusesCalc" recognizes the connected micro-controller and loads its settings, regardless of the clock speed. It can also determine what programming protocol, SPI or TPI, is required for communication with the micro-controller.
