App: AVRFusesCalc
Developer: Marcin Gibas
Genres: Utilities, Developer Tools

“AVRFusesCalc” is an application through which we can easily set the fuse bits and lock bits in the microcontrollers ATmega and ATtiny. To be able to set fuse bits should be installed on the avrdude and AVR-GCC package.
People using Arduino can use "avrdude" which comes with this application. The access path to "avrdude", is best set in the dialog panel in the "AVRFusesCalc" preferences. For more information how install avrdude from Arduino, please visit my website.
“AVRFusesCalc” recognizes the connected microcontroller 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 microcontroller.
Fuse bits can be set in two ways.
The first is the so-called “Simplified Fusebits”. This is ideal solution for beginners, who want only to select the clock and have no sufficient knowledge about fuse bits in AVR.
The important thing is that for 99,99 does not block the microcontroller using “Simplified Fusebits”.
The other way is fuse bits for advanced.
By using this option, you must have knowledge about individual bits which are available in a particular microcontroller.
Depending on the connected microcontroller we have access to the type of Low, High or Extended fuse bits and the Lock bits.
From version 2.2 it is possible to save to a file configuration fuse bits of a given microcontroller. In a situation where it would be necessary to configure another microcontroller, just upload the configuration from the file and then save these settings to the microcontroller. Of course, provided that the configuration loaded is intended for a microcontroller connected to the programmer.

The application has been tested with the programmer USBAsp and Arduino UNO.

I would like to ask you to evaluate the application in the AppStore. The comments will also be welcome. Thank you in advance for your time.

Release notes:
Fixed bugs.
