This is a GUI for AVRDUDE (http://savannah.nongnu.org/projects/avrdude).
https://blog.zakkemble.net/avrdudess-a-gui-for-avrdude/
Requires .NET Framework 2.0 SP1 or newer. All systems since Windows Vista will have the required version already installed.
Can be ran using Mono (http://www.mono-project.com).
Has not been tested on macOS, but should work. Might need the --arch=32 argument.
mono --arch=32 avrdudess.exe
Install Mono (this is the minimum required, you can use mono-complete for a full install):
sudo apt-get install libmono-system-windows-forms4.0-cil
On older versions of Ubuntu you might need to use libmono-winforms2.0-cil instead.
Install AVRDUDE and AVR-GCC (for avr-size):
sudo apt-get install avrdude gcc-avr
Run AVRDUDESS with mono, you might have to run as root (sudo) so that AVRDUDE can access ports if you haven't changed any permissions or rules.d stuff:
mono avrdudess.exe
You will need Microsoft Visual Studio 2015 or newer installed (older might work too). Open ./src/avrdudess.sln and click the 'Start' button at the top and it will build and run AVRDUDESS.
You can find the output in ./src/avrdudess/bin/Debug/, or ./src/avrdudess/bin/Release/ if you chose to build for Release (the drop down box second from the left of the Start button is where you can choose the configuration).
You will need Inno Setup installed. Once you've used Visual Studio to build the Release version of AVRDUDESS, run ./installer/installer.bat and the installer exe will appear in the same directory.
