Hi Jan,

We are looking at giving you more control from the UI over all elements of the build process.

Yes you are right, I am no expert but I hear that the Arduino defaults are not the most optimized but are designed to work for all code uses.

You can change the settings in an arduino 1.5 Ide and/or it is also possible to create your own entire platform definition that shares the tool chain of the default (read more on arduino.cc for the latter)

If you open arduinoide/hardware/arduino/avr/platform.txt and boards.txt with a text editor, such as notepad++, you can alter the settings. 

Look for the ".pattern" properties in platform.txt. The system simply merges {properties} that are defined from within boards.txt and platform.txt.

You can also create your own board in boards.txt by copying and "renaming.". There are a few board level flags but not enough so hacking the platform.txt patterns directly is more flexible but affects every avr compilation.

If you alter the config you can click "tools>visual micro>reload tool chains" or restart the ide


Another option, maybe for the future

If you want to keep a normal arduino ide config and a seperate optimized ide and you have a visual micro + license then you can extend the apps list with your own Ide registration such as "Arduino 1.5.x Optimized"
