I work at the Moment on a Desktop Software called "pedalSHIELD Updater".
You can find attached a screenshot of it.
With these tool you can upload precompiled sketches to your pedal.
Just select COM-Port, Arduino Type and the precompiled sketch and press the big Button.
You don't have to start an IDE. Just transfer.
It's great for musicians without any knowledge about software developing.
I also work on an AndroidVersion. Connect your pedal via USB with your phone and
change the pedal software in seconds, also live on stage !
