As far as i know, footswitch is true bypass. Meaning, if its set to bypass mode, the signal will go from the input directly to the output of pedalshield, thus there is no need for software programming.

yes, as nik said it is true bypass, meaning that when the effect is off or bypassed the guitar signal goes straight from input to output.
The pin7 of the DUE will "feel" when the 3pdt footswitch is activated or not, the pin will be high when the effect is not working and low when is on.
You can have a look at this for more info:

Can you describe how a 3pdt footswitch is wired? There are 9 pins but from the picture in the forum link you provided, only 6 are used...

I found this image searching for this topic..



But this image made matters even more weird...

I hope this image helps you:
- The green is the signal flow then the effect is not working (true bypass mode).
- The red flow is when the pedal is engaged.





The 3PDT works connecting the middle row pins with the top pins or bottom pins depending if is pushed or not, check this again:

And how exactly does the pin7 know that it is active ?
