It's a nice idea but there isn't a correlation between the defines in your code and actual pins.

It just so happens you have created a define with a value of 1 and it just so happens at some place in your code you use that to read or write a digital pin.

What might be an idea for us to consider if a local xml or json file where you can name your pins. Maybe there is some way to then make those definitions available to your code as #defines. That way the uncompiled and compiled sources would know the names/numbers of pins.

My suggestion would be to create something like a pins.h which contains all your #defines for all pins (and no other code). Then it will be easy to read your code to find a pin number. Maybe if we can find a pins.h the debugger can read that simple code to find some names.

Another idea is to use the @plot command instead of the digital pin viewer. Then you can plot only the pins you are working with using a breakpoint message with same syntax as the code:

Code:

@Plot.Pins.OtherPin.Red {digitalRead(#OTHER_PIN)} 

The @plot command shows On/Off in the charts quite clearly.
