Hi,

I would like to debug an arduino apps which include a library. I know we can't debug library but if I include on source files the .cpp, is it possible to have breakpoint working ? If so how, i am stuck 

I am using the debugger for the 1st time, and I also cannot get breakpoints to work in my .cpps (these are my personal libraries I and debugging). I saw this comment:

But can not find anywhere in the documentation to confirm this. 

A breakpoint in my .ino sketch does work. Before I move all my code around: does all the code need to be in the same sketch folder for debug to work?

I moved the library to the sketch folder and now the breakpoints report a variable's value. However, I need to check values inside my timer interrupt service function. When I add a breakpoint inside this function, NO debug breakpoints work. (Serial.print() has the same problem). 

I am putting these variables in a class/public then checking them repeatedly inside loop(). Is there any way I can report the values directly from inside the interrupt service function?
