Breakpoint not working on .cpp ?

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  Sad Sad

Hi,

Try giving the local cpp/h different names so that we avoid possibility of confusion with the library of the same name.

Thanks

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?

Hi,

Sorry the docs are a bit weak about this.

No the debugger does not work in libraries

Yes it works in cpp files of the local sketch folder. Ensure breakpoints are in code where it would normally be possible to send serial messages (ie: not in code that initializes before the arduino core has initialized)

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?

Hi,

Sorry the debugger uses Serial (or SoftwareSerial etc) which do not work inside interrupt code.

You would need a hardware debugger for that.
