Debugging and VS2008

I've been using the debugger with VS2008, visualisations and all. It is going well so far. There is an occasional "Visual Studio has had to close blah blah" but generally OK. 

I set a breakpoint in an interrupt sub-routine (just to see what occurs) and that broke it, which isn't surprising and a reminder that good practice is to set a flag in the ISR and then put the processing code in the main loop.

No complaints at all, though. Very smart, very clever, very useful.

Great. Good to hear 2008 is working. Thanks for testing it.

I hope to nail any remaining issues over the next few weeks. I'll do some vs2008 testing at the same time.

And yes you are right, you can only set breakpoints where you can normally use Serial.print(). 

Breakpoints in interrupts and global class initializers will fail (or crash the Arduino). But it will be obvious immediately when the program runs?

Ok I must be missing something. I have installed the plugin for debug but I cannot debug any projects. I also cannot see the same project properties window that is shown in the video tutorial. I always get the standard vs2008 project properties windows. I have already used the arduino plugin to code and compile projects successfully but I cannot see the debugging options. Do you have a link on how to setup an arduino project for debugging? Thanks

Hi, it is a bit confusing because VS has "Property Pages", "Properties Window" and "Property Manager"

We need to make sure you are using the right one. The one you want is "Property Window". 

It is normally access from the "View" menu or by pressing F4. It should be a small tool window that appears docked within the IDE and normally below the Solution Explorer. It should have a title of "Properties"

Can you see the "Property Window"?

Thanks

OK thanks for that. 

All is well now with the debugger except when I set the debugger option "Enable Break/Pause" to true. 

When I do this and recompile I get the following error messages. Obviously something about "avr-objcopy".

What causes this and what is the trick to setup step by step debugging or break and pause debugging?


Compiling 'Blink' for 'Arduino Mega 2560 or Mega ADK'

Yes got a but fix due over the next few days for that. It crept into the last version. 

From memory, I think that problem happens for breakpoints that do not have WhenHit" messages with variables such as 

Hello World i={i}

or
{i}{someVar}{anotherVar}

etc
