Intellisense on VS2012

Hi

I used Visual Micro happily with VS2008 but have now plunged into VS2012. Both versions are still on my machine.

If I open a project in VS2008, I have zero errors. If I open the same project in VS2012, although I can build it, I get the maximum 100 errors, all of which look something like:

     99      IntelliSense: identifier "TIMER3C" is undefined

Is there something else I should do in the land of VS2012?

I have checked the associations for ino and pde to VC++ and that's fine.

David

Hi David,

When you enter code are the intellisense prompts correct? For example do you see the correct list of Serial ports when you type "Ser"?

Is "Go To Definition/F12" working?

Thanks

Hi Tim

Yes, the intellisense prompts are correct.

Yes, "Goto definition is fine"

I do not know what F12 should do. It seems a bit random.

I have just realised that a lot of the errors are in "pins_arduino.h" if that helps. If I double click an error, it takes me somewhere random. If I double click the same error again, it takes me somewhere else random.

Hi David,

We normally suggest people close the intellisense errors list and ignore it. the list differs in the various VS versions. It attempts to report MS C++ syntax errors, some of the Arduino core and some sketch code can use slightly different syntax.

Oh. OK.

Is there a way to filter out intellisense errors so that you can see the real errors?

Probably or maybe. Sorry I haven't tinkered with it directly.

Future versions of vm will certainly provide more flexibility in this area.

But how come it hasn't come up before?

I'm sure I'm not the first to use VS2012 with a project with TIMER3 etc and why the random jumping about and strange things like:

     8      IntelliSense: expected a ';'      

Surely, if that was a real error it would not compile. 

Anyway, a right click reveals a checkitem "Show intellisense errors" and so they can be removed. Odd, though.

It has come up before in all VS versions. Everyone just closes the intellisense error list.

I would be nice if it worked. When there is time we will experiment with some more vs settings and if required vm can add more gcc defines that VS will understand. Other than that we would need to write a gcc language system for VS so that we avoid the standard VS C++ stuff.

Atmel Studio is a better in this area because it is designed for the Arduino chips, however Atmel has other weaknesses compared to VS so I think 2012 is the best option for now. Having said that VS2008 opens so quickly that it always seems like a breath of fresh air  Smiley
