The intellisense and the build system are different

Can you confirm build happens correctly and same as arduino ide?

Then confirm what board/toolchain you are using?

Thanks

Great

What is the exact line of code that shows an intellisense error?

Thanks, I will add an intellisense workaround for that in the next release

If you put the attached file in the project/_vm folder then build it adds an intellisense patch that removes the red line. The build is only required to detect the new .h file. The .h does not have to be #included in your code.

I have removed my last message so that you can re-read my previous message (also see the vs-intellisense-fix.h that is attached to the message)

Please post your code as text with numOfPins defined

Also confirm arduino ide version or switch on vmicro>compiler>show build properties and verbose then email the output as .txt file along with lonk to this post.

Also confirm name of board "Arduino/Genuino Micro"?

I have looked into this some more. You are using low level gcc calls and we are fighting with visual studio c++ intellisense. I will update visual micro over the next few days to try to make things better in visual studio but because you are using atmel hardware you should install atmel studio and the visual micro extension. 

Atmel studio is actually visual studio 2015 + Gcc intellisense. 

Atmel should work better but the next release of visual micro will also ensure we don't try to confuse things in atmel studio by applying vs intellisense fixes. 

If you are going to work with gcc which is advanced arduino I think atmel studio is a better option for you anyway.

Excellent. 

tip: You do not need to copy/add stdarg.h to an arduino project. It is part of the core so you can just add the #include where needed
