Hello,

VM seems to import wrong prototypes. Many prototypes of standard functions (e.g. sprintf(...)) are surrounded by a macro named _EXFUN. There is something going wrong with this macro: it expends to sprintf() with no paramters. Now Visual Studio (Intellisence?) grumbles "too many parameters".

There are a lot of defines to configure _EXFUN. I do not know how to fix it. Can anybody help?

Edit: My actual configuration is:
- Windows 10
- Visual Studio 2012, Update 5
- Arduino IDE 1.6.7
- ESP8266 Build-In 2.0.0
- Visual Micro 1.1601.11

Thanks for the example.

I think I have found the solution. I have added #define __STDC__ to the esp8266 intellisense list.

You can edit the vm config to test. To find the vm install folder look in "tools>options>visual micro>version>assembly"

Then edit the text file called "[visual micro program folder]\Micro Platforms\arduino16x\hardware\esp8266\intellisense code.h"

Add this line to the top of the file and save it.

#define __STDC__ 

In visual micro, clicking save on the project or building should refresh the intellisense, otherwise toggle the board selection with another board.

The code from the "intellisense code.h" is inserted into the "__vm\[project_name].vsarduino.h" file of each esp8266 project.

Does this make sense?
