Ambiguous symbol byte

My static analysis tool is warning me about multiple definitions of the "byte" type.

The generated file .${PROJECT}.vsarduino.h contains a type definition for "byte"
typedef unsigned char byte;

Then it includes the main arduino header file
#include <arduino.h>

That file makes a different definition for "byte":
typedef uint8_t byte;

The "uint8_t" type is defined in ...\arduino-1.6.6\hardware\tools\avr\avr\include\stdint.h as

typedef unsigned int uint8_t __attribute__((__mode__(__QI__)));

Hi,

The one in vs arduino needs to be removed. 

Visual micro started adding it some time ago because intellisense wasn't picking it up.

I will remove it for the next release.

You can remove yourself if you want to. The intellisense.code.h is simply a kick for the intellisense system and doesn't affect compile. In recent months Visual Micro has extended it's auto discovery of toolchain locations so gradually the intellisense.code.h becomes redundant. 

[visual micro location]\Micro Platforms\arduino16x\hardware\avr\intellisense.code.h

You can find the "visual micro location in tools>options>visual micro>system>assembly"

We will shortly move to using the new clang capabilities of visual studio which will entirely remove the need for the intellisense.code.h

Click the Rescan button on the explorer if you edit the .h or restart the ide.
