Identifier "D0" is undefinedC/C++(20)

[i3130002]

I'm using ESP8266 NodeMcu with Arduino and VS code and getting identifier "D0" is undefined C/C++(20) while it works pretty well after uploading.

Here is my configs:

c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "Arduino",
            "includePath": [

            ],
            "browse": {
                "path": [
                    "C:\\Program Files (x86)\\Arduino\\hardware",
                    "C:\\Program Files (x86)\\Arduino\\libraries",
                    "${workspaceRoot}"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            },
            "forcedInclude": [],
            "intelliSenseMode": "msvc-x64"
        },
        {
            "name": "Win32",
            "includePath": [
                "C:\\Users\\[USERNAME]\\AppData\\Local\\Arduino15\\packages\\esp8266\\tools\\**",
                "C:\\Users\\[USERNAME]\\AppData\\Local\\Arduino15\\packages\\esp8266\\hardware\\esp8266\\2.7.2\\**"
            ],
        }
    ],
    "version": 4
}

settings.json:

    },

        "unordered_map": "cpp",
        "vector": "cpp",

    ],
    "arduino.defaultBaudRate": 256000,
    // "C_Cpp.intelliSenseEngine": "Tag Parser"
}

Code:

#include <Arduino.h>
#define LED D0   // Led in NodeMCU at pin GPIO16 (D0).
void setup() {
  pinMode(LED, OUTPUT);    // LED pin as output.
  digitalWrite(LED, LOW); // turn the LED on.
}

Defining port with static const uint8_t D0 = 16; creates the following error:

mpu6050MicrosOutput:2:22: error: redefinition of 'const uint8_t D0'
 static const uint8_t D0 = 16;
                      ^

 static const uint8_t D0   = 16;
                      ^

Using "C_Cpp.intelliSenseEngine": "Tag Parser" turns off IDE errors, Although, makes development vulnerable to mistakes. Any solutions?

[edolis]

have a look at my issue, to see if my fix works for you too #1178

Thanks @edolis , as #1178 it works by force including pins_Arduino.h to c_cpp_properties.json
