Just installed PlatformIO and created a new project,I am trying to compile my original src code however I am getting a “Failed Status”.
Please let me know what should I do.

 *  Executing task: platformio run --environment megaatmega2560

Hi @guzunn !

Please show content of the platformio.ini and let us know which board exactly do you use.

Dear Sivar,

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:megaatmega2560]
platform = atmelavr
board = megaatmega2560
framework = arduino

Please see attached the content below:

I think something went wrong while installing the platform.

• Close VS-Code
• Delete the folders packages and platforms located in /Users/cezarguzun/.platformio/
• Restart VS Code
• Wait until PlatformIO finished installing the necessary files
• The red squiggles under #include <Arduino.h> should disappear and the project should compile without issues.
