Atom Text Editor Download Macdownzup

PlatformIO IDE is the next-generation integrated development environment for IoT.

Download Atom 1.54 for Windows for free, without any viruses, from Uptodown. Try the latest version of Atom 2021 for Windows. Atom is fast becoming my new favorite text editor. It handles Markdown beautifully, is great for HTML, runs faster than stink, and has great community support. Here’s how you install Atom and set it up as a full-featured Markdown editor: Note: I’m doing this all on a Mac. I’ve included Windows commands where relevant.

  • Cross-platform build system without external dependencies to the OS software:

    • 800+ Boards
    • 35+ Development Platforms
    • 20+ Frameworks
  • C/C++ Intelligent Code Completion

  • C/C++ Smart Code Linter for rapid professional development

  • Library Manager for the hundreds popular libraries

  • Multi-projects workflow with multiple panes

  • Themes support with dark and light colors

  • Serial Port Monitor

  • Built-in Terminal with PlatformIO Core (CLI) and CLI tool (pio, platformio)

  • Built-in PlatformIO Home.

Atom is a text editor that’s modern, approachable,yet hackable to the core—a tool you can customize to do anything but also useproductively without ever touching a config file.

Note

Please note that you do not need to install PlatformIO Core (CLI) separatelyif you are going to use PlatformIO IDE for Atom. PlatformIO Core (CLI) is built intoPlatformIO IDE and you will be able to use it within PlatformIO IDE Terminal.

Atom Text Editor Install

Also, PlatformIO IDE allows one to install PlatformIO Core (CLI) Shell Commands(pio, platformio) globally to your system viaMenu:PlatformIO>InstallShellCommands.

  1. Download and install GitHub’s official Atom text editor. PlatformIO IDE is built on top of it.
  2. Open Atom Package Manager
  • Mac OS X, Menu:Atom>Preferences>Install
  • Windows, Menu:File>Settings>Install
  • Linux, Menu:Edit>Preferences>Install
  1. Search for the official platformio-idepackage
  2. Install PlatformIO IDE.

PlatformIO IDE uses Clang for the Intelligent CodeCompletion. To check that clang is available in your system, pleaseopen Terminal and run clang--version. If clang is not installed,then install it and restart Atom:

  • Mac OS X: Install the latest Xcodealong with the latest Command Line Tools(they are installed automatically when you run clang in Terminal for thefirst time, or manually by running xcode-select--install

  • Windows: Download Clang 3.9.1 for Windows.Please select “Add LLVM to the system PATH” option on the installation step.

    Warning

    PLEASE DO NOT INSTALL CLANG 4.0. TEMPORARILY, WE SUPPORT ONLY CLANG 3.9.

    If you see a FailedtofindMSBuildtoolsetsdirectory error inthe installation console, please ignore it and press any key to closethis window. PlatformIO IDE uses only the Clang completion engine, whichshould work after that without any problems.

  • Linux: Using package managers: apt-getinstallclang or yuminstallclang.

  • Other Systems: Download the latest Clang for the other systems.

Warning

If some libraries are not visible in PlatformIO IDE for Atom and Code Completion orCode Linting does not work properly, please perform Menu:PlatformIO>RebuildC/C++ProjectIndex(Autocomplete,Linter)

This tutorial introduces you to the basics of PlatformIO IDE workflow and showsyou the creation process for a simple “Blink” example. After finishing, you willhave a general understanding of how to work with projects in the IDE.

After installation, launch PlatformIO IDE by opening Atom. Once Atom isopened, the PlatformIO IDE auto installer will continue to install dependent packagesand PlatformIO Core (CLI). Please be patient and let the installation complete. Once finished,PlatformIO IDE will ask you to reload the Atom window to applyinstalled components. Please click on ReloadNow. After that, PlatformIO IDE isready for use. Happy coding!

  1. Click on the “PlatformIO Home” button on the PlatformIO Toolbar
  1. Click on “New Project”, select a board and create a new PlatformIO Project
  1. Open the main.cpp file in the src folder and replace its contents withthe following:
Download

Warning

The code below only works with Arduino-based boards. Pleasevisit the PlatformIO Project Examples repository for other pre-configured projects.

PlatformIO IDE proposes different ways to process the project (build, clean,upload firmware, run other targets) using:

  • Building / Uploading / Targets and hotkeys
  1. Run Build and you should see a green “success” result in the buildpanel:

To upload firmware to the board, run Upload.

  1. What is more, you can run specific target or process project environmentusing Menu:PlatformIO>Runothertarget...or call targets list from the status bar (bottom, left corner):

And select desired target:

  1. To launch the built-in terminal interface, choose Menu:PlatformIO>Terminal orpress the corresponding icon in the PlatformIO toolbar:

This provides you fast access to a set of powerful PlatformIO Core (CLI) CLI commands:

  1. To run the built-in “Serial Monitor”, choose Menu:PlatformIO>SerialMonitoror press the corresponding icon in the PlatformIO toolbar:

The monitor has several settings to adjust your connection:

It also allows you to communicate with your board in an easy way:

platformio-ide package adds to Atomnew menu item named Menu:PlatformIO (after Menu:Help item).

PlatformIO IDE Toolbar contains quick access buttons for the popular commands.Each button contains a hint (leave the mouse on it for a moment).

  • PlatformIO: Build
  • PlatformIO: Upload
  • PlatformIO: Clean
  • Run other target (Build environments, Unit Testing)
  • Toggle build panel
  • Find in Project…
  • PlatformIO Terminal
  • Serial Monitor
  • Atom Settings
  • cmd-alt-b / ctrl-alt-b / f9 builds project without auto-uploading.
  • cmd-alt-u / ctrl-alt-u builds and uploads (if no errors).
  • cmd-alt-c / ctrl-alt-c cleans compiled objects.
  • cmd-alt-t / ctrl-alt-t / f7 run other targets (Upload using Programmer, Upload SPIFFS image, Update platforms and libraries).
  • cmd-alt-g / ctrl-alt-g / f4 cycles through causes of build error.
  • cmd-alt-h / ctrl-alt-h / shift-f4 goes to the first build error.
  • cmd-alt-v / ctrl-alt-v / f8 toggles the build panel.
  • escape terminates build / closes the build window.

More options: Menu:PlatformIO>Settings>Build.

PlatformIO IDE uses clang for the Intelligent Code Completion.To install it or check if it is already installed, please follow see the stepII. Clang for Intelligent Code Completion from Installation guide.

Warning

The libraries which are added/installed after the initializing process willnot be reflected in the code linter. You need Menu:PlatformIO>RebuildC/C++ProjectIndex(Autocomplete,Linter).

PlatformIO IDE uses PlatformIO’s pre-built GCC toolchains for Smart Code Linterand rapid professional development.The configuration data are located in .gcc-flags.json. This file will beautomatically created and preconfigured when you initialize project usingMenu:PlatformIO>InitializenewPlatformIOProjectorupdateexisting....

Warning

If some libraries are not visible in PlatformIO IDE for Atom and Code Completion orCode Linting does not work properly, please perform Menu:PlatformIO>RebuildC/C++ProjectIndex(Autocomplete,Linter)

Please navigate to PlatformIO Core Install Shell Commands.

Smart Code Linter is disabled by default for Arduino files(*.ino and .pde) because they are not valid C/C++ basedsource files:

  1. Missing includes such as #include<Arduino.h>
  2. Function declarations are omitted.

There are two solutions:

Recommended! See Convert Arduino file to C++ manually.

To force Smart Code Linter to use Arduino files as C++ please

  1. Open .gcc-flags.json file from the Initialized/Imported project and add-xc++ flag at the beginning of the value of gccDefaultCppFlags field:
  1. Perform all steps from Convert Arduino file to C++ manually(without renaming to .cpp).

Warning

Please do not modify other flags here. They will be removed on a next“Project Rebuild C/C++ Index” stage.Please use build_flags for “platformio.ini” (Project Configuration File) instead.

Please read this article Installing PlatformIO on Arch Linux.

PlatformIO IDE hides build panel on success by default. Nevertheless, you cankeep it visible all time. Please follow toMenu:PlatformIO>Settings>Build and set PanelVisibility toKeepVisible.

Key-bindings (toggle panel):

  • cmd+alt+v - Mac OS X
  • ctrl+alt+v - Windows/Linux

If you want automatically save all edited files when triggering a build, please follow toMenu:PlatformIO>Settings>Build and check Automaticallysaveonbuild.

Click on a function/include, press F3 and you will be taken directly tothe declaration for that function.

You need to install atom-beautifypackage and C/C++ Uncrustify Code Beautifier.

Here’s how to uninstall the PlatformIO IDE for multiple OS.
