platform

Type: String | Multiple: No

Development Platforms name.

PlatformIO allows one to use specific version of platform using Semantic Versioning (X.Y.Z=MAJOR.MINOR.PATCH) or VCS (Git, Mercurial and Subversion).

Version specifications can take any of the following forms:

  • 1.2.3: an exact version number. Use only this exact version

  • ^1.2.3: any compatible version (exact version for 1.x.x versions)

  • ~1.2.3: any version with the same major and minor versions, and an equal or greater patch version

  • >1.2.3: any version greater than 1.2.3. >=, <, and <= are also possible

  • >0.1.0,!=0.2.0,<0.3.0: any version greater than 0.1.0, not equal to 0.2.0 and less than 0.3.0

Other forms are the same as for the platformio platform install command.

Examples:

[env:the_latest_version]
platform = atmelavr

[env:exact_version]
platform = atmelavr@1.2.3

[env:specific_major_version]
platform = atmelavr@^1.2.3

[env:specific_major_and_minor_version]
platform = atmelavr@~1.2.3

[env:development_verion_by_git]
platform = https://github.com/platformio/platform-ststm32.git

[env:custom_git_branch]
platform = https://github.com/platformio/platform-espressif8266.git#feature/stage

[env:specific_git_commit]
platform = https://github.com/platformio/platform-espressif8266.git#921855a9c530082efddb5d48b44c3f4be0e2dfa2

New in version 4.0.

Type: String | Multiple: Yes

Configure custom packages per a build environment. You can also override default packages by Development Platforms using the same name. Packages will be installed in packages_dir.

Examples:

[env:override_default_toolchain]
platform = atmelavr
platform_packages =
  ; use GCC AVR 5.0+
  toolchain-gccarmnoneeabi@>1.50000.0

[env:override_framework]
platform = espressif8266
platform_packages =
  ; use upstream Git version
  framework-arduinoespressif8266 @ https://github.com/esp8266/Arduino.git

[env:external_package]
platform = ststm32
platform_packages =
  ; latest openOCD from PlatformIO Package Registry
  tool-openocd

  ; source code of ST-Link
  tool-stlink-source @ https://github.com/texane/stlink.git
