Mbed

Configuration:framework = mbed

Arm Mbed OS is an open source embedded operating system designed specifically for the ‘things’ in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices

For more detailed information please visit vendor site.

Configuration system

Warning

In Mbed OS 6 the list of supported boards was heavily reduced, only officially supported and well maintained targets left. More information in the official explanation. In order to keep legacy projects built on top of Mbed OS 5 compilable, each development platform contains a list of deprecated boards that is used to dynamically select the proper version of Mbed OS (OS5 or OS6).

PlatformIO allows you to customize mbed OS compile time configuration parameters using mbed_app.json manifest. It should be placed into the root of your project and located on the same level as “platformio.ini” (Project Configuration File).

Configuration is defined using JSON. Some examples of configuration parameters:

  • The sampling period for a data acquisition application.
  • The default stack size for a newly created OS thread.
  • The receive buffer size of a serial communication library.
  • The flash and RAM memory size of a target board.

See more details in the official ARM Mbed OS Configuration System.

A few PlatformIO-ready projects based on ARM mbed OS which use mbed_app.json:

Warning

On Windows the maximum length for a path (file name and directory route, also known as MAX_PATH) — has been defined by 260 characters which can lead to compilation error for some targets. It’s possible to shorten these paths is to install packages in root of any logical disk by specifying core_dir.

Mbed OS 6

Using Bare Metal profile

The bare metal profile implements a subset of Mbed OS’s RTOS APIs that are useful in non-threaded applications, such as semaphores (calling the release API from interrupts) and tickers (to set up a recurring interrupt). It does not include an RTX, and is therefore suitable for applications that do not require complex thread management. Instead of the RTOS’s scheduler, all activities are polled or interrupt-driven.

Mbed OS 5 and Mbed 2

PlatformIO allows compiling projects with or without Mbed OS 5. By default, project is built without the OS feature. Most of the framework functionality requires the OS to be enabled. To add the OS feature you can use a special macro definition that needs be added to build_flags of “platformio.ini” (Project Configuration File):

Name Description
PIO_FRAMEWORK_MBED_RTOS_PRESENT Build the project with enabled rtos

An example of “platformio.ini” (Project Configuration File) with enabled rtos

[env:wizwiki_w7500p]
platform = wiznet7500
framework = mbed
board = wizwiki_w7500p
build_flags = -D PIO_FRAMEWORK_MBED_RTOS_PRESENT

Build profiles

By default, PlatformIO builds your project using develop profile which provides optimized firmware size with full error information and allows MCU to go to sleep mode. In the case when default build profile is not suitable for your project there two other profiles release and debug that can be enabled using special macro definitions. You can change build profile build_flags of “platformio.ini” (Project Configuration File):

Name Description
MBED_BUILD_PROFILE_RELEASE Release profile (smallest firmware, minimal error info)
MBED_BUILD_PROFILE_DEBUG Debug profile (largest firmware, disabled sleep mode)

More information about differences between build profiles can be found on the official page ARM Mbed OS Build Profiles.

Ignoring particular components

In case you don’t need all parts of the framework or you want to reduce the compilation time, you can explicitly exclude folders with redundant sources. For example, to remove cellular, mbedtls and nanostack features from the build process, navigate to packages_dir and create a new file framework-mbed/features/.mbedignore with the following contents:

cellular/*
mbedtls/*
nanostack/*

If you want to exclude the entire folder, simply create .mbedignore file and add only one symbol * to this file.

Custom Targets

In case when your board is not officially supported by Mbed you can manually add custom board definitions to your project. First of all, you need to create a special file custom_targets.json in the root folder of your project where you describe your board, for example here is the configuration for NUCLEO-F401RE board:

{
  "NUCLEO_F401RE": {
    "inherits": [
        "MCU_STM32"
    ],
    "supported_form_factors": [
        "ARDUINO",
        "MORPHO"
    ],
    "core": "Cortex-M4F",
    "extra_labels_add": [
        "STM32F4",
        "STM32F401xE"
    ],
    "macros_add": [
        "STM32F401xE"
    ],
    "config": {
        "clock_source": {
            "help": "Mask value : USE_PLL_HSE_EXTC | USE_PLL_HSE_XTAL (need HW patch) | USE_PLL_HSI",
            "value": "USE_PLL_HSE_EXTC|USE_PLL_HSI",
            "macro_name": "CLOCK_SOURCE"
        }
    },
    "detect_code": [
        "0720"
    ],
    "device_has_add": [
        "SERIAL_ASYNCH",
        "FLASH",
        "MPU"
    ],
    "device_name": "STM32F401RE"
  }
}

Secondly, you need to add code specific to your target to the src folder of your project. Usually, it’s a good idea to isolate this code in a separate folder and add the path to this folder to build_flags of “platformio.ini” (Project Configuration File):

[env:my_custom_board]
platform = nxplpc
framework = mbed
board = my_custom_board
build_flags = -I$PROJECT_SRC_DIR/MY_CUSTOM_BOARD_TARGET

Next, you need to inform PlatformIO that there is a new custom board. To do this, you can create boards directory in the root folder of your project and add a board manifest file with your board name, e.g. my_custom_board.json as described here Custom Embedded Boards

After these steps, your project structure should look like this:

project_dir
├── include
├── boards
│    └── my_custom_board.json
├── src
│    ├── main.cpp
│    └── MY_CUSTOM_BOARD_TARGET
│         ├── pinNames.h
│         └── pinNames.c
├── custom_targets.json
└── platformio.ini
More information about adding custom targets can be found on the official page
Adding and configuring targets.
