STM32Cube MCU Overall Offer


STM32Cube is an STMicroelectronics original initiative to ease the developers life by reducing efforts, time and cost.

STM32Cube covers the overall STM32 products portfolio (MCU and MPU). It includes a comprehensive embedded software platform, delivered for each STM32 series.

  • The CMSIS modules (core and device) corresponding to the ARM(tm) core implemented in this STM32 product.
  • The STM32 HAL-LL drivers, an abstraction layer offering a set of APIs ensuring maximized portability across the STM32 portfolio.
  • The BSP drivers of each evaluation, demonstration, or nucleo board provided for this STM32 series.
  • A consistent set of middleware libraries such as RTOS, USB, FatFS, graphics, touch sensing library...
  • A full set of software projects (basic examples, applications, and demonstrations) for each board provided for this STM32 series.

GitHub is a new publication model for the STM32Cube MCU embedded software. Different models of publication are proposed:

  • The MCU Package: A unique repo per STM32 MCU series containing the different components of a STM32 MCU firmware (Drivers, Middleware, Utilities, Examples). Please refer to the STM32Cube MCU Packages chapter below.
  • The MCU components: Each component of a STM32 MCU firmware (Drivers, Middleware, Utilities) is proposed in a dedicated repo, allowing the user to select and get only the required ones. Please refer to the STM32Cube MCU Components chapter below.
  • The X-CUBE: Expansion software proposing examples and applications that complement the ones of the STM32Cube firmware.
  • A set of MCU Utilities: Various utility features proposed in dedicated repos.

Please note that a MPU offer is also proposed for the STM32 MPU Products. You can refer to the repo STM32MPU_EmbSW_Overall_Offer.


This repo is a simple Readme describing all STM32 MCU related GitHub projects, the overall offer for the STM32 MCU products.

This new publication channel of the STM32Cube embedded software components will provide new added values:

  • In complement to the MCU Package zip files today proposed on, the capability for STM32 customers to get a configuration management based delivery (Git)
  • A more direct communication between developers, thanks to the Issues features. Caution: only software related questions will be taken into account. Any other subject must be submitted to the ST Community forum
  • Thanks to the deployment of a Contributor License Agreement feature (please refer to each repo CONTRIBUTING guide), the Pull-Request permits also to take into account customers proposed updates and enrich the STM32Cube FW offer.

For general communication and support, you can use

STM32Cube HAL Drivers

The HAL Drivers MCU Components propose the HAL and LL Drivers modules controlling all the HW IPs embedded in the STM32 products.

  • HAL Drivers:

    • A set of portable abstraction APIs offering high level services, built around standalone processes. The HAL drivers are functionalities oriented, example: for the Timer peripheral, the APIs could be split into several categories following the functions offered by the IPs (Basic timer, capture, PWM...) for a communication IP: an initialisation function, eventually a configuration function and data transfer services (polling, interruption or DMA based)
    • The compatibility SHALL be guaranteed across all the STM32 families for the generic APIs, including generic macros and common structures defines. Any specific feature is given in a dedicated extension model available in the associated extension files
  • LL Drivers:

    • Low Layer Drivers: a set of basic functions with direct hardware access (no standalone process), this layer can be called either by applications or by the HAL drivers.

HAL and LL Drivers are provided in the same module/repo

The dynamic usage of HAL APIs is provided thru projects examples, available in the respective STM32Cube MCU Packages STM32Cubexx where xx correspond to the series

STM32Cube BSP Drivers

The BSP Drivers MCU Components propose the BSP Drivers modules, which are constituted from the:

  • STM32Cube BSP Boards Drivers, based on the HAL drivers, and providing a set of high level APIs allowing a quick access to the boards services (e.g., audio, graphics, access to external memories).
  • STM32Cube BSP Components Drivers providing a set of high level APIs allowing a quick access to the (e.g., audio codecs, LCD drivers, SD cards, MEMS). The link between these external components and the HAL drivers (e.g., a SD card and the OSPI/QSPI HAL driver) is done within the BSP Boards drivers.

NOTE: A number of BSP components drivers (particularly of MEMS) come in two forms, each addressing a different purpose. For each one of such BSP components drivers, two repositories are available as explained below:

  • PID: Platform-Independent Drivers. Recognizable to their repositories' names <bspcomp> (e.g., hts221). Are low-level drivers allowing direct access to components' registers. These drivers are independent of any software platform, as the acronym PID suggests. The complete list can be found here.

  • STM32: STM32Cube-compatible drivers. Recognizable to their repositories' names stm32-<bspcomp> (e.g., stm32-hts221). Are hardware-abstracted drivers, specially designed to be compatible with the STM32Cube software offer, as the stm32- prefix suggests. The complete list is provided below (refer particularly to tables MEMS and Temperature Sensor).

STM32Cube Middleware Libraries

The Middleware Libraries MCU Components propose the following set of stacks common to all STM32xx series very useful to design number of middleware-based user applications.

These Middleware Libraries delivered in standalone mode, permit to get in advance, compared to the full FW Packages, the new features or updates. Please take a look to the Release Note to verify the compatibility information.

  • FatFS library: A set of platform- and storage device-independent services allowing user application to access storage devices and manage files.

  • FreeRTOS library: A set of platform-independent services implementing a real-time operating system kernel for embedded devices and providing methods for multiple threads or tasks, mutexes, semaphores and software timers.

  • LwIP library: LwIP (Lightweight IP) is an open-source TCP/IP stack designed to reduce resource usage while still offering a full-scale TCP stack. Among other services, it also offers a network interface, buffers and a memory management section, and an operating system emulation layer.

  • USB Device library: A set of services allowing the configuration and the control of the USB on STM32 MCUs in device mode. It is mainly based on the "Core" and the "Class" modules including the common and most used features and APIs.

  • USB Host library: A set of services allowing the configuration and the control of the USB on STM32 MCUs in host mode. It is mainly based on the "Core" and the "Class" modules including the common and most used features and APIs.

  • Open Bootloader library: An In-Application programming (IAP) utility based on the HAL-LL drivers and providing a set of services in order to perform all possible Bootloader operations. It is provided as an example that can be tailored and customized.

The dynamic usage of Middleware Libraries is provided thru projects examples, available in the respective STM32Cube MCU Packages STM32Cubexx where xx correspond to the series. Additionnal projects examples are also available under stm32u5-classic-coremw-apps.
