**STM32Cube** is an STMicroelectronics original initiative to easethedevelopers life by reducing efforts, time and cost.

**STM32Cube**covers the overall STM32 products portfolio. It includes a comprehensive embedded software platform, delivered for eachSTM32series.

* The CMSISmodules (coreanddevice) corresponding to the ARM(tm)coreimplemented in thisSTM32product

* The STM32 HAL-LL drivers :an abstractiondriverslayer, the APIensuring maximized portability across the STM32 portfolio

* The BSPDrivers of each evaluation or demonstration board provided by this STM32 series

* A consistent set ofmiddlewares componentssuch asRTOS,USB,FatFS, Graphics, STM32_TouchSensing_Library ...

* A full set of software projects (basic examples, applications or demonstrations)for each boardprovidedby this STM32 series

**STM32Cube**is an original initiative by STMicroelectronics to**simplify** prototyping and development by**reducing** effort, time, and cost. It supports the entire ARM™ Cortex-basedSTM32microcontroller portfolio and provides a**comprehensive** software solution including:

* The CMSISCoreandDevice interfaces enabling access to processorcorefeatures and device-specific peripherals ofSTM32microcontrollers.

* The STM32 HAL-LL drivers,an abstraction layer offering a set of APIsensuring maximized portability across the STM32 portfolio.

* The BSPdrivers enabling access to peripherals on the STM32 development boards, external to the microcontroller itself.

* A consistent set ofmiddleware libraries offering standardized, high-level functionalities —such as USB,TCP/IP, file systems, and graphics.

* A full set of software projects (basic examples, applications, and demonstrations)that showcase specific functionalities or use cases, andprovidedwith support for multiple IDEs.

Two models of publication are proposed for the STM32Cube embedded software :

* The monolithic**MCU Package** : all STM32Cube software modules of one STM32 series are present (Drivers, Middlewares, Projects, Utilities) in the repo (usual name**STM32Cubexx**, xx corresponding to the STM32 series)

* The**MCU component** : progressively from November 2019, each STM32Cube software module being part of the STM32Cube MCU Package, will be delivered as an individual repo, allowing the user to select and get only the required software functions.

The**STM32Cube embedded software** is available in two flavors:

* The**MCU Firmware**_monolithic_ offer, where**all** software components (Drivers, Middleware, Projects, Utilities) are included in a**single** repository for each STM32 series.

* The**MCU Software Components**_modular_ offer, where**each** software component (mainly Drivers and Middleware) is provided in a**dedicated** repository, allowing users to**select** only the components they need.

The complete list of repositories is available[here](https://github.com/STMicroelectronics/STM32Cube_MCU_Overall_Offer/blob/master/README.md#content).

This**cmsis_device_wl** MCU component repo is one element of the STM32CubeWL MCU embedded software package, providing the**cmsis device** part.

Details about the content of this release are available in the release note[here](https://htmlpreview.github.io/?https://github.com/STMicroelectronics/cmsis_device_wl/blob/master/Release_Notes.html).

Details about the content of this release are available in the release note[here](https://htmlpreview.github.io/?https://github.com/STMicroelectronics/cmsis-device-wl/blob/main/Release_Notes.html).

It is**crucial** that you use a consistent set of versions for the CMSIS Core - CMSIS Device, as mentioned in[this](https://htmlpreview.github.io/?https://github.com/STMicroelectronics/STM32CubeWL/blob/main/Release_Notes.html) release note.

The full**STM32CubeWL** MCU package is available[here](https://github.com/STMicroelectronics/STM32CubeWL).

If you have any issue with the**Software content** of this repo, you can[file an issue on Github](https://github.com/STMicroelectronics/cmsis_device_wl/issues/new).
