# USB Device Middleware Library MCU Software Component
|
||
|
||
|
||
|
||
## Overview of the STM32Cube MCU offer on GitHub
|
||
|
||
**STM32Cube** is an original initiative by STMicroelectronics to **simplify** prototyping and development by **reducing** effort, time, and cost. It supports the entire ARM™ Cortex-based STM32 microcontroller portfolio and provides a **comprehensive** software solution including:
|
||
* The CMSIS Core and Device interfaces enabling access to processor core features and device-specific peripherals of STM32 microcontrollers.
|
||
* The STM32 HAL-LL drivers, an abstraction layer offering a set of APIs ensuring maximized portability across the STM32 portfolio.
|
||
* The BSP drivers enabling access to peripherals on the STM32 development boards, external to the microcontroller itself.
|
||
* A consistent set of middleware 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, and provided with support for multiple IDEs.
|
||
|
||
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).
|
||
|
||
## Repository content
|
||
|
||
This repository provides the STM32Cube **USB Device** Middleware Library, **common to every** STM32Cube MCU firmware that supports it.
|
||
|
||
This represents STMicroelectronics’ offering to support the USB Device role on STM32 MCUs. It includes two main modules:
|
||
|
||
- **Core**: provides USB Device standard peripheral control APIs implementing the USB 2.0 standard code for a USB device. These APIs are called in every USB Device application, regardless of the desired functionality.
|
||
|
||
- **Class**: provides APIs for commonly supported USB Device classes complying with USB 2.0 standard and their respective class specifications. These APIs are called in USB Device applications based on the desired functionality.
|
||
|
||
## Release note
|
||
|
||
Details about the content of this release are available in the release note [here](https://htmlpreview.github.io/?https://github.com/STMicroelectronics/stm32-mw-usb-device/blob/master/Release_Notes.html).
|
||
|
||
## Compatibility information
|
||
|
||
Please refer to the **release note** in the firmware repository for the STM32 series you are using ([list](https://github.com/STMicroelectronics/STM32Cube_MCU_Overall_Offer/blob/master/README.md#stm32cube-mcu-packages)). It is **important** to use a **consistent set** of software component versions (i.e., CMSIS, HAL-LL, BSP, MW) as specified in the release note.
