USB Host 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.

Repository content

This repository provides the STM32Cube USB Host Middleware Library, common to every STM32Cube MCU firmware that supports it.

This represents STMicroelectronics’ offering to support the USB Host role on STM32 MCUs. It includes two main modules:

• Core: provides USB host standard peripheral control APIs implementing the USB 2.0 standard code for a USB host. These APIs are called in every USB Host application, regardless of the desired functionality.

• Class: provides APIs for commonly supported USB host classes complying with USB 2.0 standard and their respective class specifications. These APIs are called in USB Host applications based on the desired functionality.

Release note

Details about the content of this release are available in the release note here.

Compatibility information

Please refer to the release note in the firmware repository for the STM32 series you are using (list). 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.
