Description

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

Classic CoreMW is a collection of middleware stacks and associated applications allowing RTOS management, File System operations and connectivity through USB. It is based on:

  • ST's proprietary stacks: ST USB Device and ST USB Host
  • Third parties' stacks: FatFS

This package is exclusively published on GitHub (and is neither available in STM32CubeMX nor STM32CubeIDE available on www.st.com). It contains the integration of the Classic CoreMW stacks with STM32WBA devices, allowing users to get quick access to pre-built projects integrating them.

Note

  • The repository containing this package has been created using the git submodule command. Please refer to the "How to use" section explaining how to clone this repository and how to get the latest updates.

Release note

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

List of applications

The STM32WBA Classic CoreMW package contains the following applications:

MiddlewareApplicationShort Description
FatFsFatFs_RAMDISK_StandaloneShows a typical application where the STM32 MCU write and read back a Fat Format text file from RAMDISK
ST USB DeviceHID_StandaloneShows a typical application where the STM32 MCU is enumerated as a HID device
ST USB DeviceCDC_StandaloneShows a typical application where the STM32 MCU is enumerated as a CDC device
ST USB HostHID_StandaloneShows how to use USB host application based on the Human Interface Class (HID) to connect a mouse or a keyboard
ST USB HostCDC_StandaloneShows how to use USB host application based on the Communication Device Class (CDC) to communicate with a usb flash disk

Note

  • FreeRTOS Middleware and examples are delivered on STM32WBA in the form of X-CUBE-FREERTOS that is available from st.com, from GitHub and from STM32CubeMX.
  • Projects in this package have not been generated with STM32CubeMX (i.e., no .ioc files are delivered).

Boards available

How to use

This repository intrinsically contains the applications (projects and source files) located under folder ./Projects. It also contains the CMSIS Core files under folder ./Drivers/CMSIS/Include for size optimization reason. Other dependencies such as the HAL and BSP drivers, or the middleware libraries themselves are linked using the git submodule command. Please check the instructions below for a proper use.

Note

  • To clone this repository along with the linked submodules, option --recursive has to be specified as shown below.
git clone --recursive https://github.com/STMicroelectronics/stm32wba-classic-coremw-apps
  • To get the latest updates, issue the following two commands (with the repository stm32u5-classic-coremw-apps as the current working directory).
git pull
git submodule update --init --recursive

Note

  • If GitHub "Download ZIP" option is used instead of the git clone command, then the required components have to be collected manually by the user.

Known Limitations

  • None

Troubleshooting

Please refer to the CONTRIBUTING.md guide.
