STM32CubeWBA - STM32Cube MCU Package for STM32WBA series (HAL, Low-Layer APIs and CMSIS, File system, RTOS, BLE/802.15.4, Thread and Zigbee stacks - and examples running on ST boards)

STM32Cube is an STMicroelectronics original initiative to make the life of the developer easier by reducing development effort, time, and cost. STM32Cube covers the whole STM32 portfolio.

STM32Cube includes STM32CubeMX, a graphical software configuration tool that allows the generation of C initialization code using graphical wizards.

It also comprises the STM32CubeWBA MCU Package, composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, a consistent set of middleware components such as STMTouch™, STM32_WPAN (Bluetooth® 5.4 profiles and services), Azure® RTOS kernel, OpenBootloader, mbedTLS, TFM, MCUboot, and HCI connectivity services. All embedded software utilities are delivered with a full set of examples running on STMicroelectronics boards.

The STM32Cube HAL is an STM32 embedded software layer that ensures maximized portability across the STM32 portfolio, while the LL APIs make up a fast, light-weight, expert-oriented layer, which is closer to the hardware than the HAL. HAL and LL APIs can be used simultaneously with a few restrictions.

Both the HAL and LL APIs are production-ready and have been developed in compliance with CodeSonar®, MISRA C®:2012 guidelines and ISO/TS 16949. Furthermore, STMicroelectronics specific validation processes add a deeper-level qualification.

The STM32CubeWBA gathers in one single package all generic embedded software components required to develop an application on STM32WBA series microcontrollers. Following STM32Cube initiative, this set of components is highly portable, not only within the STM32WBA series, but also to other STM32 series. In addition, the low-layer APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeWBA HAL at the cost of portability and simplicity.

HAL and LL APIs are available in open-source BSD license for user convenience.
