STM32CubeU0

概要

STM32Cube is an STMicroelectronics original initiative to make the life of the developer easier by reducing development effort, time, and cost. STM32Cube covers the entire 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 STM32CubeU0 MCU Package, composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, a consistent set of middleware components, such as Azure^® RTOS, USB, and STM32 touch library. 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 drivers are production-ready and have been developed in compliance with V‑Model requirements for design, implementation, and tests. Furthermore, the STMicroelectronics-specific validation process adds a deeper qualification level, such as compliance with MISRA C^®:2012 guidelines, and elimination of possible runtime errors with the Synopsys® Coverity® static analysis tool. Reports are available on demand.

STM32CubeU0 gathers in one single package all generic embedded software components required to develop an application on STM32U0 series. Following the STM32Cube initiative, this set of components is highly portable, not only within the STM32U0 series, but also to other STM32 series. In addition, the low-layer APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeU0 HAL at the cost of portability and simplicity.

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