Product overview
Description
STM32Cube is an STMicroelectronics original initiative to improve designer productivity significantly 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 STM32CubeL1 MCU Package composed of the STM32Cube hardware abstraction layer (HAL) and the LL APIs, plus a consistent set of middleware components (RTOS, USB, FAT file system, graphics and STM32 touch sensing). 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 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.
STM32CubeL1 gathers in one single package all the generic embedded software components required to develop an application on STM32L1 microcontrollers. Following STM32Cube initiative, this set of components is highly portable, not only within STM32L1 series but also to other STM32 series. In addition, the low-layer APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeL1 HAL at the cost of portability and simplicity.
HAL and LL APIs are available under open-source BSD license for user convenience.
