1 Description
STM32Cube
™
is an STMicroelectronics original initiative to improve developers' productivity 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 STM32CubeG0 MCU Package composed of the STM32Cube
™
hardware abstraction layer
(HAL) and the low-layer (LL) APIs, plus a consistent set of middleware components (RTOS, USB, FAT file system
and UCPD power delivery).
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 MISRA-C
®
:2012
guidelines with some documented exceptions (reports available on demand) and ISO/TS 16949. Furthermore,
ST-specific validation processes add a deeper-level qualification.
The STM32CubeG0 gathers in one single package all the generic embedded software components required to
develop an application on STM32G0 microcontrollers. Following STM32Cube
™
initiative, this set of components
is highly portable, not only within the STM32G0 Series but also to other STM32 Series. In addition, the low-layer
APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeG0 HAL at the cost of
portability and simplicity.
HAL and LL APIs are available in open-source BSD license for user convenience.
