STM32Cube MCU Package for STM32L4 series and STM32L4 Plus series (HAL, Low-Layer APIs and CMSIS (CORE, DSP, RTOS), USB, TouchSensing, File system, RTOS, Graphic - coming with examples running on ST boards: STM32 Nucleo, Discovery kits and Evaluation boards)

STMCube is an STMicroelectronics original initiative to make developers' lives easier by reducing development effort, time and cost. STM32Cube is the implementation of STMCube that 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 STM32CubeL4 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, 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 APIs are production-ready and have been developed in compliance with MISRA C®:2004 guidelines with some documented exceptions (reports available on demand) and ISO/TS 16949. Furthermore, ST-specific validation processes add a deeper-level qualification.

STM32CubeL4 gathers in one single package all the generic embedded software components required to develop an application on STM32L4 or STM32L4+ microcontrollers. Following STM32Cube initiative, this set of components is highly portable, not only within STM32L4 Series and STM32L4+ Series but also to other STM32 Series. In addition, the low-layer APIs provide an alternative, high-performance, low-footprint solution to the STM32CubeL4 HAL at the cost of portability and simplicity.

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