STM32Cube MCU Package for STM32 L1 series (HAL, Low-Layer APIs and CMSIS (CORE, DSP, RTOS), USB, File system, RTOS, Touch Sensing, 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 covers the wholeSTM32 portfolio.

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

It also comprises the STM32CubeL1 platform composed of the STM32Cube HAL and the low-layer (LL) APIs, plus a consistent set of middleware components such as RTOS, USB, FatFS, Graphics and STM32 touch sensing. All embedded software is delivered with a full set of examples running on STMicroelectronics boards.

The STM32Cube HAL is an STM32 embedded software stack that ensures a 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® guidelines and ISO/TS 16949. On top of that, ST specific validation processes add a deeper-level qualification. 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 STM32CubeL4 HAL at the cost of portability and simplicity.

STM32CubeL1 is fully compatible with STM32CubeMX code generator that allows to generate initialization code. The package includes a low-level hardware abstraction layer (HAL) that covers the microcontroller hardware, together with an extensive set of examples running on STMicroelectronics boards. HAL and LL APIs are available in open-source BSD license for user convenience.
