STM32CubeL1 HAL Driver MCU Component

latest tag


STM32Cube is an STMicroelectronics original initiative to ease developers' life by reducing efforts, time and cost.

STM32Cube covers the overall STM32 products portfolio. It includes a comprehensive embedded software platform delivered for each STM32 series.

  • The CMSIS modules (core and device) corresponding to the ARM(tm) core implemented in this STM32 product.
  • The STM32 HAL-LL drivers, an abstraction layer offering a set of APIs ensuring maximized portability across the STM32 portfolio.
  • The BSP drivers of each evaluation, demonstration or nucleo board provided for this STM32 series.
  • A consistent set of middleware libraries such as RTOS, USB, FatFS, graphics, touch sensing library...
  • A full set of software projects (basic examples, applications, and demonstrations) for each board provided for this STM32 series.

Two models of publication are proposed for the STM32Cube embedded software:

  • The monolithic MCU Package: all STM32Cube software modules of one STM32 series are present (Drivers, Middleware, Projects, Utilities) in the repository (usual name STM32Cubexx, xx corresponding to the STM32 series).
  • The MCU component: each STM32Cube software module being part of the STM32Cube MCU Package, is delivered as an individual repository, allowing the user to select and get only the required software functions.


This stm32l1xx_hal_driver MCU component repo is one element of the STM32CubeL1 MCU embedded software package, providing the HAL-LL Drivers part.
