Description of STM32F3 HAL and low-layer drivers  
Introduction  
STMCubeTM is an STMicroelectronics original initiative to make developers' lives easier by reducing  
development effort, time and cost. STM32Cube covers the whole STM32 portfolio.  
STM32Cube Version 1.x includes:  
STM32CubeMX, a graphical software configuration tool that allows the generation of C initialization  
code using graphical wizards.  
A comprehensive embedded software platform, delivered per Series (such as STM32CubeF3 for  
STM32F3 Series).  
The STM32Cube HAL, STM32 abstraction layer embedded software ensuring maximized  
portability across the STM32 portfolio  
Low-layer APIs (LL) offering a fast light-weight expert-oriented layer which is closer to the  
hardware than the HAL. LL APIs are available only for a set of peripherals.  
A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics  
All embedded software utilities, delivered with a full set of examples.  
The HAL driver layer provides a generic multiinstance simple set of APIs (application programming  
interfaces) to interact with the upper layer (application, libraries and stacks).  
The HAL driver APIs are split into two categories: generic APIs which provide common and generic  
functions for all the STM32 series, and extension APIs which include specific and customized functions  
for a given line or part number. The HAL drivers include a complete set of ready-to-use APIs which  
simplify the user application implementation. As an example, the communication peripherals contain  
APIs to initialize and configure the peripheral, manage data transfers in polling mode, handle interrupts  
or DMA, and manage communication errors.  
The HAL drivers are feature-oriented instead of IP-oriented. As an example, the timer APIs are split into  
several categories following the functions offered by the IP such as basic timer, capture, or pulse width  
modulation (PWM). The HAL driver layer implements run-time failure detection by checking the input  
values of all functions. Such dynamic checking contributes to enhance the firmware robustness. Run-  
time detection is also suitable for user application development and debugging.  
The LL drivers offer hardware services based on the available features of the STM32 peripherals. These  
services reflect exactly the hardware capabilities and provide atomic operations that must be called  
following the programming model described in the product line reference manual. As a result, the LL  
services are not based on standalone processes and do not require any additional memory resources to  
save their states, counter or data pointers: all operations are performed by changing the associated  
peripheral registers content. Contrary to the HAL, the LL APIs are not provided for peripherals for which  
optimized access is not a key feature, or for those requiring heavy software configuration and/or  
complex upper level stack (such as FSMC or USB).  
The HAL and LL drivers are complementary and cover a wide range of applications requirements:  
The HAL offers high-level and feature-oriented APIs, with a high-portability level. They hide the  
MCU and peripheral complexity to end-user.  
The LL offers low-level APIs at registers level, with better optimization but less portability. They  
require deep knowledge of the MCU and peripherals specifications.  
HAL and LL source code is developed in Strict ANSI-C which makes it independent from the  
development tools. It is checked with CodeSonarTM static analysis tool. It is fully documented and is  
MISRA-C 2004 compliant.
