Description of STM32F7 HAL and Low-layer drivers

Introduction

STMCube

is STMicroelectronics's original initiative to ease developers' life by reducing development

efforts, time and cost. STM32Cube covers the STM32 portfolio.

STM32Cube Version 1.x includes:

The STM32CubeMX, a graphical software configuration tool that allows generating C initialization

code using graphical wizards.

A comprehensive embedded software platform, delivered per series (such as STM32CubeF7 for

STM32F7 Series)

The STM32Cube Hardware Abstraction Layer (HAL), an STM32 abstraction layer embedded

software, ensuring maximized portability across the STM32 portfolio

A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics

The Low Layer APIs (LL) offering a fast, light-weight, expert-oriented layer which is closer to

the hardware than the HAL. The LL APIs are available only for a set of peripherals.

All embedded software utilities coming with a full set of examples.

The HAL driver layer provides a generic multi-instance 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 family 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, to manage data transfers based on polling, to handle

interrupts or DMA, and to 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: basic timer, capture, pulse width modulation

(PWM), etc. 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, USB, SDMMC).

The HAL and LL 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.

The source code of HAL and LL drivers is developed in Strict ANSI-C which makes it independent from

the development tools. It is checked with CodeSonar™ static analysis tool. It is fully documented and is

MISRA-C 2004 compliant.
