Description of STM32F1xx HAL drivers  
Introduction  
STMCubeTM is an STMicroelectronics original initiative to ease developers life by reducing development  
efforts, time and cost. STM32Cube covers 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 STM32CubeF1 for  
STM32F1 series)  
The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized  
portability across STM32 portfolio  
A consistent set of middleware components such as RTOS, USB, TCP/IP, Graphics  
All embedded software utilities coming with a full set of examples.  
The HAL drivers layer provides a generic multi instance simple set of APIs (application programming  
interfaces) to interact with the upper layer (application, libraries and stacks). It is composed of generic  
and extension APIs. It is directly built around a generic architecture and allows the built-upon layers,  
such as the middleware layer, to implement their functions without knowing in-depth how to use the  
MCU. This structure improves the library code reusability and guarantees an easy portability on other  
devices.  
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 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 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 drivers 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.  
The HAL drivers 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.  
This user manual is structured as follows:  
Overview of the HAL drivers  
Detailed description of each peripheral driver: configuration structures, functions, and  
how to use the given API to build your application.
