STM32微控制器是由意法半导体（STMicroelectronics）开发的一系列32位ARM Cortex-M微控制器产品线。在这些产品线中，外设开发库函数手册是开发者们编写程序时不可或缺的资源，它提供了丰富的API来简化硬件抽象层（HAL）的编程，使得开发者能够更高效地开发各种应用程序。文档标题所提及的“STM32外设开发库函数手册”通常指的是针对STM32系列微控制器的固件库（ Firmware Library），它是对硬件寄存器操作的高级封装，提供了一系列函数，供开发者在开发软件时调用。这些库函数主要包括： 1. 标准外设库（Standard Peripheral Library）：提供了一系列函数，用于访问STM32的外设功能。这些函数通过一套共同的API来标准化驱动结构、函数及其参数名称，实现了代码的高度可重用性。 2. 硬件寄存器地址映射：手册中会提供完整的寄存器地址映射，包括所有位、位字段和寄存器的声明，全部用C语言编写。这样做的好处是避免了繁琐的任务，并提供了一个无bug的参考映射文件，加快了项目的初期阶段。 3. 驱动函数与数据结构集合：涵盖了所有外设功能的例程和数据结构，可以直接用作参考框架。它还包含了支持核心相关内置功能的宏、通用常量和数据类型的定义。 4. 示例代码：提供了所有可用外设的示例代码，包括模板项目，供最常用的开发工具使用。配合硬件评估板，可以在几个小时内开始使用全新的微控制器进行开发。 5. 严格的ANSI C标准：库的开发遵循“Strict ANSI-C”标准（对于项目和示例文件使用relaxed ANSI-C），保证了与开发工具的独立性。仅有启动文件依赖于特定的开发工具。 6. MISRA-C2004合规性：STM32的外设开发库严格遵守MISRA-C 2004编程规范，这是业界公认的嵌入式C语言编程标准。 7. 运行时错误检测：库函数实现了运行时故障检测功能，通过检查所有库函数的输入值来增强软件的健壮性。这对于用户应用程序的开发和调试非常合适。 STM32系列微控制器支持的外设非常广泛，手册中会对各种外设的使用进行详细介绍，并且会为每个功能提供相应的库函数。例如，对于定时器（Timer）、通用输入输出（GPIO）、串行外设接口（SPI）、通用同步/异步收发器（USART）等，开发者都能找到相应的函数和设置步骤。这些库函数大大简化了编程工作，使得开发者不需要深入理解底层硬件就可以控制外设工作。此外，STM32固件库是基于模块化设计的，使得开发者能够轻松地根据需要启用或禁用特定的模块。这种结构使得代码易于在不同的STM32微控制器之间迁移，并且能够快速地将产品线扩展到市场上，无需重新设计。由于库函数已经高度优化，开发者可以专注于应用层的设计，而不需要担心硬件层面的细节。

Description of STM32F30xx/31xx Standard Peripheral Library

Introduction

The STM32F30xx and STM32F31xx Standard Peripheral Library covers 3 abstraction levels, and

includes:

 A complete register address mapping with all bits, bitfields and registers declared in C. This avoids

a cumbersome task and more important, it brings the benefits of a bug free reference mapping file,

speeding up the early project phase.

 A collection of routines and data structures covering all peripheral functions (drivers with common

API). It can directly be used as a reference framework, since it also includes macros for supporting

core-related intrinsic features, common constants, and definition of data types.

 A set of examples covering all available peripherals with template projects for the most common

development tools. With the appropriate hardware evaluation board, this allows to get started with

a brand-new micro within few hours.󳘪

Each driver consists of a set of functions covering all peripheral features. The development of each

driver is driven by a common API (application programming interface) which standardizes the driver

structure, the functions and the parameter names.The driver source code is developed in „Strict ANSI-C‟

(relaxed ANSI-C for projects and example files). It is fully documented and is MISRA-C 2004 compliant.

Writing the whole library in „Strict ANSI-C‟ makes it independent from the development tools. Only the

start-up files depend on the development tools. Thanks to the Standard Peripheral Library, low-level

implementation details are transparent so that reusing code on a different MCU requires only to

reconfigure the compiler. As a result, developers can easily migrate designs across the STM32 series to

quickly bring product line extensions to market without any redesign. In addition, the library is built

around a modular architecture that makes it easy to tailor and run it on the same MCU using hardware

platforms different from ST evaluation boards.

The Standard Peripheral Library implements run-time failure detection by checking the input values for

all library functions. Such dynamic checking contributes towards enhancing the robustness of the

software. Run-time detection is suitable for user application development and debugging. It adds an

overhead which can be removed from the final application code to minimize code size and execution

speed. For more details refer to Section 1.1.5: "Run-time checking".󳘪

Since the Standard Peripheral Library is generic and covers all peripheral features, the size and/or

execution speed of the application code may not be optimized. For many applications, the library may

be used as is. 󳘪

The firmware library user manual is structured as follows:

 Document conventions, rules, architecture and overview of the Library package.

 How to use and customize the Library (step by step).

 Detailed description of each peripheral driver: configuration structure, functions and how to use the

provided API to build your application.󳘪

The STM32F30xx and STM32F31xx Standard Peripheral Library will be referred to as STM32F30xx

Library throughout the document, unless otherwise specified.
