它在半双工通讯中，可以工作在主和从2种模式下。

当它作为主设备时，通过接口向外部的从设备提供时钟信号。

警告：由于SPI3/I2S3 的部分引脚与JTAG 引脚共享(SPI3_NSS/I2S3_WS 与JTDI ，SPI3_SCK/I2S3_CK与JTDO)，因此这些引脚不受IO控制器控制，他们(在每次复位后) 被默认保留为JTAG用途。

如果用户想把引脚配置给SPI3/I2S3，必须(在调试时)关闭JTAG并切换至SWD接口，或者(在标准应用时)同时关闭JTAG和SWD接口。

互联型产品是指STM32F105xx和STM32F107xx微控制器。

除非特别说明，本章描述的模块适用于整个STM32F10xxx微控制器系列。

SPI简介在大容量产品和互联型产品上，SPI接口可以配置为支持SPI协议或者支持I2S音频协议。

SPI接口默认工作在SPI方式，可以通过软件把功能从SPI模式切换到I2S模式。

在小容量和中容量产品上，不支持I2S音频协议。

串行外设接口（SPI）允许芯片与外部设备以半/全双工、同步、串行方式通信。

此接口可以被配置成主模式，并为外部从设备提供通信时钟（SCK）。

接口还能以多主配置方式工作。

它可用于多种用途，包括使用一条双向数据线的双线单工同步传输，还可使用CR破验的可靠通信。

I 2S也是一种3弓I脚的同步串行接口通讯协议。

它支持四种音频标准，包括飞利浦I2S标准，MSB和LSB对齐标准，以及PCM标准。

它在半双工通讯中，可以工作在主和从2种模式下。

当它作为主设备时，通过接口向外部的从设备提供时钟信号。

警告：由于SPI3/I2S3 的部分弓I脚与JTAG引脚共享（SPI3_NSS/I2S3_WS 与JTDI ,SPI3_SCK/I2S3_CK与JTDO）,因此这些引脚不受IO控制器控制，他们（在每次复位后）被默认保留为JTAG用途。

如果用户想把引脚配置给SPI3/I2S3，必须（在调试时）关闭JTAG并切换至SW或口，或者（在标准应用时）同时关闭JTAG和SWD接口。

下图是一个单主和单从设备互连的例子。
图210单主和单从应用
1.这里NSS引脚设置为输入
MOSI脚相互连接，MISO脚相互连接。这样，数据在主和从之间串行地传输(MSB位在前)。
通信总是由主设备发起。主设备通过MOSI脚把数据发送给从设备，从设备通过MISO引脚回传数据。这意味全双工通信的数据输出和数据输入是用同一个时钟信号同步的；时钟信号由主设备通过SCK脚提供。
读SPI_DR寄存器时，RXNE位被清除。
23.3.3配置SPI为主模式
在主配置时，在SCK脚产生串行时钟。
配置步骤
1.通过SPI_CR1寄存器的BR[2:0]位定义串行时钟波特率。
2.选择CPOL和CPHA位，定义数据传输和串行时钟间的相位关系(见图212)。
3.设置DFF位来定义8位或16位数据帧格式。
●支持DMA功能的1字节发送和接收缓冲器：产生发送和接受请求
23.2.2I2S功能
●单工通信(仅发送或接收)
●主或者从操作
●8位线性可编程预分频器，获得精确的音频采样频率(8KHz到96kHz)
●数据格式可以是16位，24位或者32位
●音频信道固定数据包帧为16位(16位数据帧)或32位(16、24或32位数据帧)
数据发送过程
在写操作中，数据字被并行地写入发送缓冲器。
当从设备收到时钟信号，并且在MOSI引脚上出现第一个数据位时，发送过程开始(译注：此时第一个位被发送出去)。余下的位(对于8位数据帧格式，还有7位；对于16位数据帧格式，还有15位)被装进移位寄存器。当发送缓冲器中的数据传输到移位寄存器时，SPI_SP寄存器的TXE标志被设置，如果设置了SPI_CR2寄存器的TXEIE位，将会产生中断。
请按照以下步骤配置SPI为从模式：

该函数库是一个固件函数包，它由程序、数据结构和宏组成，包括了微控制器所有外设的性能特征。

该函数库还包括每一个外设的驱动描述和应用实例。

通过使用本固件函数库，无需深入掌握细节，用户也可以轻松应用每一个外设。

因此，使用本固态函数库可以大大减少用户的程序编写时间，进而降低开发成本。

每个外设驱动都由一组函数组成，这组函数覆盖了该外设所有功能。

每个器件的开发都由一个通用API(application programming interface应用编程界面)驱动，API对该驱动程序的结构，函数和参数名称都进行了标准化。

所有的驱动源代码都符合“Strict ANSI-C”标准（项目于范例文件符合扩充ANSI-C标准）。

我们已经把驱动源代码文档化，他们同时兼容MISRA-C2004标准（根据需要，我们可以提供兼容矩阵）。

由于整个固态函数库按照“Strict ANSI-C”标准编写，它不受不同开发环境的影响。

仅对话启动文件取决于开发环境。

该固态函数库通过校验所有库函数的输入值来实现实时错误检测。

该动态校验提高了软件的鲁棒性。

实时检测适合于用户应用程序的开发和调试。

但这会增加了成本，可以在最终应用程序代码中移去，以优化代码大小和执行速度。

想要了解更多细节，请参阅Section2.5。

因为该固件库是通用的，并且包括了所有外设的功能，所以应用程序代码的大小和执行速度可能不是最优的。

对大多数应用程序来说，用户可以直接使用之，对于那些在代码大小和执行速度方面有严格要求的应用程序，该固件库驱动程序可以作为如何设置外设的一份参考资料，根据实际需求对其进行调整。

There are 12 new products peripherals direct data storage channel, there is a CRC calculation unit, like other STM32 microcontrollers, the supports 96 unique identifier.New series also has followed the STM32 microcontroller family of products low voltage and energy saving are two advantages. 2.0V to 3.6V operating voltage range compatible with the mainstream of battery technologies such as lithium batteries and nickel-metal hydride batteries, the package also features a battery operation mode dedicated pin Vbat. 72MHz frequency to execute code from flash consumes only 27mA current. There are four low-power mode, the current consumption can be reduced to two microamps. Quick Start from low power mode to save energy too; starting circuit using STM32 internally generated 8MHz signal, the microcontroller from stop mode when you wake up with less than 6 microseconds.中文翻译：单片机STM321 STM32的介绍STM32系列基于专为要求高性能、低成本、低功耗的嵌入式应用专门设计的ARM Cortex-M3内核。
