To illustrate these points Figure I shows a typical surface sensor installation. The sensor in this case is mounted on a pipe which is carrying a fluid. The point closest to the fluid where a sensor can be mounted practically is the outer wall of the pipe. If the fluid flow is adequate and the temperature fluctuations are not severe, the outer wall temperature will be very close to that of the fluid.

进入停止模式
关于如何进入停止模式，详见表 3-4。 在停止模式下，通过设置电源控制寄存器(PWR_CR)的 LPDS 位使内部调节器进入低功耗 模式，能够降低更多的功耗。
如果正在进行 Flash 编程，直到对内存访问完成，系统才进入停止模式。 如果正在进行对 APB 的访问，直到对 APB 访问完成，系统才进入停止模式。 可以通过对独立的控制位进行编程，可选择以下功能：
表3-4 停止模式
进入
退出 唤醒延时
在以下条件下执行WFI或WFE指令： – 设置Cortex-M3系统控制寄存器中的SLEEPDEEP位 – 清除电源控制寄存器（PWR_CR）中的PDDS位 – 通过设置PWR_CR中LPDS位选择电压调节器的模式 注：为了进入停止模式，所有的外部中断的请求位(挂起寄存器(EXTI_PR))和RTC的闹 钟标志都必须被清除，否则停止模式的进入流程将会被跳过，程序继续运行。

3.1 电源
STM32 的工作电压(VDD)为 2.0～3.6V。通过内置的电压调节器提供所需的 1.8V 电源。 当主电源 VDD 掉电后，通过 VBAT 脚为实时时钟(RTC)和备份寄存器提供电源。
3.1.1
图3-1 电源框图 独立的 A/D 转换器供电和参考电压
如果应用中没有使用外部电池，VBAT 必须连接到 VDD 引脚上。
注意：在 VDD 上升阶段(tRSTTEMPO)，VBAT 和 VDD 之间的电源开关仍会保持连接在 VBAT。当 VDD 快速上升且达 到稳定状态，当 VBAT 低于 VDD−0.6V 时，电流通过 VDD 和 VBAT 之间的二极管流入到 VBAT。关于 tRSTTEMPO 可参考数据手册中的相关部分。

UM0427 用户手册32 位基于ARM 微控制器STM32F101xx 与STM32F103xx固件函数库介绍本手册介绍了32 位基于ARM 微控制器STM32F101xx 与STM32F103xx 的固件函数库。

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-C 2004 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Section 2.5。

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。

此份固件库用户手册的整体架构如下：定义，文档约定和固态函数库规则。

STM32-参考⼿册-中⽂.pdf23 串⾏外设接⼝(SPI)⼩容量产品是指闪存存储器容量在16K ⾄32K 字节之间的STM32F101xx、STM32F102xx和STM32F103xx微控制器。

中容量产品是指闪存存储器容量在64K⾄128K字节之间的STM32F101xx、STM32F102xx和STM32F103xx微控制器。

⼤容量产品是指闪存存储器容量在256K⾄512K字节之间的STM32F101xx和STM32F103xx微控制器。

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。

23.1 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CRC校验的可靠通信。

I2S也是⼀种3引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。

STM32F0DISCOVERRY 在Keil MDK中调试环境设置说明一、Keil MDK版本建议使用Keil MDK的V4.50及以上版本。

注：其它低版本中不包含STM32F0系列芯片，以前用Keil MDK 4.20调试Nuvoton 的M0，现在用它调试STM32F0，好像不能下载程序，所以建议还是用高版本较好。

二、安装st-link_v2_usbdriver从ST网站上下载st-link_v2_usbdriver驱动程序，直接安装。

安装完成后，使用USB A口转Mini-B口数据线连接F0DISCOVERRY和PC的USB口。

安装成功后在windows（win7）下的设备管理器中应可看到。

如下图：三、Keil MDK调试环境设置打开Keil MDK开发环境，在project菜单栏下打开Discovery_Demo程序。

点击Target Options选项。

在Debug栏选择“ST-Link Debugger”下拉菜单，点击右侧“Setting”。

在“Setting”中选择“Flash Download”选项。

在“Programming Algorithm”栏中点击“Add”,选择“STM32F05x Flash”，如下图。

其它为默认状态即可。

四、编译、下载程序代码设置完毕后，在Keil MDK中重新编译Discovery_Demo程序，编译成功后，在“Flash”菜单栏中选择“Download”选项，即可将程序下载至F0DISCOVERRY中，在“Debug”菜单栏中，点击“Start/Stop Debug Session”进入调试界面，可进行单步、全局运行等调试。

注：如使用Keil MDK的较高版本，连接F0DISCOVERRY会进行版本升级，此时需将USB 线重新断开再连接（F0断电一次），即可升级操作。

当前Firmware为V2J15S0版本。

为了节省时间，本应用笔记将所有重要的信息归纳在了一起，并列出了需要注意的重要事项。
此处包含的所有信息对您的首个 STM32 设计同样极为有价值，虽然您不会立即关注移植项 目。现在研究这些问题将有助于您通过从一开始即针对兼容性进行设计来着手满足所有未来 的需求。要使用本应用笔记，您需要具备 STM32 的一般性知识，可通过 STM32 系列参考 手册、STM32 数据表以及 STM32 Flash 程序存储器编程手册来了解这些知识。

STM32 系列总览
STM32 平台为获得广泛且不断增长的产品组合打下了坚实的基础。随着适合各种新应用的新 产品的推出，整个 STM32 产品系列目前包含多个系列，其中包括 STM32F0、STM32F1、 STM32F2、STM32F4 和 STM32L1，每个系列都专门针对一个特定的领域：
本应用笔记简要介绍了整个 STM32 系列，并显示了在规划新设计或执行移植时首先需要考 虑的各个方面。对微控制器模块和外设进行了分组，它们要么完全兼容或与增强功能兼容， 要么按系列类型加以呈现。
