–200°C to +760°C (–320°F to +1400°F) Leads to 480°C (900°F)
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：

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。

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。

STM32f10固件库使用手册中文版

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。

图5： STM32F051R8T6封装STM32F0系列让8位和16位微控制器市场上的客户享受32位微控制器的先进性能和STM32的DNA。

STM32生态系统让STM32成为微控制器市场标杆，同样，STM32F0的成功经验受益于STM32生态系统的实时性能、低动态功耗、先进架构、外设接口。

现在，即便成本敏感市场也同样可获得这些先进功能。

STM32F0让家庭娱乐产品、家电和工业控制设备具有最佳的设计灵活性和扩展性能。

该系列微控制器具有以下优点：•代码执行速度出色，让应用性能更加优异，代码效率更高，降低内存占用率•连接性能优异，先进模拟外设，支持各种应用•灵活的可选的时钟源，支持快速唤醒的低功耗模式，进一步降低动态功耗主要特性和功能:•内核和工作条件– ARM®Cortex™-M0 0.9 DMIPS/MHz，最高48 MHz– 1.8/2.0到3.6 V电源电压•连接性能优异– 6 Mbit/s USART– 18 Mbit/s SPI，数据帧长度在4和16位之间可灵活配置– 1 Mbit/s I2C快速模式+– HDMI CEC•增强控制功能– 1个16位3相电机PWM控制定时器– 5个16位PWM定时器– 1个16位基本定时器– 1个32位PWM定时器– I/O翻转频率高达12 MHz图6： STM32F051R8T6框图4.2 嵌入式ST-LINK/V2编程器及调试器STM32F0探索套件在电路板上集成了ST-LINK/V2编程器及调试器。

根据跳线状态设置（见表2），ST-LINK/V2有两种不同的使用方法：•向板载微控制器写入代码并进行相应的调试操作；•用一条数据线连接SWD接口CN3，对外部应用电路板上的微控制器进行代码烧录和调试操作；这个嵌入式ST-LINK/V2工具只支持通过SWD接口调试STM32微控制器。

若想了解调试和编程的详细功能，请查阅用户手册UM1075 (ST-LINK/V2 STM8和 STM32在线调试器/编程器)。

图7：典型配置表2 跳线状态跳线状态描述两个CN2跳线都接通ST-LINK/V2对电路板上微控制器进行代码烧录和调试操作两个CN2跳线都关断通过外部连接器CN3(SWD接口支持)对外部应用电路板上的微控制进行代码烧录和调试操作4.2.1 使用ST-LINK/V2向板载STM32F0烧录和调试代码只要把把两个跳线帽插入CN2接口，即可开启探索套件板向板载STM32F0烧录代码的功能，如图8所示。

请勿跳CN3接口，因为这可能会干扰ST-LINK/ V2与STM32F0探索套件上的STM32F051R8T6的通信功能。

图8： STM32F0探索套件接口图4.2.2 使用ST-LINK/V2向外部STM32应用板烧录和调试代码使用ST-LINK/V2向外部STM32应用板烧录和调试代码非常简单，只要拆除CN2上的两个跳线帽，如图9所示，然后按照表3所列引脚顺序，把外部应用连接到CN3调试接口即可。

注: 如果使用CN3的5号引脚连接外部应用电路板，SB19和SB22必须断开。
