210 低功耗及电源结构介绍
（1）低功耗（low power mode）,适用于需要长时间运行且功耗敏感的应用场景，如便携式设备、物联网设备、智能家居系统等。
（2）STM32电源系统结构：VDDA供电区域（A为模拟量），VDD供电区域，1.8V供电区域，后备供电区域；
211 睡眠，停机，待机模式特点
（1）四种工作模式：运行、睡眠、停止和待机，上电后默认是在运行模式，睡眠、停止和待机这3种为低功耗模式，功耗等级由高到低；
（2）睡眠模式（sleep mode）：CPU停止工作，但所有外设（如ADC、通信接口等）仍然运行，时钟继续运转。
（3）停机模式（stop mode）：CPU和核心外围设备的时钟会停止，但部分唤醒源（如外部中断和某些定时器）仍然运行。
（4）待机模式（standby mode）：CPU、外围设备和时钟都被关闭，只保留唤醒逻辑和备份寄存器。
212 低功耗进入及唤醒条件
（1）低功耗进入：睡眠模式(WFI/WFE),停机模式(WFI/WFE+SLEEPDEEP+PDDS+LPDS),待机模式((WFI/WFE+SLEEPDEEP+PDDS);
注：WFI(wait for interrupt),WFE(wait for EVENT)
（2）低功耗唤醒条件:睡眠模式(任一中断/唤醒事件),停机模式(任一外部中断(在外部中断寄存器中设置)),待机模式(WKUP引脚的上升沿,RTC闹钟事件,NRST引脚上的外部复位,IWDG复位);
213 低功耗寄存器及库函数介绍
（1）寄存器：电源控制寄存器(PWR_CR)-PDDS,LPDS,电源控制/状态寄存器(PWR_CSR)-EWUP,WUF,System control register (SCB_SCR)-SLEEPDEEP,SLEEPONEXIT。
（2）库函数：HAL_PWR_EnterSLEEPMode(),HAL_PWR_EnterSTANDBYMode(),HAL_PWR_EnterSTOPMode(),HAL_PWR_DisableWakeUpPin();
214 低功耗实验
（1）实验目的：
1. 按下按键 2 ，进入低功耗模式（睡眠、停机、待机）；
2. 按下按键 1 ，退出低功耗模式；
3. 正常模式下，LED1 闪烁；进入停机模式，LED2 长亮，退出停机模式则 LED2 熄灭。
（2）添加key模块(保留key2键),编写低功耗初始化函数lpwr_init(),进入睡眠模式函数lpwr_enter_sleep(),进入停机模式lpwr_enter_stop(),进入待机模式lpwr_enter_standby();-(57. 低功耗实验-mian.c,lpwr.h,key.c,lpwr.h,key.h)-待测试
注：1.从停机模式唤醒，HSI RC振荡器选为系统时钟仅8MHZ,需要重新配置系统时钟72MHZ,stm32_clock_init(RCC_PLL_MUL9);
2.进入睡眠模式和停机模式前，需先暂停滴答定时器,防止由滴答定时器中断造成的唤醒；
3.待机模式下需关闭电压调节器，若用WKUP引脚唤醒的话，需使能WAKEUP引脚的唤醒功能，并清除唤醒标记。
4.停机模式唤醒后从"进入停机模式函数"后开始执行，待机模式唤醒后从"main.c函数"开头开始执行;

215 CAN介绍
（1）CAN协议，全称为Controller Area Network（控制器局域网络）,是一种基于差分信号的异步串行通信协议，采用双绞线作为传输介质。
低速CAN（ISO11519）通信速率 10~125Kbps，总线长度可达 1000 米。
高速CAN（ISO11898）通信速率 125Kbps~1Mbps，总线长度 ≤40 米。
特点：多主控制，系统柔软性，通信速度快、距离远，错误检测与恢复，故障封闭功能。
216 CAN物理层介绍
（1）CAN网络通常由CAN控制器(负责处理数据的收发和协议转换)、CAN收发器(负责将控制器的数字信号转换为差分信号进行传输，同时也负责将总线上的差分信号转换为数字信号供控制器处理)和双绞线组成。
（2）高速CAN即闭环CAN总线，低速CAN即开环CAN总线，高速CAN总线两端接了120Ω的终端电阻(主要作用是匹配总线阻抗，提高信号质量，减少回波反射)。
（3）电平标准：高速CAN(显性电平表示逻辑0,通常CAN_H和CAN_L有2V的压差,隐性电平表示逻辑1,通常CAN_H和CAN_L有0V的压差);
低速CAN(显性电平表示逻辑0,通常CAN_H和CAN_L有3V的压差,隐性电平表示逻辑1,通常CAN_H和CAN_L有-1.5V的压差)
217 CAN数据帧详解
（1）CAN帧种类：数据帧（Data Frame），遥控帧（Remote Frame），错误帧（Error Frame），过载帧（Overload Frame），帧间隔（Interframe Space）。
（2）数据帧：数据帧包括必要的帧头、标识符、控制位、数据长度代码、数据域、CRC校验码和应答域等部分。数据帧又分为标准帧(CAN2.0A)和扩展帧(CAN2.0B)，主要体现在仲裁段和控制段。
数据帧由7段组成：帧起始（Frame Start），仲裁段（Arbitration Field），控制段（Control Field），数据段（Data Field），CRC段（CRC Field），应答段（ACK Field），帧结束（Frame End）。
218 CAN时序及仲裁机制
（1）CAN总线以"位同步"机制，实现对电平的正确采样,位数据都由四段组成：同步段(SS)、传播时间段(PTS)、相位缓冲段1(PBS1)和相位缓冲段2(PBS2)，每段又由多个位时序Tq组成。采样点位于PBS1 结束处。
（2）CAN总线的时钟同步机制：
1.硬同步-帧的起始位（SOF）同步，
2.软同步-在帧的后续数据位中进行，接收节点检测到数据位的跳变沿不在自身的同步段内，则会通过延长或缩短相位缓冲段的时间来调整自身的位时间，以重新获得同步。
（3）多个单元同时开始发送时要进行仲裁，仲裁机制为:
标识符优先级-(数据帧的起始部分为数据的标识符（ID）,标识符的数值越小，优先级越高)，
逐位仲裁-(按照标识符的位顺序逐位进行仲裁)，
显性电平优先-(显性电平（逻辑0）的优先级高于隐性电平（逻辑1）)。
219 CAN控制器及模式介绍
（1）STM32 CAN控制器：STM32的bxCAN，即基本扩展CAN（Basic Extend CAN）。
（2）协议支持(支持CAN协议2.0A和2.0B的主动模式);高波特率(波特率最高可达1兆位/秒);时间触发通信(支持时间触发通信功能);发送功能(3个发送邮箱);接收功能(具有3级深度的2个FIFO（First In First Out，先进先出队列）);
（3）CAN控制器的工作模式：初始化模式(禁止报文的接收和发送,可以对CAN控制器的相关寄存器进行配置)、正常模式(可以向总线发送或接收数据)和睡眠模式(CAN控制器的时钟停止，但软件仍然可以访问邮箱寄存器)。
（4）CAN控制器的测试模式有三种：静默模式(CAN控制器可以正常地接收数据帧和远程帧，但只能发出隐性位，而不能真正发送报文)、
环回模式(CAN控制器会把发送的报文当作接收的报文并保存)和环回静默模式(结合了静默模式和环回模式)。
220 CAN控制器框图
（1）CAN控制器框图主要由4部分组成->
CAN控制内核：包含各种控制/状态/配置寄存器，用于配置CAN控制器的模式、波特率等参数。
发送邮箱（Transmit Mailbox）：用来缓存待发送的CAN报文。
接收FIFO（First In First Out）：缓存接收到的有效CAN报文。
接收过滤器（Receive Filter）：筛选接收到的CAN报文，只将符合特定条件的报文保存到接收FIFO中。
（2）有效报文指的是（数据帧直到EOF段的最后一位都没有错误），且通过过滤器组对标识符过滤。
（3）过滤器根据位宽划分：16位（用于标准帧）和32位（用于扩展帧）。
（4）过滤器选择模式可设置：屏蔽位模式(选择出一组符合条件的报文)或标识符列表模式(选择出几个特定ID的报文)
221 CAN控制器位时序
（1）CAN控制器时序分为3段，SYNC_SEG,时间段1(BS1),时间段2(BS2)
（2）波特率=1/正常位时间，正常位时间=1tq+tBS1+tBS2;其中tBS1=tq(TS1[3:0]+1),tBS2=tq*(TS2[2:0]+1),tq=(BRP[9:0]+1)*tPCLK,
这里tq表示1个单元时间,tPCLK=APB时钟周期,TS1[3:0],TS2[2:0],BRP[9:0]在CAN_BTR寄存器中定义;
222 CAN控制器寄存器及库函数介绍
（1）CAN控制器寄存器：CAN控制和状态寄存器(CAN主控制寄存器 (CAN_MCR),CAN发送状态寄存器 (CAN_TSR),CAN接收FIFO 0寄存器 (CAN_RF0R),CAN位时序寄存器 (CAN_BTR) 等)，
CAN邮箱寄存器(发送邮箱标识符寄存器 (CAN_TIxR),发送邮箱低字节数据寄存器 (CAN_TDLxR),发送邮箱高字节数据寄存器 (CAN_TDHxR)等),
CAN过滤器寄存器(CAN 过滤器主控寄存器 (CAN_FMR),CAN 过滤器模式寄存器 (CAN_FM1R)等)。
库函数：HAL_CAN_Init(),HAL_CAN_ConfigFilter(),HAL_CAN_Start(),HAL_CAN_AddTxMessage(),HAL_CAN_GetRxMessage(),HAL_CAN_GetTxMailboxesFreeLevel(),HAL_CAN_GetRxFifoFillLevel()等
223-224 CAN收发实验
（1）CAN基本驱动流程：CAN参数初始化(工作模式，波特率，功能设置等)->msp函数初始化(时钟，引脚，中断等)->过滤器设置->发送，接收函数编写->中断服务函数编写
（2）编写can初始化函数can_init(),can的msp初始化函数HAL_CAN_MspInit(),can发送数据函数can_send_data(),can接收数据函数can_receive_data();-(58. CAN收发实验-main.c,can.c,key,c,can.h,key.h)-待测试

225 MQTT基本介绍
（1）参考文章：https://www.lxlinux.net/e/stm32/mqtt-turorial.html
（2）MQTT:（Message Queuing Telemetry Transport，消息队列遥测传输）协议，基于TCP/IP协议栈构建的异步通信消息协议，是一种轻量级的、客户端服务端架构的、发布/订阅模式的消息传输协议。
MQTT原理：客户端向一「主题」「发布」消息，服务端处理并推送给「订阅」了该「主题」的其他客户端。
发布与订阅的特点：相互独立(客户端相互独立，彼此没有直接联系),空间分离(客户端只要连接同一个 MQTT 通讯网络,无论是互联网或者局域网都可以通讯),时间异步(客户端的发布与订阅无需同步)。
226 MQTT报文格式介绍
（1）MQTT报文：由固定报头、可变报头、有效载荷三部分组成，其中
固定报头（Fixed header），所有 MQTT 报文有，表示报文类型及报文的分组类标识。
可变报头（Variable header），部分 MQTT 报文有，报文类型决定了可变头是否存在及其具体内容。
有效载荷/消息体（Payload），部分 MQTT 报文有，存放报文的具体内容。
（2）固定报头由消息类型（message type）, 标志位（DUP、QoS Level、RET）, 剩余长度（Remaining Length）)这3部分组成；
227 OneNET基本配置
（1）云平台OneNET配置：OneNET官方网址(https://open.iot.10086.cn) ，新建产品及其下设备后，保存设备详情中的MQTT三元组(设备ID,产品ID,设备密钥)。
228 MQTT报文概述
（1）客户端向服务分别发送"CONNECT报文",“SUBSCRIBE报文”,“UNSUBSCRIBE报文”,“PINGREQ报文”,“PUBLISH报文”，
服务器向客户端分别回复"CONNACK报文",“SUBACK报文”,“UNSUBACK报文”,PINGRESP报文,无需回复。
229 CONNECT报文之固定报头和可变报文
（1）报文实例链接：https://q4p5s568ub.feishu.cn/docx/ECsSdCSGoooQvux7U1xcmGaLnNd?from=from_copylink
（2）CONNECT报文=固定报头+可变报头+有效载荷。
固定包头(2-6字节)：(MQTT控制报文类型+用于指定控制报文类型标志位)(1字节)+剩余长度(1-4字节),例：CONNECT 报文固定报头的十六进制是：10 XX
可变报头(10字节):协议名(6字节)+协议级别(1字节)+连接标志(1字节)+保持连接(2字节),例:CONNECT 报文的可变头的十六进制是：00 04 4D 51 54 54 04 C2 00 64
230 CONNECT报文之有效载荷
（1）有效载荷 = 长度+设备 ID + 产品 ID + token
注：token 是在 MQTT 协议中用于服务端与客户端对接的参数。由res+et+key+method+version这些参数组成,经token生成工具生成后转换为16进制。
这里的有效载荷仅适用OneNET，每个平台的MQTT报文基本一致，但是有效载荷会有一点不同。
OneNET 官方的token生成工具官网下载地址：https://open.iot.10086.cn/doc/v5/develop/detail/624,
et 的时间戳可以用这个在线工具转换:https://tool.lu/timestamp/，
可在网络调试助手中通过发送报文来确定报文长度。
231 剩余长度
（1）剩余长度=去掉固定报头报文的长度；
剩余长度是使用变长度编码方案，低7位（第0到6位）用于编码数据，最高有效位（第7位）用于表示是否有更多字节，最大可以使用4个字节。
（2）OneNET服务器地址：mqtts.heclouds.com : 1883
232 CONNACK报文
（1）CONNECT报文=固定报头+可变报头
固定报头(2字节)=(MQTT控制报文类型 + Reserved保留位)(1字节)+剩余长度(1字节)；例：20 02。
可变报头(2字节)=连接确认标志(1字节)+连接返回码(1字节)；例:00 00。
233 SUBSCRIBE与SUBACK报文
（1）SUBSCRIBE报文=固定报头+可变报头+有效载荷
固定报头(2字节)=(MQTT控制报文类型 + 保留位)(1字节)+剩余长度(1字节);例：82 XX
可变报头(2字节)=报文标识符(2字节);例：00 0A
有效载荷=长度+主题过滤器(N字节)+服务质量要求(1字节);
注：主题过滤器在OneNet产品开发中的设备开发/Topic管理提取后转16进制
（2）SUBACK报文=固定报头+可变报头+有效载荷
固定报头(2字节)=(MQTT控制报文类型 + 保留位)(1字节)+剩余长度(1字节);例:90 03
可变报头(2字节)=报文标识符(2字节);例：00 0A
有效载荷(1字节)=返回码(1字节);例:00
234 UNSUBSCRIBE与UNSUBACK报文
（1）UNSUBSCRIBE报文=固定报头+可变报头+有效载荷
固定报头(2字节)=(MQTT控制报文类型 + 保留位)(1字节)+剩余长度(1字节);例:A2 XX
可变报头(2字节)=报文标识符(2字节);例：00 0B
有效载荷=长度+主题过滤器(N字节);
注：主题过滤器在OneNet产品开发中的设备开发/Topic管理提取后转16进制
（2）UNSUBACK报文=固定报头+可变报头
固定报头(2字节)=(MQTT控制报文类型 + 保留位)(1字节)+剩余长度(1字节);例:B0 02
可变报头(2字节)=报文标识符(2字节);例：00 0B
235 PUBLISH报文
（1）PUBLISH报文=固定报头+可变报头+有效载荷
固定报头=(MQTT控制报文类型 + DUP+QoS等级+RETAIN)(1字节)+剩余长度(1字节);例:30 XX
可变报头=长度+主题
有效载荷=JSON格式的发布内容
注：主题在OneNet产品开发中的设备开发/Topic管理提取后转16进制
236 PINGREQ和PINGRESP报文
（1）PINGREQ报文=固定报文
固定报头(2字节)=(MQTT控制报文类型 + 保留位)(1字节)+剩余长度(1字节);例:C0 00
（2）PINGRESP报文=固定报文
固定报头(2字节)=(MQTT控制报文类型 + 保留位)(1字节)+剩余长度(1字节);例:D0 00
237 MQTT编程实战
（1）MQTT报文总结：
名称 报文流动方向 描述 公式

MQTT发布数据打包函数mqtt_publish_data(),mqtt接收函数mqtt_receive_handle(),mqtt发送响应函数mqtt_send_response(),mqtt发送心跳函数mqtt_send_heart(),
mqtt断开连接函数mqtt_disconnect(),mqtt发送数据函数mqtt_send_data();-(60. 温湿度上传OneNET平台-onenet.c,onenet.h)-待分析待测试
238 温湿度上传OneNET项目概述
（1）项目需求:使用 ESP8266 连接 OneNET 云平台，并通过 MQTT 协议上传 DHT11 获取的温湿度值
239 DHT11介绍
（1）DHT11内置一个电阻式感湿元件和一个NTC测温元件，并与一个单片机相连接（DHT11内部）。采用单总线协议，也就是使用一根DATA线进行数据的收发。
DHT11的DATA线一次通讯时间4ms左右，数据分整数部分、小数部分和校验位，具体为：8bit 湿度整数数据 + 8bit 湿度小数数据 + 8bit 温度整数数据 + 8bit 温度小数数据 + 8bit 校验位。
（2）DHT11工作时序：主机发送开始信号、DHT11 响应输出、主机接收 40bit 数据（湿度数据+温度数据+校验值），结束信号（可选）
（3）起始信号：主机拉低总线至少 18ms，然后再拉高总线，延时 20~40us
响应信号：dht11拉低总线 80us ,之后拉高总线 80us
位数据0表示方式:以50us低电平开始，高电平持续26~28us表示 0
位数据1表示方式:以50us低电平开始，高电平持续70us表示 1
结束信号：DHT11拉低总线50us，表示数据传输完毕，随后总线由上拉电阻拉高进入空闲状态
240-241 DHT11实验
（1）编写dht11输入初始化函数dht11_gpio_input(),dht11输出初始化函数dht11dht11_gpio_output(),dht11起始函数dht11_start(),dht11读1个字节函数dht11_read_byte(),dht11读数据函数dht11_read()。-(59. DHT11实验-main.c,dht11.c,dht11.h)-待测试

243 天气预报项目概述
（1）项目需求:使用 ESP8266 通过 HTTP 获取天气数据（心知天气），并显示在 OLED 屏幕上。
按键 1 ：循环切换今天/明天/后天天气数据；
按键 2 ：更新天气。
244 心知天气平台详解
（1）心知天气网址：https://www.seniverse.com/; 注册登录后获取密钥SkzfX1jdvaAJrPNak,查手册获取心知天气平台服务器 api.seniverse.com及端口号80,手册中获取近5天天气的api,
根据api获取自己想要了解的城市近期天气状况(例:https://api.seniverse.com/v3/weather/daily.json?key=SkzfX1jdvaAJrPNak&location=pingxiang&language=zh-Hans&unit=c&start=0&days=5 );
245 cJSON介绍
（1）github中DaveGamble中下载cJSON库文件,cJSON库文件可打包及拆解json格式,利用JSON在线工具可校验/格式化json代码;
246 项目框架搭建及OLED模块修改
（1）添加cJSON模块代码,esp8266模块代码,key模块代码,oled模块代码;oled中引脚修改,font中新增所需文字字模,修改oled汉字显示函数oled_show_chinese(),新增oled初始化显示函数oled_show_init();-(61. 天气预报项目-oled.c,oled.h,font.h)–待测试
247 esp8266模块代码完善
（1）esp8266中新增拷贝接收的数据函数esp8266_copy_rxdata(),获取天气函数esp8266_get_weather(),修改esp8266.h中TCP_SERVER_IP,TCP_SERVER_PORT宏定义,以及ESP8266_RX_BUF_SIZE大小。-(61. 天气预报项目-esp8266.c,esp8266.h)–待测试
248-249 weather模块代码编写
（1）修改startup_stm32f101xb.s文件中堆Heap_Size的值,新建weather.c,新增获取3天天气函数get_3days_weather();-(61. 天气预报项目-weather.c,weather.h)–待测试
（2）对获取3天天气函数get_3days_weather()进行解析;-(61. 天气预报项目-weather.c,weather.h)–待测试
