ST无传感器永磁同步电机控制培训讲义,基于stm32f103芯片,第二天内容(ST sensorless control theory based on STM32F103,day 2)

iOS 网络状态监测。网络实时检测，用到Reachability（自行下载）,需加框架:SystemConfiguration.framework ios程序需要用到网络检测，有些程序是刚启动时检测一次，而有些则从头到尾检测网络状态。(IOS network status monitoring.Real-time detection and Reachability (download), frame: SystemConfiguration.framework IOS programs need to use network detection, some detection once when the program is launched, while others detect the network status start to finish.)

永磁同步直线电机模型，已搭建完成，对初学者有帮助(Permanent magnet synchronous linear motor model has been set up is complete, help for beginners)

说明：  基于Freertos的ESP8266 AT指令实现MQTT(Implementation of mqtt with esp8266 at instruction based on FreeRTOS)

说明：  下面的程序利用友元函数求两点间的距离。请你将有关的程序补充完整，并总结为什么这里要用友元函数来求两点间的距离。(using friend to get the result.)

实现一基于单片机的电子密码锁的设计,电子密码锁的设计主要由三部分组成：矩阵键盘接口电路、密码锁的控制电路、最小系统。另外系统还有LED提示灯，报警蜂鸣器等。(Realization of a microcontroller based electronic password lock design, the design of electronic password lock consists of three parts: matrix keyboard interface circuit, password lock control circuit, the minimum system. In addition, the system also has LED tips, alarm buzzer, etc..)

单片机为at89s52控制步进电机正反调速实验,(The stepper motor positive and negative control experimental)

使用W5500网络芯片，利用HTTP协议，实现了远程下载程序到STM32ZE单片机。(W5500+HTTP+STM32+IAP)
