ATT7022E(26E 28E)三相电能专用计量芯片应用笔记（可用于三相三线和三相四线制）(ATT7022E (26E 28E) three-phase energy metering IC Application Note (available for three-phase three-wire and three-phase four-wire system))

编写一个中断处理程序，在主程序运行过程中，每隔10秒响铃一次，同时在屏幕右上角开窗口显示信息“The bell is ring!” 以及时、分、秒。(prepared an interrupt handling procedures, the main program process, beep every 10 seconds once, in the upper right open window screen display information, "The bell is ring!" And, minutes and seconds.)

鉴于stm32在keil平台上的触摸屏显示与校准触摸(touch screen display)

Advanced control of a doubly-fed induction generator for wind energy conversion

说明：  奇迹自动捡物按键精灵源码 可自动挂机，捡物文本源码(Miracle Source Wizard button automatically picking up objects)

光电式编码器程序,此程序可实现光电式编码器的位置读取(Photoelectric encoder program, which can read the position of photoelectric encoder)

dac0832用于进行数摸转换,单片机实现它的数据输入,用于函数信号发生器(dac0832 used for a few analog conversion, single-chip to achieve its data input for the function signal generator)

基于美国PARKER运动控制器开发的多轴运动控制界面，包括直线，圆弧插补等，界面友好，直观(PARKER motion controller based on U.S. developed multi-axis motion control interface, including linear and circular interpolation, etc., user-friendly, intuitive)

全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降(Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag)

底层调用了PCSC的通信库Winscard，可用于PC上读卡器与智能卡的通信(It calls the underlying communication library Winscard PC can be used on a PC to communicate with the smart card reader)
