xl系列单片机实验仪演示程序 LCD1602显示 步进电机控制器速度方向圈数可调 LCD1602显示 步进电机控制器速度方向圈数可调 K1－启动与停止步进电机运行 K2－设定步进电机运行圈数 （1-20圈） K3－设定步进电机转动方向 K4－设定步进电机运行速度 步进电机的转速控制分16档，数字越小，转速越快。 7.5度步进电机；周期7.5×4=30度，电机转动一圈需12个周期 资源：p1.0-p1.3接反向器74ls14，输出后接步进电机 p3.7接小喇叭提供按键音, p1.4-p1.7接端口按键：lcd1602插入实验仪(xl Series Singlechip Experiment LCD1602 demo program shows the direction of stepper motor speed controller circle shows the number of adjustable LCD1602 direction stepper motor controller lap speed of a few adjustable K1-start and stop the stepper motor running K2-setting step motor running a few laps (1-20 laps) K3-set stepper motor rotation direction of K4-setting speed of stepper motor stepper motor speed control minutes 16 stalls, the number of smaller, faster the speed. 7.5 degree stepper motor cycle of 7.5 × 4 = 30 degrees, rotating electric lap 12 cycles required resources: p1.0-p1.3 then reverse browser 74ls14, followed by stepper motor output p3.7 then provide a small speaker key tone, p1.4-p1.7 port access keys: lcd1602 insert Tester)

这是利用51单片机设计成的8路抢答器,主持人按下“开始”按键才开始抢答，并亮抢答允许指示灯(Host press the start button to vies to answer first, light and bright vies to answer first allowed.)

一个数字类型可提高开关电源的设计与实现，可以是很好的借鉴，但是要用特殊软件打开，把文件后缀复制到百度就可以找到(A digital type can increase the switching power supply design and implementation, can be a good reference, but use special software to open, copy the file suffix can be found on Baidu)

本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

采用模糊聚类法，对变压器的故障诊断，并且分析各种气体含量。(The fuzzy clustering method, on the transformer fault diagnosis, and analysis of various gases.)

上位机，与51单片机进行通信，将从单片机发送过来获得的信息显示在显示界面上。(PC, with 51 single-chip communication, sent from the information obtained from the microcontroller is displayed on the display screen.)

单片机lcd2864 MEUN菜单程序 已经调试好了。(LCD Menu)

程序是DS1302做的电子时钟，内部有DS1302的datasheet和具体的程序(Program is the DS1302 doing electronic clock within the DS1302 datasheet and specific program)
