基于stm32开发的仿生鱼控制程序，串口与上位机通信部分(Stm32 development of bionic fish based control program, serial communication with the host computer parts)

三相异步电机变频调速仿真模型 仿真目的：改变三相异步电机的定子电源频率，观察电机定子电流，转速的变化规律。 (Three-phase induction motor speed regulation simulation model simulation purpose: to change the three-phase induction motor stator power frequency, and observe the variation of the stator current, speed.)

本代码是基于检测遥控飞机手柄输出的PWM信号频率，转换为角度信息，再作为步进电机移动输入量，最终实现使用遥控飞机手柄摇杆精确控制步进电机转动角度的目的，包含PWM频率检测模块和步进电机驱动模块等。(This code is PWM frequency signal detection based on the output of the remote control aircraft converted to handle, angle information, and then as the stepper motor movement input, and ultimately use the remote control aircraft joystick handle precise control of stepper motor rotation angle, including PWM frequency detection module and stepper motor drive module.)

DS1302+89c51的例程代码，实测可用(DS1302 STM32)

网络控制单片机proteus仿真 利用网络控制单片机的LED、LCD，我只是整理了一下，方便大家学习，版权归原作者，网页也麻烦站长做好了，有一个上位机，点击自动运行一段程序和打开www.mcufz.com/tcp.htm，之后会自动关闭，有的杀毒软件会报是病毒，放心使用。 开始要安装一个WinPcap软件，不安装它不能仿真，然后运行仿真文件，过一会可以看到LCD显示出了IP地址50。1。1。1 (Proteus simulation network control the use of single-chip microcontroller network control LED, LCD, I am just finishing a bit, to facilitate learning, belongs to original author, the website also do a good job of head trouble, there is a host computer, click Automatic operation for some procedures and open www.mcufz.com/tcp.htm, will automatically shut down after some anti-virus software will be reported to viruses, ease of use. WinPcap started to install a software, do not install it can not simulation, and then run the simulation documents LCD moment we can see the IP addresses shows that 50. 1. 1.1)

基于学习板的数字温度计设计程序，可以在数码管上动态显示实时温度，按键控制温度范围，可以使用蜂鸣器报警等。(Based on the study of the board, can design program digital thermometer in digital displays real-time temperature on the tube, button control temperature range, can use the buzzer alarm and etc.)

说明：  51单片机控制DS1302芯片，实现数码管的显示(The display of DS1302 digital tube controlled by 51 single chip microcomputer)

说明：  该源码实现51单片机之间符合modbus通信协议的通信(This code can achieve communications between MCS51 by modbus protocol. )

说明：  STM32F429示波器源代码，实测可用。(STM32F429 oscilloscope source code, the actual measurement is available.)
