说明：  基于51单片机的遥控小车开发，包括小车程序，以及遥控器程序。(The development of remote control car based on 51 single chip microcomputer includes car program and remote control program.)

基于atmega16的步进电机驱动程序，实现正反转及调速等功能。(Based atmega16 stepper motor driver, and achieve positive and speed functions.)

说明：  本系统是一套机载数据采集模块和远程终端。数据采集模块可以独立采集对象（小型飞机或航模）的姿态、高度等参数，并通过无线方式发送到远程终端；远程终端具有数据的实时显示、报警功能，并可记录数据完成回放。 在本设计方案中，使用MPU6050模块测量小型飞机的姿态角、航向角，使用气压测量模块与超声波测量模块来确定飞机的高度，使用WIFI模块进行数据传输，使用北斗卫星定位模块进行小型飞机的位置确定，在远程终端PC机上对数据进行解算，并采用MATLAB GUI对采集到的数据进行图形化的显示。(This system is a set of airborne data acquisition module and remote terminal. The data acquisition module can independently collect the attitude and altitude parameters of the object (small aircraft or model) and send them to the remote terminal by wireless mode. The remote terminal has the functions of real-time data display and alarm, and can record and play back the data. In this design, MPU6050 module is used to measure the attitude angle and heading angle of small aircraft, air pressure measurement module and ultrasonic measurement module are used to determine the height of the aircraft, WIFI module is used to transmit data, Beidou satellite positioning module is used to determine the position of small aircraft, and data is obtained on remote terminal PC. The calculation is carried out, and the collected data is displayed graphically by using MATLAB GUI.)

使用stm32在KEIL mdk 的环境下 实现压控增益，其中用的DAC7311芯片和OPA830运放(The use of STM32 to achieve the VCO gain in KEIL MDK environment, the use of DAC7311 chip and the OPA830 op amp)

用KeilC编写的，在51单片机上运行的能够正确对zigbee串口通信控制的程序。(Written in KeilC, running on the 51 single-chip microcomputer can correctly control the serial communication of ZigBee program.)

以前电子竞赛时写的M3 ARM控制TFT液晶显示正弦波波形可以连贯的左移，没有闪烁感，我还写了一个也是正弦波左移，只不过有一点闪烁，我也上传了，你们需要可以找一下！(Writing contest before the electronic control M3 ARM TFT LCD sinusoidal waveforms can be coherent left, no flashes, I also wrote a sine wave is left, just a little flicker, I also uploaded, you need to be able to Get it!)

说明：  关于利用TCT40-16ＦＳ进行超声波测距的原理图，实物图，源码，看完之后对超声波测距将不再陌生．(Conducted on the use of ultrasonic ranging TCT40-16FS schematic, physical map, source, after reading will not be a stranger on the ultrasonic ranging.)

基于stm32f407的超声波模块测距，用串口显示，使用keil5编写，语言为C(Stm32f407 based ultrasonic module distance measurement, using serial port display, written in keil5, the language is C)

最小的单片机PWM控制，电压控制PWM输出，智能化，体积小。(ADC control PWM output)
