说明：  stm32制作简易信号源，产生方波三角波和正弦波(STM32 makes simple signal source to produce square wave triangle wave and sine wave)

PIC32是Microchip公司的32位单片机，此例介绍了如何使用mips16缩短指令集(Is Microchip' s PIC32 32-bit microcontroller, this example describes how to use the reduced instruction set mips16)

基于DS18B20的数字温度计的数码管显示(Based on DS18B20 digital thermometer digital display)

MSP430单片机的节点液位与电量程序，利用超声波测量液位。(Based on MSP430 ,measure the liquid level.)

PIC18系列单片机ADCC语言代码，提供给广大pic爱好者。(PIC18 Series MCU ADCC language code, available to the majority of PIC lovers.)

使用到蜂鸣器、Lcd1602、ZLG7289和串口，键盘实现加法器，控制LCD1602和蜂鸣器音乐播放。借助串口调试助手，可以用电脑发送字符，替代键盘，完成上述三种功能。(To use the buzzer, Lcd1602, ZLG7289 and serial port, a keyboard adder, and a buzzer control LCD1602 music player. With serial debugging assistant, a computer can send characters, instead of the keyboard, the above three functions.)

直流有刷电机驱动程序，基于STM32F4(DC brush Motor Driver code, based on STM32F4)

说明：  利用keil软件开发了单片机测温功能， 单片机是stm32 传感器是ds18b20(The temperature measurement function of MCU is developed by keil software. The MCU is STM32 and the sensor is DS18B20)

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.)

计算器，阈值为99999999，加减乘除运算都没有问题，protues电路图 和 汇编语言都有，仿真过了，没问题。(caculator， with protues and keil software it is successed。hope it is helpful for you)
