单片机红外遥控系统 ，该文章详细的介绍了用单片机实现红外遥控。(SCM infrared remote control system, the article describes in detail the infrared remote control with MCU.)

基于KEIL C51和MC55模块的短消息发送和接收程序源代码,C51控制，AT命令实现(based KEIL C51 and MC55 module of SMS sending and receiving the source code, C51 control, AT commands)

代码说明： 需要建立汽车模型的朋友请看看吧！这么长了还短 垃圾网站 (Need to build car model friends look out! )

说明：  基于stm32单片机做的无刷直流电机的矢量控制(Vector Control of Brushless DC Motor Based on Stm32 Single Chip Microcomputer)

巡线电脑鼠的程序，可以下载到51单片机中测试，程序可以用，纯手动编写，希望采纳(The Program of Patrolling Computer Mouse)

说明：  STM32 的GPIO操作示例程序代码, 试用与Keile环境STM32F103代码(STM32 GPIO operation code)

本文将选用一块支持 BDS/GPS 双模定位并具有低功耗特 点的芯片 ATGM332D-5N-3X 作为手持定位终端的定位模块。 ATGM332D-5N-3X 支持两种卫星导航系统进行组合定位，包括中国的 BDS （北斗卫星导航系统）， 美国的 GPS 。该模块具有 32 个跟踪通道，两个卫星导航系统的 GNSS 信号可同 时被接收，从而实现联合定位的功能。 ATGM332D-5N-3X 模块具有高灵敏度、 低功耗、低成本等特点，适用于船舶导航、车载导航、可穿戴设备等。(This article will choose a piece of support BDS/GPS Dual mode positioning with low power consumption Point chip ATGM332D-5N-3X As a positioning module for a handheld positioning terminal. ATGM332D-5N-3X Support two satellite navigation systems for combined positioning, including China. BDS (Beidou satellite navigation system), American GPS . The module has Thirty-two A tracking channel, two satellite navigation systems GNSS Signal can be identical It is received and the function of joint location is achieved. ATGM332D-5N-3X The module has high sensitivity, Low power consumption, low cost and other characteristics, suitable for ship navigation, vehicle navigation, wearable devices, etc.)

本程序可以读取电离层IONEX数据，可以运行，程序流畅简洁，清楚易懂!!(The program can read the ionosphere IONEX data, you can run the program smoothly simple, clear and understandable!!)

基于STM32F103R8的PID算法例程，PWM输出控制信号，ADC输入反馈信号，形成闭环控制，完整工程源码。(PID algorithm based STM32F103R8 routines, complete engineering source, PWM output control signal, ADC input feedback signal to form a closed-loop control.)

介绍了Topsis的基本原理，并通过两个示例说明了该方法的运用。(This paper introduces the principle of Topsis, and illustrates the application of this method by two examples.)
