32位单精度浮点数的乘加运算的C编程，感兴趣的可以看一下(Single-precision floating-point multiply-add operation of the C programming, interested can look at)

基于C51单片机的4*4矩阵键盘扫描。有仿真和程序，数码管显示，可以用于学习矩阵键盘扫描的基础知识。并可以进行扩展。(Based on the C51 microcontroller 4* 4 matrix keyboard scanning. There simulation and procedures, digital display, can be used to learn the basics of the keyboard scan matrix. And can be extended.)

实现STM32F103的触摸屏功能，适合入门的朋友(Realize the touch screen function of STM32F103, which is suitable for beginners)

风光互补路灯是一种得用风能和光能作为能源的路灯，因其具有不受供电影响，不用开沟埋线，不消耗常规电能，只要风力充足有阳光就可以就地安装等特点，因此受到人们的广泛关注，又因其不污染环境，而被称为绿色环保产品。(solar and wind LED system)

说明：  两个12V的电机驱动履带式底盘完成到制定目标运动的任务，可以通过点触屏进行无线控制。(Two 12V motor-driven crawler chassis complete the task of setting the target motion, which can be controlled by wireless touch screen.)

里面包含gx1121和Gx3001型，以及其他一些数字卫星接收机的设计方案，原理图，datasheet！绝对超值！(Which contains gx1121 and Gx3001 type, and other digital satellite receiver design, schematics, datasheet! Absolute value!)

说明：  ，用来控制带i2c的风扇板及读写e2prom都没问题，但是用来进行两个AVR单片机之间的通信时，有时会出现数据发送和接收错误（单片机AT1281的TWI引脚连接到i2c缓冲器PCA9513上，通信是在ATCA六槽机箱中进行，但是只用了两个槽位，其他的悬空(That is used to control with the i2c fan board and literacy e2prom all right, but used for two AVR of communication between the microcontroller, can appear sometimes sending and receiving data error (SCM AT1281 of TWI pin connected to the i2c buffer PCA9513, communication is in ATCA six slot chassis, but only two slots, other suspended)

基于MSP430舵机控制程序，SG90舵机，由PWM进行控制(MSP430-based steering control procedure, SG90 servos controlled by the PWM)

stm32f4 的usb鼠标主机程序，简单的修改即可成为自己的工程(stm32f4 usb mouse host)

这是一个关于红外解码及数码管显示的学习程序(This is one of the infrared decoder and digital display of the learning process)
