加速度传感器很好用的，，可以移植的，你可以学习下，写的也不容易呢(Using an acceleration sensor,, you can refer to him,, a good, satisfying transplant)

这是针对XC878单片机的各模块的程序，包含有LCD，UART，AD，DA以及七段数码管等。适合移植和学习。(It is for each module XC878 microcontroller program includes LCD, UART, AD, DA, and seven-segment digital tubes. Suitable for transplant and learning.)

说明：  STM32读取ADXL345测量的值，并通过OLED模块显示(STM32 reads the measured value of adxl345 and displays it at OLED module)

模拟PID控制，参数可调，前面板中可观察响应曲线(PID simulation)

基于单片机计算器,可计算加减乘除，但是不能计算小数(Based on single chip calculator)

智能人体感应自动门程序，基于51单片机，主要应用于人员流动频繁的场所。(Intelligent human sensing automatic door program, based on 51 single, frequent staff turnover is mainly used in places.)

c51 可演奏的电子琴源程序与仿真，实现电子琴的基本功能(c51 source can be played keyboard and simulation, to achieve the basic functions of Keyboard)

自动寻找指定WIFI ssid并填入密码，自动打开wifi连上网。(Automatically find WIFI specified ssid and fill in the password, automatically open WIFI even surf the Internet.)

说明：  简单的PWM捕获，初学者比较适合。看看就好啦(Simple PWM capture, beginners are more suitable. Just look at it.)

这是基于STM32和FPGA的简易数字存储示波器(This is Simple Digital Storage Oscilloscope Based on STM32 and FPGA)
