WM8731是高性能的音频编码解码芯片，使用时需要通过IIC总线进行配置，本程序可以直观的设置各寄存器的参数，并自动生成C或C++语言代码。使用方便。(WM8731 is a high-performance audio codec chip, need to use IIC bus configuration, this procedure can be intuitively set the parameters of the register, and automatically generate C or C++ language code. Easy to use.)

PowerPCB/PADS封装库，原版安装后没有的，有常见的SO、SOIC、TSSOP等格式，省去自己画封装的麻烦(PowerPCB/PADS package library, after the original installation, and have common SO, SOIC, TSSOP and other formats, saved themselves the trouble of packaging draw)

c51的各种高级算法，和大学学习的计算方法很想，喜欢的朋友可以下载(c51 variety of advanced algorithms, the calculation method and universities want to learn, like a friend can be downloaded)

数码管动态显示，单片机学习者的很好的学习资料 (Dynamic display of digital control, microcontroller good learners learning materials)

说明：  19264液晶时钟，带按键，两页显示，带闹铃，带农历属相，二十四节气显示，功能非常全(24 solar terms with lunar week alarm)

单片机去控制PCF8591T去实现DA功能。 这个代码也要在示波器上才能观测到，DA输出一个正弦波。(Microcontroller to control PCF8591T to achieve DA function. This code also can be observed on an oscilloscope, DA output a sine wave.)

MPU6050传感器的六轴姿态解算算法代码(Six-Axis Attitude Solution Algorithmic Code for MPU6050 Sensor)

说明：  CCS所有功能例程,实现AD采样、pwm产生等功能(CCS all functional routines, realize AD sampling, PWM generation and other functions)

基于stc89c51与ds18b20的温度显示程序(Based stc89c51 temperature display program with ds18b20)

LCD1602液晶显示程序 显示字符 数字(LCD1602 LCD display program digital characters)
