根据对应的按键值，对应输出相应的电容值，并做掉电检测(According to the corresponding key value, corresponding to the output of the corresponding capacitance values ​ ​ and do brownout detection)

红外编码显示在p1口的led灯上，方便大家利用遥控器。(Infrared codes display on the p1 mouth of led lights, facilitate everybody using the remote control. )

说明：  红外编码发生器程序 自己编写 调试成功 大家可以看看(IR code generator program written to debug their success we can see)

自行车的里程表。基于51单片单片机最小系统开发的(The bike' s odometer. Developed based on 51 single-chip microcontroller minimum system)

STM32L152VB的AD采集程序，7通道DMA方式采集，通过串口发送到PC，本人查阅多方资料亲自编程测试，可直接用。附带STM32L152VB工程模板，本人根据资料自己建的。(The AD STM32L152VB acquisition program, 7 channel DMA acquisition, through the serial port to send to the PC multi access information, I personally programming test, can be directly used. With STM32L152VB project templates according to the data, I built myself. )

direct sparse solver for linear equations

此程序为4*4矩阵键盘，键盘自身不带电源电阻，八个接线，在程序中进行需进行软件拉高拉低以便按键扫描。 应用单片机为MSP430F5529。(4* 4 matrix keyboard without power resistors MSP430F5529)

说明：  一个基于kinect的鼠标小程序~~~用vs2008环境(A small program based on kinect mouse ~ ~ ~ with the vs2008 environment)

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.)

PWM调光 1、学习目的：利用定时器产生PWM，了解原理和使用方法 2、硬件要求：LED灯 定时器 3、试验现象：LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象(PWM dimming, learning objectives: the use of the timer to generate PWM understand the principles and use hardware requirements: LED lamp timer test phenomenon: LED lights from bright to off, gradually changes from off to bright, that is, adjusted optical phenomena)
