说明：  多节锂电池充电管理系统 硬件参考设计和系统设计说明(Hardware Reference Design and System Design Explanation of Multi-section Lithium Battery Charging Management System)

说明：  C8051F的一个特点就是可以倍频到100M。近来用到。在单片机的调试通过其PLL倍频函数。供用到的朋友参考和借鉴。(One feature is the ability C8051F multiplier to 100M. Recently used. In MCU debugging functions through its PLL multiplier. Used for reference for a friend.)

实现ADT7310的温度读出功能，采用单次读，使用SPI通讯方式(Achieve ADT7310 temperature readout function, using single reading, using SPI communication mode)

本程序主要描述了几种彩色图像的特征提取的方法，包含颜色、纹理、的特征提取，还有图像的分割、sift特征点的提取与匹配

线性代数中计算行列式的值，输入行列式阶数，然后按行键入行列式可以求行列式的值(Calculating the determinant value in linear algebra. Enter the rank of the determinant, then type the determinant by row to find the determinant value)

C++ version (OpenCV) of the Matlab built-in functions accumarray.m and gradient.m

说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)
