倒计时计时器

说明：  APP下载简，麻烦开通一下，嘻嘻嘻嘻嘻嘻嘻(fyrthhuhhfhvhvjbjfnvjvubj)

说明：  为了解决低能量自适应聚簇分层（ ＬＥＡＣＨ）算法中簇头分布不均匀、 选举不合理以及路由方式单 一的不足，(in order to sovle the problem of unequal of cluster balances the energy consumption of nodes and prolongs the network lifetime)

说明：  这是我开发的一个车辆管理系统，里面包括原程序文件，开发程序文件以及系统运行程序！(development of a traffic management system, including inside the original files, the development program files and system operational procedures!)

msp430与si4713组合，实现RDS发射功能和FM发射功能(msp430 and si4713 combination, to achieve emission function and RDS FM transmitter function)

说明：  读取.pacp文件，提取里面的icmp、ip、udp等字段信息。 。。。。(Read the .pacp file and extract the icmp, ip, udp and other field information.)

求解二维热传导方程，文档中有过程和matlab程序。 本文利用有限差分法来求二维热传导方程的数值解，通过Matlab编程求解并作图，进而与解析 解做出的图进行比较，画出误差图。(Solving the two-dimensional heat conduction equation, there are procedures and MATLAB programs in the document. In this paper, the finite difference method is used to find the numerical solution of the two-dimensional heat conduction equation, and is solved and plotted by Matlab programming. The diagram made by the solution is compared, and the error map is drawn.)

button按下后，edit控件内容连续变化，button抬起后edit内容停止变化。自己做的例子，只以int数据为例。(button is pressed, edit control content changes continuously, button lift stops changing after edit content. Own example, an int data as an example only.)

说明：  利用 GUI 界面设计滤波器设计，有点难，但具有参考价值(Use GUI interface design, filter design, hard, but the reference value)

说明：  基于惯性传感器数据，使用四元数进行姿态角解算。(Based on the inertial sensor data, the attitude angle is calculated by quaternion.)
