stm32F4 AD转换

说明：  是一个简单的程序，运用c#编写，非常实用，可以学学(Is a simple procedure, using c# written, very practical, you can learn)

lwIP is a light-weight implementation of the TCP/IP protocol suite

基于avr atmega16单片机ad，da源代码，并带lcd显示，usart通信(Based on avr atmega16 SCM ad, da source code, and with lcd display, usart Communications)

该程序可以实现将运动的人用方框选出，主要应用运动历史图（MHI）更新背景图，选出运动的人。

能够显示图片按钮，按下和弹起可以实现两种不同的效果。对UI界面有要求时可以使用。(Can display pictures and buttons, press and bounce can achieve two different results. There are requirements on the UI interface can be used.)

Equal area azimuthal projection

说明：  BFSK信号调制与解调，对加噪信号进行延迟差动处理，得到重构信号后，解调与初始信号对比。(BFSK Signal Modulation and Demodulation)

实现c++异步串口的封装，使用简单，便于移植

迷宫求解一般采用“穷举法”，逐一沿顺时针方向查找相邻块（一共四块－东(右)、南(下)，西(左)、北(上)）是否可通，即该相邻块既是通道块，且不在当前路径上。用一个栈来记录已走过的路径栈是限定仅在表尾(top)进行插入或删除操作的线性表。(Maze solving generally use the " exhaustive" one by one to find adjacent blocks in a clockwise direction (a total of four- East (right), South (down), West (left), North (on)) whether to pass, that the both channel blocks adjacent blocks, and not in the current path. Use a stack to record the path traversed stack is limited only in the tail (top) to insert or delete a linear form.)
