基于最小冗余线阵的谱相关共轭循环MUSIC算法(MUSIC algorithm based on conjugate cyclic spectral correlation minimum redundancy linear arrays)

12864上面的并行画线，可以画圆，三角形，正方形，直线，正弦波(12,864 above the parallel line drawing, you can draw a circle, triangle, square, line, sine wave)

基于K60的PID调速，飞思卡尔都要用到，很重要的(K60 is based PID control, Freescale must be used, it is important)

此文件是arduino mega 2560单片机与Matlab结合的应用，可以通过matlab观察arduino的输出，程序有详细的注解，里面包含了一些实例。适合初学者学习。(This file is arduino mega 2560 microcontroller applications in conjunction with Matlab, arduino output can be observed through matlab, procedures detailed comments, which contains a number of examples. Suitable for beginners to learn.)

zigbee cc2530无线数据接受与发送，以外接传感器MQ-2酒精传感器为例，内置协议栈，直接下载就行，IAR版本为8.1(zigbee cc2530 wireless data accepted and sent to the external sensor MQ-2 alcohol sensor, for example, the built-in protocol stack, the direct download on the line)

自动交通控制系统用红、绿、黄三支共两组发光二极管表示交通信号灯，利用单片机模拟有时间显示的定时交通信号灯控制管理。信号灯的变化规律可如下： 1）放行线：绿灯亮放行25秒，黄灯亮警告5秒，然后红灯亮禁止。 2）禁示线：红灯亮禁止30秒，然后绿灯亮放行。 3）当某一方向的红灯亮时，若该方向有车通过，则用扬声器声报警。（撞红灯信号可用3-5V模拟量表示）(Automatic traffic control system using red, green, yellow light-emitting diodes, said a total of three traffic lights, the use of single-chip analog time display on a regular traffic signal control and management. Changes of lights to be as follows: 1) Release Line: green clearance 25 seconds, the yellow light warning for 5 seconds, then the red light is prohibited. 2) ban shows lines: the red light is prohibited for 30 seconds, then the green light to release. 3) When the red light in one direction, if the direction of the car through, the alarm speaker sound. (Hit the red signal available 3-5V analog representation))

本程序利用特征线法计算管道水击的压力和流量(The program uses the method of characteristics to calculate the value of the pipeline water hammer pressure and flow values.)
