用matlab实现tau_p变换

说明：  基于PCF8591的51单片机温度监测系统，串行AD转换，程序已验证可行，显示准确，含proteus仿真文件(Based on PCF8591 51 single chip temperature monitoring system, serial AD conversion, the program has been verified feasible, accurate display, including proteus simulation file.)

基于stm32的IIR滤波器设计，50HZ陷波器和高通滤波器，包括AD转换、串口打印等功能

能利用stm32f4+ov5640去识别黑色(Recognition of Black Using stm32f4+ov5640)

PL中断demo，包括timer、pl中断等，可参考(demo for zynq pl interrupt)

说明：  数值分析中的chebyshev拟合程序，学习数值分析的同学可以参考参考(Numerical Analysis of chebyshev fit program, students study and numerical analysis can refer to reference)

原厂只提供了SPI-master端的实现。但是实际工作中需要用slave端。提供源码作为参考

方程求根的是抛物线法则，写的不好。仅供参考(Roots of the equation is parabolic law, badly written. Reference)

可由管理者自行设定最多留言篇数，超过自动销毁，最多为100篇，可设定是否开放HTML语法，可寄送感谢函及新留言回报版主，更重要的是，有Form to mail的功能，也就是当访客选择留言加密时，该留言将直接寄送到版主的信箱，不在留言板上显示，功能够强了吧！当然还有很多管理功能，包括删除留言等(By managers to set their own maximum message number, more than self destruct, up to a maximum of 100, can be set whether to open the HTML syntax, may send a letter of appreciation and new messages return moderator, is more important, form to mail function, is when visitors choose to encrypt the message, the message will be sent directly to the moderator s mailbox, is not shown in the message board, function is strong enough it! Of course there are many management functions, including delete message)
