IP地址合法性判断，在VISUA C++6.0下运行通过-IP address to determine the legality of, at VISUA C++6.0 run through

说明：  这个程序是STM32F407的ARM7芯片，采集摄像头的数据通过TCP协议上传到服务器的单片机程序，绝对可以使用，是工业监控采集项目的单片机底层程序。(This program is the ARM7 chip of STM32F407. The data collected from the camera is uploaded to the server through TCP protocol. It can be used absolutely. It is the bottom program of the single chip computer of the industrial monitoring and acquisition project.)

(1)设计一个数字低通滤波器．设计指标如下： 通带内幅度衰减人大于1dB 阻带内幅度衰减大于15dB (2)编制计算设计的数字滤波器幅度特性与相位特性程序，并进行实验验证； (3)编制实现该数字滤波器程序并且模拟实现数字滤波 ①分别让满足所设计滤波器的通带、过滤带、阻带频率特性的正弦波通过滤波器，验证滤波器性能。 ②改变正弦抽样时间，验证数字低通滤波器的模拟截止频率是抽样时间的函数。((1) Design a digital low-pass filter. Design specifications are as follows: pass-band attenuation range of people within a range greater than 1dB stopband attenuation greater than 15dB (2) the preparation of calculation and design of digital filter amplitude characteristics and phase characteristics of processes and experimental verification (3) the preparation of implementation of the digital filter program and simulate digital filtering ① were designed to meet the pass-band filter, filter belt, stop-band frequency characteristics of the sine wave through the filter, verify the filter performance. ② change the sine sampling time, verify that the number of analog low-pass filter cutoff frequency is the sampling function of time.)

自己做的openwrt 的简单luci界面，利用的是html，而不是cbi控件，实现帐号密码的输入及认证，用post的方式和controller层进行数据传输，在mvc模式中实现view 和control的参数传递.(Control openwrt interface, the use of HTML, rather than CBI controls, to achieve the account password input and authentication, using post and controller layers of data transmission, in the MVC mode to achieve the parameters of view and Luci.)
