Description: 伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。从波形上看，原有信号完全淹没于随机的噪声中，达到隐藏信号和抗干扰的目的。接受方只要有相同的伪随机序列，就可以通过伪随机序列很强的相关性将信号还原出来。而m序列，是扩频系统中最长用的伪随机序列。下面的代码就是基于matlab的生成m序列的代码，通过改变初始多项式的值，就可以生成不同阶数的m序列。-Pseudo-random code or PN code, spread spectrum communication is indispensable to a sequence. Spread spectrum communication, a simple to say that the adoption of a group of highly related to pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence there. From the wave point of view, the original signal completely submerged in the random noise to hide the purpose of signal and interference. As long as the recipient has the same pseudo-random sequence, the pseudo-random sequence can be a strong correlation to restore the signal out. And m sequence spread spectrum system is the longest of the pseudo-random sequence used. The following code is generated based on m sequences of matlab code, by changing the value of the initial polynomial, we can generate a different order of the m sequence.

Description: SG12232C graphic LCD液晶编程-This is an evaluation use of a small graphics LCD module. Last summer, SG12232C graphic LCD module has been sold sold for 1500 Yens from Akizuki Denshi and I bought it. However I could not find good application for the LCD module and it was going to go to junk box :-) so that I tried to use the LCD module temporary.
Only displaying any still image is not cool, first I tried to display an audio wave form in real-time like a digital oscilloscope, and then an FFT spectrum analysis too. The spectrum monitor seems to achived nice performance, in view of it is realized with a cheap microcontroller.
This can also be applied to radio frequency band.

Description: 其实是一辆能通过互联网，或500米以外的笔记本无线设施来远程控制的遥控汽车。由于在车上配备了一个网络摄像头，因此在视野范围之外都能够遥控该车，此外，车上还装了一个喇叭，您可以远程朝人们按喇叭。
我发现Linksys WRT54GL路由器非常的hacker-friendly（黑客友好），它运行Linux和一些已经被反向工程（reverse engineered）了的硬件。世面上有一大批针对这种路由器的固件版本（firmware version）可供选择，本项目用到的版本是可订制化的 Linux firmware Open-WRT。有了路由器的相关软件，对一大堆硬件进行改装也变得可能。因此，既然有这样一个廉价的、可改装的、嵌入式Linux系统可以随我所用——我知道我能做件很酷的事情，于是，Wifi机器人的想法诞生了。
本文的目的是提供一个该项目的概览，同时也列出了一些相关软件和电子产品的实施细节，但它并不是一个一步一步详细介绍如何制作Wifi机器人的手册，不过，那些具备一定电子和软件知识的人根据本文提供的信息也能够做出自己的Wifi机器人。我已经遵循GNU GPL v2发布了所有的源代码，因此，希望大家都来用这个源码，并尽量去完善它-In fact, is a remote control car remote control via the Internet, or 500 meters away from the laptop wireless facilities to. In the car is equipped with a webcam, outside the field of view to be able to remote control the car, the car is also fitted with a horn, you can remotely towards the people honk.
I found the Linksys WRT54GL router is very hacker-friendly (hacker-friendly), it runs Linux and has been reverse engineering (reverse engineered) hardware. The world face a large number for this router firmware version (firmware version) to choose the version used in this project can be customized Linux firmware Open-WRT. With the router software, it also becomes possible to a lot of hardware modification. Therefore, since there is such a cheap, can be modified, embedded Linux system with I used- and I know I can do the cool thing, Wifi robot idea was born.
The purpose of this paper is to provide an overview of the project, and also lists the implementation details of the software
