CRC校验采用多项式编码方法。多项式乘除法运算过程与普通代数多项式的乘除法相同。多项式的加减法运算以2为模，加减时不进，错位，如同逻辑异或运算。-CRC polynomial used coding method. Polynomial multiply and divide computing process and the general polynomial algebra multiply and divide the same. Polynomial and subtract operations for the two to die, not into the Modified, dislocation, as logical XOR.

一个12路串口+3路Socket口的数据收发程序 嵌入式ucLinux操作系统下调试通过，可以作为程序开发者一个很好的借鉴，掌握通信协议基本原理-a Route 12 road Socket three serial data transceiver mouth procedures ucLinux embedded operating system debugging, as developers a good draw and master the basic tenets of Communication Protocol

这个代码可以用来与任何设备 （它支持 uart 串口通信） 串行通信。在超级终端，可以检查这种通信。你应该在您的系统上的串行端口。如果不是，然后下载虚拟串行端口仿真器。

一种任意方波信号的产生方法，非常简单，看看就会了，适合菜鸟。

不同于一般形式的软件编程，嵌入式系统编程建立在特定的硬件平台上，势必要求其编程语言具备较强的硬件直接操作能力。无疑，汇编语言具备这样的特质。但是，由于汇编语言开发的复杂性，它并不是嵌入式系统开发的一般选择。而与之相比，C语言--一种"高级的低级"语言，则成为嵌入式系统开发的最佳选择。-Unlike most forms of software programming, embedded systems programming based on the specific hardware platform, is bound to require its programming language with a strong ability to direct hardware. Undoubtedly, the compilation of language with such qualities. However, the assembly language development complexity, it is not embedded systems development in general choice. But compared with C language-- a "senior vulgar" language, embedded systems development as the best option.

应用背景使用c8051f020单片机做主机，控制led屏显示芯片带动led发光二级管，使用扫描方式可显示文字 字母等，关键技术由于c8051f020单片机的频率高，做主控制器可做到led亮度可调，无闪烁，稳定性好。本程序是32x24点阵的led模块，可以扩展。
