Description: 模拟Ethernet帧的发送过程
编写程序模拟Ethernet结点的数据发送流程。
具体要求：
1）用两个线程a和b来模拟Ethernet上的两台主机。
2）用一个双字类型变量Bus来模拟总线(将其初始化为“\0”，并且总线等于“\0”时表示总线空闲)。
3）两个子线程向总线发送自己的数据。数据用该线程的线程号进行模拟，发送数据用线程号和Bus的“或”操作进行模拟(即Bus＝Bus|ID，ID为该线程的线程号)。
4）每台主机须向总线上成功发送10次数据，如果其中某次数据发送失败，则该线程结束。
5）发送流程须遵循CSMA／CD。随机延迟算法中的冲突窗口取0.005。在数据发送成功(即Bus==ID)后，报告“ID send success”，产生冲突(即Bus！=ID)后报告“ID send collision”，发送失败(即冲突计数器值为0)后报告“ID send failure”。随着主机发送成功次数增加，报告其已发送成功的次数，如“主机A发送成功数=3”。

Description: 我以前曾发过V1.0版的，这是此版的修正版v1.1,修正了以前版本中的一个错误，即只能读一个数据后就再也读不出温度数据的错误。
这个是用Quartus II软件写的Verilog HDL语言写的与温湿度传感器DHT2x通信的代码. 里面有详细的注解. 主要用于DHT2x单线总线通信转换为8位并行总线通信,应用于具有外部8位总线访问功能的单片机直接读取温湿度数据. 此程序在EPM7128SLC-10中成功测试.
-I' ve once spoke V1.0 version, which is a modified version of this edition v1.1, fixes a bug in previous versions, that is no longer only after reading a data temperature data could not be read errors. This is done using Quartus II software, written in Verilog HDL language written with the temperature and humidity sensor DHT2x communications code. Which detailed footnotes. DHT2x mainly used for single-wire bus communication is converted to 8-bit parallel bus communication, used with an external 8-bit bus MCU read directly access features temperature and humidity data. EPM7128SLC-10 in this program successfully tested.

Description: 在没有专用总线主机(如DS2480B、DS2482)的情况下，微处理器可以轻松地产生1-Wire时序信号。本应用笔记给出了一个采用‘C’语言编写、支持标准速率的1-Wire主机通信基本子程序实例。1-Wire总线的四个基本操作是：复位、写“1”、写“0”和读数据位。字节操作可以通过反复调用位操作实现，本文提供了通过各种传输线与1-Wire器件进行可靠通信的时间参数-In case no dedicated bus host (such as DS2480B, DS2482), the microprocessor can easily generate 1-Wire timing signal. This application note gives a ' C' language supports the standard rate, 1-Wire host communication routines. 1-Wire bus four basic operations: reset, write " 1" , write " 0" and read data bits. The byte operation can be achieved by repeatedly invoked bit operating to provide a reliable communication through various transmission line and 1-Wire device parameters
