vs2005开发环境下面用C#编写的虚拟RFID串口模拟器。当接从串口收到一个数据的时候，工具自动回复一个你定制的报文串。前提是需要有虚拟串口。也可以手动向串口发送报文的功能。-vs2005 development environment written in C# using the following virtual RFID serial simulator. Upon receiving a data received from the serial port when the tool automatically go back to a string of your custom message. The premise that the need for a virtual serial port. You can also manually send a message to the serial port function.

这是modbus的应用。觉得这讲的很清楚，希望对大家有所帮助。-This is Modbus applications. Think it said very clearly that we want to be helpful.

I2C 通信中只涉及两条信号线，即时钟线 SCL 和数据线 SDA。时钟线为高电平时均可锁存数据（即时钟线上升沿到下降沿之间）。当时钟线 SCL 高电平时，如果把数据线 SDA 从高 电平拉到低电平，则表示通信开始；如果把数据线 SDA 从低电平拉到高电平，则表示通信结束。 代码中分了两个模块，iic_com 模块除了执行和 I2C 通信有关的代码设计外，还有按键检测部分，而 led_seg7 模块只是驱动数码管显示从 AT24C02 指定地址读出的数据。
