serial

说明：  uart的vhdl实现代码 分模块设计和状态机设计 不错的，用它没错(UART achieve the VHDL code modular design and state machine design good, the right to use it)

实现对电能质量芯片ATT7022的控制，读取芯片的串口信息。(Realization of power quality control chip ATT7022, read the chip serial information.)

本程序为Franklin/keil C51源程序，可以在所有51系列（或兼容）单片机中运行(This procedure is franklin/keil C51 source program, can run in all 51 series (or compatible) single chip computer)

按键发串口数据，使用内部晶振24.5M不分频(Button sends serial data)

用 C++ 编写的 发送 接收串口工其软件，好用，可以参考一下(C++ prepared by the transmission and receiving serial software, good use, you can refer to)

串口控制的资料和源码，里面包含源码和学习资料(A serial port control information and source code)

Visual Studio下用C#和实现串口通信的完整工程(Implementing Serial Communication using C#)

串口通信,一个简单的例程,对学习WINCE很有帮助,尤其是串口编程.希望大家喜欢(Serial communication, a simple routine, learning WINCE helpful, especially the serial programming. I hope everyone likes)

说明：  通过cvi实现串口通讯的操作界面：通过RS232串口像下位机发送命令，并采集下位机的数据加以显示. (Serial communication through cvi interface: RS232 serial port through the lower position as to send commands and collect data to lower computer display.)

说明：  Communication connection for PLC
