Visual Basic串口通讯调试方法。一个非常简单的方法.

用于在线仪表的 modbus,仅供参考，-online instrument for modbus connection, for information purposes only, thank you

实现函数发生器产生的波形能够在电脑显示器上显示。函数发生器通过GPIB卡与电脑连接并传输数据，电脑上通过LABVIEW软件环境完成与GPIB卡的数据通信。在LABVIEW环境下完成了对虚拟仪器前面板以及后台程序框图的设计与编程。在LABVIEW开发环境下，实现对GPIB控制时，采用VISA模块驱动的方法进行编程。设计结果在LABVIEW环境下的虚拟示波器能够实现示波器的功能，能够显示函数发生器所产生的任意波形。- achieve the waveform can be displayed on the screen of the computer which send out by the function generator. The function generator connect to computer through a GPIB card and transfer data. Labview can be communicated with GPIB card and save data on computer. The virtual instrument front panel design and background process diagram programming can achieved under Labview software environment. The realization of GPIB control, using VISA module-driven approach to program in Labview. The result of the design is that the virtual oscilloscope is able to complete the Real oscilloscope function in Labview.

实现数据链路层 串口间的通讯，可以调试网络间的简单连接-Data link layer communication between serial port, you can debug a simple connection between networks

UART测试代码，可以与实现下位机与上位机之间的RS232协议的UART通信测试-UART test code, can achieve the lower computer and the host computer RS232 protocol between the UART communications test

用于开发税务票据管理的软件，可以打印，生成报表-tax bills for the development of the management software, print, generate statements

Viertex 2 开发板的接口程序，使用VC编写。-100 2 development board interface, the use of VC prepared.

此例为单片机串口的应用!将串口外接一个串入并出的数字芯片,可实现在单片机的串口扩展成并口输出功能!-This case the application for the single-chip serial! Will add a string to the serial port and a digital chip can be realized in the single-chip serial port expansion into a parallel port output function!
