自己编写的计算机与单片机通讯时，下位机的模拟系统-I have written single-chip computer and communications, the next bit machine simulation system

六种列举当前所有的串口方法-six methods for handling serial ports

PLC串口编程,通过RS232和RS485与上位机通讯.-PLC serial port programming, through the RS232 and RS485 communication with the host computer.

将串口通讯协议存储为一个通讯文件，可是随时将存储通讯协议文件调入计算机运行与下位机通讯可以实现通讯对话，-Serial communication protocol will be stored as a communications document, but to keep the communication protocol storage document transferred to the computer is running and the next-bit machine communication can realize communication dialogue

用vc操作串口的源程序，可以发送字符串及文件，使用简单方便。-vc operation with serial source, and the string can send documents, the use of simple and convenient.

vc++6.0写的串口操作的类-vc 6.0 write operation of the serial category

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.
