这是自己用C++ BUILDER编的串口通信软件，该软件能接收单片机上传到PC机上的内容并显示出来，而且还可以编出波形。-This is their use of C++ BUILDER for the serial communication software can be uploaded to the PC to receive single-chip machine and display the content, but also for the waveform.

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

Labview的VISA串口通信，rs232通信，上位机软件能够向下位机读写数据，并能显示波形，调试通过，很好用。-Labview VISA serial communication, RS232 communication, PC software to read and write data to the PC, and can display the waveform, through debugging, very good use.

用VC++MFC编写的上位机软件，它可以通过rs232串口接收下位机发送来的数据并实时显示，还可以对波形作频率幅度检测，可以保存和回读波形。-Prepared using VC++MFC software, it can be through the RS232serial port to receive the client to send data and display in real time, but also on the wave frequency amplitude detec
