摘要
使用LabVIEW编程环境,通过软件生成各种常用波形、公式波形、实时任意波形进行合成。再将数据通过串行口,下载到C8051F330微控制器的FLASH ROM,经过10位的D/A转换输出各种任意波形的模拟信号。并可以手绘任意信号输出,实现任意波形发生器的全部功能。当需要更改波形时,则在PC机软件上重绘波形图,重复采样、下载、存储、产生波形的工作过程。
Using the LabVIEW programming environment , through programming software generate general waveform, formula wave, real-time arbitrary waveform . further data through serial port, download to the microcontroller FLASH ROM After 10 D / A conversion output of the various arbitrary waveform analog signal. And the preparation of any real-time arbitrary signal output manually to achieve the full functionality of arbitrary waveform generator. When the need to change the waveform, in the PC software refresh waveform map, repeat sampling, downloading, storing, and the waveform generated process.
