摘要
进行了基于ARM的任意波形分析仪的设计。该分析仪利用DDS产生任意波形,利用ARM开发板上的AD接口和GPIO口实现数据采集,RAM实现数据的存储,LCD实现数据的显示。软件部分使用C语言编写程序并利用ADS实现程序的编译运行,实现了低于60KHz频率正弦波、方波和三角波的显示和分析。该波形分析仪精度较高,轻巧方便,具有一定的应用价值。
The design and realization of the A R M - based arbitrary waveform analyzer is introduced in this paper. The arbitrary wave is produced from DDS . The data is sampled by A / D module through G P I O interfaces in the A R M board; stored into the RAM ; shown on the LCD . C language is used to program.The analyzer realizes wave display and wave analysis of sine wave, square wave and triangle wave below 60K H z frequency. The waveform analyzer has the advantages of high precision, light weight and convenience, and has certain application value.
