摘要
文章提出了一种基于德州仪器最新TM4C123GH6PM处理器的数字示波器设计。先介绍系统方案,包括信号采样和数据处理两部分;然后对软件设计进行描述,包括示波器各种功能实现的算法以及代码执行流程。所述的数字示波器设计能够实现测量峰峰值、直流偏置以及频率等电信号基本特征量,能够实时显示电信号的波形图像、具有触发功能。
This paper puts forward a design of digital oscilloscope based on TI＆#39;s latest TM4C123GH6PM processor. This article ifrst introduced the system, including signal sampling and data processing two parts; and then the software design is described, including the various functions of the oscilloscope to achieve the algorithm and code implementation process. Design of digital oscilloscope to measure the peak to peak value, the DC bias and frequency characteristics of the signal, can display real-time waveform image, has the function of signal trigger.
