Design and Implementation of Digital Storage Oscilloscope Based on SCM

doi:10.3969/j.issn.1006-2475.2014.03.004

Abstract

Abstract: This paper introduces the design scheme of a simple digital storage oscilloscope, which is based on the single chip microcomputer(SCM) and dot matrix LCD. MSP430F149 low-power SCM is used as the control core. Signal is sampled by AD830E high-speed A/D chip, and the sampling values are stored synchronously in IDT7204. After being calculated and processed by SCM, the processed sampling values are sent to the LCD 12864 for displaying. The software design of data processing and graphic displaying is discussed mainly. This system is of advantages such as high reliability, high sampling frequency and low cost.

Key words: system, data acquisition, data processing, graphic displaying
