摘　　要：本文首先介绍了数据采集器的基本概念、作用和分类.通过对数据采集器中重要芯片的介绍,引出了基于USB2.0的便携式数据采集器的硬件和软件设计思路.最后描述了便携式数据采集器的发展情景.This paper introduces a multi-functional electronic organ system based on MCS-51 MCU, which has the function of playback, record and play. In the system, two octaves can be inputted using a 8 × 2 matrix keyboard. And the name of music which is playing or recording can be displayed on the LED nixie tube. Besides, the volume and tone of music score can also be displayed by the creative use of LED array. By the combined use of multiple functions mentioned above, the system can be used as an auxiliary tool in electronic organ learning, as well as a reference example of MCU synthetical application in MCU learning.
