摘要
虚拟示波器在应用中体现出简易、灵活、便携、易于与PC机通信的特点。该设计中采用超低功耗的MSP430F169单片机作为控制核心,实现模/数转换,它能保证高运算速度和系统的工作稳定。同时使用高速USB接口与PC机进行数据传输,在PC机端对信号进行分析和再现,实现信号的实时显示和信号的特征分析;系统采用USB供电,不仅可降低功耗,而且易于使用和携带。实验结果表明,该设计达到了预期目标。
Virtual oscilloscope is very valuable in electronic design, test and debugging, especially in college curriculum design, graduation project. Virtual oscilloscope is very simple, flexible, portable, easy to communicate with PC in the appli- cation. The ultra-low power MSP430F169 MCU was taken as a controller in this design to achieve analog-digital conversion. It can guarantee the high-speed operation and stable running of the system. In addition, a high-speed USB interface is used to conduct the data transmission with PC. The signal is analyzed and displayed in PC console to realize real-time signal display and feature analysis. The USB is applied to power supply to reduce power consumption. It makes application and carrying easy.
