【摘要】 利用VB中的MSComm控件实现了上位机(计算机)和下位机(单片机)之间的通信,通过Picture控件和Timer控件的配合使用实现了上位机对下位机数据的实时采集和动态图形显示,数据的动态图形显示为数据分析提供了一个动态、直观的印象,是数据分析的重要一环。文中给出的方法简单、实用,对于许多单片机应用系统有借鉴意义。更多还原

【Abstract】 The communication between host computer(computer) and lower computer(MCU) is realized by using the MSComm control in VB.And the real-time data acquisition and dynamic graphics display from host computer to lower computer are completed through the coordination of Picture control and Timer control.The dynamic graphics display of data provides a dynamic and visual impression to the data analysis,and becomes an important link for data analysis.The method given in this paper is simple,practical,and helpful to the application of many MCUs.更多还原
