摘要
分析了心音数据采集系统对上下位机之间数据通信接口的需要,介绍系统设计思想、硬件接口电路及单片机C8051F000编程实现方法,并在上位机中讨论如何使用C++Builder和WindowsAPI函数进行接口编程,给出实用程序。
This paper analyses the requirements of serial data communication interface between upper and lower hosts in a heart sound sampling system, and then introduces the system design scheme, schematic of hardware interface and source codes of upper and lower hosts. C8051F000 and personal computer adopted as the lower host and upper host respectively, C++ Builder and Windows API functions are also used to implement the applications.
