说明：  为了让广大的工科大学生理解单片机应用系统的开发方法，我们特别提供一个中小规模的典型应用案例，我们把具有详细注释的基于AT89C51单片机的心电信号发生器软件供大家参考，不妥之处请大家批评指出，愿此软件能够给你一点帮助，南昌航空大学自动化学院生物医学工程赵文龙供。2008年8月28日。
(In order to enable the broad masses of the engineering students to understand single-chip microcomputer application systems development methodology, we are particularly small and medium-sized to provide a typical application case, we have a detailed annotated AT89C51 single-chip microcomputer-based ECG Signal Generator Software for your reference, not properly requested of the U.S. criticism that this software would like to be able to give you a little help, Nanchang University of Aeronautics automation Zhao Wenlong Institute for Biomedical Engineering.
