In this paper, \request the help of a doctor , the development of more effective ECG equipment is very urgent ; 2 With a USB ( Universal serial Bus , Universal Serial Bus ) technology is more mature , as well as the outstanding advantages of its own , such as plug-and-play that is , the use of user-friendly ; interface , conducive to the system of portable applications , making it more widely used , many of our current interface is USB alternative . The system consists of two parts : the USB transmission of ECG acquisition and ECG . ECG signal acquisition some of the major hardware circuit design , including : analog signal processing before A / D conversion - ECG amplified and filtered , and the A / D converted digital signal processing - ECG data cache . ECG signal the USB terminal USB device and host side both work together . Terminal USB device , highlight the USB interface circuit design and firmware program . The host side focuses on the driver ( USB driver is a WDM driver mode ) the preparation of a brief introduction , and the preparation of the application . In order to have a better understanding of the system , some basic knowledge of the USB also introduced .
