Virtual instrument design based on ARM and USB2.0 / 医疗卫生装备

ABSTRACT

On the basis of ARMT core processor, a biological signal acquisition system with USB2.0 interface is presented in this paper. It is self-developed and Lab VIEW7 is taken as a host communicating software platform for the entire data communication system. The study is mainly focused on the firmware programming for USB chip, the development of USB WDM Driver, and the method for the calling of DLL from Lab VIEW7 to communicate with self-made hardware device.
