【Abstract】 This paper primarily introduces a high-performance AVR single-chip and USB protocol based data acquisition communication interface,combining high-speed FIPO data transmission chip AL422B,utilize ATMega128 single-chip and USB based interface chip Cypress AN2131 to design a high-speed data acquisition system with its corresponding USB software driver firmware program exploit process. Moreover,this system can realize high-speed data collecting and timely data handling,thus being broadly applied in transient signal and software wireless etc. with a bright outlook.更多还原
