| Abstract: | Aiming at the requirements of transmission speed and development difficulty of various virtual instruments, an acquisition sys tem on basis of new USB2.0 high speed interface is designed. In order to transmit data quickly among high speed interfaces, this system employs the interface chip FT2232H of FTDI Company＇s fifth generation USB2.0, using its asynchronous FIFO interface to transmit da ta to FSMC interface of STM32F103, and applies LabVIEW to design PC interface as well as making use of the available Dynamic I.ink Library （DLL） and Firmware Library MCU to achieve high-speed data transmission. |
