摘要
针对数据采集系统控制和数据传输的特点,设计了基于FIFO的通用USB接口。接口体系采用集微控制器和USB控制器一体的EZ-USBAN2131QC作为主控芯片,编写了相应的固件和符合WDM模式的USB设备驱动程序。
According to the characteristics of control and data transfer in data collect system, a general USB interface system is designed which is based on FIFO. In the system, Cypress'EZ -USB AN2131QC chip is chosen, which is a compact integrated circuit that provide MCU and USB controller. Furthermore, the relevant firmware and USB device driver corresponding with WDM model are compiled.
