摘要
针对存储测试系统的高速数据传输需求,设计了以单片机和FT245R为核心器件的USB接口电路,替代了传统的并行/串行接口。设计的USB接口支持USB 2.0协议,具有体积小、通用性好、操作简单、使用方便等特点,数据传输率达到1MB/s,满足了存储测试系统的数据传输率要求。
Using a MCU and FT245R as key components, an USB interface was designed for the requirement of highspeed data transmission in storage measurement system. The USB interface has the advantages of small volume, flexibility, conveniently and operation simply. The interface applies to USB 2.0 protocol, and the data transfer rate reaches as high as 1 MB/s, which meets the need of the storage measurement system.
