说明：  为提升测量精度、方便数据传输管理, 设计并实现了以S3C44B0 处理器作为控制核心, CS5460 作为计量器件, 通过 USB 接口与上位机实现数据通讯的新型电能量测试系统 重点讨论了USB 接口程序的结构与实现。实践证明系统具有广 泛的适应范围。
(In order to make the electric monitor sys tem have improved accuracy of measurement,convenient data transmis s ion,and convenient and friendly human- machine interface,this paper introduces a new electric monitor sys tem which uses S3C44B0 as MCU,CS5460 as the chip of measure,and PDIUSBD12 as the chip of USB communication.It focuses on the s tructure and realization of USB interface program.The practice shows that the sys tem has wide sphere of application)
