微机USB 和RS485 通讯接口的软硬件设计

Abstract

中文摘要：文章使用最新的器件CP2101 桥接器作为核心,加上UART 和RS485 的转换芯片MAX1483 和一些附加电路IC 实现了USB 和RS485 转换器的硬件电路,介绍了作为USB 和UART 桥接器的新器件CP2101 的功能和用法,设计了在微机平台上与转换器进行通讯的软件 英文摘要：It has not been solved satisfactorily to communicate between USB and RS485 until the new bridge CP2101 comes out . The usage of the highly2integrated USB2to2UART Bridge Cont roller CP2101 was int roduced. The hardware interface circuit with CP2101 and MAX1483 as main core component s was implemented. At last the sof tware to communicate with bridge was designed.
