摘要
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.
