摘要
RS232接口在嵌入式设备中应用广泛。为了充分利用USB接口即插即用的特点,详细介绍一种基于PL2303的RS232与USB转换的设计方案。PL2303是高集成度的通用串行总线(USB)与串口的接口转换器,可方便将现有基于RS232接口的设备转换为USB接口。该系统设计适合于便携式设备的研制和应用。
RS232 serial interface is used widely in embedded equipments,In order to make full use of advantages of USB, such as,plug and play,this paper introduces a convenient solution for connecting RS232 to USB based on PL2303 in details.PL2303 is a highly-integrated USB-to-UART bridge controller chip and is used to easily migrate the existing applications based on RS232 interface.The ssytem design is suitable for the development and application of portable equipment.
