为了实现IC卡门禁考勤系统中RS232-USB的接口转换,需要1台支持USB的主机,同时还要提供主机上用于与外设通信的驱动,一般由操作系统提供。此外,还需开发在主机上执行的客户端应用程序。在设备端,需要提供具有USB接口的主控制器芯片,以及编写主控制器上执行的USB通信代码和用于执行外设功能的相关代码。-disucssed IC card system RS232-USB interface conversion, Taiwan needs a USB host support, but also to provide mainframe and peripherals used for communication-driven, generally operating systems. In addition, the hosts also need to be developed to implement the client application. The equipment side, the need to provide USB interface with the host controller chip and the preparation of master controller on the implementation of the code and USB peripheral functions for the implementation of the relevant code. 下载
