Description: 通用串行总线(USB)以其传输速度快、占用资源少、真正的即插即用等优点正在逐步成为通用的计算机与外设的接口而取代传统的RS232总线。以传统的RS232接口为数据通信通道的外部设备与PC的通信面临一个转换的问题。该文介绍的是基于FT232R芯片实现USB和RS232之间的转换模块的设计。使用此芯片优点是数据收发和协议转换工作全部由芯片独立完成,而无需干预。-Universal Serial Bus (USB) for its transmission speed, occupancy, fewer resources, and truly plug-and-play, etc. are gradually becoming a common computer and peripheral interfaces and replace the traditional RS232 bus. To the traditional RS232 interface for data communication channel of external devices and PC communications face a conversion problem. The introduction is based on the FT232R chip USB and RS232 converter module between the designs. The advantages of using this chip data transceivers and protocol conversion be done by the chip independently, without intervention. Platform: |
