摘要
以具有USB接口Cypress芯片为例,介绍USB接口芯片的硬件和软件开发过程。设计中利用接口简单、灵活、有高效的传输速率和即插即用特性的USB2.0芯片作为温度采集系统的数据通信硬件平台。利用Visual C++的API函数实现计算机与USB接口的通信数据交换,从而在计算机上实时观测温度采集数据的具体情况。
Takes the Cypress chip with USB intreface as an example, introduces the developing process of the hardware and software of the USB interface. Makes the USB 2.0 chip, which has simple and nimble interface, high transimitting speed and the feature of plug and play, as the hardware platform of temperature acquisition system for data communication. Uses API of Visual C＋＋ to realize data communication exchanging between computer and USB interface, thus observers the situation of temperature data collected in real-time on the computer.
