摘要
本文在分析CY7C68001通用USB2.0器件主要特征的基础上,阐述了一种TMS320VC54X与CY7C68001接口的方案,并针对TMS320VC54X扩展USB2.0接口进行了论述,给出了具体接口框图和关键代码。该方案对于使用其它微处理器开发基于CY7C68001的USB2.0功能也有良好的借鉴作用。
This paper describes a seamless interface between TMS320VC54X DSP and CY7C68001 (EZ-USB SX2) USB device,based on the analyses of features on CY7C68001.The two devices are interfaced through the external memory interface (EMIF) of the VC54X DSP. The document provides a pin connection diagram demonstrating the interface between the two devices. In addition, it provides key codes and necessary annotations. The paper describes interface with the VC54x DSP ,but most of details in this paper will be applicable to other MCU devices as well.
