【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。更多还原

【Abstract】 This paper describes a seamless interface between TMS320VC54X DSP and CY7C68001 (EZ- USB SX2) USB de- vice, 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 con- nection diagram demonstrating the interface between the two de- vices. In addition, it provides key codes and necessary annota- tions. The paper describes interface with the VC54x DSP , but most of details in this paper will be applicable to other MCU devices as well.更多还原
