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。
Based on the analysis of the main features of the CY7C68001 Universal USB 2.0 device, a scheme of the TMS320VC54X and CY7C68001 interfaces is described. The TMS320VC54X extended USB2.0 interface is discussed. The specific interface block diagram and key codes are given. The program for the use of other microprocessors based on CY7C68001 USB2.0 development function also has a good reference.
