摘要
应用CY7C646xx型电路进行通用串行总线(USB)接口的开发,实现计算机与数字信号处理器(DSP)目标板的数据通信。介绍CY7C646xx的内部结构及基于该电路的USB接口系统。详细讨论计算机端驱动程序和应用程序的编写及目标板端CY7C646xx固件程序的编写。
The USB interface based on CY7C646xx is developed, and the communication between the computer and the DSP target board is realized. The inside structure of CY7C646xx and the USB interface system based on this circuit is introduced. The driver program, application program and the firmware on the CY7C646xx target board are discussed.
