基于凌阳SPCE061A芯片的USB通讯可实现1.通过USB通讯，PC端应用程序能够控制LED灯的亮灭；2.PC端应用程序发送小于65字节的字符串给SPCE061A,SPCE061A接收PC发送的小于65字节字符串后将接收到的字符串发送给PC，PC接收字符并显示在界面。-based Sunplus SPCE061A USB chip can achieve a communication. USB communications, PC-side applications to control the LED lights to eliminate the bright; 2.PC-side applications to send less than 65 bytes of the string to SPCE061A. SPCE061A send the PC to receive less than 65 byte string will receive the string sent to the PC, PC to receive and display characters in the interface.
