serial.h

使用USB2.0芯片CY7C68013A开发的usb转串口的源码。

#define   ReceiveMaxLength   1024

extern BYTE  xdata ReceiveBuf0[ReceiveMaxLength];     //接收缓冲区
extern WORD  ReceiveCount0;   //接收个数

extern BYTE  xdata ReceiveBuf1[ReceiveMaxLength];     //接收缓冲区
extern WORD  ReceiveCount1;   //接收个数


extern void SerialPort_Init();
extern void Serial_SendString(BYTE xdata *point, WORD length, BYTE flag);
extern void Serial_SendChar(BYTE source, BYTE flag);
