因串口要运行Mon51进行仿真调试,故选一空闲IO模拟串口的TXD信号引脚,硬件为SST89E516,晶振为18.432,12时钟周期的单片机.
相关代码如下:
sbit TXD1 = P2^3; //定义模拟输出脚
//sbit RXD1 = P1^1; //定义模拟输入脚
bdata unsigned char SBUF1; //定义一个位操作变量
sbit SBUF1_bit0 = SBUF1^0;
sbit SBUF1_bit1 = SBUF1^1;
sbit SBUF1_bit2 = SBUF1^2;
sbit SBUF1_bit3 = SBUF1^3;
sbit SBUF1_bit4 = SBUF1^4;
sbit SBUF1_bit5 = SBUF1^5;
sbit SBUF1_bit6 = SBUF1^6;
sbit SBUF1_bit7 = SBUF1^7;
bit UART1_RI;
#if 1
void delay_bps()
{
unsigned char data uci;
  for (uci = 0; uci < 19;uci++);
} //波特率9600
/*
void delay_Halfbps()
{
unsigned char data uci;
//  for (uci = 0; uci < 6;uci++);  _nop_();_nop_();
  for (uci = 0; uci <50 ;uci++);
} //波特率9600
*/
#endif

#if 0
void delay_bps()
{
unsigned char data uci;
  for (uci = 0; uci < 6*9+8;uci++);
} //波特率19200
void delay_Halfbps()
{
unsigned char data uci;
  for (uci = 0; uci <25 ;uci++);
} //波特率19200
#endif
//unsigned char getchar2() //从缓冲区内读取一个字节数据
void putchar2(unsigned char input) //向发送缓冲区内写入一个数据
{
SBUF1 = input;
TXD1 = 0;  //起始位
delay_bps();
TXD1 = SBUF1_bit0;  //0
delay_bps();
TXD1 = SBUF1_bit1;  //1
delay_bps();
TXD1 = SBUF1_bit2;  //2
delay_bps();
TXD1 = SBUF1_bit3;  //3
delay_bps();
TXD1 = SBUF1_bit4;  //4
delay_bps();
TXD1 = SBUF1_bit5;  //5
delay_bps();
TXD1 = SBUF1_bit6;  //6
delay_bps();
TXD1 = SBUF1_bit7;  //7
delay_bps();
TXD1 = 1;    //停止位
delay_bps();
}
#define SendCharToPrint(x) putchar2(x)
void ChangePrintModeToChinese(void)
{
SendCharToPrint(0x1C);
SendCharToPrint(0x26);
}
void ChangePrintModeToEnglish(void)
{
SendCharToPrint(0x1C);
SendCharToPrint(0x2E);
}
void PrintFeedPaper(uchar ucLineCount)
{
SendCharToPrint(0x1B);
SendCharToPrint(0x4A);
SendCharToPrint(ucLineCount);
}
void PrintString(uchar *ucString)
{
uchar ucStringLen;
ucStringLen = strlen(ucString);
while(ucStringLen--)
{
  SendCharToPrint(*ucString++);
}
}
void TestPrint(void)
{
ChangePrintModeToChinese();
PrintString("2011年4月3日 21时20分50秒\n\r");
}

应用程序中用到的相关代码如下:
PrintString("----------------------------\n\r");
PrintString("  智能开关机记录仪启动\n\r");
Read_RTC_PCF8563(ucRTCBuff);
//将BCD码转换成16进制数据
for(ucCount=0; ucCount<7; ucCount++)
{
  ucTemp = ucRTCBuff[ucCount];
  ucRTCBuff[ucCount] = (ucTemp>>4)*10+(ucTemp&0x0F);
}
sprintf(ucTempBuff,"20%02d年%02d月%02d日 ",(uint)ucRTCBuff[6],(uint)ucRTCBuff[5],(uint)ucRTCBuff[3]);
PrintString(ucTempBuff);
sprintf(ucTempBuff,"%02d时%02d分%02d秒\n\r",(uint)ucRTCBuff[2],(uint)ucRTCBuff[1],(uint)ucRTCBuff[0]);
PrintString(ucTempBuff);
PrintString("----------------------------\n\r");
PrintFeedPaper(50);

效果图如下:

还有一段代码如下:
//打印当前记录
{
  uchar ucCount;
  uchar ucTemp;
  uchar xdata ucTempBuff[19];
  //将BCD码转换成16进制数据
  for(ucCount=0; ucCount<7; ucCount++)
  {
ucTemp = ucRTCBuff[ucCount];
ucRTCBuff[ucCount] = (ucTemp>>4)*10+(ucTemp&0x0F);
  }
  sprintf(ucTempBuff,"20%02d年%02d月%02d日 ",(uint)ucRTCBuff[6],(uint)ucRTCBuff[5],(uint)ucRTCBuff[3]);
  PrintString(ucTempBuff);
  sprintf(ucTempBuff,"%02d时%02d分%02d秒\n\r",(uint)ucRTCBuff[2],(uint)ucRTCBuff[1],(uint)ucRTCBuff[0]);
  PrintString(ucTempBuff);
  sprintf(ucTempBuff,"通道号:%02d 事件:",(uint)ucRecordNumber);
  PrintString(ucTempBuff);
  if(ucActionType == 0)
  {
PrintString("开机\n\r");
  }
  else
  {
PrintString("关机\n\r");
  }
  PrintString("***********************\n\r");
  PrintFeedPaper(15);

}
效果图如下:
