Sample code Introduction

Open COM Port Device

In Sample code /LCM.cpp lin 25

  portinfo_t portinfo ={
  '0',                         // print prompt after receiving
  9600,                      	// baudrate: 9600
  '8',                         // databit: 8
  '0',                         // debug: off
  '0',                         // echo: off
  '0',                         // flow control:none
  '4',                         // default tty: COM2
  '0',                         // parity: none
  '1',                         // stopbit: 1
   0    	                // reserved
  };
   PortSet(fdcom, &portinfo);
   /*******************init to clear the Screen*******************/
   fdcom = PortOpen(&portinfo); //Open the COM port devices
   PortSend(fdcom, &clrcom, C8); //Clear All screen message

Send the UP line message to LCM Device

In Sample code /LCD_CTLDlg.cpp lin 15 and 58

   char upline[C32]={0x1b,0x51,0x41}; //for LCM UP line command
   gets(message);
   sprintf(upline+3,"%s\r",message);
   PortSend(fdcom, upline, C32); //Send the message to LCM

Send the LOW line message to LCM Device

In Sample code /LCD_CTLDlg.cpp lin 16 and 66

   char lowline[C32]={0x1b,0x51,0x42}; //for LCM LOW line command
   gets(message);
   sprintf(lowline+3,"%s\r",message);
   PortSend(fdcom, lowline, C32); //Send the message to LOW Line
