How to use the DEMO application

Image:lcmctl.JPG

  1. COM Port selection
  2. Confirm COM Port select
  3. Upline message enter
  4. Upline message send
  5. Clear upline
  6. Lowline message enter
  7. Lowline message send
  8. Clear lowline

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
