How to use the DEMO application

1. COM Port selection
2. Open COM Port
3. Close COM Port
4. UP line message
5. LOW line message
6. UP line message send to LCM device
7. LOW line message send to LCM device
8. Check LCM all pixel work

Sample code Introduction

Open COM Port Device

In Sample code /LCD_CTLDlg.cpp lin 157

  if(m_SerialPort.InitPort(this,nPort,9600,'N',8,1,EV_RXFLAG|EV_RXCHAR,512)) //Set LCM to 9600.n.8.1
  {
  m_SerialPort.StartMonitoring(); //Open Com port monitoring
  m_bSerialPortOpened=TRUE; //Set COM port open 
  }

Close COM Port Device

In Sample code /LCD_CTLDlg.cpp lin 171

  m_SerialPort.ClosePort(); //Set COM port close
  m_bSerialPortOpened=FALSE;

Send the UP line message to LCM Device

In Sample code /LCD_CTLDlg.cpp lin 183

  if(!m_bSerialPortOpened) return; //check the com port was open
  UpdateData(TRUE);
  char szSend[30] = {0x1b, 0x51, 0x41}; //0x1b , 0x51 ,0x41 for LCM send UPline command
  sprintf(szSend+3, "%s\r", m_Sendmsg);
  m_SerialPort.WriteToPort(szSend); //Write command and message to LCM device

Send the LOW line message to LCM Device

In Sample code /LCD_CTLDlg.cpp lin 215

  UpdateData();
  char szSend[30] = {0x1b, 0x51, 0x42}; //0x1b , 0x51 ,0x42 for LCM send LOWline command
  sprintf(szSend+3, "%s\r", m_Sendmsg2);
  m_SerialPort.WriteToPort(szSend); //Write command and message to LCM device
