7.2.9Label combine to Sends bmp
According to the user added the label, the label text into the current interface.
Graphics gph = Graphics.FromImage(bm);
for (int i = 0; i < LB_MAX_INDEX; i++)
{
if (LbArray [i]!=null )

gph.DrawString(LbArray[i].Text, LbArray[i].Font, new
SolidBrush(LbArray [i].ForeColor ),
LbArray[i].Left, LbArray[i].Top );
}
bm.Save("bms.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
7.2.10Method of extracting partial data of label text
Create Bitmap Object.Combine partial bmp
Rectangle ra;
Bitmap bm, tm;
if (CurrentLabel != null)
{
bm = new Bitmap(320, 240);
ra = new Rectangle(0,0,320,240);
PicturePanel.DrawToBitmap(bm, ra);
Graphics gph = Graphics.FromImage(bm);//Partial data combine.
gph.DrawString(CurrentLabel.Text,
CurrentLabel.Font, new
SolidBrush(CurrentLabel.ForeColor),
CurrentLabel.Left, CurrentLabel.Top);
ra = new Rectangle( CurrentLabel.Left,
CurrentLabel.Top,
CurrentLabel.Width,
CurrentLabel.Height);
tm = bm.Clone(ra, PixelFormat.Format32bppArgb ); //Convert partial data
tm.Save("str.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
}

7.2.11 The timed loop transmission processing
Used the timer interrupt control the bmp loop send,and control the bmp switch display
private void timer_send_Tick(object sender, EventArgs e) //Timed send
{ if (listBmpFile.Items.Count == 0) //Check the count is not zero
return;
timersend.Stop(); //Stop timer count.
if (listBmpFile.SelectedIndex == listBmpFile.Items.Count - 1)
{
listBmpFile.SelectedIndex = 0; //loop
}
else
listBmpFile.SelectedIndex = listBmpFile.SelectedIndex + 1;
LoadBmpToPicPanl(listBmpFile.SelectedItem.ToString());
//convert bmp
SendCurrentBmp(); //send bmp
LoadBMP.Enabled = false;
SendImage.Enabled = false;
timer_send.Start(); //send over,then start count.
}
7.2.12 Add label function
Users add labels by clicking button of add label, Check the free label content, Then insert new label.
private void button1Click(object sender, EventArgs e) //Added label
{ nt i;
for ( i = 0; i < LB_MAX_INDEX; i++)
{
if (LbArray[i] == null)
{
InsertLbArray(i);
i = LB_MAX_INDEX + 1;
}
}
if (i == LB_MAX_INDEX)
MessageBox .Show ("Max Number!","Note");
}
private void InsertLbArray(int index) //Insert label fun.
{
Point PressPoint = new Point();
Label lb = new Label();
lb.Text = "Input Your Data";
lb.Size = new Size(50, 25);
//lb.Location = new Point(PicturePanel.Top, PicturePanel.Left);
lb.Tag = index.ToString() ;
panel1.Controls.Add(lb);
lb.AutoSize = true;
lb.BackColor = Color.Transparent;
lb.BringToFront();
lb.MouseDown += delegate
{
//Set the Move flag.
PressPoint=Control.MousePosition;
};
lb.MouseUp += delegate
{
//Clear the Move Flag. MoveFlag = true;
Point cp = Control.MousePosition;
lb.Left = lb.Left + cp.X - PressPoint.X;
lb.Top = lb.Top + cp.Y - PressPoint.Y;
CurrentLabel = (lb);
textBox1.Text = lb.Text;
};
lb.MouseMove += delegate
{
lb.BackColor = Color.LightCoral;
};
lb.MouseLeave += delegate
{
//Clear the move Flag,and
lb.BackColor = Color.Transparent;
};
LbArray[index] = lb;
}
7.2.13 Send data to USB port
User driver function, Send data to USB port
private void SendToUSB(byte[] fbuffer, uint sendsize)
{
DWORD dwOptions = 0;
DeviceTabPage activePage = GetActiveTab(); //Check current connected USB device.
if (activePage == null)
return;
activePage.SelectPort(2); //Get the parameter of connected USB device
MP_Pipe activePipe = activePage.GetActivePipe();
DWORD dwPipeNum = activePage.GetActivePipeNum();
bool fControl = activePipe.IsControlPipe();
//Send data.
activePipe.UsbPipeTransferAsync(false , dwOptions, fbuffer, sendsize,
TIME_OUT, new D_USER_TRANSFER_COMPLETION (TransferCompletion));
}

9 General problem and fault handling
The general problem:
1 PC couldn’t distinguish this USB_LCD display module.
2 Can’t transfer data normally after distinguishing.
3 Can’t install USB device driving software.
4 Have problems When data sending.
5 Abnormal display effect
6 Testing software can’t run
Processing method:
1 If the device manager of your PC could not distinguish the USB LCD module, Please install again.
2 Check the USB cable is good or not.
3 Run “install.bat” file in CMD window.
4 Change USB cable, Test again.
5 Check the power input is good or not.
