5.6 Connecting to Host controller 5.6.1 Example to connect an embedded controller

（Arduino)

R1 and R2 is a voltage divider to interface of 5V output to 3.3V input. Display output of 3.3V

signal is connected 5V input directory.

Hardware handshake is required to proper communication. If host has no CTS(Clear to send) input,

MBUSY output of display should be connected to an input port of host controller. Then software

need to check if display is not busy before serial data is transmited.

6 Software 6.1 Initialization and protocol

Communication protocol is no-protocol with hardware hand shake.

Controller can start display basic information without complicated initialization, because of

factory settings are prepared. To start with GU-D series, wait several hundred millisecond for

power up, then send ASCII character codes. Then try to send ESC sequence to call special settings

and functions.

6.2 Settings other than default GU-D series equips memory switches to customize power on default settings. UART baud rate can

be changed by a jumper setting (soldering is required). Other settings can be changed by memory

switches or commands.

screen image.

When you double-click Form1

dialog beside button1, it comes to be able to enter the definition of “Form1_Load”. Then add

serial port settings as follows.

Change COM2 to a suitable serial port number according to the system you want to use. Visual

studio generates gray colored lines already.

------ Start of List -----------

private void Form1_Load(object sender, EventArgs e)

{

this.serialPort1.PortName = "COM2";

this.serialPort1.BaudRate = 38400;

6.11.6 Using Shift-JIS code character display

Write character code for display module is Shift-JIS in Japanese. Since the internal code in

C# is Unicode, it is necessary to write by encoded characters to Shift-JIS. The example to display

at the click of “button2” by Japanese in C# is as follows;


{

const int JIS = 0;

CJK_setup(JIS); /*Setup JIS Kanji*/

string str = "日本語表示します";

Encoding sjisEnc = Encoding.GetEncoding("Shift_JIS");

int NumberOfBytes = sjisEnc.GetByteCount(str);

6.11.7 Graphic display

The bitmapped image converted into byte strings is written in VFD module. The image is displayed

immediately at the display area. When you write an image to a hidden area, the image appears

on the screen by the scroll display command.

/* Realtime Bitimage Display

*

* image: bitmap image

* X : Horizontal size in Bit

* Y : Vertial size in Byte (8Bit)

*

*/

private void DrawBitmap(byte[] image, int X, int Y )

{


bb[0] = (byte)0x1f;

bb[1] = (byte)0x28;

bb[2] = (byte)0x66;

bb[3] = (byte)0x11;

bb[4] = (byte)(X % 256);

bb[5] = (byte)(X / 256);

bb[6] = (byte)(Y % 256);

bb[7] = (byte)(Y / 256);

bb[8] = (byte)0x01;



{



}



{

this.serialPort1.Write(image, 0, X * Y);

}

}

6.11.8 Graphic display example

The following is a sample program that opens the graphic file and calls “DrawBitmap()”. This

program is added “Button3” and run as a click event. Please note that you cannot display which

is larger than display are size. Moreover, when the vertical resolution of the bitmap image

is not a multiple of 8, its remainder part is not displayed.


{

int i, j;

byte b2;

OpenFileDialog openDia = new OpenFileDialog();

if (openDia.ShowDialog() == System.Windows.Forms.DialogResult.OK)

{

Bitmap bmp = new Bitmap(openDia.FileName);

// @Show Bitmap on window

pictureBox1.Image = bmp;

// Transform Bitmap file into byte array

Byte[] bb = new Byte[bmp.Width * (bmp.Height/8)];

for (i = 0; i < bmp.Width; i++)

{

for (j = 0; j < (bmp.Height / 8); j++)

{

b2 = 0;

if (bmp.GetPixel(i, j * 8).G < 128) { b2 = 1; } b2 += b2;

if (bmp.GetPixel(i, j * 8 + 1).G < 128) { b2++; } b2 += b2;








- 50 -

if (bmp.GetPixel(i, j * 8 + 7).G < 128) { b2++; }

bb[i * (bmp.Height / 8) + j] = b2;

}

}

// Move Cursor to Home

moveCursor(0, 0);

// Call Realtime bitmap display

DrawBitmap(bb, bmp.Width, bmp.Height / 8);

}

openDia.Dispose();

}

6.11.9 Graphic scroll

The display module performs the scroll of the screen by moving data in Display RAM.

/*

* Graphics Hrizontal scroll

*/

private void GraphicsHrizontalScroll(int skip, int number, int speed)

{


bb[0] = (byte)0x1f;

bb[1] = (byte)0x28;

bb[2] = (byte)0x61;

bb[3] = (byte)0x10;

bb[4] = (byte)(skip % 256);

bb[5] = (byte)(skip / 256);

bb[6] = (byte)(number % 256);

bb[7] = (byte)(number / 256);

bb[8] = (byte)speed;



- 51 -



{



}

}

6.11.10 Graphic scroll example

The following is a sample program that is added and run as a click event of “button4”.

Please rewrite the X and Y size to accommodate your display module.


{

const int Xsize = 128; /* Horizontal screen size of display*/

const int Ysize = 32; /* Vertical screen size of display*/

const int speed = 1;

/*

* Scroll entire display

*/

GraphicsHrizontalScroll(Ysize / 8, Xsize, speed);

}

6.11.11 Display hidden area

The hidden area of RAM appears on the display area using with the scroll command "6.11.9." The following example is of a calling program implemented as a click event for “Button5”. Rewrite the X and Y size to accommodate your display module. private void button5_Click(object sender, EventArgs e)

{

const int Xsize = 128; /* Horizontal screen size of display*/

const int Ysize = 32; /* Vertical screen size of display*/




- 52 -

/*

* Show hidden area

*/

GraphicsHrizontalScroll(Ysize/8 * Xsize, 1, speed);

}

6.11.12 Character scroll Character scrolling is performed when the character is written. The horizontal scrolling is performed under the following conditions:

Condition 1: After setting the horizontal scroll mode, Condition 2: when the cursor reaches the right side of the screen, Condition 3: This display will initiate a scroll action by one character at next character

writing.

The scroll speed also needs to be set.

/*

* Horizontal Scroll Mode

*/

private void HorizontalScrollMD3()

{


bb[0] = (byte)0x1f;

bb[1] = (byte)0x03;



{



}

}

/*

* Horizontal Scroll Speed



- 53 -

*/

private void HorizontalScrollSpeed(int speed)

{


bb[0] = (byte)0x1f;

bb[1] = (byte)0x73;

bb[2] = (byte)(speed % 32);



{



}

}

6.11.13 Character scroll example Example illustrates a use of this command. It is a function as a click event of “button6”.


{


HorizontalScrollMD3();

HorizontalScrollSpeed(speed);



{

this.serialPort1.Write("Horizontal Scroll Mode Test...........................");


}

}

}

}

6.11.15 User window example

The following is a sample program that assign to a click event of “Button9”.

A 50x16 pixels user window is set to the upper left corner of the screen, and it is displayed

there as "Window". When character scrolling and a graphic display are performed without a break,

its data is written in this user window.

---------------------------------------


{



- 56 -

const int UserWindow1 = 1;

DefineUserWindow(UserWindow1, 0, 0, 50, 2);

SelectCurrentUserWindow(UserWindow1);



{

this.serialPort1.Write("Window");


}

}

----------------------------------------

Use the “SelectCurrentUserWindow(0); function” when you stop using the User window.

6.11.16 Sample of Touch Switch

This is a sample to get switch touch like an event.

Using with auto-transmit function of GU-D touch switch, serial data is paused and user routine

is called accordingly.

Please add Button8 and add a code as follows;


{


bb[0] = (byte)0x1f;

bb[1] = (byte)0x4b;

bb[2] = (byte)0x18;

bb[3] = (byte)0x02;

bb[4] = (byte)a;



{



- 57 -


// this.serialPort1.Close();

}

At property of serialPort1, click an event icon,

then double click "DataReceived" event.

In code edit window, enter following code.

Then add code to be executed at touch as

switchTouch() function.

void switchTouched(int sw, int onoff)

{

serialPort1.Write("\r\nTouchSwitch:");

if (sw < 10) { serialPort1.Write(" ");}

serialPort1.Write(sw.ToString());

if(onoff == 0)

{

serialPort1.Write(" OFF");

}else

{

serialPort1.Write(" ON!");

}

}

private void serialPort1_DataReceived(object sender,

System.IO.Ports.SerialDataReceivedEventArgs e)

{

int rd;

int sw;

int onoff;

rd = serialPort1.ReadByte();

if(rd == 0x11)

{



- 58 -

sw = serialPort1.ReadByte();

onoff = serialPort1.ReadByte();

switchTouched(sw, onoff);

}

}

And add a button9 to terminate touch switch reaction.


{


bb[0] = (byte)0x1f;

bb[1] = (byte)0x4b;

bb[2] = (byte)0x18;

bb[3] = (byte)0x00;

// this.serialPort1.Open();

8 Trouble Shooting 8.1 BUSY

GU-D series is required to use hardware handshake to prevent missing character(s). For

Asynchronous serial and SPI, MBUSY (Module Busy) signal is prepared.

For I2C interface, the handshake can be performed by either/both of "clock stretch" or/and MBUSY.

Especially scroll and wait command which may take very long time, hardware handshake is important

to achieve efficient programing.

8.2 Reset The display controller cannot accept data or commands during the internal power up

initialization. During this initialization, BUSY output is set to "BUSY", then do not write

data or commands during this period.

8.3 Why is not it displayed at all? Self-test mode GU-D series does not require initialization to start to show some characters. If the display

does not turn on at all, isolate the cause of failure such as wrong circuit drive or a display

module failure. As a solution, GU-D series has a self-diagnostic function to displays a test

pattern automatically at turning on.

TEST MODE

failure

No Display

8.4 How to set "TEST MODE" When "TEST" jumper is shorted at power up, GU-D series enters into self-test mode, and indicate

some message automatically without command or data from Host controller.

Self-test is useful to judge if cause of no display is by controller or display itself.

When "5V power is properly applied" and "Reset isn't low", no display on self-test-mode indicate

probable failure of display itself.

8.4.17 Location of TEST jumper

8.5 Program Macro termination

If your Program Macro code has no sequence to quit execution, and set auto-execution, you may

not be able to update program macro code. In that case, Test mode is an only way to terminate

the macro auto-execution.

P.Macro Termination

Power down

Short TEST jumper

Power up

Is Test mode started?

Keep power,

Open TEST jumper

Display is normal mode now.

Stop auto-execution setting.
