1.4 Connecting to a PC The GLK24064-25 connects seamlessly to a PC and it is an excellent means of testing the functionality and uploading new fonts and bitmaps. You will require a standard RS-232 9-pin serial cable such as the one pictured in figure 6 on page 3, as well as a modified 5V power adapter such as the one pictured in figure 3 on page 2. In order to connect your display to a personal computer follow these easy instructions: 1. Plug the serial cable into the com port you wish to use. 2.
1.5 Installing the Software 1.5.1 MOGD# MOGD# is the latest updated version of MOGD and can be used to manage font and graphics downloads as well as exercise all of the features of our graphical displays. MOGD# provides a new user friendly interface as well as many feature enhancements. To install MOGD# from the Matrix Orbital CD, follow the following steps: 1. 2. 3. 4. 5. 6. Insert the Matrix Orbital Cd-ROM into the Cd drive Locate the file MogdSharp.
2 Hardware Information Refer to the following diagram for this chapter: 1 DB-9 Connector 2 Power Through DB9 Jumper 3 Manual Override 4 Keypad Interface Connector 5 Power / Data Connector 6 Legacy Connector Jumper 7 Protocol Select Jumpers 8 File System Lock Jumper Figure 11: GLK24064-25 2.1 DB-9 Connector The GLK24064-25 provides a DB-9 Connector to readily interface with serial devices which use the EIA232 standard signal levels of ±12V to ±12V.
2.1.1 Power Through DB-9 Jumper In order to provide power through pin 9 of the DB-9 Connector you must place a solder jumper on the Power through DB-9 Jumper pictured in figure 13 below. The GLK24064-25 allows all voltage models to use the power through DB-9 option, see table 1 on the following page for display module voltage requirements. Figure 13: Power Through DB-9 Jumper WARNING Do not apply voltage through pin 9 of the DB-9 connector AND through the Power/Data Connector at the same time. 2.

Similarly, in order to change the display to TTL mode, simply remove the zero ohm resistors from the 232 or I2 C jumpers and solder them to the TTL jumpers. Figure 16: Protocol Select Jumpers 2.4 Keypad Interface Connector The GLK24064-25 provides a Keypad Interface Connector which allows for up to a five by five matrix style keypad to be directly connected to the display module. Key presses are generated when a short is detected between a row and a column.
2.5 Manual Override The Manual Override is provided to allow the GLK24064-25 to be reset to factory defaults. This can be particularly helpful if the display module has been set to an unknown baud rate or I2 C Slave Address and you are no longer able to communicate with it. If you wish to return the module to its default settings you must: 1. 2. 3. 4. 5. Power off the display module. Place a Jumper on the Manual Override pins 1 and 2 as pictured below. Power up the display module.
2.6 Filesystem Lock Jumper The File System Lock Jumper allows you to lock the file system on the GLK24064-25 so that no fonts or bitmaps can be either written or deleted from the on board memory. This feature is useful in order to protect data integrity of production units, if protection of other settings is required see Section 12.1. To lock the file system, solder a zero ohm resistor or use a solder jumper on the Filesystem Lock Jumper pictured in figure 19 below.
• Second, please ensure that the display module is set to communicate on the protocol that you are using, by checking the Protocol Select Jumpers. To change the protocol used by the display module see Section 2.3 on page 10. • Third, ensure that the host system and display module are both communicating on the same baud rate. The default baud rate for the display module is 19200 bps. • If you are communicating to the display via I2 C please ensure that the data is being sent to the correct address.
4 Communications 4.1 Introduction The commands listed in this chapter describe how to configure data flow on the RS232/TTL and I2 C port. The display has built in flow control which may be useful when long strings of text are downloaded to the display. Flow control is enabled or disabled by two commands.
4.2 Turn Flow Control On Syntax Hexadecimal Decimal ASCII Parameters Parameter full empty 0xFE 0x3A [full] [empty] 254 58 [full] [empty] 254 “:” [full] [empty] Length 1 1 Description The upper limit to issue an The lower limit to issue an Description This command enables flow control. When the buffer fills so that only [full] bytes are available, the display will return an “almost full” message (0xFE) to the host controller.
Description This command turns off flow control. Bytes may overflow the buffer without warning. Remembered No 4.4 Changing the I2 C Slave Address Syntax Hexadecimal Decimal ASCII Parameters Parameter adr Description 0xFE 0x33 [adr] 254 51 [adr] 254 “3” [adr] Length 1 Description The new I2 C write address (0x00 0xFF). This command sets the I2 C write address of the module between 0x00 and 0xFF. The I2 C write address must be an even number and the read address is automatically set to one higher.
Remembered Always Factory Default 0x50 4.6 Setting a Non-Standard Baud Rate Syntax Hexadecimal Decimal Parameters Parameter speed 0xFE 0xA4 [speed] 254 164 [speed] Length 2 Description Inputed LSB MSB from baud rate formula (12-2047). Description This command sets the RS-232 port to a non-standard baud rate. The command accepts a two byte parameter that goes directly into the mod16,000,000 ules baud generator.
5 Fonts 5.1 Introduction The GLK24064-25 comes loaded with the ’Small Filled’ and ’Futura Bk BT 16’ fonts by default however, it is capable of displaying any font that is uploaded to it in the correct format. MOGD# provides a simple method of generating font files from your installed fonts. For instructions on how to install MOGD# see Section 1.5.1 on page 7. 5.1.1 Font File Format A font file consists of three parts, a header, a character table and bitmap data. 1.

Description In order to upload a font to the GLK24064-25 you must first initiate the upload font file command (0xFE 0x24), you must then pass it a reference identification number, which must be unique for every font on the display module. You may then pass the display module the two byte file size, which needs to be transfered LSB, then MSB. The last part of uploading a font is transmitting the font file data. For detailed instructions on uploading a file to the GLK24064-25 see Section 11.1 on page 43.
Parameters Parameter lm tm csp Length 1 1 1 lsp 1 srow 1 Description Left margin: Location in pixels. Top margin: Location in pixels. Character Spacing: Amount of space in pixels between characters. Line Spacing: Amount of space between lines in pixels. Scroll Row: The Y location of the last row in pixels. Description Font metrics define where the characters are positioned on the screen, by setting where the rows and columns begin based on the [lm][tm][csp][lsp][srow] parameters.
6 Text 6.1 Introduction The GLK24064-25 is an intelligent display module, designed to reduce the amount of code necessary to begin displaying data. This means that it is able to display all characters and strings that are sent to it, which are defined in the current font, without much, if any configuration. The display module will begin displaying text at the top left corner of the display area, known as home, and continue to print to the display as if it was a page on a typewriter.
Remembered No 6.4 Setting the Cursor Coordinate Syntax Hexadecimal Decimal ASCII Parameters Parameter col row 0xFE 0x79 [col] [row] 254 121 [col] [row] 254 “y” [col] [row] Length 1 1 Description Column Row Description This command positions the insertion point at a specific pixel (X,Y), which references the top left corner of the font insertion point. Remembered No 6.
6.6 Auto Scroll Off Hexadecimal Decimal ASCII Syntax 0xFE 0x52 254 82 254 “R” Description When auto scrolling is disabled, text will wrap to the top left corner of the display area when the text reaches the end of the scroll row defined in the font metrics (the bottom right character position) see Section 5.4 on page 22. Existing text in the display area is not erased before new text is placed. A series of spaces followed by a “Cursor Home” command may be used to erase the top line of text.
Description The GLK24064-25 is capable of storing up to sixty-four font and bitmap files combined. In order to upload a bitmap to the GLK24064-25 you must first initiate the upload font file command (0xFE 0x5E), you must then pass it a reference identification number, which must be unique for every font on the display module. You may then pass the display module the two byte file size, which needs to be transfered LSB, then MSB. The last part of uploading a bitmap is transmitting the bitmap file data.
Parameter X Y W H D Parameters Description Length 1 1 1 1 1 Description Left bounds. Top bounds. Width Height Data Drawing a bitmap to the GLK24064-25, without first uploading the image to the memory can be a very useful feature for drawing images that are not used very often.
Parameters Parameter color Length 1 Description Drawing color (0: White, 1-255: Black). Description This command sets the drawing color for subsequent graphic commands that do not have the drawing color passed as a parameter. The parameter [color] is the value of the color where white is 0 and black is 1-255. Remembered No 8.3 Draw Pixel Syntax Hexadecimal Decimal ASCII Parameters Parameter x y 0xFE 0x70 [x] [y] 254 112 [x] [y] 254 “p” [x] [y] Length 1 1 Description X screen location.
Description This command will draw a line from (x1,y1) to (x2,y2) using the current drawing color. Lines may be drawn from any part of the display to any other part. However, it may be important to note that the line may interpolate differently right to left, or left to right. This means that a line drawn in white from right to left may not fully erase the same line drawn in black from left to right. Remembered No 8.
Description This command draws a rectangular box in the specified color (0: White, 1: Black). The top left corner is specified by (x1,y1) and the bottom right corner by (x2,y2). Remembered No 8.7 Drawing a Solid Rectangle Syntax Hexadecimal Decimal ASCII Parameters Parameter color 0xFE 0x78 [color] [x1] [y1] [x2] [y2] 254 120 [color] [x1] [y1] [x2] [y2] 254 “x” [color] [x1] [y1] [x2] [y2] Length 1 x1 y1 x2 y2 1 1 1 1 Description Drawing color (0: White, 1-255: Black). Left bounds. Top Bounds.
Parameters Description Parameter refID type x1 y1 x2 y2 Length 1 1 1 1 1 1 Description Reference number Type of bar graph. Left bounds. Top Bounds. Right Bounds. Bottom Bounds. This command initializes a bar graph referred to by number [reference number] of type [type] with size from (x1,y1) (top left) to (x2,y2) (bottom right).
Description Once the bar graph has been initialized it can be filled in using this command. This command sets the bar graph specified by the [ref] number to fill in [value]. [value] is given in pixels and should not exceed the available height/width of the graph. (If it does the graph will simply be written to its maximum size.) Remembered No 8.
Description A strip chart is an area of the screen reserved for horizontal scrolling. This is normally used as follows: • Initialize the strip chart, which reserves the appropriate area of the screen. • Draw a line segment at the right or left side of the strip chart. • Shift the strip chart to the right or left. • Draw the next line segment. • Used this way the strip chart can produce a graph which scrolls smoothly horizontally in either direction. With text the strip chart can produce a marquis effect.
Description This command shifts the strip chart left or right. [ref] determines both which strip chart is used and which direction it will shift. The direction is selected by the most significant bit (MSB): • MSB: 0 shifts left • MSB: 1 shifts right For example if [ref] is 1: • 254 107 1 (hex FE 6B 01) shifts left • 254 107 129 (hex FE 6B 81) shifts right This command shifts the contents of the area defined in the Initialize Strip Chart command 8 pixels at a time. Remembered No 9 Keypad 9.
9.3 Auto Transmit Key Presses Off Syntax Hexadecimal Decimal ASCII 0xFE 0x4F 254 79 254 “O” Description In this mode, up to 10 key presses are buffered until the unit is polled by the host system, via the poll keypad command 254 38. Issuing this command places the unit in polled mode. Remembered Yes 9.4 Poll Key Press Syntax Hexadecimal Decimal ASCII 0xFE 0x26 254 38 254 “&” Description This command returns any buffered key presses via the RS-232 interface.
Description This command clears any unread key presses. In a menu application, if the user presses a key which changes the menu context, any following key presses may be inaccurate and can be cleared out of the buffer between menu changes to prevent jumping around the menu tree. It may also be used, in effect, to reset the keypad in case the host application resets for whatever reason. Remembered No 9.
Parameters Description Parameter mode Length 1 Description Auto Repeat Mode (0: Resend Key , 1: Key Up/Down) Two auto repeat modes are available and are set via the same command: • Resend Key Mode: 0x00 • Key Up/Down Mode: 0x01 Resend Key Mode This mode is similar to the action of a keyboard on a PC. In this mode, when a key is held down, the key code is transmitted immediately followed by a 1/2 second delay.
Remembered No 9.9 Assign Keypad Codes Syntax Hexadecimal Decimal Parameters Parameter KDown KUp Description Length 25 25 Description Key down codes Key up codes This command will allow you to reassign the key codes that correspond to the key presses on the matrix style key pad. The first twenty-five bytes that are transmitted will be used for the key down codes and the next twenty-five bytes that are transmitted will be used for the key up codes.
10.2 Clear Screen Hexadecimal Decimal ASCII Syntax 0xFE 0x58 254 88 254 “X” Description This command clears the display and resets the text insertion position to the top left position of the screen defined in the font metrics. Remembered No 10.3 Backlight On Syntax Hexadecimal Decimal ASCII Parameters Parameter min 0xFE 0x42 [min] 254 66 [min] 254 “B” [min] Length 1 Description Minutes before turning the backlight on (0 to 90).
10.4 Backlight Off Syntax Hexadecimal Decimal ASCII 0xFE 0x46 254 70 254 “F” Description This command turns the backlight off immediately. The backlight will remain off until a ’Backlight On’ command has been received. Remembered Yes 10.5 Set Backlight Brightness Syntax Hexadecimal Decimal Parameters Parameter brightness 0xFE 0x99 [brightness] 254 153 [brightness] Length 1 Description Backlight setting (0 to 255). Description This command sets the backlight settings according to [backlight].
Description This command sets and saves the backlight [brightness] as default. Remembered Always 10.7 Set Contrast Syntax Hexadecimal Decimal ASCII Parameters Parameter contrast 0xFE 0x50 [contrast] 254 80 [contrast] 254 “P” [contrast] Length 1 Description Contrast value (0 to 255). Description This command sets the display’s contrast to [contrast], where [contrast] is a value between 0x00 and 0xFF (between 0 to 255).
Description This command sets the display’s contrast to [contrast], where [contrast] is a value between 0x00 and 0xFF (between 0 to 255). Lower values cause ‘on’ elements in the display area to appear lighter, while higher values cause ‘on’ elements to appear darker. Lighting conditions will affect the actual value used for optimal viewing. Individual display modules will also differ slightly from each other in appearance.
The last part of uploading a font file is to upload the file data. After transmitting each byte of the file the module will echo the byte and wait for a confirmation byte of 0x01 until the file has completed uploading. Below is an example of uploading the font file which we created in Section 5.1.2 on page 19.
11.2 Wipe Filesystem Syntax Hexadecimal Decimal ASCII 0xFE 0x21 0x59 0x21 254 33 89 33 254 “!” “Y” “!” Description This command completely erases the display’s non-volatile memory. It removes all fonts, font metrics, bitmaps, and settings (current font, cursor position, communication speed, etc.). It is an “odd” command in that it is three bytes in length in order to prevent accidental execution. Remembered Yes 11.
Description This command will return 4 bytes, LSB to MSB for how many bytes are remaining in the 16 KB on board memory. Remembered No 11.5 Get Filesystem Contents Syntax Description Hexadecimal Decimal This command will return the contents of the file system directory. The first byte returned will be a hex value representing the number of entries in the filesystem, followed by four bytes for each entry.
Parameters Parameter Type refID Length 1 1 Description File type (0:Font File, 1:Bitmap) Reference ID number Description Download a specified file from the filesystem. The first 4 bytes will be the length of the file (LSB to MSB) followed by the data contained in the file. Remembered No 11.
12.2 Set Remember Syntax Hexadecimal Decimal Parameters Parameter switch Description 0xFE 0x93 [switch] 254 147 [switch] Length 1 Description 0: Do not remember, 1: Remember This command allows you to switch the remember function on and off. To use the remember function, set remember to on, then set all of the settings that you wish to save, settings that are listed as ’Remember: Yes’ support being saved into the non-volatile memory.
Description Data lock, originally known as paranoia, allows you to lock the module from displaying information, as well as enables the protection of the filesystem and module settings.
12.4 Set and Save Data Lock Syntax Hexadecimal Decimal Parameters Parameter level 0xFE 0xCB [level] 254 203 [level] Length 1 Description Sets the data lock level Description This command will set and save the data lock level.
