Figure 18: Protocol Select Jumpers for Serial and I2 C modules Figure 19: Protocol Jumpers for USB modules 2.7 Filesystem Lock Jumper The Filesystem Lock Jumper allows you to lock the filesystem on the GLT240128 so that no fonts or bitmaps can be either written or deleted from the on board memory.
Figure 20: Filesystem Lock Jumper 2.8 Manual Override The Manual Override is provided to allow the GLT240128 to be reset to some of the factory defaults. This can be particularly helpful if the display module has been set to an unknown baud rate or I2 C 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, as pictured below. Power up the display module.
Table 1: Default Values Contrast 128 Backlight 255 Baud Rate 19.2 kbps Data Lock False NOTE The display module will revert back to the old settings once turned off, unless the settings are saved. 3 Troubleshooting 3.1 The display does not turn on when power is applied. • First, you will want to make sure that you are using the correct power connector.
3.3 The display module is communicating, however text cannot be displayed. • The cause of this is often that no font has been loaded onto the display. To load a font onto the display see Section 4.2.1 on page 16. • Another common cause may be that the contrast settings have been set to low.
bit, a 0 designates a write address and a 1 designates a read address. The default read address of the display module will be 0x51, whereas the write address is 0x50 by default. This address may be changed by using cmd 254 / 51 /
. The GLT24064 should only be sent addresses that are even (LSB is 0). When the I2 C master wishes to write to the display, the effective address is $50 (0101 0000) , since the LSB has to be 0 for an I2 C master write.Table 2: I2 C Transaction Algorithm START Toggle SDA high to low Address 0x50 Information 0x48 0x45 0x4C 0x4C 0x4F STOP Toggle SDA low to high 4.1.3 Serial Communication In addition to being able to communicate via I2 C the GLT24064 communicates natively through the RS-232 protocol at at a default baud rate of 19,200 bps and is capable of standard baud rates from 9600 to 115,200 bps.
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. When the buffer empties so that only [empty] bytes remain, the display will return an “almost empty” message (0xFF) to the host controller. The display will return the “almost full” message for every byte sent to the display until the used buffer space once more drops below the [full] level.
Syntax Parameters Description Hexadecimal Decimal ASCII Parameter adr 0xFE 0x33 [adr] 254 51 [adr] 254 “3” [adr] Length Description 1 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. For example if the I2 C write address is set to 0x50, then the read address is 0x51. NOTE The change in address is immediate. Remembered Default 4.
4.6 Setting a Non-Standard Baud Rate Syntax Parameters Description Remembered Examples Hexadecimal Decimal Parameter speed 0xFE 0xA4 [speed] 254 164 [speed] Length Description 2 Inputed LSB MSB from baud rate formula (12-2047). 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 CrystalSpeed modules baud generator. Use the formula, speed = 8×DesiredBaud − 1 to calculate the [speed] for any baud rate setting.
5 Fonts 5.1 Introduction The GLT24064 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 5. 5.1.1 Font File Format A font file consists of three parts, a header, a character table and bitmap data. 1.
Nominal Width 0x05 Table 8: Font File Header Height ASCII Start Val 0x07 0x68 ASCII End Val 0x6A Next we will have to find out how many bytes each character will use up, in order to create the character table.
Once completed, place the character table after the header and the character data aat the end, as seen in table 10. 0x05 0x12 0xC6 0x60 0x07 0x03 0x20 Table 10: Sample Font File 0x68 0x6A 0x00 0x0D 0x00 0x15 0x04 0x84 0x43 0x24 0x84 0x2D 0x05 0x2D 0x98 0x00 0x98 0x19 Red = Header Blue = Character Table Purple = Character Data 5.
Parameters Description Remembered 5.4 Parameter refID Length 1 Description A unique font identification number. In order to set the font on the GLT24064 you must know the font identification number of the font that you wish to use. The font ID is established when the font is saved to the display. The default installed fonts are “Small Filled” and “Futura Bk BT 16” and their font ID’s are 0x01 and 0x02 respectfully, with “Small Filled” being the default selected font.

11.1.2 XModem Upload Protocol In addition to its original simple upload format, Matrix Orbital has added an XModem based protocol. This facilitates much faster download speeds by increasing the packet size from 1 byte to 128 bytes greatly increasing throughput. A two byte CRC check is preformed at the end of each packet in place of the byte echo system seen in the original protocol. However, the overall protocol remains much the same as the original, but much faster.
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. NOTE After deleting the file system it is important to cycle power to your display to ensure the removal process is completed. Remembered Yes 11.
