Matrix Orbital GLT240128 Legacy - Manual (Page 30)

Parameters Parameter Length Description
refID 1 A unique font identification
number.
Description 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.
Once you are aware of the font ID for the font that you wish you use,
simply send the command bytes (0xFE 0x31) and then send the font ID
corresponding to the font. A directory listing of the contents of the
entire filesystem may be obtained by using the “Get Filesystem
Directory” command, see Section 11.5 on page 48 for more detailed
information.

5.4 Font Metrics
Syntax Hexadecimal 0xFE 0x32 [lm] [tm] [csp] [lsp] [srow]
Decimal 254 50 [lm] [tm] [csp] [lsp] [srow]
ASCII 254 “2” [lm] [tm] [csp] [lsp] [srow]
Parameters Parameter Length Description
lm 1 Left margin: Location in pixels.
tm 1 Top margin: Location in pixels.
csp 1 Character Spacing: Amount of
space in pixels between characters.
lsp 1 Line Spacing: Amount of space
between lines in pixels.
srow 1 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. [lm] defines the leftmost position
and [tm] the topmost. [csp] controls the amount of pixels that are placed
in between characters and [lsp] controls the amount of pixels that are
placed in between lines. [srow] is the location of the top of the last row
that will be displayed on the GLT24064. It defines the row that, when
filled, will cause the display to auto scroll if auto scrolling is enabled.
The font metrics will have to be reconfigured after changing to a
different font.
