Parameters
Parameter Length Description
refID 1 A unique font identification
number.
Description In order to set the font on the GLK19264-7T-1U 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 12.5 on page 49 for more detailed
information.
