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.

corresponding to the font. A directory listing of the contents of the
entire filesystem may be obtained by using the “Get Filesystem
