Description In order to set the font on the 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 41 for more detailed
