sub procedure SPI_Glcd_Set_Font(dim activeFont as longint, dim
aFontWidth 

as byte, dim aFontHeight as byte, dim aFontOffs as word)

Nothing.

Sets font that will be used with SPI_Glcd_Write_Char and SPI_Glcd_Write_Text
routines.

Parameters : 

- 

activeFont:

font to be set. Needs to be formatted as an array of char 

- 

aFontWidth:

width of the font characters in dots. 

- 

aFontHeight:

height of the font characters in dots. 

- 

aFontOffs:

number that represents difference between the mikroBasic PRO  

character set and regular ASCII set (eg. if 'A' is 65 in ASCII character, and 'A' 
is 45 in the mikroBasic PRO character set, aFontOffs is 20). Demo fonts 
supplied with the library have an offset of 32, which means that they start with 
space. 

The user can use fonts given in the file “__Lib_GLCD_fonts.mbas” file located in
the Uses folder or create his own fonts.

Glcd needs to be initialized for SPI communication, see SPI_Glcd_Init routines.

' Use the custom 5x7 font "myfont" which starts with space (32):
SPI_Glcd_Set_Font(@myfont, 5, 7, 32)
