6-11-3 Create Symbol
RA8806 provides font creator function that allows user to design and create new fonts, special
symbols or logos and store into its embedded CGRAM or DDRAM. The user-created characters
each defined as a full-size (16x16) or half-size (8x16) character bitmap font formats, thus 24x16,
40x16, 16x32 or bigger sized fonts are also possible to create accordingly. The following Figure
6-56 represents a user created symbol with size 24x16.
For creating a new symbol, in addition to write command to CGRAM or DDRAM, note the setting of
the font codes before trying to write characters to be displayed. See the following 2 examples of
creating this 24x16 symbol in DDRAM:
