How do I write into my Font Table using the GPP Interface?

解决方案

Here is an example of writing the character A for a font with a 1 bit color depth.


Character A:


This 8x8 font would be written in as the 32 bit words below. 

(This is based on an example in Table D-12, page 106 of the OSD Product Guide PG010).

gcdata = 0x663C1800
gcdata = 0x00667E66

Here is how this extends to the writing of the 16x16 font table.

Character A:


This 16x16 Font would be written in as 32 bit words:

gcdata = 0x01800000
gcdata = 0x07E003C0
gcdata = 0x1C380E70
gcdata = 0x700E381C
gcdata = 0x700E700E
gcdata = 0x7FFE7FFE
gcdata = 0x700E700E
gcdata = 0x0000700E
