The last two instructions allow you to write to specific locations in the LCD’s memory. By
setting the display data (DD) RAM address, you can control the location on the display at
which subsequent characters will appear. This lets you update part of the display without
having to reprint the entire screen.
By entering values into character- generator (CG) RAM, you can define character patterns to
create simple graphics. The following figure shows how to calculate the data for these
patterns.
To define one of the 8 characters in CG RAM, put the LCD into Instruction mode, then send
the following value to the LCD: 64+ (8 x character_no.) where character_no. is in the range 0
to 7. Then send the bit-map data calculated as shown above. For example to define CG
RAM 3 with the above character send the following byte string:
[254, 88,0,4,14,31,14,4,0,0] where 88 is calculated from 64+3 x 8 = 88.
To print this character at the 4
[254,132] - 254 to put into instruction mode and move the cursor to 128 (start of line 1) +4= 132
