16.5.2.2. Graph display
To present two overlaid graphs on the screen, configure
the display as for the menu bar display and put one graph
on each screen layer. The difference in contrast between
the half- and full-intensity displays will make it easy to
distinguish between the two graphs and help create an
attractive display.
1. OVLAY: P1 = 00H
2. DISP ON/OFF: P1 = 34H
16.5.3. Flashing areas
16.5.3.1 Small area
To flash selected characters, the MPU can alternately
write the characters as character codes and blank charac-
ters at intervals of 0.5 to 1.0 seconds.
16.5.3.2. Large area
Divide both layer 1 and layer 2 into two screen blocks
each, layer 2 being divided into the area to be flashed and
the remainder of the screen. Flash the layer 2 screen
block at 2 Hz for the area to be flashed and combine the
layers using the OR function.
16.6. 16
× 16-dot Graphic Display
16.6.1. Command usage
This example shows how to display 16
× 16-pixel
characters. The command sequence is as follows:
CSRW
Set the cursor address.
CSRDIR
Set the cursor auto-increment direction.
MWRITE Write to the display memory.
16.6.2. Kanji character display
The program for writing large characters operates as
follows:
1. The microprocessor reads the character data from its
ROM.
2. The microprocessor sets the display address and
writes to the VRAM. The flowchart is shown in
Figure 69.
