14. Interface with LCD and the Character Extension IC (MSM5259)
Display examples when setting the 5
￥
7 dots character font 1-line mode (Figure 1), 5
￥
10 dots
character font 1-line mode (Figure 2), and 5
￥
7 dots character font 2-line mode (Figs. 3 and 4)
through instructions are shown below.
When the 5
￥
7 dots character font is set in the 1-line display mode, COM
9
to COM
16
output the
COM signals for turning the display off.
Likewise, when the 5
￥
10 dots character font is set in the 1-line display mode, COM
12
to COM
16
output the COM signals for turning the display off.
The display examples show 20 characters (40 characters in Figure 3, 32 characters in Figure 4).
When the number of MSM5259s are increased according to the increase in the number of
characters, it is possible to display a maximum of 80 characters.
The bias voltage required to operate the LCD is made by a bias dividing resistor built in the
MSM6562B-xx and this voltage must be input to the MSM5259.
These bias examples are shown in Figures 5, 6, 7 and 8 and there are following two ways for
adjusting the bias voltage.
As shown in Figures 5 and 6, this method divides the bias by installing VR to V
5
. On the other
hand, as shown in Figures 7 and 8, this uses the built-in contrast adjusting circuit by connecting
V
5
and V
5
'.
Figure 9 shows the connection of the MSM6562B-xx and the MSM5259 including the bias circuit.
(The example shows the display of 40 characters and 2 lines using the built-in contrast adjusting
circuit.)
In addition, the bias voltage must keep the potential relation of V
