How to Load Information Into the Display
Information loaded into the display can be either ASCII data or
Control Word data. The following procedure (see also Typical
Loading Sequence) will demonstrate a typical loading sequence
and the resulting visual display. The word STOP is used in all of
the following examples.
Set Brightness
Step 1 Set the brightness level of the entire display to your
preference (example: 100%)
Load Four Characters
Step 2 Load an Sin the left hand digit.
Step 3 Load a Tin the next digit.
Step 4 Load an Oin the next digit.
Step 5 Load a Pin the right hand digit.
If you loaded the information correctly, the display
now should show the word STOP.
Blink a Single Character
Step 6
Into the digit, second from the right, load the hex
code CF,which is the code for an Owith the
D7 bit added as a control bit.
Note:
The Ois the only digit which has the control bit (D7)
added to normal ASCII data.
Step 7
Step 8
Step 9
Step 10
Load enable blinking character into the control
word register. The display should show STOP
with a ashing O.
Add Another Blinking Character
Into the left hand digit, load the hex code D3
which gives an Swith the D7 bit added as a
control bit. The display should show STOP
with ashing Oand a ashing S.
Alternate Character/Cursor Enable
Load enable alternate character/cursor into the
control word register. The display now should show
STOPwith the Oand the Salternating
between the letter and cursor (all dots lit).
Initiate Four Character Blinking
(Regardless of Control Bit setting)
Load enable display blinking. The display now
should show the entire word STOPblinking.
