16-DIGIT 5X7-SEGMENT VFD CONTROLLER
3. Character display
A character (refer to the character code table) which corre-
sponds to the character code transmitted from the MCU is
displayed as the designated digit.
The display digit is designated by the display digit setting
command. In case that the display digit designated by this
command is set to increase automatically, the display digit is
automatically increased by 1. After a character is displayed to
the most significant digit, it is displayed to the least significant
digit.
When the auto increment setting is canceled, the display digit
is fixed.
Ex. In order to display a character A to digits 14, 15, 16, 1 and 2 in this order
and characters A, B and C to digit 8 successively, 12-byte data must be
transmitted in the following order.
(Display digit length = 16)
A (code 41
16
)
B (code 42
16
)
C (code 43
16
)
OPERATION AT RESET
When a reset signal is input, the internal state is initialized as
shown in Table 4.

4. All-digit display ON/OFF
All digits are simultaneously lighted or put off by inputting all-
digit display ON command or all-digit display OFF command.
When all-digit display ON command is transmitted, all digits
including a cursor and all segments are lighted.
Therefore, this command can be used for the lamp test.
When all-digit display ON setting is canceled (normal opera-
tion mode is selected), all digits are displayed according to
the setting before all-digit display ON operation. It is also
possible to set the next character to the designated digit dur-
ing the all-digit display ON operation.
When all-digit display OFF command is transmitted, all digits
including a cursor are put off. When all-digit display OFF set-
ting is canceled (normal operation mode is selected), all dig-
its are displayed according to the setting before all-digit
display OFF operation. It is also possible to set the next char-
acter to the designated digit in the all-digit display OFF state.
