TECHNICAL DATA
KK1207
FUNCTIONAL DESCRIPTION
Commands
A command is the first byte (b0 to b7) inputted to KK1207 via DIN Pin after STB Pin has changed from
”HIGH” to “LOW” state. If for some reason the STB Pin is set “HIGH” while data or commands are
being transmitted, the serial communication is initialized, and the data/commands being transmitted are
considered invalid.
COMMAND 1 : DISPLAYMODE SETTING COMMANDS
KK1207 provides 4 display mode setting as shown in the diagram below: As stated earlier a
command is the first one byte(b0 to b7) transmitted to KK1207 via the DIN Pin when STB is
“LOW”. However, for these commands, Bit No.3 to Bit No.6(b2 to b5) are ignored,
Bit No.7 & Bit No.8(b6 to b7) are given a value of “0”.
The Display Mode Setting Commands determine the number of segments and grids be used
(1/4 to 1/7 duty, 12 to 9 segments). When these commands are executed, the display forcibly
turned off. A display command “ON” must be executed in order to resume display. If the same
mode setting is selected, no command execution is take place, therefore, nothing happens.
When Power is turned “ON”, the 7-Grid, 9-Segment Mode is selected.
