FUNCTIONAL DESCRIPTION
Commands
A command is the first byte (b0 to b7) inputted to IK2102 via DI/O 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: DISPLAY MODE SETTING COMMANDS
IK2102 provides 4 display modes setting as shown in the diagram below: As stated earlier
a command is the first one byte (b0 to b7) transmitted to IK2102 via the DIN, DI/O Pin
when STB is “LOW”. However, for these commands, Bit 3 & Bit 8 (b2 to b7) are given a
value of “0”.
The Display Mode Setting Commands determine the number of segments and grids be
used (4 grids to13 segments, 7 grids to 10 segments). 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 mode 11 is selected.
Display Mode Settings:
00: 4 Grids, (13 Segments)
01: 5 Grids, (12 Segments)
10: 6 Grids, (11 Segments)
11: 7 Grids, (10 Segments)
COMMAND 2: DATA SETTING COMMANDS
The Data Setting Commands executes the Data Write Mode for IK2102. The Data Setting
Command, the bits5 and 6 (b4, b5) are given the value of “0”. , bit7 (b6) is given the value
of “1” while bit8 (b7) is given the value of “0”. Please refer to the diagram below.
When power is turned ON, bit 4 to bit 1 (b3 to b0) are given the value of “0”.
