FUNCTIONAL DESCRIPTION

COMMANDS

A command is the first byte (b0 to b7) inputted to TM1628 via the DIN

Pin after STB Pin has changed from HIGH to LOW State. If for some reason

the STB Pin is set to 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

TM1628 provides 2 display mode settings as shown in the diagram

below: As stated earlier a command is the first one byte (b0 to b7)

transmitted to TM1628 via the DIN Pin when STB is LOW. However, for

these commands, the bit 3 to bit 6 (b2 to b5) are ignored, bit 7 & bit 8 (b6 to

b7) are given a value of 0.

The Display Mode Setting Commands determine the number of

segments and grids to be used (12 to 11 segments, 6 to 7 grids). 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 , 11-segment modes

is selected.
