Selection of display pattern

The system has been provided with the 4 different display pattern options. These display

patterns explain the capability of the device STLED316S to control the various digits and

segments independently.

The 4 display pattern options are:

●

constant display - constant BAR

●

variable display - constant BAR

●

constant display - variable bar

●

variable display - variable bar

Any of the display patterns can be selected using the 'MENU' and 'OK' keys of the front

panel (see Section 3.5 and 3.7).

2.4

DEMO mode

To make the system user independent a 'DEMO' mode has been provided. The system can

be put into the DEMO mode by pressing the 'DEMO' key of the front panel. In this mode all

the display patterns and the welcome message are displayed in continuous loop. The

system can be made to exit the DEMO mode by pressing the 'OK' key (see Section 3.6 and

3.7).

Note:

When the system is in DEMO mode, all other keys except 'OK' and 'RESET' are disabled.

On the press of any key (except RESET) of the front panel board, the IRQ LED (RED) blinks

once indicating that a key has been pressed.
