Selecting the control unit as master or slave
Any control unit can act as the master or slave. The on-board keypad is used to configure
the control unit as master or as slave.
The steps for configuring the control unit are listed below:
Description of the STEVAL-ILL025V1 LED driver-based
display unit
The STEVAL-ILL025V1 display unit is an STP16DP05 LED display driver-based panel.
Each display panel has four STP16DP05 LED display drivers, two buffers, eight Darlington
pairs and a matrix of 16 x 32 LEDs. Each panel can be connected in series to create a larger
display. Series connection between the display panels is done through a 10 x 2 header. A
20-pin flat-ribbon cable is used to connect the two display panels. Input to the display panel
comes from the control unit through the 20-pin flat-ribbon cable. Therefore, the first display

The LCD shows “Press “#” to enter Configuration Mod”, for 4 seconds
Press “#” on the keypad present on the board. The LCD shows “Master Sel: Entr
*1” and “Slave Sel: Entr *2”
To configure the board as the master, press “*1” or to configure the board as the
slave press “*2” on the keypad
If “*1” is pressed, then the LCD shows “Master Board” for 2 seconds and then
starts the master routine on the board
If “*2” is pressed, then the LCD shows “Slave Board” for 2 seconds and then starts
the slave routine on the board.
On the next power-up of the board the message “Press “#” to enter Configuration
Mod” is again shown on the LCD for 4 seconds, but if “#” is not pressed within 4
seconds, the board enters into the last configured mode.
