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 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
