STEVAL-ILL024V1 and STEVAL-ILL025V1 demonstration boards
based on the STP16DP05 LED matrix driver and STM32F103VB
Introduction
This user manual describes the operation of the STM32F103VB-based LED matrix display
demonstration board. This board demonstrates the capability of the STP16DP05 LED driver
to drive the matrix LED panel. The complete system includes one master board, one slave
board and LED matrix display panels. The master and slave boards are STM32F103VB
microcontroller-based control units which are used for configuring the display settings for the
STP16DP05 display driver. This unit has a GPS module interfaced through a USART port.
The GPS data can be displayed with information on latitude and longitude and also a real-
time clock. The display can be configured for any of the nine different display modes and
nine different speeds using a PS2 keyboard. Display panels can also be configured through
the HyperTerminal using the serial interface present on the control units. The system also
consists of audio-out for playing back the .wav file pre-recorded in the microSD card
