Graphical display panel
demonstration board based on the STM32F103VE
Introduction
The STM32-based graphical display panel is a device that displays images one by one as in
a slideshow. The core of this demonstration board is the STM32 microcontroller which is
able to read the memory card of the photographs and display them on the screen. The
memory used to store the JPEG images is a micro-SD card. The MEMS is used for picture
orientation. The growing popularity and use of digital cameras and cell phones with high-
pixel cameras allow users to view digital photos in storage media without printing. Digital
photo frames are the perfect example of enjoying these digital images. The functionality of
displaying images with the STM32 shows the capability of this microcontroller in multimedia
applications. The STM32 has additional features like displaying room temperature, date and
time. An S-Touch
™
based keypad for user interface is also on the board. Other features
include USB mass storage, ZigBee
®
, and a rechargeable battery system. This board can be
used either as a standalone solution or combined with an application (i.e. POS, card
readers, security panels, USB speakers, high-end remote controllers).

This document explains the implementation of a digital photo frame using the STM32, an
ARM Cortex-M3 based microcontroller, and explains the different parts of the application.
The demonstration board is the STEVAL-CCM001V2.
