Embedded Ethernet web client based on the STR91x
Introduction
This document describes the functioning of the STEVAL-PCC008V1 demonstration board
with an embedded Ethernet web client system which is based on ST's STR91xFAW
ARM966E-S™ 16/32-bit Flash MCU with Ethernet microcontroller. This system is designed
for viewing/monitoring jpeg images taken from an HTTP web server or from an IP camera
present on the network. The images are displayed on the TFT present on the board, thus
enabling surveillance. This system needs to be plugged into the network to access jpeg
images from the HTTP web server or from the IP camera. This system is compatible with
web servers which do not require support for secure socket layer (SSL) and it uses specific
programmed requests to capture images from specific web servers.
The system uses a 2.4" TFT for displaying the images captured from the network. The
captured jpeg images are displayed on the TFT by converting them into bitmap through a
jpeg decompression algorithm. A six-button keypad is provided for navigating through the
menus. The availability of the micro-SD card on the board helps in handling large quantities
of data from the network.

UM0897 Getting started These images should be given names as advised below: Name the images starting from 31.jpeg, 32.jpeg, …… 60.jpeg. In network mode, the demonstration unit requests these images one by one. If the user wishes to add one file (for example IMAGE.jpeg), first delete any file from the list (for example 40.jpeg), then rename IMAGE.jpeg to 40.jpeg which allows the user to display that image on the TFT. -
