STEVAL-CDE001V1 Embedded web server based on the ST72F321M9 microcontroller Data Brief Features Provides temperature measurements in the range of -55 C to 150 C Ethernet interface to the webpage based temperature display on computer terminal 2x16 dot matrix interface LCD module Switches are provided for user interface 10 pin ICC programming/debugging connector SCI interface for testing purposes 1 Mbyte serial Flash for storage of webpages having larger memory requirements Description This evaluation board is able to offers a temperature display via LCD on the board and on STEVAL-CDE001V1 a webpage via Ethernet connection. The board acts as a server to provide temperature information on a webpage displayed on the client end. Is also able to measure the temperature from a remote region and send it to a computer unit and then provides the solution for central server- based temperature measurement of various terminals as in applications such us air conditioning control in the industrial sector and hospitals.
