ST72321M9 embedded web server evaluation board
Introduction
This user manual describes the operation of the ST72321M9 embedded web server board.
(STEVAL-CDE001V1). The board offers temperature measurement via an on-board
temperature sensor and displays it on the web page of the client PC connected via an
Ethernet connection. In addition, there is an LCD available on the board for temperature
display. There is an embedded web server firmware running on the board. This system can
be used for remote monitoring solution for applications such as air conditioning control in
industry, hospitals, etc. The same concept can also be utilized for other applications
requiring web or Ethernet connectivity. The board has the following features:
■
Provides temperature measurements in the range of -55 °C to 150 °C
■
Ethernet-based temperature monitoring on a computer terminal
■
16*2 dot matrix interface LCD module
■
Switches are provided for user interface
■
10-pin ICC programming and debugging connector
■
Webpage is stored in internal flash of the microcontroller
The board operates on 5 V power supply. The board is comprised of the ST72F321M9 as
the controller, with operating voltage range of 3.8 V to 5.5 V, Flash 60 KB, and the LQFP80
14x14 package. The microcontroller senses the temperature of the environment through an
LM135 analog temperature sensor by using the analog-to-digital converter (ADC), and then
the resulting temperature value is sent to the web page and displayed in HTML format on
the computer terminal via the Ethernet hub. Since the temperature value is also available on
the LCD mounted on the board, this can be used in absence of a web interface such as a
front panel temperature display of a refrigerator, air conditioner, or any other home
appliance.

80-pin LQFP package. The hardware block diagram Figure 14 illustrates the connection
between the ST72F321M9 and peripherals (LCD, temperature sensor, Ethernet EEPROM,
serial Flash and debugging connector). Figure 15 will help you locate these features on the
actual web server board.

Power supply
The ST72321M9 embedded web sever board is designed to be powered by a 5 V DC power
supply through the power jack (J22) on the board.
U12 (KF33BD-TR) mounted on the board generates the 3.3 V DC power supply which
power(s) some parts of the board.
The power supply is configured by setting the related jumpers.

Features:
–
It is operated on a 20 MHZ clock
–
Supports 4 diagnostic LED pins with programmable outputs
Three LED's D1 (LED-LINK), D2(LED-RX), D3(LED-TX)) are available on the board.
2.14
RS232 level converter U6
The ST232ABDR is used to provide the voltage levels required for RS232 communication. It
has a supply voltage range of 4.5 to 5.5 V and a transmitter output voltage swing of ± 9 V.
2.15
Level shifter U10
ST2378ETTR is used to act as a ±15 kV ESD-protected level translator providing the level
shifting necessary to allow data transfer in a multi-voltage system. This is connected
between the serial flash and microcontroller since serial flash is operating on 3.3 V.
