2 ZigBee smartplug
2.1 Smartplug description
The smartplug coordinator is connected via an SPI to the STM3210C-EVAL through an “Ad-
Hoc” adapter.
In Figure 1 it is possible to take a quick look at the STM3210C-EVAL board and a smartplug
node block diagram.
Figure 1. STM3210C-EVAL block scheme
An adapter is connected to the extended connectors CN8 and CN9 on the STM3210C-
EVAL (for more detailed information please refer to the UM0600 user manual), it allows the
connection of a ZigBee smartplug coordinator and the I2C/RF dual interface EEPROM
M24LR64-r. The Gerber files of the adapter board are included in the setup package of this
project.
The ZigBee smartplug board can be used as a guide to build a home/building automation
subsystem for energy management. In a typical application, the board is plugged into an
electrical wall socket and supplies an electrical load, monitoring the energy consumption;
using several smartplugs it is possible to monitor and control the home/building energy
consumption socket by socket. The board includes the following functions, shown in the
block diagram of Figure 2:
●Energy measurement
●Load differential current
●Load driving by relay or TRIAC (dimming)
●ZigBee communication capability.

Figure 2. Block diagram
The STEVAL-IHP001V3 is a smartplug board based on an STM32F10x microcontroller, a
SPZB260 ZigBee module, and an STPM01 energy metering IC.
It implements a ZigBee metering node which allows the final user to monitor and manage
energy consumption.
The board has been developed as a guide to build a home/building automation subsystem
for energy management. In a typical home system implementation, the board is plugged into
an electrical wall socket and supplies a home appliance or other generic electrical load.
The current, power, energy, and other information, related to the electrical load connected to
the smartplug board, can be displayed locally on an LCD screen, and are sent to a ZigBee
data concentrator through the home/building ZigBee network.
2.2 ZigBee module
ZigBee smartplug communication is based on the SPZB260 module with a DIL adapter. The
module is FCC compliant (FCC ID:S9NZB260A). The module is based on the SN260
ZigBee network processor which integrates a 2.4 GHz, IEEE 802.15.4 compliant
transceiver, as well as IEEE 802.15.4 PHY and MAC. The main features are:
●0dBm nominal TX output power
●-92dBm RX sensitivity
●+2dBm TX output power in boost mode
●RX filtering for co-existence with IEEE 802.11g and Bluetooth®devices.
For further details please refer to the SPZB260 module and the SN260 network processor
datasheet.

AN3311 Multi-input embedded GUI library

3 Multi-input embedded GUI library
3.1 Description
This solution enables users, comfortable with the use of standard microcontrollers, to create
higher-end “look and feel” human interfaces by replacing conventional electromechanical
switches with touch-sensing controls.
Users can combine touch-sensing functions using multiple configurations (touchscreen,
joystick, and keys) with traditional MCU features (communication, beeper, LCD control, etc.).
The E-multi-input graphic library is part of the application firmware.
The graphic objects are a set of controls that can be printed on the screen and associated to
an action when pressed.
The library has been developed and tested on an LCD panel of QWGA resolution (320x240)
which is the default, but the library is independent of the LCD resolution, although it has not
been tested with others.
The library supports touchscreen features and includes a low level driver which handles the
analog input (for 12-bit ADC), and a function for the touchscreen calibration based on an
algorithm that uses 5 points.
The multi-input embedded GUI firmware library is fully developed in 'ANSI-C' following an
OOP approach. This means that the final application uses instances of page and graphic
objects according to their public methods and properties. In the end, the PageObj is a
structure containing public properties (data fields) and methods (functions pointers). The
OOP encapsulation feature is assured. The library has been developed and tested on the
“STM3210C” STMicroelectronics demonstration board.
The library can be included in the final application as a library file (multi-input embedded
GUI library.a) and used as a black box through its exported public API, or can be included in
the final application as source files (.c and .h), if the user wants to debug the library itself, or
to change the HAL functions in order to port the library on a different LCD (in model and
resolution) from the one attached to STM3210C-EVAL.
For more information on the graphic library see the AN3128, rev. 2, application note.
The calibration process is part of the post-processing layer. The touchscreen must be
calibrated at first power-on and/or upon user request.
Once the calibration is done, final adjustments on future power-on of the board are not
necessary because the calibration parameters are saved on the Flash memory.
The touchscreen and the joystick are controlled by the STMPE811 devices.
The STMPE811 has a simple 2-wire I2C digital serial interface which allows the user to
access the data in the touchscreen controller register at any time. It communicates via the
serial interface with a master controller.
Figure 3 shows how the STM32F10xxx microcontroller (master device) must be connected
to the STMPE811 device.
Refer to the STMPE811 datasheet for more information on the register concerning the data
of the touched points on the touchscreen.

4.13 Daughterboard extension connector CN8 and CN9
Two 50-pin male headers, CN8 and CN9, can be used to connect a daughterboard or
standard wrapping board to the STM3210C-EVAL demonstration board. All 80 GPIOs are
available on it. The space between these two connectors and the power position, GND and
RESET pin are defined as a standard, which allows to develop common daughterboards for
several demonstration boards. The standard width between CN8 pin1 and CN9 pin1 is 2700
mills (68.58mm). This standard was implemented on the majority of demonstration boards.
Each pin on CN8 and CN9 can be used by a daughterboard after disconnecting it from the
corresponding function block on the STM3210C-EVAL demonstration board.
