In-Home Display with HTTP gateway

IntroductionIn this period of energy optimization and metering, there is an ever increasing demand for the possibility to perform in-house monitoring and management of energy use.

For this reason, STMicroelectronics offers a system which allows the monitoring and management of home energy consumption.

This system, “In-Home Display gateway”, is made up of three main components:

■ The STM322xG-EVAL demonstration board connected to an Ethernet network

■ The STEVAL-IDZ001V1 adapter board connected on top of the STM322xG-EVAL board

■ Remote web server.

Through this infrastructure, the system has the ability to publish the home automation device (i.e. smartplugs) energy data to a remote web server. The user can consult the energy consumption data on the web server from wherever they are, and at home, they can manage the entire system directly through an LCD touch panel.

This application note describes a smartplugW network system managed through the STM322xG-EVAL board.

The firmware and board allow the possibility to manage a ZigBee® network system, collecting ZigBee device information, and managing it through the LCD, touchscreen, pushbutton and joystick, and publishing the collected data to a HTTP server over the Internet by means of an Ethernet interface.

■ Section 1 describes the document and library rules.

■ Section 2 highlights the features of the ZigBee smartplug and explains its hardware interface with the microcontroller (STM32).

■ Section 3 describes briefly the “Multi-Input Embedded GUI Library”.

■ Section 4 describes the relevant blocks of the STM322xG-EVAL demonstration board.

■ Section 5 shows the demonstration firmware/board system setup.

■ Section 6 describes how the “In-Home Display” firmware is structured, its architecture and its exported APIs in detail.

■ Section 7 explains how to get started with the system, how to configure and use the IAR workspace, and it contains an example application source code.

■ Section 8 illustrates how the “In-Home Display” GUI application works.

■ Section 10 illustrates the hardware schematics.

2 System description

The network configuration parameters (IP address, subnet mask, and default gateway) of the board as well as the IP address of the web server are stored in the dual interface EEPROM “M24LR64r” onboard, accessible from both the STM32W108CB and the STM32F2x7x via the I2C interface and remotely by means of an RF reader. Therefore, it is possible to read and update parameters from inside (I²C) and outside (RF) the application. In this way, an operator can easily change the network configuration of the board without any programming skills, and using just an RF reader.

In order to use the STM322xG-EVAL board to interface with the ZigBee coordinator, a specific adapter has been developed. The ZigBee coordinator is connected to the demonstration board through the adapter that allows the UART communication. The two peers use a serial protocol to exchange data and commands.

The STM32W108CB is used as a co-processor of the STM32F2x7x, so the STM32F2x7x runs the application while the STM32W108CB runs the ZigBee stack and protocol. The two microcontrollers communicate by means of a UART interface.

An embedded graphical user interface (GUI) based on the “Multi-Input Embedded GUI Library 2.1" described in the document AN3128, and working on an LCD TFT 320 x 240 display and 5-position joystick, allows the user to interact with the smartplugW system made up of one coordinator and two smartplugs connected.

In Figure 1 it is possible to take a quick look of the STM322xG-EVAL board and a smartplug node block diagram.

3 ZigBee smartplug

3.1 Smartplug descriptionThe smartplug coordinator is connected via UART to the STM322xG-EVAL through an “ad-hoc” adapter. The adapter is connected to the extended connectors CN2, CN3 and CN4 on the STM322xG-EVAL (for more detailed information, please refer to the UM1065 user manual); it allows the connection of a ZigBee 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.

Figure 2. Block diagram

The STEVAL-IHP004V1 is a smartplug board based on an STM32W108CB microcontroller, a SPZB32W1x2.1 module, and an STPM10 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 to provide 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.

3.2 ZigBee module SPZB32W1x2.1ZigBee communication is based on the SPZB32W module. The SPZB32W is a low power consumption ZigBee module optimized for embedded applications. It enables OEMs to easily add wireless capability to electronic devices.

The module is FCC compliant (FCC ID: S9NZB32C2) and it is based on the STM32W108CB MCU which integrates a 2.4 GHz IEEE 802.15.4-compliant SMD module based on the ST single-chip STM32W108CB featuring:

● Integrated 2.4 GHz transceiver

● PHY and MAC IEEE 802.15.4 features

● Integrated ARM® Cortex-M3 core

● Integrated 128 kB embedded Flash and 8 kB embedded RAM

● Integrated encryption (AES-128) accelerator

● +3 dBm output power (+8 dBm in Boost mode)

● -99 dBm receiver sensitivity.

The module is controlled by means of a standard serial interface (SPI) allowing connection to a variety of host microcontrollers.

For further details, please refer to the SPZB32W module and the STM32W108CB datasheet.

Multi-Input Embedded GUI Library AN4049

10/81 Doc ID 022809 Rev 2

4 Multi-Input Embedded GUI Library

4.1 DescriptionThis 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.

The user can combine touch-sensing functions using multiple configurations (touchscreen, joystick, and keys) with traditional MCU features (communication, LED control, 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 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 STMicroelectronics demonstration boards.

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 if they want to change the HAL functions in order to port the library on a different LCD (in model and resolution) from the one attached to the ST demonstration board.

For more information on the graphic library, see the AN3128 rev.4 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.

5.10 Development and debug supportThe version 2 of the ST-LINK, called ST-LINK/V2, is embedded on the board. This tool allows onboard program loading and debugging of the STM32F using the JTAG or SWD interface.

Third-party debug tools are also supported by the JTAG (CN14) or trace (CN13) connectors.

To communicate with the embedded ST-LINK/V2, a specific driver needs to be installed on the PC. To download and install this driver, refer to the software and development tools page for the STM32F family available on www.st.com (the install shield is called ST-LINK_V2_USBdriver.exe).

The embedded ST-LINK/V2 connects to the PC via a standard USB cable from connector CN21. The bicolor LED LD10 (COM) indicates the status of the communication as follows:

● Slow blinking red/off: at power-on before USB initialization

● Fast blinking red/off: after the first correct communication between PC and ST-LINK/V2 (enumeration)

● Red LED on: when initialization between PC and ST-LINK/V2 is successfully finished

● Green LED on: after successful target communication initialization

● Blinking red/green: during communication with target

● Green on: communication finished and OK

● Orange on: communication failure.

Note: It is possible to power the board via CN21 (embedded ST-LINK/V2 USB connector) even if an external tool is connected to CN13 (trace) or CN14 (external JTAG and SWD).

5.11 Display and input devicesThe 3.2" TFT color LCD connected to the FSMC bus and 4 general purpose color LEDs (LED 1, 2, 3, 4) are available as display devices. A touchscreen connected to an I/O expander (U24), 4-direction joystick with selection key, general purpose button (B4), wakeup button (B2) and tamper detection button (B3) are available as input devices.

Doc ID 022809 Rev 2 47/81

7 Getting started with the system

7.1 Hardware requirements● ZigBee adapter board with the ZigBee module SPZB32W onboard

● STM322xG-EVAL board with the jumpers set as described in Section 7.2

● VDC / 2 A isolated power supply is recommended

● One JTAG programmer/debugger dongle (J-Link from SEGGER or IAR Systems™ is recommended). It is unnecessary if no modifications to the firmware code have been performed.

7.2 STM322xG-EVAL demonstration board setupSet up the STM322xG-EVAL board as follows:

● Keep jumper JP16, JP21 and JP22 not fitted

● Set JP5 in 1-2 position, and JP6 in 2-3 position

● Disconnect motor control board from CN5

● Remove MicroSD card from CN6

● Remove R115 and R140.

Set up the STEVAL-IDZ001V1 adapter as follows:

● Place the adapter on the STM322xG-EVAL board so that it is well fixed on connectors CN2, CN3 and CN4

● Set JP3 and JP4 in 1-2 position in order to set the communication between STM32W108CB and STM32F2x7x via UART

● Set JP1 and JP2 in position 1-2 to assign 0xA6 as I2C address for the dual interface EEPROM (M24LR64r).

7.3 STM322xG-EVAL and ZigBee adapter pins mappingThe connections between the MCU and the ZigBee module + EEPROM dual interface are shown in Table 12.

7.4 Program/update dual interface EEPROM with network parametersThe dual interface EEPROM M24LR64-r stores the network parameters of the STM322xG-EVAL board inside the first 3 blocks of the sector 1 and the IP address of the web server at the fourth block of the sector 1, where each block is 4 bytes. The schema is the following:

● Block 0000: IP address

● Block 0001: subnet mask

● Block 0002: default gateway

● Block 0003: web server IP address.

Figure 12 shows a screenshot of the “M24LRxx application software”, the GUI application that allows the user to program the M24LR64-r memory through an RF reader (i.e. FEIG) included in the demo kit (USB based) of the dual interface EEPROM:

7.5 Configure IAR tool for building, debugging, and programming applicationTogether with the firmware library package, an example application is delivered in order to provide the final user with a real example of the “In-Home Display with HTTP gateway” application usage.

The delivered example application has been written and developed using IAR EWARM 6.30 IDE and can be built for the STM32F2x7x microcontroller.

The workspace is created using the IAR embedded workbench 6.30 IDE, using the ARM®-based 32-bit STM32F2x7x firmware library (ver. 1.0.0), CMSIS compliant, and in C language.

The tree structure of the project is organized separating and grouping the source files with the header files, both for the project files and the library files, as shown in Figure 13.


50/81 Doc ID 022809 Rev 2

Figure 13. Application project files

In order to load the project, click on File\Open\Workspace and in the window that appears select, in \project folder\EWARM, the file “Project.eww”.

Figure 14. IAR embedded workbench main window

On the main node, where the program name located in the files window is shown, right click and select Options. In the window which appears, select the Debugger item in the Category list box, and select the proper debugging tool in the Driver list box, then press the OK button. In the proposed example the J-Link dongle is used (Figure 15).

Press the “Make” icon or click on “Project \ Rebuild All”. Any error or warning should appear once the compiling has completed. Connect the J-Link tool to the USB port of the PC, and connect the flat cable with the programming adapter. Plug the adapter into the dongle connector. Press the Debug icon, CTRL+D or click Project\Debug. The debugger starts to download the firmware to the dongle through the J-Link debugger\programmer. Press the Go button, F5 or click Debug\Go in order to execute the firmware in Debug mode. To run the dongle in Standalone mode, press the Stop Debugging icon, CTRL+SHIFT+D or click

In order to use the application project, it is necessary to:

● Include all the firmware delivered in the In-Home Display with HTTP gateway package containing the FreeRTOS core files, see Figure 13.

● Create the desired menu application functions in the file menu.c.

● Put inside “picture.c” the HEX dump of the pictures to be used with the application GUI.

● Implement a main function as described in the following section.

7.6 Example application - main.cAn example of a main application is reported below. The main function contains an example of the In-Home Display with HTTP gateway application initialization/configuration and implements the classic operations:

The initialization process is charged with preparing the basic mechanism of the system:

● Hardware peripheral configuration and initialization

● ZigBee stack initialization

● FreeRTOS task creation

● Starting system.

The clock distribution and the interrupt settings are two components which are strongly dependent on the target project. An example of clock rate may be 72 MHz as the maximum


Doc ID 022809 Rev 2 55/81

speed of the current STM32 microcontroller. It can be decreased to reduce the power consumption. The clock rate assumptions are:

● System HCLK - 72 MHz

● Low speed peripheral PCLK1 - 72 MHz

● High speed peripheral PCLK2 - 36 MHz

● Analog-to-digital converter ADCCLK - 36 MHz.

The interrupt setting situation is very similar to clock distribution. The library functions involved with interrupt managing do not take the priorities into account; they only perform very necessary and absolutely common settings to make them serviceable.

In-Home Display with HTTP gateway GUI application AN4049

8 In-Home Display with HTTP gateway GUI application

8.1 Application user interfaceAfter a board reset, if the firmware is correctly loaded into the Flash memory and the board power is correctly supplied, the main screen is displayed, as shown in Figure 16.

Figure 16. Home screen

If the network has already been set up in the past, after some seconds, when the ZigBee network initialization is complete, the home screen looks like that in Figure 17.

Figure 17. Home screen after ZigBee network initialization done

At this point, the ZigBee nodes can be switched on and joined to the ZigBee network just created. The default channel is 16, so set it on the ZigBee nodes accordingly.

AN4049 In-Home Display with HTTP gateway GUI application

Doc ID 022809 Rev 2 57/81

If “Management” is chosen, two situations are possible:

a) If no plug is connected to the smartplug coordinator, the following screen is shown:

Figure 18. No plug detected

From this screen it is possible to run the ZigBee network setup by which a new ZigBee network is formed. The screen in Figure 19 is shown:

Figure 19. Setup ZigBee network


58/81 Doc ID 022809 Rev 2

If no network already exists with the current coordinator, the screen in Figure 20 is shown:

Figure 20. Setting ZigBee network up

If a ZigBee network had already been set up, it must be reinitialized, so the screen in Figure 21 is shown:

Figure 21. Reinitializing ZigBee network


Doc ID 022809 Rev 2 59/81

b) If one or more plugs are detected the following screen is shown:

Figure 22. Plug detected

There are three main buttons: modify, control and identify. They allow the management of the smartplug device.

If “Modify” is chosen, the user can change the label of the selected plug, through the screen shown in Figure 23, choosing the new label from a list contained in a combobox.

Figure 23. Label changing

The user should scroll the list of the labels and select the “Apply” button in order to save the information and set the label also in the plug device via ZigBee protocol.


60/81 Doc ID 022809 Rev 2

When “Control” is chosen, it is possible to switch on/off the smartplug device. The following screen shows the scenario:

Figure 24. Smartplug management

When “Identify” is chosen, the system shows the network ID of the selected node, which is a 16-bit number shown in hexadecimal format. Figure 25 below shows the respective screen:

Figure 25. Identify

In the home screen, by clicking on “Statistics” it is possible to see the electrical consumption of the single smartplug device or the total consumption related to all plugs connected to the smartplug coordinator.


Doc ID 022809 Rev 2 61/81

The following screen is shown:

Figure 26. Smartplug statistics

When energy is chosen, the following screen, representing the energy consumption of the selected smartplug device, is shown:

Figure 27. Energy consumption


62/81 Doc ID 022809 Rev 2

When global energy is chosen, the following screen, representing the energy consumption of the whole smartplug network, is shown:

Figure 28. Global energy consumption

When power is chosen, the following screen, representing the power consumption of the selected smartplug device, is shown:

Figure 29. Power consumption


Doc ID 022809 Rev 2 63/81

When global power is chosen, the following screen, representing the power consumption of the whole smartplug network, is shown:

Figure 30. Global power consumption

When the refresh button is chosen, it is possible to make a refresh of the graph chart in relation to the sampled points of the power consumption.

When the home button is chosen, it returns to the home screen.

On the home screen, by clicking on “Demo Scenario” it is possible to set a configuration for the nodes in order to enable automatic timers.

Only the first two nodes can be configured for the demo scenario.

The following screen is shown:

Figure 31. Demo scenario

When the “Set Timer” button is chosen, a new screen is shown where the user can set up the parameter for the timer related to a smartplug node.


64/81 Doc ID 022809 Rev 2

Figure 32. Set timer

After setting up the parameters, the user must choose “Save Parameters” in order to apply the changes. Then, the user must choose “Back”, bringing up the previous screen so that the timer can be activated with the respective button. Before activating the timer, the user can set it for another smartplug, so that the timer scenario is activated for 2 devices (the maximum allowed for the demo).

Clicking on the “Activate” button, the following screen is shown:

Figure 33. Activate timer

In this way, the demo scenario is running and the node for which the timer is activated is switched on and off according to the timer parameters set in the previous screen. In this screen the user can visualize the current date and time, the node status (off or on) and the instant power consumption. If the timer is activated also for a second node, its status and power consumption are shown after those of the first node.

When the home button is selected, it returns to the home screen.

AN4049 Web server hosting energy consumption data

Doc ID 022809 Rev 2 65/81

9 Web server hosting energy consumption data

9.1 Features overviewEach time a smartplug node joins the network and its load type is configured through the GUI interface, it starts reporting power and energy consumption measured values.

These data are received from the coordinator board and routed via Ethernet to the web server.

The user can browse these data from another PC connecting to the web server and logging in with a username and password. Then, the user can look at the reporting table, export data to an Excel file or plot them to graphical charts.

9.2 Accessing the websiteThe following image shows the login page of the web server:

Figure 34. Login page

For example, the user can log in using “guest” as both username and password.

66/81 Doc ID 022809 Rev 2

9.3 Browsing reporting dataAfter login, the browser is redirected to the following page where the user can choose the smartplug of which they want to query the reporting data. It can be selected from a combobox containing a list of all the smartplugs that have sent reports. From this page on, the user can always return using the specific “Back” button.

Figure 35. Device selection page

After selecting the smartplug device, the following page is displayed:

Figure 36. Energy data table page

AN4049 Web server hosting energy consumption data

Doc ID 022809 Rev 2 67/81

At this point, the user can:

1. Export the table of data to an Excel file, clicking on the “Export to Excel” button. See the following image:

Figure 37. Export data page

2. Plot the data to graphical charts, where the user can select the day for which to plot the data, as shown from the following screen:

Figure 38. Plotting data page

3. Return in order to select another smartplug device using the “Back” button.
