IntroductionThis application note describes the demonstration firmware running on the STM3210C-EVAL for the STM32F107VC to manage a smartplug network system.

An embedded graphical user interface (GUI) based on the “multi-input embedded GUI library 2.0 for STM32F10xxx” described in the AN3128 application note, and working on an LCD TFT 320 x 240 display and 5-position joystick, allows the user to interact with the smartplug system made up of one coordinator and two smartplugs connected.

Section 1 describes the document and library rules.

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

Section 3 describes briefly the “multi-input embedded GUI library”.

Section 4 describes the relevant blocks of the STM3210C-EVAL demonstration board.

Section 5 shows the demonstration firmware/board system setup.

Section 6 describes, in detail, how the “in-home display” firmware is structured, its architecture and its exported APIs.

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

Section 8 illustrates how the “in-home display” GUI application works.

Section 9 illustrates the hardware schematics.

2 ZigBee smartplug

2.1 Smartplug descriptionThe 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 moduleZigBee 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

Doc ID 18209 Rev 1 9/58

3 Multi-input embedded GUI library

3.1 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.

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.

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.


Doc ID 18209 Rev 1 37/58

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

If the ZigBee dongle is not connected or the resistors R79, R84, and R169 have not been removed from the STM3210C-EVAL, the following screen is shown:

Figure 13. ZigBee dongle connection problem

After 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 14.

If Search Plugs is selected, the coordinator scans for smartplug devices for a certain length of time and the display shows the following screens in loop:

Figure 15. Searching plugs

After that, if some plugs are connected, it adds them to the smartplug list and then shows the home screen.


40/58 Doc ID 18209 Rev 1

If you click on Management two situations are possible:

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

Figure 16. No plug detected

● Once more plugs are detected, the following screen is shown:

Figure 17. Plugs detected

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

The Identify button is useful to activate the LED flashing on the relative plug, so this way the user can easily identify which plug they are going to manage through the GUI.

If Modify is clicked, the user can change the label of the selected plug, through the screen shown in Figure 18, choosing the new label from a list contained in a combobox.


Doc ID 18209 Rev 1 41/58

Figure 18. Label changing

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

When Control is clicked, it is possible to switch ON/OFF the smartplug, in case of relay type, or regulate the output power, in case of TRIAC type. The following screens show both possibilities:

Figure 19. TRIAC smartplug management


42/58 Doc ID 18209 Rev 1

Figure 20. Relay smartplug management

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. The following screen is shown:

Figure 21. Smartplug statistics


Doc ID 18209 Rev 1 43/58

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

Figure 22. Energy consumption

When Global Energy is clicked, the following screen, representing the energy consumption of the whole smartplug network, is shown:

Figure 23. Global energy consumption


44/58 Doc ID 18209 Rev 1

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

Figure 24. Power consumption

When Global Power is clicked, the following screen, representing the power consumption of the whole smartplug network, is shown:

Figure 25. Global power consumption

When the Refresh button is clicked, 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 clicked, it returns to the home screen.
