Brief Function Introduction on Boards 1.1
1.1.1 NuMaker-emWin-M487D Board
The NuMaker-emWin-M487D board shown in the Figure 1-5 below provides user the Human-Machine Interface (HMI) function. Users can control the power switches to turn on or turn off the power on these AC sockets and USB sockets on M487 Smart Power board by touch finger input on TFT LCD screen. On the other hand, the real-time current and power consumption of each be turned-on socket are displayed on the TFT LCD screen and the On/Off status also shown on LED.
In this M487 Intelligent Power Station application and for the destination to fit all hardware boards into the case, users can find some components of NuMaker-emWin-M487D board are be removed and be replaced with LEDs. Figure 1-6 shows the reworked NuMaker-emWin-M487D board.
This NuMaker-emWin-M487D board is a master role in this M487 Intelligent Power Station application. It arbitrates the speech recognition command passed from NuMaker-IoT-M487 board through the Wi-Fi module (UART interface) of M487 Smart Power board with the HMI input and then sends the last command by UART to control the power switches to turn on or turn off the power on these AC and USB sockets.

1.1.2 M487 Smart Power Board
The M487 Smart Power board is based on M487JIDAE MCU chip to implement the real power switch controlling and measure the current and power consumption on each AC and USB socket if it is turned-on by the NuMaker-emWin-M487D board. It sends back the real-time current and power consumption to NuMaker-emWin-M487D board to display on the LCD module through the UART interface.
This board also plays the role of UART bridges. It passes the command from NuMaker-emWin-M487D board to the DALI master board through the UART interface with the transceiver. On the other hand, it also passes the speech recognition command through the Wi-Fi module (UART interface) from NuMaker-IoT-M487 board to NuMaker-emWin-M487D board to arbitrate the command with HMI input.
Figure 1-7 shows the M487 Smart Power (V1.1) board.

1.1.3 DALI Master and Slave Boards
The DALI combination board that consists of a DALI master board and a DALI slave board is a slave device in M487 Intelligent Power Station system. It always receives the command passing through the UART interface of M487 Smart Power board from the HMI input of the NuMaker-emWin-M487D board to control the lux and fade-out time of light on the DALI slave board.
Figure 1-8 shows the combination board that combines a DALI master board with a DALI slave board and these two boards meet the DALI 2.0 specification.

1.1.4 NuMaker-IoT-M487 Board and NuTFT-SPI_320x240 Daughter Board
The NuMaker-IoT-M487 board is also based on M487JIDAE MCU chip to implement the rich Internet-of-Thing (IoT) applications. In this M487 Intelligent Power Station application, the firmware on the embedded flash of M487 chip has been implemented a speech recognition algorithm with machine learning. The firmware transfers the speech command based on some fixed key words to the NuMaker-emWin-M487D board thru the Wi-Fi module (UART interface) and UART interface of M487 Smart Power board. After speech recognition completed, the TFT LCD of the NuTFT-SPI_320x240 daughter board shows the digit number the result of speech recognition from M487 MCU through the SPI interface.
Figure 1-9 shows the combined picture of NuMaker-IoT-M487 V1.2 board and the NuTFT-SPI_320x240 V1.3 daughter board.

Human-Machine Interface (HMI) 2.2
In this M487 Intelligent Power Station application, the firmware had been implemented with Human-Machine Interface (HMI) function based on the emWin engine and the binary code also had been programmed into the embedded flash of M487 chip on the NuMaker-emWin-M487D board.
Through this HMI interface, users can control the power switches to turn on or turn off the power on these AC sockets and USB/DC sockets on M487 Smart Power board by touch finger input on TFT LCD screen. On the other hand, the real-time current and power consumption of each be turned-on socket are displayed on the TFT LCD screen and the On/Off status also shown on LED.
2.2.1 Boot Animation
For each time, user plugs the AC plug into the AC power socket on the wall to power-on the M487 Power Station case and user will see a boot animation displayed on the TFT LCD screen about three seconds. Figure 2-2 shows the boot animation displayed from some nuvonTon GIF files.

Speech Recognition 3.2
The speech recognition is based on machine learning. A complete deep learning speech recognition system requires two platforms. As Figure 3-3 shows, one is PC platform. We program the deep learning code and train the model by Tensorflow and Python. Due to the supervised learning for the training mode, it is necessary to give the system a large amount of training data and labels. Then extract the features of speech data and train the model by deep neural networks (DNN). Until the system reaches the optimization, we evaluate the accuracy by modifying the training model repeatedly. The other platform is NuMaker-IoT-M487. The speech recognition system can be implemented based on the training parameters from PC platform.
Figure 3-3 The Flow of Speech Recognition
There are ten English digits used for this recognition scheme: One, Two, Three, Four, Five, Six, Seven, Eight, Nine and Zero. The NuMaker-IoT-M487 and the Nu TFT LCD GUI development platforms are utilized in the speech recognition system. When the user says “One” to the microphone, the number “1” will be shown on the LCD panel by identifying the keyword correctly. And the number command will be transferred to the M487 Intelligent Power Station via Wi-Fi to toggle the power switches of the AC sockets (number 1~3) or DC/USB sockets (number 4~6).

This M487 Smart Power (V1.1) board consists of a main board and a daughter board.
The main board controls and supplies the AC power for the AC power sockets and supplies a stable DC 5V power thru an AC-DC5V adaptor for the system. This board also uses a M487JIDAE chip as microcontroller to control the whole operations on this system. The M487 MCU controls the relay switches for the AC power sockets and measures the currents from the current sensors that monitoring on these AC power sockets by 3-channel ADC inputs of MCU.
The daughter board consists of three sets of MOSFET devices and three USB type-A sockets. The M487 MCU also controls the USB switch devices to supply the DC 5V for these USB type-A sockets and switches the MOSFET devices to measure the currents that passing through these sockets by 9-channel ADC inputs of MCU. These control signals and ADC channels come are connected with the main board thru three connectors.

The Pin Function of M487 Chip on M487 Smart Power Board 4.7
The M487JIDAE chip provides many GPIO pins in LQFP144 package. Each pin has multi-functions that can be configured by user in the firmware. On this M487 Smart Power board, we used and defined a lot of pins that each used pin has a dedicated function for this system application.
The Table 4-1 to Table 4-4 shows the dedicated function tables on each used pin of M487 chip on this M487 Smart Power board.

4.9.3 AC Power
Figure 4-10 shows the AC power, relays and current sensor devices circuit. In this circuit, the bridge rectifier DF1510 (U5) and phototransistor coupler 4N25 (U4) can be used to detect the zero-cross of AC input power. The relay (LS1, LS2 or LS3) is a switch device that controlled by a GPIO pin of M487 MCU to enable or disable AC power supplying to the external AC socket. The current passing through the AC socket will be transformed by the current sensor (U2, U3 or U6) and its output can be monitored by the ADC channel of M487 MCU.

4.9.11 USB Daughter Board
Figure 4-20 shows the USB daughter board circuit. The Power-distribution Switch (U8, U9 or U10) is a switch device that controlled by a GPIO pin of M487 MCU to enable or disable DC 5V power supplying to the USB socket. This switch device will generate a LOW output on its #OC pin to indicate MCU to disable the 5V output when it detects an over current on the 5V output power. For each USB socket, the circuit utilizes three MOSFET devices (Q4/Q5/Q6, Q7/Q8/Q9 or Q10/Q11/Q12) that can be switched to three different resistor paths by three GPIO pins of MCU. The current passing through the USB socket will be measured by the one of three ADC channels of M487 MCU.
