Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to record and play audio with Mbed OS on NuMaker-IoT-M487 development board. Open Chrome browser, and enter the URL https://ide.mbed.com to use the Mbed Online Compiler. After log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS” which has a detailed description of how to add a board. Click the “New” on the left of menu bar, a “Create new program” window will be displayed. You can see that the Platform has been set to NuMaker-IoT-M487. In the Template, select the "NuMaker audio playback" for this tutorial. Then click OK. Now you can see that the sample code has loaded on the page. The sample code has three functions: 1. Record 10 seconds sound and save to Micro SD card 2. Play sounds stored in Micro SD card 3. Loopback. Record sound and play it immediately. Click main.cpp to open it. Then scroll down to line 421. You can see the functions calls here. It set to loopback only. Let’s do a little modification. Hit a key on console to start record 10 seconds then play it, and then do loopback. printf("Press a key to start recording 10 seconds..."); getchar(); demo_record(); demo_play(); demo_loopback(); Save it and click “Compile” to build the code. Compilation takes a while, please wait. After the compilation is completed, “Success” will appear in the compile output window. The browser downloads the binary firmware file directly after a successful compiling. It will be saved in a default download folder. In Chrome, you can click download file and select “Show in folder”. Please plug an earphone commonly used for mobile phone in headphone jack on NuMaker-IoT-M487 board. For demonstration, we use a headphone splitter cable to connect a microphone and a speaker. Do not put the microphone and speaker too close to avoid feedback howling. Then connect the USB port to your computer and make sure the onboard LED lights up. Back to the folder you just download the binary firmware file (NuMaker-mbed-AudioPlayback-example.NUMAKER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. Please find the virtual COM port assigned for NuMaker-IoT-M487 in Device Manager. In the demonstration, the “Nu-Link Virtual Com Port” is COMx. Then use your favorite terminal tool. Here we use Putty. Open the COMx port with 9600 baud rate. And no flow control settings. Then “Open” it. Press “Reset” on board to run the firmware again. Press a key on terminal to start record. Speak for about 10 seconds, then your voice will be played. That’s all for this tutorial. Thank you for watching. Welcome to subscribe to our channel.

Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to control the temperature and humidity sensor with Mbed OS on NuMaker-IoT-M487 development board. For this tutorial, we choose the “Thermo 6 Click” board. It is a mikroBUS board with a MAX31875 sensor. It is easy to install on NuMaker-IoT-M487 board because it has a mikroBUS connector. The part of control code refer from community, it is easy and quick to be integrated into real application. Open Chrome browser, and enter the URL https://ide.mbed.com to use the Mbed Online Compiler. After log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS” which has a detailed description of how to add a board.

Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to use 4G LTE or NB-IoT with Mbed OS on NuMaker-IoT-M487 development board. This tutorial needs a cellular expansion board to work with NuMaker-IoT-M487 development board. You can purchase the 4G LTE expansion board, RF-EC21A, on Nuvoton Direct (https://direct.nuvoton.com/communication-module/). Please install your 4G LTE SIM card in the mini SIM card slot on the back, and install the antenna at the MAIN connector on the front of the board. Although there is an NB-IoT expansion board, it requires an NB-IoT SIM card. Using LTE is more convenient. Just use your own LTE SIM card which has data plan. Then install the expansion board to the Arduino UNO connector of the NuMaker-IoT-M487 development board. Because the power consumption of the 4G LTE module is higher, it is not enough to supply power from USB only. You need to plug in the 5V/2A power supply. If you use NB-IoT module, no additional power supply is needed. We used “New” to select a template to create a new project. This time, we use the example on GitHub to create a new project. The URL of template used for this tutorial is https://github.com/OpenNuvoton/NuMaker-mbed-Cellular-example In chrome browser, enter the URL https://ide.mbed.com to use Mbed Online Compiler environment. After you log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS” which has a detailed description of how to add a board. Click the second option “Import” on the upper left. In the Import Wizard, click “Click here” On the “Source URL:”, enter the tempalte URL https://github.com/OpenNuvoton/NuMaker-mbed-Cellular-example . Then move mouse cursor to “Import Name:” and click it, the Project name will be automatically fill in. Then click “Import” button. Now you can see that the sample code has loaded. Depending on the cellular module used, the configuration may need to be modified. Click on “Readme.md” to open it. It lists configurations for supported cellular modules. Because the tutorial uses RF-EC21A expansion board which includes a Quectel EC21 LTE module, let’s check and modify the configuration in mbed_app.json file. Click the “mbed_app.json” file to open it. It is a JSON file to customize compile time configuration parameters in Mbed OS. The “*” (asterisk) in “target_overrides” session indicates all development boards are applicable. You can set in the designated board session, so the settings are only applicable to the specified board. The default mbed_app.json file in the example has configured for RF-EC21A. Such as, "target.network-default-interface-type" has set to "CELLULAR" for cellular connection. Both "lwip.ppp-enabled” and "lwip.tcp-enabled" set to true. Use generic AT3GPP driver for RF-EC21A ("GENERIC_AT3GPP.provide-default": true) And the RF-EC21A UART connects on Arduino D0/D1 ("GENERIC_AT3GPP.tx": "D1" and "GENERIC_AT3GPP.rx": "D0") When your SIM card installed in your mobile phone, you can find the APN, username and password settings in your mobile phone. Or contact your telecom operator to get this information. In the example, APN has set to “internet”, no username, and no password. (Move mouse cursor around these settings) The final setting to check is PIN code. In the example, the setting is no PIN code. If your SIM card has PIN code, for example 1234, please set it like this “\”1234\”” (Move mouse cursor around the setting) Save it then build it. It is in compiling, please wait a moment. Then you can see the last message is “Success!”. The browser will download the binary firmware file directly after a successful compiling. It will be saved in a default download folder or the folder based on your browser setting. In Chrome, you can click download file and select “Show in folder”. Then we connect the NuMaker-IoT-M487 USB port to your computer and don’t forget to plug in external 5V power supply. Please find the virtual COM port assigned for NuMaker-IoT-M487 in Device Manager. In the demonstration, the “Nu-Link Virtual Com Port” is COMx. Then use your favorite terminal tool. Here we use Putty. Open the COMx port with 115200 baud rate, 8 bits, 1 stop bit, none parity, and no flow control settings. Then “Open” it. Let’s back to the download folder where you can see the binary firmware file (NuMaker-mbed-Cellular-example.NUMAER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. You can see the connection messages printed on terminal. It shows that the board creates a TCP connection to server “echo.mbedcloudtesting.com”, send 4 bytes data and get the data back from server. That’s all for this tutorial. Thank you.
