Hello everyone, I am the principal engineer of Nuvoton Technology, Morgan. The development board we are using today is Nuvoton’s NuMaker-IoT-M487. It is powered by the NuMicro M487 microcontroller with Arm Cortex-M4 core, built-in RJ45 Ethernet, and Wi-Fi module allowing users to connect to clouds by wire or wirelessly. It supports several RTOS including Arm Mbed OS, Amazon FreeRTOS, and AliOS Things. Today, I will show you how to use Mbed OS on the NuMaker-IoT-M487 development board. First, open Chrome browser, enter the URL https://os.mbed.com to register an account if you don’t have one. Move the mouse cursor to the human icon in the upper right corner then click “Log in or Sign up” or click “Sign up for free” directly. Then click “Sign up” Fill in your e-mail address and relevant information, and finally click Sign up. Check your mailbox to receive the certification letter and authorize it. Then let’s log in to use the online compiler environment. Move to the human icon in the upper right corner, and then click “Log in or Sign up”. And enter your account and password. After a successful login, it will return to the first page and then click “Compiler” on the left side of the human icon. It will lead us to the online compiler web page. The following demonstration is all operated on this page Click “No device selected” in the upper right corner to add and select Nuvoton’s NuMaker-IoT-M487 development board. It opens the “Select a Platform” page. We click the button, show “Add Board” with green “+”, in the lower-left corner. Next, it shows the page, let us choose a board. Scroll down to find NuMaker-IoT-M487, and click it. It opens the NuMaker-IoT-M487 board page (https://os.mbed.com/platforms/NUMAKER-IOT-M487/). Scroll down the page to find the button “+Add to your Mbed Compiler”, and click it. Click “Compiler” on top of the page to return to the online compiler environment. If the “NuMaker-IoT-M487” small icon appears in the upper right corner, you can start to import a sample code. Otherwise, click “No device selected” again. At this time, you can see the NuMaker-IoT-M487 icon already in the “Select a Platform” dialog box, click the icon to select it and then click “Select Platform” in the upper right corner. It returns to the online compiler page, and the “NuMaker-IoT-M487” icon shows in the top right corner. You can now start to import a sample code. First, click “New” on the top left side, a small “Create new program” dialog box appears. The “Platform” selects “NuMaker-IoT-M487” automatically. In the “Template” field, please select “mbed OS Blinky HelloWorld” example code, click OK. You can see the sample project has been loaded on the page, click “main.cpp” to show the source code. Let’s add a printf() function to print out a string in the main program. Check if statements are correct, save it, and click “Compile” to build code. Now it’s compiling, let’s wait for a moment. And you can see a lot of messages at the bottom of the page. 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 any folder based on your browser setting. In Chrome, you can click download file and select “Show in folder”. Then we need to connect the NuMaker-IoT-M487 USB port to your computer and make sure the onboard LED lights up. Let’s head back to the download folder where you can see the binary firmware file (mbed-os-example-blinky.NUMAKER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. After the copy is completed, the firmware starts to execute. One LED on board starts blinking. To see the printout message, go on the following steps. 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 terminal tool of choice. Here we use Putty. Open the COMx port with 9600 baud rate, 8 bits, 1 stop bit, none parity, and no flow control settings. You can see “Hello World!” printed in the terminal. That’s all for this tutorial. Thank you for watching.

以新唐 NuMaker NUC980 IIoT 為平台，使用 Linux 進行開發，學習開發各式功能，觀看本片，您將學會如何控制 GPIO 使 LED 閃爍。 哈囉大家好，我是新唐工程師 Kevin，今天為大家介紹如何在 NuMaker NUC980 IIoT 板子上透過 GPIO 讓 LED 燈閃爍。 NuMaker NUC980 IIoT 板子的 Power-on Setting上方有 3 個 LED 燈，分別由不同的 GPIO 控制。最左邊，編號 LED03 的 LED 燈是由 GPIO B8 這根 pin 控制。今天示範如何用程式控制 GPIO B8 讓 LED 燈閃爍。 這是 LED 燈閃爍的程式，在看程式之前，我先為各位說明，在 Linux kernel 中，每一根 GPIO pin 都有編號。每一個 GPIO Group 占用 32個編號，編號為 0 到 31，分配給 GPIO Port A 這個 group，編號 32 到 63 分配給 GPIO Port B，以此類推。 LED03 這個 LED 燈是由 GPIO B8 這根 pin 控制，GPIO B8 在 Linux 中的編號是 40。 回到程式中，我們看到這個程式是透過 system function 執行系統命令，透過 Linux kernel 的 sysfs 控制 GPIO。 第 23 行 system("echo40 /sys/class/gpio/export"); 是將 GPIO B8 設定成可以用sysfs 控制。 第 24 行 system("echo out /sys/class/gpio/gpio40/direction"); 是將 GPIO B8 設定為 output。 接下來在 while loop 中，透過 system("echo 1/sys/class/gpio/gpio40/value"); 讓 GPIO B8 輸出 high；再透過 system("echo 0 /sys/class/gpio/gpio40/value"); 讓 GPIO B8 輸出 low，中間延遲 1 秒鐘，就可以做到 LED 燈閃爍的功能。 這個程式，main.c，儲存後，進行 compile 輸入 arm-linux-gcc main.c -o gpio_toggle (輸入 ls) 產生一個執行檔 gpio_toggle 將 gpio_toggle 拷貝到 root file system 目錄中， (輸入 sudo cp gpio_toggle ../rootfs) 然後重新 compile Linux Kernel 透過 NuWriter 將 Linux kernel 下載到NuMaker NUC980 IIoT 板子上執行 Linux Kernel 開機完成後，輸入 ./gpio_toggle，執行閃爍 LED 的程式。 此時可以看到 NuMaker NUC980 IIoT 板子上的 LED 正在閃爍。 - 更多產品資訊，請至新唐科技網站 https://bit.ly/3hVdcmC 購買管道：https://direct.nuvoton.com/tw/numaker-nuc980-iiot 聯絡我們： SalesSupport@nuvoton.com

Secure Smart Metering Communication Reference Design Hi everybody, today we are going to introduce a reference design of Smart-Metering communication card based on NuMicro M2351 Series microcontroller. You can find useful security features based on the Arm Cortex-M23 CPU core with Nuvoton’s in-house technology integration. The auto-metering is an infrastructure for automatic, remotely, wire or wireless meter data reading. It’s highly possible to be intervened if there is no security mechanism. That is a very typical IoT security issue in the IoT era. In many countries, there are a lot of Auto-Metering Infrastructure (AMI) projects being undertaken by main electricity power companies worldwide. Most projects start from upgrading the communication modem cards as the first step rather than retiring the meters. The modem card can play as a gateway to monitor the incorrect device operation and data transmission security. Issues of modem card security are covering: First, a limited performance due to crypto computation efficiency Second, speed limitation due to interface choice The third, cost burden due to extra hardware modules for different communication protocols Nuvoton’s reference design of Secure Smart Meter Communication is an end-to-end security solution for AMI. With the collaboration with SPI-Korea, the solution incorporates a lot of advantages such as TrustZone security for firmware, a range of interfaces for device communication, secure over-the-air firmware update, and remote management. With the complete hardware specification of M2351, a security software company, SPI-Korea, can easily implement their secure AMI solution for modem card which connects meters and cloud servers. M2351 also contributes the crypto acceleration during the cryptographic computing in order to save CPU time for different communication protocol modules by its powerful hardware functionalities during message transmission outside of a microcontroller unit. SPI-Korea has developed a range of Armv8-M TrustZone based technologies. Her expertise covers Boot Manager, Key Manager, and Device Manager, which is very useful for microcontroller security and certainly shows the stability of a microcontroller device. Also, they are certified by Korea Electricity Company. We hope this successful experience can be further adopted in other areas worldwide because it’s a secure, accurate and environmentally safe solution for AMI. This slide is a picture for SPI-Korea AMI modem card design. NuMicro Family microcontrollers can be utilized for designs of auto-metering infrastructure devices. We start from AMI modem card and we are confident to support meters of any next-generation of AMI. We now integrate M23-based microcontroller with M4-based or Arm9-based microcontroller as a proposal for next-generation modem card of Korea AMI and we hope to provide high-performing cost-effective solution for all AMI devices in the future. - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC contact us: SalesSupport@nuvoton.com
