  • NuMaker-IoT-M487 (8) Use SD Card on Mbed OS
    培訓  工具  學習  影片長度 - 3:55
    Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to use SD card 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 SD-File-System with SD mode" for this tutorial. Then click OK. Now you can see that the sample code has loaded on the page. LittleFS uses less memory, supports power failure protection. However, LittleFS is different from the FAT file system, so after uses littleFS, the SD card will be formatted as LittleFS. The sample code uses FAT file system as default. Just click “Compiler” to build the example. It is in compiling, please wait a moment. After the compilation is complete, “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 or the folder based on your browser setting. In Chrome, you can click download file and select “Show in folder”. Please insert a micro SD card into the card slot on the back of NuMaker-IoT-M487 board, then connect the USB to your computer and make sure the onboard LED lights up. Let’s back to the folder you just download the binary firmware file (NuMaker-mbed-SD-FileSystem-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 115200 baud rate And no flow control settings. Then “Open” it. Press “Reset” on board to run the firmware again. You can see the messages on terminal while accessing SD card. That’s all for this tutorial. Thank you for watching. Welcome to subscribe to our channel.

  • 新唐 NuMaker-IoT-M263A 使用 Mbed OS – 使用 SD 卡 ( 6 )
    前瞻應用  學習  影片長度 - 3:42
    以新唐 NuMaker-IoT-M263A 為平台，使用 Mbed OS 進行開發，學習各種功能。觀看本片，您將學會使用 NuMaker-IoT-M263A 開發板配合 Mbed OS 範例程式存取 SD 記憶卡。 哈囉大家好，我是新唐工程師 Miya，今天為大家介紹如何使用新唐 NuMaker IoT-M263A 在 MbedOS 使用 SD Card。 首先打開 Chrome 瀏覽器，輸入網址 "https://ide.mbed.com/"，登入後先確認右上方板子已經有帶出 “NuMaker-IoT-M263A 及板子小圖示” 了，如果沒有可參考教學影片 “step by step 讓你了解如何運行 Mbed OS”，裡面有詳細的示範怎麼新增板子的方法。首先點選左上方的 “New”，會載入一個 Create new program 的小視窗，可以看到 Platform已經帶出 NuMaker-IoT-M263A，在 “Template” 這欄選取 sample code，使用 NuMaker SD-File-System with SD mode 這個 sample，點一下 OK。 現在可以看到 sample code 已經載入頁面，這個範例預設採用 FAT file system，LittleFS 佔用比較少的記憶體，支援斷電保護，但 LittleFS 與 FAT file system 不同，若允許格式化 SD 卡及變更原本 SD 卡的 FAT file system 為 LittleFS，可執行修改 main.cpp 的動作。在這版本的第 34 到 40 行的地方，可以看到說明這個 example code內定是用 FAT file system，若要改成使用 LittleFS，就可先將預設的 FAT file system 設定在第 35 及第 36 行改為註記，接著將第 39 及 40 行的註記符號刪除。教學影片示範編譯的檔案是使用 FAT file system，程式碼不需更動，所以這邊將剛才的示範改回。確認程式碼中設定的檔案格式後存檔，按 Compile 編譯程式，編譯中需要等待一下，編譯完成後下方會出現 “success!”。 系統會把編譯完成的 bin 檔放在 download 資料夾，直接從下方進入，上拉後點一下 “Show in folder”，到預設的 download 夾。先確認已將 micro SD Card 插在板子後，再將 NuMaker-IoT-M263A 板子跟 PC 接上 USB，確認板子有亮燈就是通電了。回到 download 資料夾，可以看到多了一個剛才 compile 完成的 bin 檔，按右鍵傳送到 NuMicro MCU(E:)，這邊分配到哪一槽要看各位的電腦決定，有成功點選到的話會出現傳送過去的畫面。 到電腦的裝置管理員查看分配到的 port 編號，在本機按右鍵，點裝置管理員，找到連接埠 (COM 和 LPT)，找到 USB 序列裝置，就可以知道像這部 PC 分配給它的是 COM12。接下來使用終端機模擬軟體，各位可以用自己熟悉的軟體操作即可，設定 Serial line 為 COM12，Speed 為 115200，到 Serial 將 Flow control 改為 None，接著 OPEN。設定好之後在板子上按一次 reset，接著在終端機摸擬軟體就可以看到系統回傳測試 SD Card 的資料。 以上是這次的教學影片，感謝您的收看，如果您想知道更多資訊歡迎聯絡我們。 - 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-iot-m263a 聯絡我們： SalesSupport@nuvoton.com #application #learning #intermediate #zh-Hant

  • NuMicro M2351 For Auto-Metering Infrastructure
    影片長度 - 4:59
    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
