以新唐 NuMaker-IoT-M487 為平台，使用 Mbed OS 進行開發，學習開發各式功能。觀看本片，您將學會如何以 Mbed OS 範例程式透過 NB-IoT 或 LTE 連接到伺服器並讀取回傳資料。 哈囉大家好，我是新唐工程師 Miya，今天為大家介紹如何讓新唐 NuMaker IoT-M487開發板在 MbedOS 上使用 NB-IoT 以及 4G 模組。 以下錄影板子教學子板接母板教學 現在需要先進行組裝在新唐商店購買收到的 RF-EC21A-EC21 LTE 模組與子板，先翻至背面，插入 4G SIM Card，再翻至正面，將天線插在 ”MAIN” 孔。再將子板與母板上的字母朝同一方向對齊組裝。 因為 4G 模組較秏電，所以在使用 4G 模組時，單用 USB 供電是不夠的，需要將 5V / 2A 之電源插上；若使用 NB-IoT 模組則不需再額外插上電源。 組裝好 4G 子板後，到搜尋引擎搜尋 opennuvoton，找到並進入 nuvoton GitHub 進入新唐的線上 GitHub 頁面，搜尋這次所使用的檔案 NuMaker-mbed-Cellular-example 點進去後，複製網址，接下來到網址 https://ide.mbed.com/ 登入後先確認右上方板子已經有帶出 ”NuMaker-IoT-M487 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喔！ 選取左上方第二個 ”Import” 選項在 Import Wizard 中，點 Click here， 將剛才在 nuvoton Git-Hub 中複製的網址貼到 Source URL: 中，將滑鼠在 Import Name: 中點一下讓 Project name 可以自動填入，完成後按 Import。可以看到系統已將 sample 載到頁面裡了，先到 README.md 中閱讀裡面的說明，前 2 個是 NB-IoT模組，後面的 QUECTEL EC2x 是 4G模組。這次的示範是使用 QUECTEL EC2x 子板，先找到在這版本的程式中是從第 36行開始為 QUECTEL EC2x，在第 39 行 ~ 第 41 行的地方複製這三行的定義。 再到 mbde_app.json，把剛才複製的三行定義貼到 target_overrides 也就是第20 行開始的地方。 貼好之後，把 ppp-enable 與 tcp-enable 也就是第 27 跟第 28 行改成 true。改好之後存檔，編譯。 現在 Compile 中，需要等待一下，完成後最下面會秀出 Success！ 系統會把我們 compile 完成的 bin 檔放在 download 資料夾，我們可以直接從下方進入，上拉後，點一下在資料夾中顯示 接著我們需要把 NuMaker-IoT-M487 板子跟 PC 接上 USB，記得使用 4G 模組要外接電源。 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 COM3。接下來使用終端機模摸擬軟體，各位可以用自己熟悉的軟體操作即可，設定Serial line 為 COM3，Speed為115200，到 Serial 也確認一下 baud: 115200，接著OPEN。再回到剛才的資料夾，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喔！ 點選成功，會出現傳送資料畫面。 接著回到終端機摸擬軟體，可以看到板子已經成功連到echo.mbedcloudtesting.com server ，傳送 4 Bytes資料後接收 4Bytes 資料，比對正確，連線測試成功。 - 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-m487 聯絡我們： SalesSupport@nuvoton.com #Tool #Training #Learning #Intermediate #zh-Hant

以新唐 NuMaker NUC980 IIoT 為平台，使用 Linux 進行開發，學習開發各式功能。本片示範如何啟用乙太網路連接網際網路。 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 Ethernet 連網。 NuMaker NUC980 IIoT 板子上的 Ethernet port 位於右上角，請記得接上網路線才能連網。 在安裝 NUC980開發環境 Buildroot 的過程中，我們下 “make nuvoton_nuc980_iot_defconfig” 產生 NUC980 IoT default configuration，當中 Ethernet 相關的設定已經打開。今天我們要使用一個網路應用程式，curl，在 NUC980 IoT default configuration 中，這個選項是關起來的，所以要透過 “make menuconfig” 打開。 進入選單後，選擇 “Target packages ”，”Libraries ”，” Networking ”，把 “libcurl”和 “curl binary” 這兩個選項打開。儲存設定後離開 menuconfig。 然後再下 make 重新 compile Buildroot。 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 “udhcpc –i eth0” 向 DHCP server 要一個 IP address。 先測試網路的狀況，輸入 “ping google.com”，可以看到網路是通的。 接下來我們要透過剛才安裝的 curl 來下載檔案，我們輸入 “curl http://os.mbed.com”，就可以下載 mbed 首頁的 html。 - 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
