Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to use Wi-Fi with Mbed OS on NuMaker-IoT-M487 development board. First, open Chrome browser, enter the URL https://ide.mbed.com Please make sure that NuMaker-IoT-M487 board already selected in the upper right corner after you log in. 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 upper left, a “Create new program” window will be displayed. You can see that the Platform has been set to NuMaker-IoT-M487. In the Template field, select the "NuMaker WiFi TCP Example" for this tutorial. Then click OK. Now you can see that the sample code has loaded on the page. Click on “mbed_app.json” to open it. In order to use Wi-Fi, you have to configure SSID and password to match your Wi-Fi access point setting. In the mbed_app.json file, the default Wi-Fi security set to WPA and WPA2 in “nsapi.default-wifi-security” field. Please modify the field “nsapi.default-wifi-ssid” to your Wi-Fi SSID Then modify “nsapi.default-wifi-password” to your Wi-Fi password. Click on “Compile” to build it. It is in compiling, please wait a moment. Then you can see the last message is “Success!” at the bottom of this page. 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 make sure the onboard LED lights up. Let’s back to the download folder where you can see the binary firmware file (NuMaker-mbed-wifi-tcp.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 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. Press Reset button on board to run again. You can see the connection messages printed on terminal. It shows the board’s IP address obtained from the Wi-Fi access point, sends a TCP/HTTP connection to server, and the result of return. That’s all for this tutorial. Thank you for watching.

The ML51 is a Flash embedded 1T 8051-based microcontroller. The instruction set of the ML51 is fully compatible with the standard 80C51 with performance enhanced and low power consumption. The ML51 runs up to 24 MHz at a wide voltage range from 1.8V to 5.5V, and contains up to 64/32/16/8 Kbytes Flash called APROM for programming code. The ML51 Flash supports In-Application-Programming (IAP) function, which enables on-chip firmware updates. The ML51 includes an additional configurable up to 4/3/2/1 Kbytes Flash area called LDROM, in which the Boot Code normally resides for carrying out the In-System-Programming (ISP). - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC buy now: https://direct.nuvoton.com/tw/ml51-series/ contact us: SalesSupport@nuvoton.com #Product #Learning #Basic #en 0:00 簡介 0:20 Agenda 0:45 NuMicro Product Portfolio 1:28 2019 Brand New MCU Platform 2:06 ML51/ML54/ML56 Series Portfolio 3:29 ML51 Series Low 4:50 NuMicro Naming Rule 6:06 NuMicro® ML51 Features 8:19 4 Different Power Modes 10:44 Low Power Mode Features • Wake up resource: WKT, ACMP, GPIO 12:37 Low Power VS Battery Life 13:28 ADC 15:00 Comparison of 8-bit Products Feature 17:13 Fire Fighting System 21:30 Battery Management System (BMS) 22:30 Gaming Phone 23:36 Development Board 24:13 Development Environment

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,您將學會在 NuMaker NUC980 IIoT 上使用 LTE 與 NB-IoT 連線。 哈囉大家好,我是新唐工程師阿群,今天為大家介紹如何在 NuMaker NUC980 IIoT 板子上如何使用 LTE 模組與 NB-IoT 模組。 首先我們先說明 LTE 模組的部分 NuMaker NUC980 IIoT 板子上的 USB port 位於右上角,請接上 LTE 模組才能上網。 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 LTE 和 NB-IoT 模組相關的設定已經打開。 make 編譯 compile Buildroot 編譯完成後,透過 NuWriter 將 Linux kernel 下載到NuMaker NUC980 IIoT 板子上執行。Linux Kernel 開機完成後,設定 LTE 網路,輸入 “quectel-CM &”,下載檔案,輸入指令 ” wget -c http://http.speed.hinet.net/test_010m.zip ”, 可以看見檔案正在下載。 接下來我們說 NB-IoT 的部分,NuMaker NUC980 IIoT 板子上的 USB port 位於右上角,請接上 NB-IoT 模組才能上網。 需要拿到廠商附的軟體 linux-ppp-scriptsV1.2,根據linux-ppp-scripts裡面的文件說明將相關文件拷貝到 root file system 目錄中。 => unzip linux-ppp-scripts_V1.2.zip => cp linux-ppp-scriptsV1.2/linux-ppp-scriptes/* rootfs/etc/ppp/peers/ = > vim rootfs/etc/ppp/peers/quectel-chat-connect 修改 quectel-chat-connect 裡面 APN,此 APN 參數需要根據電信業者所提供第12行修改 APN 為“internet.iot” = > vim rootfs/etc/ppp/peers/quectel-ppp 修改 quectel-ppp 裡面的帳號密碼,帳號密碼需要根據電信業者所提供 第 6 行修改 user 和 password 為空白,然後重新 compile Linux Kernel。 編譯完成後,透過 NuWriter 將 Linux kernel 下載到 NuMaker NUC980 IIoT 板子上執行。 Linux Kernel 開機完成後, 設定 NB-IOT 網路 =>“pppd call quectel-ppp &” 設定 DNS =>“ echo "nameserver 8.8.8.8" > /etc/resolv.conf ” 下載檔案 =>”wget -c http://http.speed.hinet.net/test_010m.zip ” , 可以看見檔案正在下載。 以上是這次的 LTE 與 NB-IoT 使用教學影片。 - 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

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

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,您將學會安裝 NuMaker NUC980 IIoT 的開發環境。 哈囉大家好,我是新唐工程師 Kevin,今天為大家介紹如何安裝新唐 NuMaker NUC980 IIOT 開發環境,NuMaker NUC980 IIOT是以基於Linux 系統的Buildroot做為開發環境。 在安裝 Buildroot 之前,請先瀏覽這個網頁 https://buildroot.org/downloads/manual/manual.html#requirement ,這個頁面提到 Buildroot是基於 Linux 系統;安裝 Buildroot 需要一些 package,如果缺少package 或者版本太舊的話,安裝過程會出現錯誤。所以請先確認您的 Linux 系統是否有這些 package,以及 package版本是否太舊,然後再進行安裝。 接下來在 Linux Terminal 輸入 git clone https://github.com/OpenNuvoton/NUC970_Buildroot 就可以下載 NUC980開發環境 - Buildroot。 下載完成後,產生一個新的目錄 NUC970_Buildroot,目錄名稱叫做 NUC970_Buildroot ,新唐的 NUC980 和 NUC970 系列產品共用 Buildroot,目錄名稱則以NUC970 開頭。 透過 cd NUC970_Buildroot,切換到 NUC970_Buildroot 目錄中,準備進行Compile Buildroot。 Compile分為三個步驟: (1) 輸入 make nuvoton_nuc980_iot_defconfig,產生一個預設的 configuration file。預設的 configuration 會連網安裝 U-Boot、Linux Kernel、root file system、toolchain …… 等常用的工具。 (2) 如果想要修改預設的 configuration,請輸入 make menuconfig,進入視窗選單來增加或刪減選項,修改完成後離開視窗前,請記得選擇視窗下方的 “(Save)”,儲存修改後的 configuration,然後再選擇視窗下方的 “(Exit)”,離開視窗。 (3) 回到 Linux Terminal後,輸入 make,開始進行Compile。 Compile的時間大約 1 個小時左右,如果電腦速度比較慢,就需要更久的時間。Compile成功後,NUC980 BSP 就會出現在NUC970_Buildroot目錄下面的 output 這個子目錄。 - 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
