以新唐 NuMaker-IoT-M487 為平台，您將學會如何使用 Mbed OS 範例程式，並練習如何秀出Hello World！ 哈囉大家好，我是新唐工程師Miya，新唐的NuMaker-IoT-M487 開發板，以基於Arm Cortex-M4為核心的 NuMicro M487 微控制器為主控，內建 RJ45 乙太網路與 Wi-Fi 模組，讓使用者可以有線或無線的方式連接雲端，可連接Arm Mbed，阿里雲與Amazon的FreeRTOS。 今天為大家介紹如何在我們新唐的NuMaker- IoT-M487上使用Mbed OS。 首先打開Chrome瀏覽器，輸入網址https://os.mbed.com/，註冊帳號。 點選右上角的人頭畫面，選Sign up/Log in，點選Sign up，填入相關資料 接著去信箱收認證件，回覆認證就完成註冊囉！ 接著我們登入使用，點選右上角的人頭，選Sign up/Log in，點選Log in，輸入帳號密碼。 再來點選人頭旁邊黃色底黑字的Compiler，網頁會自動幫我們導到線上開發平台頁面。 接下來的示範都是在這個頁面上操作，點選右上角的No device selected，我們先新增新唐的NuMaker IoT-M487開發板。 系統會幫我們打開Select a Platform頁面，我們點選左下角的按鈕，顯示綠色”+” Add Board，接下來會自動開啟這個頁面，讓我們選擇板子。 往下一點點找到我們的NuMaker- IoT-M487並點選，點選後會自動開啟NuMaker-IoT-M487的頁面(https://os.mbed.com/platforms/NUMAKER-IOT-M487/)將頁面接著往下拉，右邊會有藍底白字的橢圓形按鈕，顯示” +Add your Mbed Compiler”，點選它。 我們按一下上方compiler，回到線上開發平台頁面，若右上角有出現 “NuMaker-IoT-M487及板子小圖示”，就可以開始進行Sample code下載 若沒出現就再點一次 “No device selected”，這邊用另一個頁面示範，這時會跳出板子小頁面，右下方就出現了我們剛才選的NuMaker-IoT-M487板子畫面，請點它一下，在這頁面中按右上角的 “Select Platform”，我們跳回原本的頁面。 現在可以看到sample code已經load在頁面，點一下main.cpp，我們要示範印出Hello World。所以在主程式裡我們加一行指令：printf(“Hello World!\r\n”);確認一下有沒有寫錯，存檔，按一下Compile。 現在Compile中，我們等待一下。 之後可以看到頁面下方出現了很多描述，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 “Show in folder”接著我們需要先把NuMaker-IoT-M487板子跟PC接上USB，確認板子有亮燈就是通電了。 我們回到剛才的資料夾，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！ 有成功點選到的話會出現傳送過去的畫面，接著我們要到電腦的裝置管理員查看分配到的port編號，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，我們就可以知道像這部PC分配給它的是COM3。 接下來使用終端機摸擬軟體，各位可以用自己熟悉的軟體操作即可，設定Serial line為COM3, Speed為9600，到SSH也確認一下 baud:9600, Data bits: 8, Stop bits: 1, Parity: None, Flow control: XON/XOFF，接著OPEN，就可以看到剛才編輯的Hello World！印出來了。 - 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

NUC980 Series Microprocessor is a solution designed for industrial control and industrial IoT applications, such as gateway, serial server, remote control unit, plug and play data collector and IoT development platforms. NUC980 series embedded with an ARM9 core supports Linux, FreeRTOS and Non-OS Board Supporting Package. By using MCP technology, NUC980 series supports up to 128 MB DRAM. Not only can NUC980 simplify your hardware design, but help your product time to market. A less-layered PCB and a reduced PCB size can lower the BOM cost. NUC980 supports 2 High Speed and 6 Full Speed USB Host controllers that can be used for a replaceable module due to the plug and play feature of USB interface. Other interfaces include 10 UART, 4 I2C, 3 SPI, 4 CAN BUS, and 2 Camera sensor interface. Designers can use these interfaces to collect or convert the data needed. NUC980 features AES, RSA, SHA and ECC hardware crypto accelerator for CPU offloading. This crypto engine can be applied at data transfer, identification, and key exchange.Nuvoton also provides IoT protocols like HTTP, HTTPS, MQTT, CoAP, openSSL to help customers accomplish a security IoT platform easily. Nuvoton NUC980 adopts MCP technology supporting up to 128 MB DRAM. Developers can design a secure IoT product fast and convenient with the help of the hardware crypto engine. Next, I will introduce related development platforms. NuMaker NUC980 Serial Server Board is suitable for applications like serial server or serial to Ethernet gateways.
