  • 新唐 NuMaker-IIoT-NUC980 – 學習透過 GPIO 控制 LED (2)
    Watch time - 3:31
    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

  • NuMicro M2351 For Auto-Metering Infrastructure
    Watch time - 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

  • 新唐 NuMaker-IIoT-NUC980 – 如何安裝 NuMaker NUC980 IIoT開發環境 (1)
    Watch time - 4:14
    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

As you can see, the microcontroller controls the 2-inch OLED screen and GIF files can be played on it. The M480 series runs up to 192 MHz with 512 KB embedded Flash memory and 160 KB embedded SRAM. The high-performance MCU decodes GIF motion graphics smoothly. There are three major features about this reference design: First: We use the Nuvoton M480 high-performance microcontroller to control the OLED through high-speed SPI to showcase dynamic effects. Second: This solution has built-in GIF decoding and various font libraries. If there are other font requirements, you can load other fonts through the Nuvoton font conversion tool, and use the emWin Library to develop a high-quality user interface quickly. Third: It can be applied to products requiring display functions, such as e-sports motherboards, which can dynamically display temperature, the speed of the fan and the status of the hard disk. The OLED device has a 2-inch OLED screen with a resolution of 256*64. There is an SD card slot underneath, which obviously is for data storage and the storage status is shown on the OLED screen. The right side, there is a high-speed USB for PC connection as a flash drive. A headphone jack is on the left, I’m sure you all know how it works.
