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

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

Voice controlled electronic devices have become a popular trend. The advantage is that electronic devices can be controlled without hands. For this scheme, we use Google TensorFlow as the algorithm development environment of speech recognition for deep learning. Then we implement speech recognition on NuMaker-PFM-M487 platform, and realize an offline and instant speech recognition system by Keyword Spotting. Nuvoton Website: www.nuvoton.com
