各位觀眾朋友大家好，今天非常高興藉這個機會跟各位介紹基於新唐M235x系列支持線上串流服務的智能箱解決方案，我們將以Google Cast為例，首先說明一下M235x系列的特色功能，M235x系列是新唐基於Cortex-M23 CPU帶TrustZone架構的IoT Security MCU，他能夠保護IoT裝置在IoT的使用場景下資料的安全以及方方面面安全的考量，我們今天會有實際的智能音箱線上串流音樂服務的操作說明，同時輔以我們的輔助資料說明線上認證的過程，讓我們現在開始。 我們用一個實際的範例來說明M235x系列如何在無線音箱上實現支持Google Cast的線上撥放，我們準備了一個支援Google Cast的無線音箱跟智能手機，同時把手機上的Youtube APP打開，因為音箱內建的M235x系列IC先前已經經過線上認證可以支援Google Cast服務，當我們透過Youtube撥放音樂時，聲音就會自動傳送到無線音箱，此時，可以透過音箱上的按鍵來調整音量，也可以透過手機上的操作來調整音量，這個線上播放的過程是合法而且十分的迅速，再者，透過適當的APP，一隻手機可以支持最多16個Google Cast Wireless Speaker，不同的地點，不同的音樂。 以上, 就是今天的教學影片，非常感謝各位的觀看，歡迎訂閱我們的頻道，如果有更多的需求，請我們聯繫，謝謝大家。 #zh-Hant #Application #Seminar #General - 【2021 Roadshow專區】 精彩內容：https://www.nuvoton.com/roadshow2021 - 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 聯絡我們：SalesSupport@nuvoton.com

Loudspeakers are highly nonlinear and time-variant systems. Signal distortion, heating, aging, climate and other external influences limit the maximum level and the quality of the reproduced sound. This video shows how Nuvoton smart amplifier can greatly improve the speaker performance and the sound quality by offering mechanical & thermal protection, automatic system alignment, active compensation of transducer nonlinearities, and active stabilization of the voice coil rest position based on the Klippel Controlled Sound (KCS) technology.

Hello everyone, I am Morgan, the principal engineer of Nuvoton Technology. Today, I will show you how to record and play audio with Mbed OS on NuMaker-IoT-M487 development board. Open Chrome browser, and enter the URL https://ide.mbed.com to use the Mbed Online Compiler. After log in, make sure that NuMaker-IoT-M487 board already selected in the upper right corner. 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 left of menu bar, a “Create new program” window will be displayed. You can see that the Platform has been set to NuMaker-IoT-M487. In the Template, select the "NuMaker audio playback" for this tutorial. Then click OK. Now you can see that the sample code has loaded on the page. The sample code has three functions: 1. Record 10 seconds sound and save to Micro SD card 2. Play sounds stored in Micro SD card 3. Loopback. Record sound and play it immediately. Click main.cpp to open it. Then scroll down to line 421. You can see the functions calls here. It set to loopback only. Let’s do a little modification. Hit a key on console to start record 10 seconds then play it, and then do loopback. printf("Press a key to start recording 10 seconds..."); getchar(); demo_record(); demo_play(); demo_loopback(); Save it and click “Compile” to build the code. Compilation takes a while, please wait. After the compilation is completed, “Success” will appear in the compile output window. The browser downloads the binary firmware file directly after a successful compiling. It will be saved in a default download folder. In Chrome, you can click download file and select “Show in folder”. Please plug an earphone commonly used for mobile phone in headphone jack on NuMaker-IoT-M487 board. For demonstration, we use a headphone splitter cable to connect a microphone and a speaker. Do not put the microphone and speaker too close to avoid feedback howling. Then connect the USB port to your computer and make sure the onboard LED lights up. Back to the folder you just download the binary firmware file (NuMaker-mbed-AudioPlayback-example.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 favorite terminal tool. Here we use Putty. Open the COMx port with 9600 baud rate. And no flow control settings. Then “Open” it. Press “Reset” on board to run the firmware again. Press a key on terminal to start record. Speak for about 10 seconds, then your voice will be played. That’s all for this tutorial. Thank you for watching. Welcome to subscribe to our channel.
