Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you ML56 Capacitive Touch Key Technology. First introduce the Capacitive Touch Key Fundamentals. The capacitance of the sensor without a finger touch is called as “parasitic capacitance”, CP. Parasitic capacitance results from the electric field between the sensor (including the sensor pad and traces) and other conductors in the system such as the ground planes, traces, any metal in the product’s chassis or enclosure, etc. The capacitance between the sensor pad and the finger is CF. The total capacitance CT of the sensor is the sum of CP and CF. Next, we will explain the ML56 Capacitive Touch Key Sensing Method. ML56 implements two switching capacitor banks for injecting charges to CP (or CT) and CR. CR is the parasitic capacitance of reference channel. After touch key calibration, CP and CR are balanced with CB and CCB (comparator output is “low”). Touch the sensing touch key which makes CT = CP + CF Now the negative input terminal voltage of the comparator is lower than positive side and comparator output is “high”. ML56 touch key controller will increase CCB to CCB’ to balance CT and CR again (comparator output is “low”). A finger touch can be detected by checking the difference of CCB and CCB’. By comparing the CCB’ shift level from CCB, the steady state to a predetermined threshold, the algorithm can determine whether the touch key is in ON (Touch) or OFF (No Touch) state.

Nuvoton provides a development tool for capacitive Touch Sensors. The best feature of the calibration tool is that it uses the GUI to configure and tune your design automatically. Besides, the tool can export the configuration parameters and import them to another. Not only can greatly shorten the development time of developers, but also shorten the time for mass production. This video will introduce how to use this development tool and the definition of parameter. - For more information, please visit Nuvoton Technology Website: https://bit.ly/3hVdcmC Buy now: https://direct.nuvoton.com/tw/low-power-8051-series/ Contact us: SalesSupport@nuvoton.comon.com #Product #Learning #Basic #en

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 connect to AWS IoT service using MbedOS on NuMaker-IoT-M487 development board The sample code is on GitHub, the URL is https://github.com/OpenNuvoton/Mbed-to-AWS-IoT To avoid typos, use keyword “OpenNuvoton” to search on google. Find the Nuvoton on GitHub, and click it On the Nuvoton GitHub page, use AWS as keyword to search the sample code: Mbed-to-AWS-IoT Right click to copy the URL for later use. Then enter the URL https://ide.mbed.com After log in, make sure the NuMaker-IoT-M487 board has selected in the upper right corner. If not, please refer Nuvoton IoT Tutorial series “Get Started with Mbed OS”. There is detailed description of how to add a board. Click the “Import” on the left of menu bar. In the “Import Wizard”, click “Click here” Please paste or key in the sample code URL to “Source URL:”, Select Import as “Program” Click “Import Name”, the project name “Mbed-to-AWS-IoT” will be filled automatically. Then click “Import”. After sample code imported, click “mbed_app.json” to open it. To use Wi-Fi, you have to configure SSID and password to match your Wi-Fi AP setting. In NuMaker_IOT_M487 session of mbed_app.json file, find the “wifi-ssid” to set your SSID. It is at line 44. And then set password to “wifi-password”. It is at line 45. Save it and click “Compile” to build the code. It takes time to compile code, please wait. You need an AWS account to use AWS IoT Core service. To create a thing, a policy, and certificates, then put the certificate to MQTT_server_setting.h file in the sample code. The sample code has included a certificate provided by Nuvoton for test only, so that you can quickly operate this example. If you don’t have an AWS account, it is recommended that you apply for an account and use your certificates in the example to observe the connection status on AWS IoT console page. After 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”. Then we connect the NuMaker-IoT-M487 USB port to your computer. Please find the virtual COM port assigned for NuMaker-IoT-M487 in Device Manager. In the tutorial, the “Nu-Link Virtual Com Port” is COMx. Then use your favorite terminal tool. Here we use Putty. Open the COMx port with 115200 baud rate. And no flow control settings. Then “Open” it. Back to the folder you just download the binary firmware file (Mbed-to-AWS-IoT.NUMAKER_IOT_M487.bin). Drag and drop the file to NuMicro MCU drive. You will see the copying progress dialog box. You can see the messages on terminal. The device has acquired IP address from Wi-Fi AP, then successfully connect to AWS IoT and subscribe a topic. Then press button (SW2) on board to send a message. You can see the message published to server and received a message from server. That’s all for this tutorial. Thank you for watching. Welcome to subscribe to our channel.
