介紹與說明 Nuvoton NuMicro ML56 電容式觸控按鍵防水與抗干擾。 哈囉大家好! 我是新唐 FAE Tim，今天為大家做 ML56 觸控按鍵防水與抗干擾介紹。 首先介紹 ML56 觸控按鍵防水與抗干擾的能力。 良好的防水能力，在 2 mm 深度的積水下觸控按鍵動作仍正常。 通過 IEC 61000-4-6 10 V 動態注入電流測試。 接著要說明 ML56 觸控按鍵的相關參數設定，先說明觸控靈敏度。 #Pulse Width (觸控按鍵感測脈衝寬度時間控制） 可以透過適當設定脈衝寬度來調整觸控按鍵的靈敏度，較短的脈衝寬度設定會帶來較差的靈敏度和較低的功耗，反之亦然。 接著說明觸控性能的穩定性之 1 #Times (觸控按鍵感測次數控制) 可以透過適當地設置 “次數” 來調整觸控按鍵原始數據的穩定性，“次數” 設置越短，原始數據的穩定性越差，功耗也越低，反之亦然。 觸控性能的穩定性之 2 #IIR (IIR 濾波器) IIR 濾波器可以控制當前原始數據與上一個原始數據的比率。 用戶可以啟用 IIR 濾波器以抗干擾。啟用 IIR 濾波器時，它將增加觸控響應時間。 觸控性能的穩定性之 3 #Debounce (觸控按鍵去抖動) 可以透過適當地設置去抖動，觸控按鍵進入 (開) 和釋放 (關) 偵測的去抖動次數來調整觸控按鍵的穩定性，較短的去抖動設置會帶來更快的觸控響應時間，反之亦然。 觸控性能的穩定性之 4 #Trace Baseline (基準線是透過 “校正” 所產生的) 觸控按鍵自動環境補償是一種演算法，該演算法可在啟動運作時自動追蹤基準線做環境變化補償，使觸控按鍵性能更加穩定。綜合上述的參數說明，以下為大家介紹防水與抗干擾的參數設定。 首先是 #防水參數設定。 良好的防水能力，在 2 mm 深度的積水下觸控按鍵動作仍正常。 觸控按鍵系統參數如表所示： Pulse Width = 500 ns Times = 128 接著是 #抗干擾性參數設定 通過 IEC 61000-4-6 10 V 動態注入電流測試。 觸控按鍵系統參數如表所示： Pulse Width = 2 us Times = 128 IIR New = 6, Old = 2 Debounce Entry = 1, Release = 1 接著我們使用 ML56 NuMaker Board 來為大家做實際操作展示 #觸控按鍵防水功能。手指先沾水，然後去觸摸觸控按鍵，反覆以上動作，可以看到觸控按鍵依舊正常動作，不受影響。 最後我們使用 ML56 NuMaker Board 來為大家做實際操作展示 #觸控按鍵抗干擾能力。先打開對講機，然後近距離干擾觸控按鍵，可以看到觸控按鍵依舊正常動作，不受影響。 以上是這次的教學影片, 謝謝大家! 如果您有任何問題，歡迎聯絡我們。 - 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/low-power-8051-series/ 聯絡我們： SalesSupport@nuvoton.com #Product #Learning #Basic #zh-Hant

Introduce the waterproof and noise immunity of ML56 touch key. Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you the waterproof and noise immunity of ML56 touch key. First introduce the waterproof and noise immunity of ML56 touch key. Good waterproof function, support finger touch with 2 mm depth water droplet. IEC 61000-4-6 conducted noise immunity (CNI) with 10 Vrms noise voltage. Next, we will explain the related parameter settings of the ML56 touch key, and first explain the touch sensitivity. #Pulse Width (Touch key sensing pulse width time control) Touch key sensitivity can be adjusted by setting Pulse Width properly, shorter Pulse Width setting comes with poor sensitivity and less power-consumption, vice versa. Then explain the stability of touch performance, Part 1. #Times (Touch key sensing times control) Touch key raw data stability can be adjusted by setting Times properly, shorter Times setting comes with poor raw data stability and less power-consumption, vice versa. Stability of touch performance, Part 2. #IIR (IIR filter) IIR filter can control the ratio of current raw data and previous one. User can enable IIR Filter to be against noise. It will increase the touch response time when enables IIR Filter. Stability of touch performance, Part 3. #Debounce (Touch key debounce) Touch key stability can be adjusted by setting Debounce properly, the debounce times for touch key entry (on) and release (off) detection, shorter Debounce setting comes with faster touch response time, vice versa. Stability of touch performance, Part 4. #Trace Baseline (Baseline is generated by “Calibration”) Touch key auto environment compensation is an algorithm that baseline tracking each touch key automatically at power-up and keeps compensating environment variation affects touch key performance during runtime. Based on the above parameter description, the following introduces the waterproof and noise immunity parameter settings. The first is waterproof parameter setting. Good waterproof function, support finger touch with 2 mm depth water droplet. Touch key system parameters are shown in the table Pulse Width = 500 ns Times = 128 Next is the noise immunity parameter setting IEC 61000-4-6 conducted noise immunity (CNI) with 10 Vrms noise voltage. Touch key system parameters are shown in the table. Pulse Width = 2 us Times = 128 IIR New = 6, Old = 2 Debounce Entry = 1, Release = 1 Then we use the ML56 NuMaker Board to show you the waterproof function of the touch key. Dip the finger in water first, and then touch the touch key. Repeat the above actions, we can see that the touch key still works normally and is not affected. Finally, we use the ML56 NuMaker Board to show you the noise immunity ability of the touch key. Turn on the walkie-talkie first, and then interfere with the touch key at close range, we can see that the touch key still operate normally and is not affected.

Hello! Everyone! I am Nuvoton FAE Tim. Today, I will show you ML56 Capacitive Touch Key PCB Design. First introduce the Touch Sensor Channel Selection. Touch Sensor Channels. ML56 series supports up to 14 touch sensor channels. #Reference Sensor It is recommended to select one reference sensor at touch sensor channel TK7 or TK14. Maximize the distance between the reference sensor and other signals to minimize crosstalk. #Shield Electrodes Put the shield electrode around the touch sensor to get better signal quality and waterproof capability. Recommended to select shield channel at touch TK0, TK4 or clock out pins (P3.2 / P4.6 / P5.7). Next, we will explain the PCB Layout Rules. #Touch Key Shapes Recommended to have a 10 x 10 mm sensor area for good touch key sensitivity. Larger touch sensor electrode work better for thicker cover. #Reference Sensor Recommended to assign the reference key at touch channel TK7 or TK14. Maximize the distance to other signals to minimize crosstalk. Round shape electrode with 1 mm diameter size is enough for normal case. #Ground Plane It is recommended that the traces of the touch key have a good hatched ground plane surround. It is recommended to have hatched ground plane under the touch keys. Hatched ground plane with 6 mil trace and 50 mil grid. #Shield Electrode Put touch keys with shield electrode around which provides the same phase signal around touch keys. Hatched shield electrode with 6 mil trace and 50 mil grid. Shield electrode area needs to keep filled around the touch key in greater than 10 mm width. Finally, explain the Touch Key Cover Thickness. As the cover thickness increases, the touch key sensitivities will decrease. Larger touch key size work better for thicker cover. Recommended touch key diameter size with difference acrylic cover thickness as shown in the table. That's all for today's video, thank you everyone!

介紹與說明 Nuvoton NuMicro ML56 電容式觸控按鍵基本原理和感應方法。 哈囉大家好! 我是新唐 FAE Tim，今天為大家介紹 ML56 電容式觸控按鍵技術。 首先介紹 #電容式觸控按鍵基本原理。 在沒有手指觸摸的傳感器的電容稱為 “寄生電容” CP 。 寄生電容是由傳感器 (包括傳感器，走線和過孔) 與系統中其他導體 (例如接地層，走線，產品機構或外殼中的任何金屬等) 之間的電場所產生的。 傳感器和手指之間的電容為 CF，傳感器的總電容 CT 是 CP 和 CF 之和。 接著要說明 ML56 #電容式觸控按鍵感應方法。 ML56 實現了兩個可變電容器組，用於向 CP (或 CT) 和 CR 注入電荷。 CR 是參考通道的寄生電容，在觸控按鍵校正之後，CP 和 CR 與 CB 和 CCB 保持平衡 (比較器輸出為 “低準位”) 。 手指觸摸在目前偵測的觸控按鍵，導致 CT = CP + CF，使比較器的負輸入端電壓低於正輸入端，並且比較器輸出為 “高準位”。 ML56 觸控按鍵控制器會將 CCB 增加到 CCB’，以使 CT 和 CR 再次達到平衡 (比較器輸出為 “低準位”)。透過檢查 CCB 和 CCB’ 之間的差異，可以做手指觸摸的偵測。 CCB 增加到 CCB’ 的數值與預定的觸控門檻值來做比較，演算法可以確定觸控按鍵處於 ON (觸摸) 狀態還是 OFF (無觸摸) 狀態。 以上是這次的教學影片, 謝謝大家！ 如果您有任何問題，歡迎聯絡我們。 - 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/low-power-8051-series/ 聯絡我們： SalesSupport@nuvoton.com #Product #Learning #Basic #zh-Hant

Hello everyone I am Chris, the Field Application Engineer from Nuvoton Technology. Today I will introduce the programming and debugging tool, called NuLink-Gang, and NuLink2-Pro. And I will show you in what kind of situation you can utilize the tools. During system development, Nuvoton provides three IDE interfaces: KEIL, IAR, and NuEclipse for user to develop source code. When programming the Chip, Nuvoton provides ICP programming Tool in PC and the debugger Nu-Link2-Pro for users to perform debugging and programming function. User who uses all of the Nuvoton Nu-Maker boards series can develop through the Nu-Link2-Me debugger and programmer; it’s attached to the board. During the mass-production stage, there are 2 modes for programming the target chip. One is online programming and the other is offline programming. At first, in online programming mode, user can use ICP programming Tool and a Nu-Link2-Pro to program a target chip. Besides, if it needs to program several chips at one times, the Nu-Link Command Tool supports program multiple develop board by several Nu-Link2-Pro. Nu-Link2-Pro also supports drag-and-drop Flash programming. User can intuitively complete the programming action. Nu-Link2-Pro In offline programming mode, user can pre-store the programming file in SPI flash, USB flash drive, or SD card. When user wants to program the target chip, pressing the programming button on Nu-Link2-Pro to complete the programming action. If it needs a large number of ICs to be programming, it recommends using the Nu-Link-Gang programmer. Nu-Link-Gang programmer can perform offline programming on four different chips at a time, significantly increasing the programming efficiency. Besides, Nu-Link-Gang programmer can also use the control bus to connect with an automatic programming machine for automatic programming. In the system upgrade, Nu-Link2-Pro also provides five standard communication interfaces such as SPI, I2C, UART, RS485, and CAN for transmission, which is convenient for users to upgrade the system. That’s all for the introduction of Nuvoton’s programming and debugging tool, NuLink-Gang, and NuLink2-Pro. Thank you for watching it. If you want to know more details, please contact us!

Hello everyone! I am Chris, the Field Application Engineer from Nuvoton Technology. Today, I will introduce how to run a simple sample code on NuMicro M251/M252 series microcontroller. First, we connect the M251/M252 NuMaker development Board to the computer. Then click the M251/M252 BSP folder, click the Sample Code folder, template folder, Keil folder, and finally open the Template project file. What we are going to do is running a simple GPIO Toggle LED Sample Code. Introduce the main program briefly. First, set GPIO PB14 to Output Mode. After writing a small loop, set PB14 to reverse. Finally, set CLK_SysTickDelay to 300,000 microseconds (uSec). Before Rebuild, we must add the GPIO Source Code to the Library, find the corresponding Source Code and load it, and press Rebuild after it is complete. After the Rebuild, press Load and program the Code into the IC. When programing is over, press the reset button on the development board to confirm whether the LED lights are flashing on the board. That’s all for the tutorial of running sample code. Thank you for watching it.
