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

介紹與說明 Nuvoton NuMicro ML56 電容式觸控按鍵電路板設計。 哈囉大家好！我是新唐 FAE Tim。 今天為大家介紹 ML56 電容式觸控按鍵電路板設計。 首先介紹觸控傳感器通道選擇。 #觸控傳感器通道 ML56 系列最多支援 14 個觸控傳感器通道。 #參考傳感器 建議選擇觸控傳感器通道 TK7 或 TK14 當作參考傳感器。 加大參考傳感器和其他信號之間的距離，以降低互相干擾的機會。 #屏蔽電極 將屏蔽電極圍繞在觸控傳感器周圍，可以有更好的信號品質和防水能力。 建議選擇觸控傳感器通道 TK0, TK4 或時脈輸出腳位 (P3.2/ P4.6/ P5.7) 當作屏蔽通道。 接著要說明 PCB 佈局規則。 #觸控按鍵形狀 建議傳感器面積為 10 x 10 mm，以實現良好的觸控按鍵靈敏度。 觸控傳感器的電極越大，外殼厚度可以越厚。 #參考傳感器 建議選擇觸控傳感器通道 TK7 或 TK14 當作參考傳感器。 加大參考傳感器和其他信號之間的距離，以降低互相干擾的機會。 一般情況下，建議使用直徑為 1 mm 大小的圓形電極。 #接地 建議觸控按鍵的走線具有良好的網地圍繞。 建議觸控按鍵下方要鋪網地。 鋪網地的規格為 6 mil 的走線和 50 mil 的網格。 #屏蔽電極 將屏蔽電極圍繞在觸控按鍵周圍，用於在觸控按鍵周圍提供同相位的信號。 網狀屏蔽電極的規格為 6 mil 的走線和 50 mil 的網格。 屏蔽電極區域到觸控按鍵周圍的寬度需要大於 10 mm。 #觸控按鍵外殼厚度 隨著外殼厚度的增加，觸控按鍵的靈敏度將降低。 觸控按鍵尺寸越大，外殼能做得越厚。 建議的觸控按鍵直徑尺寸與搭配的壓克力外殼厚度如表所示。 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

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
