【emwin】使用鍵盤數據發送函數的注意事項

@2018-08-08

小記

　　鍵盤實現時，在發送鍵值時， 函數 GUI_SendKeyMsg(GUI_KEY_BACKSPACE, Pressed) 的參數 Pressed 在按鍵按下狀態的 case 語句后無 break，此方法參考至官方的模擬器中的鍵盤實例，加上 break 會導致鍵盤無響應結果

case ID_BUTTON_13: // Notifications sent by '<- -Button'
      switch(NCode) {
      case WM_NOTIFICATION_CLICKED:
        // USER START (Optionally insert code for reacting on notification message)
      
        Pressed = 1;
      
        // USER END
      case WM_NOTIFICATION_RELEASED:
        // USER START (Optionally insert code for reacting on notification message)
      
        GUI_SendKeyMsg(GUI_KEY_BACKSPACE, Pressed);
      
        // USER END
        break;
      // USER START (Optionally insert additional code for further notification handling)
      // USER END
      }
      break;
