-# Component: Button
-
-* This component defines a button as a well encapsulated object.
-* A button device is defined by:
-    * GPIO number on which the button is attached.
-    * Active level which decided by peripheral hardware.
-    * Trigger mode which decides whether to call serial trigger callback during pressing
-    * Serial threshold seconds which decides that serial trigger callback will be called after how many seconds' pressing
-* A button device can provide:
-    * One push event callback
-    * One release event callback
-    * One short-time tap event callback
-    * One serial trigger event callback
-    * Several long-time press event callback
-    We can set different jitter filters for all the events.
-    Once any of the long press callback is triggered, the short tap event will not be triggered.
-    These components are based on GPIO provided by ESP-IDF and soft timer provided by FreeRTOS.
-
-* To use the button device, you need to:
-    * create a button object returned by iot_button_create().
-    * Then hook different event callbacks to the button object.
-    * To free the object, you can call iot_button_delete to delete the button object and free the used memory.
-
-* Todo: Add hardware timer mode(because sometimes soft-timer callback function is limited)
-
-### NOTE:
-> All the event callback function are implemented by FreeRTOS soft timer APIs, the callback must follow the rule:
-
-
-
-```
-  Button callback functions execute in the context of the timer service task.
-  It is therefore essential that button callback functions never attempt to block.
-  For example, a button callback function must not call vTaskDelay(), vTaskDelayUntil(), or specify a non zero block time when accessing a queue or a semaphore.
-```
-
-> In addition:
-> You can adjust the following macros within FreeRTOS to adjust the stack depth/queue length/task priority of the timer service.
-
-
-```
-#define configUSE_TIMERS //enable soft-timer
-#define configTIMER_TASK_PRIORITY // priority of the timers service task
-#define configQueue_LENGTH // length of timer command queue
-#define configTIMER_TASK_STACK_DEPTH // stack depth of the soft-timer
-```

-# Component: Button
-
-* This component defines a button as a well encapsulated object.
-* A button device is defined by:
-    * GPIO number on which the button is attached.
-    * Active level which decided by peripheral hardware.
-    * Trigger mode which decides whether to call serial trigger callback during pressing
-    * Serial threshold seconds which decides that serial trigger callback will be called after how many seconds' pressing
-* A button device can provide:
-    * One push event callback
-    * One release event callback
-    * One short-time tap event callback
-    * One serial trigger event callback
-    * Several long-time press event callback
-    We can set different jitter filters for all the events.
-    Once any of the long press callback is triggered, the short tap event will not be triggered.
-    These components are based on GPIO provided by ESP-IDF and soft timer provided by FreeRTOS.
-
-* To use the button device, you need to:
-    * create a button object returned by iot_button_create().
-    * Then hook different event callbacks to the button object.
-    * To free the object, you can call iot_button_delete to delete the button object and free the used memory.
-
-* Todo: Add hardware timer mode(because sometimes soft-timer callback function is limited)
-
-### NOTE:
-> All the event callback function are implemented by FreeRTOS soft timer APIs, the callback must follow the rule:
-
-
-
-```
-  Button callback functions execute in the context of the timer service task.
-  It is therefore essential that button callback functions never attempt to block.
-  For example, a button callback function must not call vTaskDelay(), vTaskDelayUntil(), or specify a non zero block time when accessing a queue or a semaphore.
-```
-
-> In addition:
-> You can adjust the following macros within FreeRTOS to adjust the stack depth/queue length/task priority of the timer service.
-
-
-```
-#define configUSE_TIMERS //enable soft-timer
-#define configTIMER_TASK_PRIORITY // priority of the timers service task
-#define configQueue_LENGTH // length of timer command queue
-#define configTIMER_TASK_STACK_DEPTH // stack depth of the soft-timer
-```
