具体实施方式
以下将配合附图及实施例来详细说明本发明的实施方式，藉此对本发明如何应用技术手段来解决技术问题并达成技术功效的实现过程能充分理解并据以实施。
随着电子技术的日趋成熟，电子设备具有的功能越来越多，用户与电子设备的交互通常是通过按键来实现的。现有技术中，在电子设备设置的按键例如智能音箱或智能手环设置的按键，针对每一个按键仅设置一个按键功能。按键检测通常需要硬件电路与软件程序同步来保证按键的可靠性及检测效率。硬件电路的设计需要根据实际的按键数量以及对应的MCU(Micro Control Unit，微处理器)的引脚数量确定的。当按键数量较少时可以将按键通过I/O(input/output，输入输出端口)直接连接到MCU的引脚上，但当按键数量较多时，就无法保证每一个按键能够直接连接到MCU的引脚上，这就需要设计额外的硬件电路，实现每一个按键与MCU的连接。由于设计的硬件电路仅针对特定的功能需求，在进行软件研发时也必须针对设计的硬件电路进行软件设计，才能保证按键的可靠性及检测效率。
但这种按键检测方法，硬件电路设计复杂，不仅导致硬件电路设计成本增加，由于软件程序是针对特定需求的硬件电路设计的，因此一但电子设备按键设计需求发生变更时，原有的按键检测方法就不再适用，需要重新对按键的硬件电路和软件程序针对变更的需求进行设计，这也导致的软件程序的可移植性较差，增加了开发成本，增加了开发时间。
为了解决硬件电路设计复杂，导致硬件电路设计成本增加，且开发周期较长的技术问题，发明人经过一系列研究提出了本发明的技术方案。本发明提供了一种按键配置方法、一种按键运行方法、装置及设备，所述方法应用与电子设备中，所述电子设备的按键与控制组件的引脚一一对应连接，不需要额外设计复杂的硬件电路。通过确定每一个按键对应的引脚信息，建立所述每一个按键的不同被触发状态与其对应引脚的电平的不同变化状态的对应关系。确定所述每一个按键的不同被触发状态分别对应的按键功能函数，基于所述每一个按键对应的引脚信息以及所述每一个按键的不同被触发状态分别对应的按键功能函数，生成按键执行程序。并通过检测任一个按键对应的引脚的电平的当前变化状态，确定当前变化状态对应的当前被触发状态。基于按键执行程序查找所述当前被触发状态对应的按键功能函数，并执行所述按键功能函数，从而实现该按键对应的按键功能。本发明通过模块化设计按键执行程序，使得按键执行程序可移植性高，降低硬件电路设计的复杂度，降低了开发成本，缩短了开发周期。
下面将结合附图对本发明技术方案进行详细描述。
图1是本发明实施例提供的一种按键配置方法的一个实施例的流程图，所述电子设备的 按键与控制组件的引脚一一对应连接。
该方法可以包括：
101：确定每一个按键对应的引脚信息。
本发明中，为了简化硬件电路设计，需要根据按键数量及按键功能需求进行配置。首先通过硬件电路将每一个按键与控制组件中的引脚一一对应连接。其中，所述引脚信息包括按键连接控制组件中的引脚对应的端口类型及引脚号。
所述控制组件可以是MCU(Micro Control Unit，微控制单元)或处理器。因此硬件电路连接简单，不需要额外设计复杂的硬件电路实现每一个按键与处理组件的连接，大大降低了硬件电路的设计成本。
102：建立所述每一个按键的不同被触发状态与其对应引脚的电平的不同变化状态的对应关系。
其中，所述按键的被触发状态可以包括单击状态、双击状态或长按状态。当任一个按键被按下时，均会引起对应的引脚的电平状态发生变化，不同的被触发状态引起的电平的变化状态不同。通过建立每一个按键的不同被触发状态对应的引脚的电平的变化状态的对应关系，从而可通过检测每一个按键对应的引脚的电平的变化状态确定每一个按键对应的被触发状态。
103：确定所述每一个按键的不同被触发状态分别对应的按键功能函数。
104：基于所述每一个按键对应的引脚信息以及所述每一个按键的不同被触发状态分别对应的按键功能函数，生成按键执行程序。
其中，所述按键功能函数预先建立在并存储在与所述控制组件连接的存储器中，并通过确定每一个按键的不同被触发状态分别对应的按键功能函数，使得所述每一个按键的按键执行程序用于被执行以实现所述每一个按键的任一被触发状态发生时对应的按键功能；所述每一个按键的任一被触发状态基于所述每一个按键连接的引脚的电平的变化状态以及所述对应关系确定。
可选地，在某些实施例中，所述基于所述每一个按键对应的引脚信息以及所述每一个按键的不同被触发状态分别对应的按键功能函数，生成按键执行程序包括：
定义所述按键执行程序的结构体；所述结构体至少包括引脚信息以及多个被触发状态；
按照每一个按键连接的引脚信息以及所述每一个按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述每一个按键的按键执行代码；
根据至少一个按键的按键执行代码，生成按键执行程序。
可选地，本发明采用模块化设计需求构建所述按键执行程序。
具体是，首先通过定义键执行程序的结构体。所述结构体，定义了键执行程序的结构及含义。
例如，可以定义为：
Figure PCTCN2017108085-appb-000001
在该结构体定义的基础上，按照待测试按键连接的引脚信息以及所述待测试按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述任一按键的执行代码，并根据至少一个按键的执行代码，生成按键执行程序。
例如，某一电子设备对应四个按键，包括：静音按键、上一首按键、下一首按键及电源按键。其中，静音按键单击时可以实现设备静音功能，长按时可以实现设备的联网功能；上一首按键单击时单击实现播放-暂停功能，长按时实现播放上一首歌曲的功能；下一首按键单击或长按时实现播放下一首歌曲的功能；电源按键单击时实现语音唤醒功能，长按是实现开机或关机功能。生成四个按键的按键执行程序如下：
#define KEY_NR  (4)    //按键个数为4的按键执行程序
struct Key keys[KEY_NR]＝
{
{KEY_MUTE_GPIO_Port,KEY_MUTE_Pin,mute_hook,dummy_hook,set_up_hook},
//定义了静音按键的端口号，引脚号，单击对应静音功能函数，双击对应为空，长按对应
联网功能函数
{KEY_PRE_GPIO_Port,KEY_PRE_Pin,paly_pause_hook,dummy_hook,previous_hook},
//定义了上一首按键的端口号，引脚号，单击对应播放暂停功能函数，双击对应为空，长
按对应上一首功能函数
{KEY_NEXT_GPIO_Port,KEY_NEXT_Pin,next_hook,dummy_hook,next_hook},
//定义了下一首按键的端口号，引脚号，单击对应下一首功能函数，双击对应为空，长
按对应下一首功能函数
{KEY_POWER_GPIO_Port,KEY_POWER_Pin,hot_word_hook,dummy_hook,power_hook},
//定义了电源按键的端口号，引脚号，单击对应语音唤醒功能函数，双击对应为空，长按
对应开机/关机功能函数
}；
可见，按键执行程序定义的4个按键中的每一个函数根据被触发状态，分别对应一个功能函数，当然如果设定的功能函数比较少，可以设定所述任一个按键的被触发状态对应的功能函数为空。
可选地，在某些实施例中，所述按照每一个按键连接的引脚信息以及所述每一个按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述每一个按键的按键执行代码之后，还包括：
接收更新请求；
根据所述更新请求，更新所述按键执行程序中待更新按键执行代码。
可选地，在某些实施例中，所述根据所述更新请求，更新所述按键执行程序中待更新按键的执行代码可以包括：
更新请求为删除请求，删除所述删除请求对应的所述任一按键的按键执行代码；
更新请求为修改请求，修改所述按键执行程序中待更新按键的执行代码中的引脚信息和/或任一按键功能函数；
更新请求为增加请求时，按照所述增加请求中的待更新按键的引脚信息以及所述待更新按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述待更新按键的按键执行代码。
因此，当按键的硬件连接设计或按键功能需要进行更新时，不需要修改模块化按键执行程序，仅需要根据按键设计的需求，修改按键执行程序即可。
当电子设备中按键减少时，即可直接从按键执行程序中，删除该按键对应的初始化代码；当任一按键的被触发状态对应的按键功能更改时，只需要更新按键执行程序中该按键对应的初始代码，将更新的功能函数替换原始的功能函数即可；当需要增加新的按键时，只需要根据增加请求中的待增加按键的引脚信息以及所述待更新按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述待更新按键的按键执行代码，将该按键执行代码添加到按键执行程序中即可。
例如，当硬件电路需要新增一个待更新按键，当该待更新按键单击时实现电子设备的系统的更新，长按时实现对更新的系统进行校验，验证是否更新完成。此时按键增加为5个，按键执行程序更新如下：
#define KEY_NR  (5)    //按键个数为5的按键执行程序
struct Key keys[KEY_NR]＝
{
{KEY_UPDATE_GPIO_Port,KEY_UPDATE_Pin,update_hook,dummy_hook,check_hook},
//定义了新增更新按键的端口号，引脚号，单击对应更新功能函数，双击对应为空，长按
对应为校验功能函数
{KEY_MUTE_GPIO_Port,KEY_MUTE_Pin,mute_hook,dummy_hook,set_up_hook},
{KEY_PRE_GPIO_Port,KEY_PRE_Pin,paly_pause_hook,dummy_hook,previous_hook},
{KEY_NEXT_GPIO_Port,KEY_NEXT_Pin,next_hook,dummy_hook,next_hook},
{KEY_POWER_GPIO_Port,KEY_POWER_Pin,hot_word_hook,dummy_hook,power_hook},
}；
同样，还可以修改每一按键的被触发状态对应的功能，例如，对静音按键及上一首按键的单击时实现的功能进行更新，只需修改调用的功能函数即可，具有4个按键(按键功能发生变化)的按键执行程序更新如下：
Figure PCTCN2017108085-appb-000002
本实施例中，通过基于按键结构体配置的按键执行程序，实现了对单一物理按键的单击、双击、长按或连续按不同被触发状态配置多种按键功能，并可根据设备更新需求对该按键执行程序进行更新或修改，实现按键的添加、删除以及功能修改的不同需求，使按键执行程序可以适用于不同的硬件电路，可移植性高，且由于一个按键可以实现多个按键功能，因此大大减少了按键数量，从而降低硬件电路设计的复杂度，可以大大降低了开发成本，缩短了开发周期。
图2是本发明实施例提供的一种按键运行方法的一个实施例的流程图，所述电子设备的按键与控制组件的引脚一一对应连接。
该方法可以包括：
201：检测任一个按键对应的引脚的电平的当前变化状态。
可选地，所述每一个按键通过I/O(input/output，输入输出端口)线与处理组件的引脚一 一对应连接，当任一按键被触发后，会引起处理组件相应引脚电平的变化，当该按键被按下时，相应的引脚的电平由A(高电平)变为B(低电平)；当该按键被抬起时，相应的引脚的电平由B(低电平)变为A(高电平)。
本发明中，可以通过20ms的定时，轮询检测每一个按键对应引脚的电平变化状态。
202：基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态。
因此基于任一个按键对应引脚的电平的变化状态，即可确定所述任一个按键的被触发状态。其中，所述按键的被触发状态根据用户的触发情况可以包括：单击、双击、长按或连续按。
203：基于按键执行程序查找所述当前被触发状态对应的按键功能函数，并执行所述按键功能函数。
可选地，在某些实施例中，所述基于按键执行程序查找所述当前被触发状态对应的按键功能函数，并执行所述按键功能函数包括：
调用按键执行程序查找被触发状态对应的按键功能函数，并执行所述按键功能函数。
所述按键执行程序定义了每一按键连接的引脚以及每一按键的不同被触发状态对应按键功能函数。
可选地，为了避免按键因外界干扰引起的“抖动”提高按键的电平变化状态的检测的成功率，需要预先对按键进行“去抖动”。所述外界干扰引起的按键“抖动”，可以是由于设备移动过程中引起的按键“抖动”，或者由于用户误触发按键引起的按键“抖动”。
可选地，在某些实施例中，所述基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态包括：
判断所述当前变化状态是否是有效变化状态；
如果是，基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态；
如果否，重新检测任一个按键对应的引脚的电平的当前变化状态。
可选地，所述判断所述变化状态是否为有效变化状态，可以通过20ms定时进行按键对应引脚变化状态的检测。通常按键“抖动”引起的相应引脚电平状态的变化的持续时间较短，通过20ms轮询检测，需要当检测到该引脚的电平由A变化到B时，经过3次20ms定时轮询，检测到该引脚的电平状态仍处于B状态，则该次变化状态为有效变化状态；如果经过3次20ms定时轮询后，检测到该引脚电平状态已经由B变化到A，则判断该变化状态为无效变化状态，该按键为误触发引起的状态变化，因此不需要执行相应按键功能。
可选地，在某些实施例中，所述被触发状态包括单击状态、双击状态或长按状态；
所述基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态包括：
如果基于所述变化状态判定所述任一个按键被触发后的持续时间达到第一预设时间，确定所述被触发状态为长按状态；
如果基于所述变换状态判定所述任一个按键被抬起后第二预设时间内是否再次被触发，确定所述被触发状态为双击状态；
如果基于所述变换状态判定所述任一个按键被出发后的持续时间未达到第一预设时长且在所述任一个按键被抬起后的第二预设时间内未被再次触发，确定所述被触发状态为单击状态。
可选地，按键检测程序最重要就是要检测按键的被触发状态，为了保证检测的准确性，可以通过20ms的定时轮询，判断变化状态的持续时间。
当任一个按键被按下后，对应引脚的电平状态由A变化到B，通过20ms定时任务判断B状态持续的时间，具体持续时间可以通过计数器对每次轮询进行计数，当轮询时检测该电平为B状态，则计数器加1。长按和连续按都是通过检测B状态持续时间进行判断。如果B状态持续时间达到300ms时，即可判断该按键的被触发状态为长按或连续按。
连续按为在长按该按键时，可以连续地多次触发该按键对应的按键功能，例如音量增加或音量减少键，即可以通过长按不断触发该按键增加或减少设备的音量。
如果该按键不满足长按条件时，继续判断该按键是否为单击或双击的被触发状态。其中，单击或双击需要在按键抬起后进行检测，当任一个按键触发后产生有效的变化状态之后，按键抬起，如果在50ms内再次按下即判断为双击，如果50ms内按键为被再次按下即判断为单击。具体为，该按键对应的引脚的电平变化状态为，由A变化到B后，再由B变化到A，此时判断由B变化到A时间隔是时间是否小于或等于50ms，如果满足，则判断该按键的被触发状态为双击，如果不满足则判断该按键的被触发状态为单击。
当通过按键的引脚的电平的状态变化检测确定该按键的被触发状态后，将检测结果通知处理组件调用所述按键执行程序，基于按键执行程序查找该按键的被触发状态对应的功能函数，并通过处理组件调用并执行相应的功能函数，以确定按键对应的功能。并在执行该按键功能函数后初始化该按键执行程序，等待该按键再次被触发后检测该按键的被触发状态。
本实施例的方法，可以适用于实现电子设备的按键功能。所述电子设备可以是设置有物理按键的运动手表或音箱。
可选地，在一个实际应用中，所述电子设备中设置了存储有图1实施例所述按键执行程 序，所述电子设备中的每一个按键通过I/O线与处理组件的引脚一一对应连接，当任一按键被触发后，会引起处理组件相应引脚的电平的变化。通过设定的20ms定时实时检测任一个按键对应的引脚的电平的当前变化状态。当该设备的任一按键被按下时，基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态。并通过处理组件调用所述按键执行程序查找所述当前被触发状态对应的按键功能函数，并执行所述按键功能函数，从而实现该按键对应的相应按键功能。
例如，该设备中的某一按键的单击为静音功能，当检测到该按键被触发并引起该按键对应引脚的电平的变化后，根据该引脚的电平的变化状态确定该按键的被触发状态为单击，然后基于按键执行程序查找到该按键单击状态对应的功能函数为静音功能函数，此时处理组件执行静音功能函数，从而实现该电子设备中该按键的静音功能。
本实施例中，通过检测按键对应引脚的电平的变化状态的是否为有效变化状态，可以去除按键误触发或外界干扰引起的按键的“抖动”，大大提高了按键的被触发状态的检测成功率。且通过定时轮询检测按键对应引脚的变化状态，可以准确地检测出按键的被触发状态，并通过处理组件调用按键执行程序，查找并执行该按键被触发状态对应的功能函数从而实现该按键对应的按键功能，从而大大提高了按键检测的有效率和准确率。
可选地，在生产制造电子设备时，还可以基于图1实施例所述的按键配置方法用于对电子设备的按键功能的检测。
可选地，还可以包括，一种按键件检测方法，所述电子设备的按键与控制组件的引脚一一对应连接。
所述方法包括：
检测任一个按键对应的引脚的电平的当前变化状态。
可选地，所述每一个按键通过I/O(input/output，输入输出端口)线与处理组件的引脚一一对应连接，当任一按键被触发后，会引起处理组件相应引脚电平的变化，当该按键被按下时，相应的引脚的电平由A(高电平)变为B(低电平)；当该按键被抬起时，相应的引脚的电平由B(低电平)变为A(高电平)。
本发明中，可以通过20ms的定时，轮询检测每一个按键对应引脚的电平变化状态。
基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态。
因此基于任一个按键对应引脚的电平的变化状态，即可确定所述任一个按键的被触发状态。其中，所述按键的被触发状态根据用户的触发情况可以包括：单击、双击、长按或连续按。
基于按键执行程序查找所述当前被触发状态对应的按键功能函数，并执行所述按键功能函数。
根据所述按键功能函数的执行结果，检测所述任一按键的被触发状态对应的按键功能是否正确。
在一个实际应用中，在基于图1实施例构建了按键执行程序之后，为了检测硬件电路与按键执行程序是否匹配有误，需要进行按键功能的检测。通过触发每一个按键的不同的被触发状态检测控制组件响应每一个按键的被触发状态后执行功能函数的执行结果是否与每一个按键不同被触发状态设定的功能相同。如果相同则所述任一按键的被触发状态对应的按键功能正确，如果不同，则可以基于图1实施例中所述的方法，对按键执行程序进行修改，从而完成按键功能的检测。
本实施例中，通过根据所述按键功能函数的执行结果，可以有效地检测每一个按键的不同被触发状态对应的按键功能是否正确，并实现根据按键检测结果修改相应的按键执行程序，大大提高了电子设备中按键功能的检测效率。
图3是本发明实施例的一种按键配置装置的一个实施例的结构示意图。所述电子设备的按键与控制组件的引脚一一对应连接；
所述装置可以包括：
第一确定模块301，用于确定每一个按键对应的引脚信息。
本发明中，为了简化硬件电路设计，需要根据按键数量及按键功能需求进行配置。首先通过硬件电路将每一个按键与控制组件中的引脚一一对应连接。其中，所述引脚信息包括按键连接控制组件中的引脚对应的端口类型及引脚号。
所述控制组件可以是MCU(Micro Control Unit，微控制单元)或处理器。因此硬件电路连接简单，不需要额外设计复杂的硬件电路实现每一个按键与处理组件的连接，大大降低了硬件电路的设计成本。
匹配模块302，用于建立所述每一个按键的不同被触发状态与其对应引脚的电平的不同变化状态的对应关系。
其中，所述按键的被触发状态可以包括单击状态、双击状态或长按状态。当任一个按键被按下时，均会引起对应的引脚的电平状态发生变化，不同的被触发状态引起的电平的变化状态不同。通过建立每一个按键的不同被触发状态对应的引脚的电平的变化状态的对应关系，从而可通过检测每一个按键对应的引脚的电平的变化状态确定每一个按键对应的被触发状态。
第二确定模块303，用于确定所述每一个按键的不同被触发状态分别对应的按键功能函 数。
生成模块304，用于基于所述每一个按键对应的引脚信息以及所述每一个按键的不同被触发状态分别对应的按键功能函数，生成按键执行程序。
所述每一个按键的按键执行程序用于被执行以实现所述每一个按键的任一被触发状态发生时对应的按键功能；所述每一个按键的任一被触发状态基于所述每一个按键连接的引脚的电平的变化状态以及所述对应关系确定。
其中，所述按键功能函数预先建立在并存储在与所述控制组件连接的存储器中，并通过确定每一个按键的不同被触发状态分别对应的按键功能函数，使得所述每一个按键的按键执行程序用于被执行以实现所述每一个按键的任一被触发状态发生时对应的按键功能；所述每一个按键的任一被触发状态基于所述每一个按键连接的引脚的电平的变化状态以及所述对应关系确定。
可选地，在某些实施例中，所述生成模块304可以包括：
定义单元，用于定义所述按键执行程序的结构体。
其中，所述结构体至少包括引脚信息以及多个被触发状态。
代码构建单元，用于按照每一个按键连接的引脚信息以及所述每一个按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述每一个按键的按键执行代码。
程序生成单元，用于根据至少一个按键的按键执行代码，生成按键执行程序。
可选地，本发明采用模块化设计需求构建所述按键执行程序。
具体是，首先通过定义键执行程序的结构体。所述结构体，定义了键执行程序的结构及含义。
例如，可以定义为：
Figure PCTCN2017108085-appb-000003
在该结构体定义的基础上，按照待测试按键连接的引脚信息以及所述待测试按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述任一按键的执行代码，并根据至少一个按键的执行代码，生成按键执行程序。
例如，某一电子设备对应四个按键，包括：静音按键、上一首按键、下一首按键及电源按键。其中，静音按键单击时可以实现设备静音功能，长按时可以实现设备的联网功能；上一首按键单击时单击实现播放-暂停功能，长按时实现播放上一首歌曲的功能；下一首按键单击或长按时实现播放下一首歌曲的功能；电源按键单击时实现语音唤醒功能，长按是实现开机或关机功能。生成四个按键的按键执行程序如下：
#define KEY_NR   (4)     //按键个数为4的按键执行程序
struct Key keys[KEY_NR]＝
{
{KEY_MUTE_GPIO_Port,KEY_MUTE_Pin,mute_hook,dummy_hook,set_up_hook},
//定义了静音按键的端口号，引脚号，单击对应静音功能函数，双击对应为空，长按对应
联网功能函数
{KEY_PRE_GPIO_Port,KEY_PRE_Pin,paly_pause_hook,dummy_hook,previous_hook},
//定义了上一首按键的端口号，引脚号，单击对应播放暂停功能函数，双击对应为空，长
按对应上一首功能函数
{KEY_NEXT_GPIO_Port,KEY_NEXT_Pin,next_hook,dummy_hook,next_hook},
//定义了下一首按键的端口号，引脚号，单击对应下一首功能函数，双击对应为空，长
按对应下一首功能函数
{KEY_POWER_GPIO_Port,KEY_POWER_Pin,hot_word_hook,dummy_hook,power_hook},
//定义了电源按键的端口号，引脚号，单击对应语音唤醒功能函数，双击对应为空，长按
对应开机/关机功能函数
}；
可见，按键执行程序定义的4个按键中的每一个函数根据被触发状态，分别对应一个功能函数，当然如果设定的功能函数比较少，可以设定所述任一个按键的被触发状态对应的功能函数为空。
可选地，在某些实施例中，所述代码构建单元之后，还可以包括：
接收单元，用于接收更新请求；
更新单元，用于根据所述更新请求，更新所述按键执行程序中待更新按键执行代码。
可选地，在某些实施例中，所述更新单元具体可以用于：
更新请求为删除请求，删除所述删除请求对应的所述任一按键的按键执行代码；
更新请求为修改请求，修改所述按键执行程序中待更新按键的执行代码中的引脚信息和/或任一按键功能函数；
更新请求为增加请求时，按照所述增加请求中的待更新按键的引脚信息以及所述待更新 按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述待更新按键的按键执行代码。
因此，当按键的硬件连接设计或按键功能需要进行更新时，不需要修改模块化按键执行程序，仅需要根据按键设计的需求，修改按键执行程序即可。
当电子设备中按键减少时，即可直接从按键执行程序中，删除该按键对应的初始化代码；当任一按键的被触发状态对应的按键功能更改时，只需要更新按键执行程序中该按键对应的初始代码，将更新的功能函数替换原始的功能函数即可；当需要增加新的按键时，只需要根据增加请求中的待增加按键的引脚信息以及所述待更新按键的不同被触发状态对应的按键功能函数，基于所述结构体构建所述待更新按键的按键执行代码，将该按键执行代码添加到按键执行程序中即可。
例如，当硬件电路需要新增一个待更新按键，当该待更新按键单击时实现电子设备的系统的更新，长按时实现对更新的系统进行校验，验证是否更新完成。此时按键增加为5个，按键执行程序更新如下：
#define KEY_NR  (5)    //按键个数为5的按键执行程序
struct Key keys[KEY_NR]＝
{
{KEY_UPDATE_GPIO_Port,KEY_UPDATE_Pin,update_hook,dummy_hook,check_hook},
//定义了新增更新按键的端口号，引脚号，单击对应更新功能函数，双击对应为空，长按
对应为校验功能函数
{KEY_MUTE_GPIO_Port,KEY_MUTE_Pin,mute_hook,dummy_hook,set_up_hook},
{KEY_PRE_GPIO_Port,KEY_PRE_Pin,paly_pause_hook,dummy_hook,previous_hook},
{KEY_NEXT_GPIO_Port,KEY_NEXT_Pin,next_hook,dummy_hook,next_hook},
{KEY_POWER_GPIO_Port,KEY_POWER_Pin,hot_word_hook,dummy_hook,power_hook},
}；
同样，还可以修改每一按键的被触发状态对应的功能，例如，对静音按键及上一首按键的单击时实现的功能进行更新，只需修改调用的功能函数即可，具有4个按键(按键功能发生变化)的按键执行程序更新如下：
Figure PCTCN2017108085-appb-000004
Figure PCTCN2017108085-appb-000005
本实施例中，通过基于按键结构体配置的按键执行程序，实现了对单一物理按键的单击、双击、长按或连续按不同被触发状态配置多种按键功能，并可根据设备更新需求对该按键执行程序进行更新或修改，实现按键的添加、删除以及功能修改的不同需求，使按键执行程序可以适用于不同的硬件电路，可移植性高，且由于一个按键可以实现多个按键功能，因此大大减少了按键数量，从而降低硬件电路设计的复杂度，可以大大降低了开发成本低，缩短了开发周期。
图4是本发明实施例的一种按键运行装置的一个实施例的结构示意图，所述电子设备的按键与控制组件的引脚一一对应连接；
所述装置可以包括：
第一检测模块401，用于检测任一个按键对应的引脚的电平的当前变化状态。
可选地，所述每一个按键通过I/O(input/output，输入输出端口)线与处理组件的引脚一一对应连接，当任一按键被触发后，会引起处理组件相应引脚电平的变化，当该按键被按下时，相应的引脚的电平由A(高电平)变为B(低电平)；当该按键被抬起时，相应的引脚的电平由B(低电平)变为A(高电平)。
本发明中，可以通过20ms的定时，轮询检测每一个按键对应引脚的电平变化状态。
第三确定模块402，用于基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态。
因此基于任一个按键对应引脚的电平的变化状态，即可确定所述任一个按键的被触发状态。其中，所述按键的被触发状态根据用户的触发情况可以包括：单击、双击、长按或连续按。
第一查找模块403，用于基于按键执行代码查找所述当前被触发状态对应的按键功能函数。
第一执行模块404，用于执行所述按键功能函数。
可选地，在某些实施例中，所述查找模块403具体可以用于：
调用按键执行程序查找被触发状态对应的按键功能函数，并执行所述按键功能函数。
所述按键执行程序定义了每一按键连接的引脚以及每一按键的不同被触发状态对应按键 功能函数。
可选地，为了避免按键因外界干扰引起的“抖动”提高按键的电平变化状态的检测的成功率，需要预先对按键进行“去抖动”。所述外界干扰引起的按键“抖动”，可以是由于设备移动过程中引起的按键“抖动”，或者由于用户误触发按键引起的按键“抖动”。
可选地，在某些实施例中，所述第三确定模块402具体可以用于：
判断所述当前变化状态是否是有效变化状态；
如果是，基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态；
如果否，重新检测任一个按键对应的引脚的电平的当前变化状态。
可选地，所述判断所述变化状态是否为有效变化状态，可以通过20ms定时进行按键对应引脚变化状态的检测。通常按键“抖动”引起的相应引脚电平状态的变化的持续时间较短，通过20ms轮询检测，需要当检测到该引脚的电平由A变化到B时，经过3次20ms定时轮询，检测到该引脚的电平状态仍处于B状态，则该次变化状态为有效变化状态；如果经过3次20ms定时轮询后，检测到该引脚电平状态已经由B变化到A，则判断该变化状态为无效变化状态，该按键为误触发引起的状态变化，因此不需要执行相应按键功能。
可选地，在某些实施例中，所述被触发状态包括单击状态、双击状态或长按状态；
所述第三确定模块402具体可以用于：
如果基于所述变化状态判定所述任一个按键被触发后的持续时间达到第一预设时间，确定所述被触发状态为长按状态；
如果基于所述变换状态判定所述任一个按键被抬起后第二预设时间内是否再次被触发，确定所述被触发状态为双击状态；
如果基于所述变换状态判定所述任一个按键被出发后的持续时间未达到第一预设时长且在所述任一个按键被抬起后的第二预设时间内未被再次触发，确定所述被触发状态为单击状态。
可选地，按键检测程序最重要就是要检测按键的被触发状态，为了保证检测的准确性，可以通过20ms的定时轮询，判断变化状态的持续时间。
当任一个按键被按下后，对应引脚的电平状态由A变化到B，通过20ms定时任务判断B状态持续的时间，具体持续时间可以通过计数器对每次轮询进行计数，当轮询时检测该电平为B状态，则计数器加1。长按和连续按都是通过检测B状态持续时间进行判断。如果B状态持续时间达到300ms时，即可判断该按键的被触发状态为长按或连续按。
连续按为在长按该按键时，可以连续地多次触发该按键对应的按键功能，例如音量增加 或音量减少键，即可以通过长按不断触发该按键增加或减少设备的音量。
如果该按键不满足长按条件时，继续判断该按键是否为单击或双击的被触发状态。其中，单击或双击需要在按键抬起后进行检测，当任一个按键触发后产生有效的变化状态之后，按键抬起，如果在50ms内再次按下即判断为双击，如果50ms内按键为被再次按下即判断为单击。具体为，该按键对应的引脚的电平变化状态为，由A变化到B后，再由B变化到A，此时判断由B变化到A时间隔是时间是否小于或等于50ms，如果满足，则判断该按键的被触发状态为双击，如果不满足则判断该按键的被触发状态为单击。
当通过按键的引脚的电平的状态变化检测确定该按键的被触发状态后，将检测结果通知处理组件调用所述按键执行程序，基于按键执行程序查找该按键的被触发状态对应的功能函数，并通过处理组件调用并执行相应的功能函数，以确定按键对应的功能。并在执行该按键功能函数后初始化该按键执行程序，等待该按键再次被触发后检测该按键的被触发状态。
本实施例的方法可以适用于电子设备中的按键功能的实现，其中所述电子设备可以是设置有物理按键的运动手表或音箱。
可选地，在一个实际应用中，所述电子设备中设置了存储有图1实施例所述按键执行程序，所述电子设备中的每一个按键通过I/O线与处理组件的引脚一一对应连接，当任一按键被触发后，会引起处理组件相应引脚的电平的变化。通过设定的20ms定时实时检测任一个按键对应的引脚的电平的当前变化状态。当该设备的任一按键被按下时，基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态。并通过处理组件调用所述按键执行程序查找所述当前被触发状态对应的按键功能函数，并执行所述按键功能函数，从而实现该按键对应的相应按键功能。
例如，该设备中的某一按键的单击为静音功能，当检测到该按键被触发并引起该按键对应引脚的电平的变化后，根据该引脚的电平的变化状态确定该按键的被触发状态为单击，然后基于按键执行程序查找到该按键单击状态对应的功能函数为静音功能函数，此时处理组件执行静音功能函数，从而实现该电子设备中该按键的静音功能。
本实施例中，通过检测按键对应引脚的电平的变化状态的是否为有效变化状态，可以去除按键误触发或外界干扰引起的按键的“抖动”，大大提高了按键的被触发状态的检测准确率。且通过定时轮询检测按键对应引脚的变化状态，可以准确地检测出按键的被触发状态，并通过处理组件调用按键执行程序，查找并执行该按键被触发状态对应的功能函数从而实现该按键对应的按键功能，从而大大提高了按键检测的有效率和准确率。
可选地，在生产制造电子设备时，还可以基于图1实施例所述的按键配置方法用于对电子设备的按键功能的检测。
可选地，还可以包括，一种按键件检测装置，所述电子设备的按键与控制组件的引脚一一对应连接。

本发明中，可以通过20ms的定时，轮询检测每一个按键对应引脚的电平变化状态。
第四确定模块，用于基于所述任一个按键的不同被触发状态与不同变化状态的对应关系，确定所述当前变化状态对应的当前被触发状态。
因此基于任一个按键对应引脚的电平的变化状态，即可确定所述任一个按键的被触发状态。其中，所述按键的被触发状态根据用户的触发情况可以包括：单击、双击、长按或连续按。
第二查找模块，用于基于按键执行程序查找所述当前被触发状态对应的按键功能函数。
第二执行模块，用于执行所述按键功能函数。
第三检测模块，用于根据所述按键功能函数的执行结果，检测所述任一按键的被触发状态对应的按键功能是否正确。
在一个实际应用中，在基于图1实施例构建了按键执行程序之后，为了检测硬件电路与按键执行程序是否匹配有误，需要进行按键功能的检测。通过触发每一个按键的不同的被触发状态检测控制组件响应每一个按键的被触发状态后执行功能函数的执行结果是否与每一个按键不同被触发状态设定的功能相同。如果相同则所述任一按键的被触发状态对应的按键功能正确，如果不同，则可以基于图1实施例中所述的方法，对按键执行程序进行修改，从而完成按键功能的检测。
本实施例中，通过根据所述按键功能函数的执行结果，可以有效地检测每一个按键的不同被触发状态对应的按键功能是否正确，并实现根据按键检测结果修改相应的按键执行程序，大大提高了电子设备中按键功能的检测效率。
