图1为本申请实施例中接口管脚配置的方法的流程示意图，如图1所示，该接口管脚配置的方法可以包括如下步骤：
步骤101：第一设备通过接口的预设管脚读取外接设备或模块的预存信息；所述外接设备或模块通过所述接口与所述第一设备连接；所述预存信息包括：所述外接设备或模块的类型、供电方式或通信接口类型；

实施中，所述预存信息还可以包括：所述外接设备或模块的属性信息，所述属性信息包括：主设备，或者从设备；
所述方法，还可以包括：
根据所述属性信息确定所述第一设备与所述外接设备或模块的主从关系。
具体实施中，在状态检测或控制等进程中，还涉及第一设备与所述外接设备或模块的主从关系的确定，所以，所述预存信息还可以包括所述外接设备或模块的属性信息，即，所述外接设备或模块为主设备或从设备。
若属性信息为主设备，则确定第一设备与所述外接设备或模块的主从关系为：第一设备为从设备，所述外接设备或模块为主设备；若属性信息为从设备，则确定第一设备与所述外接设备或模块的主从关系为：第一设备为主设备，所述外接设备或模块为从设备。
实施中，所述接口还可以包括：状态检测子接口、控制子接口、对外供电子接口、或充电子接口。
图3为本申请实施例中的接口的布局结构示意图，如图3所示，所述接口中的对外供电子接口是第一设备对外接设备或模块提供电源的子接口；充电子接口是可提供电源的外接设备或模块为第一设备提供电源的子接口；插入检测子接口为判断外接设备或模块是否正确插接到所述接口的子接口；PCIE子接口、USB子接口、UART子接口和I2C子接口分别为高、中、低 速通信子接口；SIM卡子接口为与具备无线通讯功能的外接设备或模块中SIM卡进行通信的子接口；状态检测子接口、控制子接口为检测、控制外接设备或模块的功能状态的接口，可以按照功能需求自由定义接口管脚数量和分布方式。
图4为本申请实施例中的接口管脚分布示意图，如图4所示，由于PCIE子接口，USB子接口，I2C子接口和UART子接口是目前设备连接中常用的通信接口，因此将这些子接口相互独立的定义在接口的相关管脚上。
管脚1～6属于对外供电子接口，管脚7和62属于插入检测子接口，管脚11、13、17、19、23、25、29、31、33属于PCIE子接口，管脚37和39属于UART子接口，管脚47、49、51、53、55属于SIM卡子接口，管脚59、61、63属于I2C子接口，管脚65～68属于充电子接口，管脚44、46、50、52、56、58属于USB子接口，管脚8、10、12、14、16、18、20、22、24、26、28、30、32、34、38、40属于状态检测子接口和控制子接口复用管脚。
为了降低数据管脚之间，尤其是高速率通信的数据管脚之间的干扰，可以在数据管脚之间设置GND管脚，例如，管脚9、15、21、27、35、36、42、45、48、54、57、60均为降低数据管脚之间干扰的GND管脚。
实施中，所述状态检测子接口与所述控制子接口可以复用同一数据管脚。
具体实施中，由于状态检测与控制通常不是同时进行的，所以可以将状态检测子接口与控制子接口可以复用同一数据管脚，以合理利用接口的管脚。
基于同一申请构思，本申请实施例中还提供了一种接口管脚配置的装置，由于该装置解决问题的原理与一种接口管脚配置的方法相似，因此该装置的实施可以参见方法的实施，重复之处不再赘述。

本发明实施例中的接口管脚配置的方法和装置，可应用于设备间接口连接时的接口管脚配置。图6为本申请实施例中接口管脚配置的实施流程示意图，如图6所示，下面结合一个具体的应用场景进行描述。连接接口后，首先通过插入检测子接口进行插入检测，确定接口的所有管脚是否连接？若没有，则退出接口连接；若是，则接通接口的I2C子接口。通过I2C子接口的数据管脚读取外接设备或模块的预存信息后，判断外接设备或模块的类型是否是第一设备允许连接的类型？若不是，则退出接口连接；若是，则读取预存信息中的外接设备或模块的供电方式。根据供电方式确定外接设备或模块是否由第一设备供电？若是，则接通对外供电子接口对外接设备或模块进行供电；否则，接通充电子接口，由外接设备或模块对第一设备进行供电。配置完外供电子接口或充电子接口后，读取预存信息中的通信接口类型。根据预存信息中的通信接口类型接通所述接口中的一个或多个通信子接口，其中，通信子接口可以包括：PCIE子接口、UART子接口、SIM卡子接口、I2C 子接口或USB子接口等等。
由上述实施例可见，在本申请实施例提供的技术方案中，在对接口的管脚配置之前，通过接通接口的预设管脚(I2C子接口的数据管脚)读取外接设备或模块的预存信息，并根据所述预存信息对第一设备与所述外接设备或模块连接的接口进行配置，第一设备可以根据所述外接设备或模块的预存信息进行接口配置，避免现有技术中在接口插接好后直接为各引脚供电，可能导致的设备损坏等安全隐患，提高设备连接的安全性。
本领域内的技术人员应明白，本申请的实施例可提供为方法、系统、或计算机程序产品。因此，本申请可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本申请可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本申请是参照根据本申请实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上， 使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
