在一个实施例中，该方法还包括：向从器件发送复位指令，复位指令用于指示从器件进行复位操作。
本申请的实施例中提供的复位方法，主器件接收到从器件发送预警信息时，对主器件进行复位操作，然后主器件向从器件发送复位指令，指示从器件进行复位操作，也即是说，在本申请的实施例中，当主器件接收到从器件发送的预警信息时，对主器件自身进行复位操作之后，主器件还会向从器件发送复位指令，以使从器件基于该复位指令进行复位操作，避免了主器件和从器件同时出现异常的情况下，仅对主器件进行复位操作不能解决电子设备中器件挂死的问题，进而进一步地提高了解决电子设备中器件挂死问题的可靠性。
在一个实施例中，上述复位指令包括第一复位指令或者第二复位指令，第一复位指令用于指示通过触发从器件的复位键进行器件复位，第二复位指令用于指示通过串行外设接口SPI接口对从器件进行器件复位。
第二方面，提供了一种复位方法，该方法应用于电子设备中的从器件中，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，电子设备包括主器件和从器件，该方法包括：

本申请的实施例中提供的复位方法，从器件向主器件发送第一信号，其中，第一信号用于请求与主器件之间进行数据交互，然后从器件检测是否接收到主器件发送的时钟信号；若未检测到主器件发送的时钟信号，向主器件发送预警信息。这样相当于预警信息是在从器件已经向主器件请求进行数据交互的基础上未检测到的时钟信号时发送的，使得预警信息指示主器件处于异常状态的准确性更高，进而提高了主器件基于预警信息进行复位操作的准确性，更加有效地解决电子设备中器件挂死的问题。
在一个实施例中，上述检测到主器件处于异常状态，包括：向主器件发送第一信号，第一信号用于请求与主器件之间进行数据交互；检测是否接收到主器件发送的时钟信号；若未检测到主器件发送的时钟信号，则确定主器件处于异常状态。
应理解，第一信号可以指示中断(interrupt，INT)信号。

为了便于理解，示例的给出部分与本申请实施例相关概念的说明以供参考。
串行外设接口(Serial Peripheral Interface，SPI)
SPI是指一种同步串行接口技术，是一种高速，全双工的同步通信总线。SPI通常 是以主从方式工作，应用在一个主器件和一个或多个从器件组成的系统中。一般SPI需要4根线进行数据传输，这4根线包括：
1，片选信号线(Slave Select/Chip Select，SS/CS)，用于选择需要进行通信的从器件。IIC主器件是通过发送从器件地址来选择需要进行通信的从器件的，而SPI主器件不需要发送从器件地址，直接将相应的从器件片选信号拉低即可。
2，串行时钟(Serial Clock，SCK)，和IIC的SCL一样，为SPI通信提供时钟。其中，SCK也可以被简称为时钟(Clock，CLK)。
3，主出从入信号线(Master Out Slave In/Serial Data Output，MOSI/SDO)，这根数据线只能用于主器件向从器件发送数据，也就是主器件输出，从器件输入。
4，主入从出信号线(Master In Slave Out/Serial Data Input，MISO/SDI)这根数据线只能用于从器件向主器件发送数据，也就是主器件输入，从器件输出。
示例性的，如图1中的(a)所示，主器件和从器件之间通过CS、CLK、MOSI、MISO四根数据线连接，同时主器件和从器件之间还存在中断信号(intterupt，INT)。主器件将SS拉低之后，会像从器件发送时钟信号。示例性的，主器件向从器件发送的时钟信号如图1中的(b)所示的CLK信号，包括两个时隙。主器件在第一个时隙通过MOSI向从器件传输数据，在第二个时隙通过MISO接收从器件发送的数据。在主器件和从器件之间进行数据传输的过程中，SS信号为低电平。
在现阶段，电子设备中通常采用SPI实现主器件和从器件之间的数据交互。通常，从器件在需要与主器件之间进行数据交互时，向主器件发送中断(interrupt，INT)信号(相当于第一信号)，主器件响应于INT信号，将该从器件对应的CS信号拉低，同时向从器件发送SCK信号(时钟信号)。从器件基于接收到的时钟信号，与主器件进行信号同步，并通过MISO或者MOSI与主器件之间进行数据交互。通常，从器件的尺寸较小，受到电子设备内的电磁干扰信号的影响较大，因此，在主器件和从器件之间出现数据交互异常的情况下，通常主器件会向从器件发送复位指令，以使从器件进行复位，恢复主器件和从器件之间的数据交互。然后随着芯片技术的进步，主器件的尺寸也越来越小。同时，电子设备中设置的电子器件越来越多，电子设备中的电磁干扰越来越严重，主器件也存在被电磁干扰信号干扰，导致主器件挂死的情况，进而导致主器件和从器件之间的数据交互异常。通常传统的方法，对从器件进行复位，不能完全解决现阶段电子设备中出现的主器件和从器件之间的数据交互异常的问题。
示例性的，在主器件与从器件之间正常通讯的情况下，如图2中的(a)所示，在从器件的INT信号为低电平时，从器件的状态为空闲状态，主器件可以与从器件之间进行数据交互。每间隔预设的时长，主器件在CS上发送一个脉冲信号，同时，随着CS上的脉冲，发送一个时钟信号。
在主器件收到电磁干扰信号的干扰，出现挂死现象的情况下，如图2中的(b)所示，从器件的INT信号为低电平时，从器件的状态为空闲状态，主器件可以与从器件之间进行数据交互。每间隔预设的时长，主器件在CS上发送一个脉冲信号，但是，由于主器件被电磁信号干扰，从器件只能接收到CS上的脉冲信号，不能收到主器件发送的时钟信号。由于从器件无法收到主器件发送的时钟信号，主器件和从器件之间无法基于时钟信号恢复通信同步，因此，主器件和从器件之间无法恢复数据交互。
应理解，在主器件收到电磁干扰信号的干扰，出现挂死现象的情况下，还可以是CS信号、CLK信号、MOSI信号出现异常情况，本申请实施例对此不做限制。
有鉴于此，本申请实施例提供了一种复位方法，应用在电子设备中的主器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，从器件向主器件发送预警信息，主器件接收到该预警信息时，对主器件进行复位操作，其中，预警信息用于指示主器件处于异常状态，这样使得在芯片尺寸越来越小的趋势中，主器件受到电子设备中电磁干扰信号的影响处于异常状态的情况下，可以通过对主器件的复位操作解决主器件的挂死问题，与传统方法仅能解决从器件的挂死问题相比，本申请实施例提供的复位方法，能够在电子设备中电子器件数量增多，或者电子器件的尺寸减小的情况下，解决主器件的挂死问题，进而能够有效地恢复电子器件之间的数据交互。

应理解，上述应用场景的描述只是一种示例，并不构成对本申请实施例所应用的场景的限制。
下面结合图8至图14对本申请实施例提供的复位方法进行详细描述。
图8为本申请实施例提供的一种复位方法的流程示意图，如图8所示，该方法应用在电子设备中，电子设备包括主器件和从器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，该方法包括：
S101、从器件向主器件发送预警信息，预警信息用于指示主器件处于异常状态。
应理解，在一些电子设备中，主器件通常是处理能力较强的电子器件，从器件是处理能力较弱的电子器件。主器件和从器件之间可以通过SPI总线的数据交互，其中，从器件可以基于主器件发送的控制信号来进行数据交互。示例性的，主器件向从器件发送时钟信号，以使从器件基于该时钟信号与主器件进行同步，进而使得主器件与从器件之间进行数据交互。
随着芯片技术的不断进步，主器件的尺寸也越来越小，同时电子设备中设置的电子器件越来越多，电子设备中的电磁干扰越来越严重，主器件也存在被电磁干扰信号干扰导致器件挂死的情况。
可选地，主器件处于异常状态包括：在片选CS信号为第一电平且未向从器件发送时钟信号的状态。
示例性的，在主器件被电磁干扰信号干扰导致器件挂死的情况下，如图9中的(a)所示，主器件已经将从器件对应的CS信号设置为预设的电平(例如第一电平)，但是无法向从器件发送CLK信号，这样使得从器件无法获得时钟信号与主器件进行通信同步，进而使得主器件和从器件之间不能进行数据交互。在从器件检测到CS信号为第一电平，但是未接收到CLK信号的情况下，从器件判断主器件出现异常，从器件向主器件发送预警信息，该预警信息用于指示主器件处于异常状态。
应理解，在一些可能的情况下，主器件与多个从器件连接，每个从器件有其对应的片选信号线。主器件将其中的一个或多个片选信号线上的电平设置为第一电平时，则说明主器件与该片选信号线对应的从器件之间进行数据交互。应理解，根据不同的 设置，第一电平可以是指高电平，也可以是指低电平，本申请实施例对此不作限制。
可选地，主器件处于异常状态包括：在片选CS信号为第一电平时，主器件和从器件之间未进行数据交互。
示例性的，在主器件被电磁干扰信号干扰导致器件挂死的情况下，如图9中的(b)所示，主器件已经将从器件对应的CS信号设置为预设的电平(例如第一电平)，但是在MOSI和/或MISO上没有数据传输。在从器件检测到CS信号为第一电平时，但是没有检测到MOSI和MISO上的数据传输，则从器件判断主器件出现异常，从器件向主器件发送预警信息，该预警信息用于指示主器件处于异常状态。
可选地，主器件处于异常状态包括：片选CS信号转换到第一电平所用时长小于预设时长阈值。
示例性的，在主器件被电磁干扰信号干扰导致器件挂死的情况下，如图9中的(c)所示，从器件检测到主器件将CS信号设置为预设电平(第一电平)所用的时长Δt小于预设时长阈值，则从器件判断主器件处于异常状态，从器件向主器件发送预警信息，该预警信息用于指示主器件处于异常状态。
S102、主器件接收到预警信息时，基于预警信息进行复位操作。
其中，复位操作是指对器件进行操作，去除掉器件中运行错误的进程对器件工作的影响。通常可以通过对器件进行下电重启，或者通过清除器件中的进程来对器件进行复位操作。其中，通过对器件进行下电重启的复位操作可以被称为硬复位操作。通过清除器件中的进程来对器件进行复位操作可以被称为软复位操作。主器件接收到从器件发送的预警信息时，主器件可以进行下电重启，完成对主器件的复位操作。也可以通过清除相关的进程完成对主器件的复位操作。
本申请的实施例中提供的复位方法，应用在电子设备中的主器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，从器件向主器件发送预警信息，主器件接收到该预警信息时，对主器件进行复位操作，其中，预警信息用于指示主器件处于异常状态，这样使得在芯片尺寸越来越小的趋势中，主器件受到电子设备中电磁干扰信号的影响处于异常状态的情况下，可以通过对主器件的复位操作解决主器件的挂死问题，与传统方法仅能解决从器件的挂死问题相比，本申请实施例提供的复位方法，能够在电子设备中电子器件数量增多，或者电子器件的尺寸减小的情况下，解决主器件的挂死问题，进而能够有效地恢复电子器件之间的数据交互。
在一些可能的情况下，从器件向主器件发送预警信息之前，可以先检测主器件是否处于异常状态，并在主器件处于异常状态时，向主器件发送预警信息。下面通过图9所示实施例来详细描述。
图10为本申请实施例提供的另一种复位方法的流程示意图，该方法应用在电子设备中，电子设备包括主器件和从器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，该方法包括：
S201、从器件向主器件发送第一信号，其中，第一信号用于请求与主器件之间进行数据交互。
其中，当从器件需要与主器件之间进行数据交互时，会向主器件发送中断(interrupt， INT)信号(相当于第一信号)。主器件在接收到中断信号时，主器件确定该从器件可以进行数据交互。这时，主器件会将从器件对应的片选信号线的电平设置为第一电平，并向从器件发送时钟信号。
S202、从器件检测是否接收到主器件发送的时钟信号；若未检测到主器件发送的时钟信号，则执行S203。
其中，从器件在检测到片选信号线上的电平为第一电平时，若检测到主器件发送的时钟信号，则可以基于该时钟信号与主器件进行同步，并在同步之后，与主器件之间进行数据交互；若未检测到主器件发送的时钟信号，则确定主器件处于异常状态。
S203、从器件向主器件发送预警信息。
其中，预警信息是从器件在片选CS信号为第一电平且未接收到主器件发送时钟信号时发送的。
本申请的实施例中提供的复位方法，从器件向主器件发送第一信号，其中，第一信号用于请求与主器件之间进行数据交互，然后从器件检测是否接收到主器件发送的时钟信号；若未检测到主器件发送的时钟信号，向主器件发送预警信息。这样相当于预警信息是在从器件已经向主器件请求进行数据交互的基础上未检测到的时钟信号时发送的，使得预警信息指示主器件处于异常状态的准确性更高，进而提高了主器件基于预警信息进行复位操作的准确性，更加有效地解决电子设备中器件挂死的问题。
S204、主器件在接收到预警信息时，基于预警信息进行复位操作。
S205、主器件向从器件发送复位指令，复位指令用于指示从器件进行复位操作。
其中，复位操作是指对电子器件进行相关的操作，去除掉器件中运行错误的进程对器件工作的影响。复位操作通常可以通过对器件进行下电重启，或者通过清除器件中的进程来对器件进行复位操作。其中，通过对器件进行下电重启的复位操作可以被称为硬复位操作。通过清除器件中的进程来对器件进行复位操作可以被称为软复位操作。
可选地，复位指令包括第一复位指令和第二复位指令，第一复位指令包括通过触发从器件的复位键进行器件复位。
应理解，通过触发从器件的复位键进行器件复位是指对从器件进行下电重启的复位操作，也即是说，第一复位指令可以是通过硬复位操作进行的复位指令。
可选地，第二复位指令包括通过SPI接口对从器件进行器件复位。
应理解，通过SPI接口对从器件进行器件复位通常是指通过SPI接口清除从器件中的进程进行的复位操作，也即是说，第二复位指令可以是指通过软复位操作进行的复位指令。
S206、从器件基于复位指令进行复位操作。
本申请的实施例中提供的复位方法，主器件接收到从器件发送预警信息时，对主器件进行复位操作，然后主器件向从器件发送复位指令，指示从器件进行复位操作，也即是说，在本申请的实施例中，当主器件接收到从器件发送的预警信息时，对主器件自身进行复位操作之后，主器件还会向从器件发送复位指令，以使从器件基于该复位指令进行复位操作，避免了主器件和从器件同时出现异常的情况下，仅对主器件进行复位操作不能解决电子设备中器件挂死的问题，进而进一步地提高了解决电子设备 中器件挂死问题的可靠性。
在一种可能的情况下，从器件还可以在检测到CS信号为第一电平时继续检测主器件和从器件之间是否进行数据交互确定主器件是否处于异常状态。下面通过图11所示实施例来详细描述。
图11为本申请另一个实施例中提供的复位方法的流程示意图，该方法应用在电子设备中，电子设备包括主器件和从器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，如图11所示，该方法包括：
S301、从器件检测到片选CS信号为第一电平时，检测到主器件和从器件之间的MOSI和MISO上是否有数据传输。若否，则执行S302。
应理解，当CS信号为第一电平时，主器件和从器件之间进行数据交互，此时，若从器件检测到MOSI和MISO上均没有数据传输，则说明主器件和从器件之间没有数据交互，相当于在MOSI和/或MISO上信号异常。这种异常情况通过是主器件受到电磁干扰信号的干扰形成的。从器件基于此确定主器件处于异常状态。
S302、从器件向主器件发送预警信息。
S303、主器件在接收到预警信息时，基于预警信息进行复位操作。
S304、主器件向从器件发送复位指令，复位指令用于指示从器件进行复位操作。
S305、从器件基于复位指令进行复位操作。
在一种可能的情况下，从器件还可以检测CS信号转换为第一电平时所用的时长的来确定主器件是否处于异常状态。下面通过图12所示实施例来详细说明。
图12为本申请另一个实施例中提供的复位方法的流程示意图，该方法应用在电子设备中，电子设备包括主器件和从器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，如图12所示，该方法包括：
S401、从器件检测到片选CS信号转换为第一电平所用的时长是否小于预设时长阈值，若是，则执行S402。
以第一电平为低电平为例进行说明。
应理解，主器件正常工作时，当主器件与从器件之间需要进行数据交互，则主器件将CS信号下拉到第一电平。CS信号的电平转换为第一电平时所占用的时间，也即是该信号的下降沿的时长通常为预设时长。在主器件收到电磁干扰信号的干扰出现异常时，该信号的下降沿的时长通常较短，因此，在CS信号的下降沿的时长小于预设时长阈值时，从器件确定主器件处于异常状态。
S402、从器件向主器件发送预警信息。
S403、主器件在接收到预警信息时，基于预警信息进行复位操作。
S404、主器件向从器件发送复位指令，复位指令用于指示从器件进行复位操作。
S405、从器件基于复位指令进行复位操作。
在一种可能的情况下，还可以通过增加一个主器件检测模块来确定主器件的问题。示例性的，如图13所示，主器件检测模块可以包括CS检测子模块、CLK检测子模块、MOSI检测子模块和MISO检测子模块。其中，CS检测子模块与CS信号线连接，用于检测CS信号；CLK检测子模块与CLK信号线连接，用于检测CLK信号；MOSI检测子模块与MOSI信号线连接，用于检测MOSI信号；MISO检测子模块与MISO 信号线连接，用于检测MISO信号。
示例性的，当主器件检测模块检测到CS信号的电平被拉低(设置为低电平)，但是CLK信号线上没有时钟信号的情况下，则说明主器件可能出现挂死，因此可以向主器件发送预警信息，以使主器件基于该预警信息对主器件进行复位。
应理解，主器件检测模块可以集成在主器件中，也可以是设置在主器件之外的电路模块，本申请实施例对此不作限制。
在一种可能的情况下，由于一些从器件的处理能力较弱，因此，从器件不具备检测时钟信号的功能，在这种情况下，主器件可以直接对主器件进行复位操作，无需在接收到从器件发送的预警信息时再对主器件进行复位操作。下面通过图14所示的实施例来详细说明。
图14为本申请另一个实施例提供的复位方法的流程示意图，该方法应用在电子设备中，电子设备包括主器件和从器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，该方法包括：
S501、主器件检测到数据线上的信号异常时，对主器件进行复位操作。
应理解，数据线可以包括图1中所示的CS信号线、CLK信号线、MOSI信号线和MISO信号线。主器件检测到任一路信号线上出现异常时，则对主器件进行复位操作。
应理解，任一数据线上出现的信号异常，可以是主器件处于异常状态导致的，也可以是从器件处于异常状态导致的。这样相当于只要主器件和从器件之间的数据交互存在异常，主器件均对主器件自身进行复位操作。也即是说，无需从器件去检测主器件是否处于异常状态。
S502、主器件向从器件发送复位指令。
S503、从器件基于复位指令进行复位操作。
本申请的实施例中提供的复位方法，应用在电子设备中，电子设备包括主器件和从器件，主器件用于向从器件发送时钟信号，主器件与从器件之间基于时钟信号进行数据交互，该方法包括：主器件检测到数据线上的信号异常时，对主器件进行复位操作，然后主器件向从器件发送复位指令，从器件基于复位指令进行复位操作。通过本申请实施例提供的复位方法，无需从器件去检测主器件是否处于异常状态，使得在从器件的处理能力较弱导致的从器件无法检测主器件是否处于异常状态的情况下，能够通过主器件主动对自身进行复位操作，解决主器件的器件挂死的问题，进而能够有效地恢复电子器件之间的数据交互。
应该理解的是，虽然上述实施例中的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，流程图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。

在一个实施例中，复位指令包括第一复位指令或者第二复位指令，第一复位指令用于指示通过触发从器件的复位键进行器件复位，第二复位指令用于指示通过串行外设接口SPI接口对从器件进行器件复位。
本实施例提供的主器件，用于执行上述实施例的复位方法，技术原理和技术效果相似，此处不再赘述。

因此，在本申请的实施例中描述的各示例的单元，能够以电子硬件、或者计算机软件和电子硬件的结合来实现。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
