在本实施例中，S103将各数字进行运算，获取与行数据的传输幅值对应的数值信息，并将数值信息反馈至S104。其中，数值信息是指当前行数据信号的整体传输幅值的数字化信息，由各数字进行运算获得。运算的方法包括但不限于平均值法、加权法以及两者的结合，方法的选择具体根据数据传输状况进行设定。其中，S103具体可以是可以实时地传送数值信息，做到实时准确地校准，以提高延迟的准确性。或者也可以选择在非数据传输期间，即水平方向或垂直方向上的空闲时间进行反馈，以避免对数据传送的影响。
在步骤S104中，根据数值信息对应调整输出数据信号传输幅值。
在本实施例中，S104接收数值信息，并根据数值信息对应调整数据传输发送端输出数据信号传输幅值，使之满足传输要求，让数据传输的接收端能够可靠地采集数据；同时自动化调整无需过多的人工参与调试，省时省力。
其中，根据数值信息对应调整传输幅值是指将数值信息调整至与预设数值信息相同，以使输出传输幅值与预设数值信息对应的幅值相同。其中，预设数值信息的设定根据实际数据传输状况进行设定，即，不同的数据传输状态对应有不同的预设数值信息。不同的数据传输状态对应不同的幅值范围，该幅值范围可以包括多个阈值，例如第一阈值(最低阈值)、第二阈值(中等阈值)以及第三阈值(最高阈值)等。在其中一个实施例中，预设数值信息对应数据信号传输幅值的第一阈值(最低阈值)，即根据数值信息对应调整数据传输发送端输出数据信号传输幅值，可以使幅值满足数据信号传输幅值的最低阈值。例如， 参见图2，图2为数据传输幅值调整的效果图(图中曲线a代表幅值基准位，曲线b数据传输线)，其中，A1为自动调整前的传输幅值，A2为自动调整前的传输幅值，数据信号传输幅值由A1增加到A2，满足传输的要求。
本实施例提供的信号调整方法，通过在时钟的信号沿识别各数据信号的传输幅值，并将各传输幅值转换为相应的数字，将各数字进行运算，获取传输幅值的数值信息，从而能够根据数值信息对应调整输出数据信号传输幅值，以使传输幅值满足传输要求，让数据传输的接收端能够可靠地采集数据，提高数据传输质量；且根据数据传输的不同状况有着不同的幅值搭配，以实现自适应的动态匹配，满足各种数据传输状况下的眼图要求，同时自动调整无需过多的人工参与调试，省时省力。
参见图3，图3为另一实施例中信号调整方法的流程图。
在本实施例中，该信号调整方法包括步骤S201、S202、S203、S204、S205以及S206。详述如下：
在步骤S201中，接入时钟信号和当前行数据信号，并在时钟的信号沿识别各数据信号的传输幅值。
在步骤S202中，将各传输幅值转换为相应的数字。

在本实施例中，通过S203存储各传输幅值及其对应的数字可以防止数据的丢失；另一方面，通过存储，可以积累更多的数字，以使S204对更多的数字进行运算，使得运算结果更加精准，同时效率更高。
在本实施例中，S205具体可以为建立通信连接，实时传输数值信息；或者可以为建立通信连接，在当前行数据信号停止传输时，传输数值信息。具体地,在当前行数据停止传 输时，传输的数值信息包括根据当前数据信号获取的数值信息，还可以包括存储累积的其他行数据信号对应的数值信息。其中，可以通过双向通信协议建立通信连接，双向通信协议包括但不限于I2C协议。当应用通信协议时，由于通信协议的线路和传输数据是分开的，不会互相影响，因此可以在数据传输的同时实时地传送数值信息，做到实时准确地校准。
本实施例提供的信号调整方法，通过在时钟的信号沿识别各数据信号的传输幅值，将各传输幅值转换为相应的数字，存储各数字，并将各数字进行运算，获取传输幅值的数值信息，从而能够根据数值信息对应调整输出数据信号传输幅值，以使传输幅值满足传输要求，让数据传输的接收端能够可靠地采集数据，提高数据传输质量；且根据数据传输的不同状况有着不同的幅值搭配，以实现自适应的动态匹配，满足各种数据传输状况下的眼图要求，同时自动调整无需过多的人工参与调试，省时省力。
