Description

一种触摸芯片校准方法、电子设备和存储介质 技术领域
本发明涉及触控技术，尤其涉及触摸芯片校准方法、电子设备和存储介质。
 背景技术
带触控功能的产品在装配后可能出现触摸不灵敏的情况，导致该问题的原因之一是产品在装配过程中的差异化，当差异达到一定程度时触摸芯片检测外部输入就会变得迟钝，从而导致触摸不灵敏。
因此，一般产品会以安装完成后的样品进行调试，调到一个适合的值后保存该配置参数，后续所有触摸芯片都使用同样的配置。该方法有一个明显的缺点：产品在批量生产时，由于物料公差以及工人在装配时存在一定的误差，导致部分产品在装配完成后触摸效果不好。
另外，部分触摸芯片增加了自适应的功能，但持续的自适应反而会使得产品在一些特定情况下出现触摸不灵敏甚至失效。例如：
1）部分触摸芯片处理能力不够，在自适应的过程中，触摸芯片本身在根据当前环境对输出阈值进行调整，此时无法处理当下输入的触摸信号，从而产生触摸不灵敏或者无反应；
2）正常的触摸状态有可能会被误适应，如手指长时间按压触摸PAD会被判断成新的环境，阈值在自适应的过程中被调整；当手指拿开后反而会产生触摸无反应的问题，这时就需要等待触摸芯片的下一次自适应后才能使用。
 技术问题

作为优选的实施方式，通信接口301为I 2C接口、SPI接口、UART接口或自定义接口。控制器320和触摸芯片310之间可以通过I 2C、SPI、UART或者是其他自定义接口协议进行通信。
作为优选的实施方式，在另一实施例中，预设条件被满足具体包括：获取到满足校准条件的触摸信号。
例如，触摸信号为长按某触摸按键10秒钟，或双击某触摸按键，则该触摸信号满足校准条件。即满足校准条件的触摸信号，具体包括：触摸按键被按下预设时长，或者触摸按键被双击。
作为优选的实施方式，触摸芯片310检测到满足条件的触摸信号后，由触摸芯片310调整配置参数。
作为优选的实施例，控制器320检测到满足校准条件的触摸信号之后，向触摸芯片310发送校准命令，然后由触摸芯片310调整配置参数。由于是操作者主动要求进行校准，因此可以不对触摸芯片310下电，避免影响操作者使用。
作为优选的实施方式，触摸芯片310进行触摸校准，可以采用自适应的方式，例如将未被触摸时各个位置的当前的电容值作为其基准电容值。本发明实施例不涉及对自适应算法本身的改进，在此不做赘述。

本发明实施例提供的电子设备，通过预设的触摸芯片自适应的条件，仅在预设条件被触发时进行触摸芯片的自适应，避免了部分触摸芯片处理能力不够，在自适应的过程中，触摸芯片无法处理当下输入的触摸信号，从而产生触摸不灵敏或者无反应的情形；以及避免了正常的触摸状态有可能会被误适应的情形。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
