Description

触摸响应方法、芯片及智能设备 技术领域
本申请涉及电子设备技术领域，尤其涉及触摸响应方法、芯片及智能设备。
背景技术
随着智能设备的不断发展，越来越多的智能设备开始采用模块化设计。以智能平板为例，智能平板通常可以基于多种不同规格的模块化接口，模拟出多个不同的外接通道，与不同类型的外部设备进行互联。
例如，采用模块化设计的智能平板，基于模块化接口模拟出的外部通道，通常可以包括PC通道、HDMI外置通道、VGA外置通道等等。其中，在智能平板领域，智能平板通常使用Android***作为主***，而在实际应用中，通过模块化接口与智能平板保持互联的外接设备所支持的操作***，可能会与主***不同；比如，与智能设备互联的外界设备可能是支持Windows***的PC设备。因此，对于智能平板的外接通道而言，通常可以被划分为主***外接通道和非主***外接通道。所谓主***外接通道，是指与该外接通道对接的外接设备所支持的操作***与主***相同；而所谓非主***外接通道，是指与该外接通道对接的外接设备所支持的操作***与主***不同。
在实际应用中，当智能平板需要显示通过非主***外接通道接收到的显示内容，主Android***通常会启动一个窗口(例如tvsetting窗口)，然后将需要显示的内容在此窗口内进行显示，从而使得智能平板可以作为一个统一的平台，融合对接的不同类型的外接设备的功能，对各种类型的外接设备进行集中管理；例如，融合电视技术、电脑技术等等。在这种情况下，势必要求智能平板能够支持多***同时运行，例如主***Android和PC模块的windows***同时运行。然而，由于多个同时运行的***，通常都需要用到触摸数据，因此在相关技术中，则要求主***对触摸屏传输的触摸数据进行多路传输，分别提交给不同的操作***进行触摸响应。
相关技术中，如图1中所示，触摸屏10一般是通过USB口和UART口同时传输触摸数据。USB口输出的触摸数据，通过USB选择开关13经模拟出的N个通道14(N为自然数)传输到对应的外接设备15进行响应。而通过UART口输出的触摸数据，通过一块MCU11为 桥梁模拟出USB设备，并通过USB通信传输到芯片12搭载的操作***进行响应。由于UART口的数据可靠性较差，而且串口的传输带宽受限，在使用UART口传输触摸数据时，需要开发串口传输协议，因此当使用UART口传输的触摸数据较大时，容易导致触摸数据传输错误，还会影响传输速度。

这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
在现有技术中，参考图1，在使用智能设备的过程中，为了实现触摸数据的多路传输，通常会为触摸屏10搭载USB口和UART口，而触摸屏10可以将触摸数据同时分发到USB口和UART口，通过USB口和UART口来同时多路的传输触摸数据。如图1中所示，MCU11中也搭载了USB口和UART口，触摸屏10的USB口通过USB通信连接USB切换开关13，触摸屏10的UART口通过串口通信连接MCU11的UART口，MCU11的USB口通过USB通信连接芯片12中搭载的USB口，同时，USB切换开关13还通过GPIO连接MCU11。USB切换开关13通过模拟出的N(N为自然数)个通道14连接N(N为自然数)个外接设备15，其中，每个通道14连接一个外接设备15。
当触摸屏10监听到用户针对触摸屏10的触摸事件时，可以将相关的触摸数据(比如触摸坐标等触摸位置数据)，同时分发至USB口和UART口进行触摸响应。
一方面，触摸屏10可以通过USB口将触摸数据传输给MCU11，由MCU11通过GPIO控制USB切换开关13导通的通道14，进一步输出到与导通的通道14对应的外接设备15。
另一方面，可以为触摸屏10的UART口预先开发对应的串口通信协议；触摸屏10可以基于开发的串口通信协议，将触摸数据封装成串口数据传输到MCU11，经MCU11解析串口数据后，再转化为标准触摸格式，通过USB通信传输到芯片12搭载的操作***。即在这种情况下，UART口输出的触摸数据需要通过一块MCU为桥梁模拟出一台USB设备，才能 实现触摸数据的多路并发。
然而，由于UART口的数据可靠性较差，串口的传输带宽受限；而且，在使用UART口传输触摸数据时，需要单独开发串口传输协议，因此当使用UART口传输的触摸数据较大时，容易导致触摸数据传输错误，还会影响传输速度。
基于此，本申请实施例提出了一种智能设备40，请参见图2，图2为本申请一示例性实施例示出的一种改进后的智能设备40的硬件架构图。智能设备40包括触摸屏41、USB切换开关42以及芯片30，USB切换开关42连接至若干外接设备43。
芯片30包括第一USB口301和第二USB口302。触摸屏41上搭载有第四USB口411，第一USB口301通过USB通信与第四USB口411连接。第二USB口302通过USB通信与USB切换开关42连接，芯片30还通过GPIO与USB切换开关42连接。
本申请实施例中，智能设备40可以根据N(N为自然数)个外接设备43的连接端口模拟出N(N为自然数)个连接通道43。比如：PC通道、HDMI外置通道、VGA外置通道等等。图2中的第一通道43以及第N通道43即可以理解为上述连接通道的其中之一。芯片30通过GPIO控制USB切换开关42导通的通道43。
当触摸屏41监听到用户针对触摸屏41的触摸事件时，可以将相关的触摸数据(比如触摸坐标等触摸位置数据)发送至第一USB口301。一方面，将触摸数据提交至芯片30搭载的操作***进行触摸响应；另一方面，将触摸数据发送至第二USB口302，由第二USB口302通过USB切换开关42导通的通道43将触摸数据提交至与该导通的通道43对应的外接设备44进行触摸响应。
本申请实施例可应用于芯片30支持USB Device时，可以将芯片30中的第二USB口302配置为USB Device口，第二USB口302通过USB切换开关42经过模拟出的N个通道43连接对应的外接设备44，芯片30通过GPIO控制USB切换开关42导通的通道43，并通过USB切换开关42导通的通道43将触摸数据从第二USB口302提交至对应的外接设备44进行触摸响应。
其中，芯片30被配置为：
通过第一USB口301接收触摸屏41返回的触摸数据；将触摸数据提交至芯片30搭载的操作***进行触摸响应；以及，将触摸数据发送至第二USB口302，由第二USB口302通过USB切换开关42将触摸数据提交至对应的外接设备44进行触摸响应。
本申请实施例中，外接设备44搭载的操作***可以与智能设备40搭载的操作***不同。 而在其他实施例中，外接设备44搭载的操作***也可以与智能设备40搭载的操作***相同。
本申请实施例通过在智能设备40上搭载包含第一USB口301和第二USB口302的芯片30，当芯片30通过第一USB口301接收触摸屏41返回的触摸数据时，一方面，将触摸数据提交至芯片30搭载的操作***进行触摸响应；另一方面，可以将触摸数据发送至第二USB口302，由第二USB口通过USB切换开关将触摸数据提交至对应的外接设备进行触摸响应，从而实现触摸数据的多路传输。由于在触摸数据被响应的过程中，只需要使用USB口进行通信，不再需要使用UART口进行通信；因此，可以显著的利用USB口的传输速度快且兼容性好的特点，即可以提升智能设备在响应触摸数据时的响应速度以及可靠性，又可以提升智能设备的兼容性。
在图2所示实施例中，可应用于芯片30支持USB Device时，将芯片30中的第二USB口302配置为USB Device口，第二USB口302通过USB切换开关42连接若干外接设备44，并通过USB切换开关42的导通的通道43将触摸数据从第二USB口302提交至对应的外接设备44进行触摸响应。然而在其他实施例中，当芯片30不支持USB Device时，需要将触摸数据中转到其他支持USB Device的端口进行传输，基于此，提供了另外一种智能设备，如图3所示。
图3是本申请实施例根据一示例性实施例示出的另一种智能设备50的硬件架构图。本实施例中，智能设备50还包括MCU45，MCU45包括第三USB口451和第五USB口452。其中，第二USB口302通过USB通信与第五USB口452连接。第三USB口451通过USB通信与USB切换开关42连接，MCU45还通过GPIO与USB切换开关42连接。
本实施例中，第一USB口301和第二USB口302均被配置为USB host口，第三USB口451被配置为USB Device口，且第三USB口451的描述符被配置为标准触摸协议描述符。
当芯片30通过第一USB口301接收触摸屏41返回的触摸数据时，一方面，将触摸数据提交至芯片30搭载的操作***进行触摸响应；另一方面，可以将触摸数据发送至第二USB口302，然后通过MCU45将触摸数据中转到被配置为USB Device口的第三USB口451，第三USB口451可以通过USB切换开关42连接外接设备44，MCU45通过GPIO控制USB切换开关42导通的通道43，并通过USB切换开关42导通的通道43将触摸数据从第三USB口451提交至对应的外接设备44进行触摸响应。
其中，芯片30被配置为：通过第一USB口301接收触摸屏41返回的触摸数据；将触摸数据提交至芯片30搭载的操作***进行触摸响应；以及，将触摸数据发送至第二USB口302， 经MCU45将触摸数据由第二USB口302发送至第三USB口451；通过USB切换开关42将触摸数据提交至对应的外接设备44进行触摸响应。
本实施例中，应用于芯片30不支持USB Device时，通过MCU45将触摸数据中转到被配置为USB Device口的第三USB口451，第三USB口451可以通过USB切换开关42连接外接设备44，MCU45控制USB切换开关42导通的通道43，并通过USB切换开关42导通的通道43将触摸数据从第三USB口451提交至对应的外接设备44进行触摸响应。
图4为本申请实施例根据一示例性实施例示出的一种触摸响应方法，该触摸响应方法应用于智能设备，所述智能设备搭载了触摸屏、主芯片、USB切换开关以及与USB切换开关相连的若干外接设备；其中，主芯片包括第一USB口和第二USB口；第一USB口与触摸屏连接。
本申请实施例的触摸响应方法包括以下执行步骤：
在步骤41中，通过第一USB口接收触摸屏返回的触摸数据。
本申请实施例中，可以在触摸屏上搭载第一USB口。第一USB口可以默认被配置为USB host口，并与智能设备搭载的触摸屏保持连接。主芯片用于监听用户触摸操作，当监听到了用户的触摸操作，将数据传输给第一USB口。
在步骤42中，将触摸数据提交至主芯片搭载的操作***进行触摸响应。
在一可选的实施例中，主芯片搭载的操作***可以是Android***，在另一可选的实施例中，主芯片搭载的操作***也可以是其他***，如Linux***、Windows***等。操作***中配置有管理和控制智能设备的硬件与软件资源的计算机程序，通过驱动相应的程序对触摸数据进行响应。
在步骤43中，将触摸数据发送至第二USB口，由第二USB口通过USB切换开关将触摸数据提交至对应的外接设备进行触摸响应。
本实施例中，第二USB口可以配置成USB host口，也可以配置成USB Device口。
在一种情况下，当主芯片支持USB Device时，可以将主芯片中的第二USB口配置为USB Device口，且第二USB口的描述符被配置为标准触摸协议描述符。第二USB口可以通过USB切换开关连接外接设备，主芯片控制USB切换开关导通的通道，并通过USB切换开关导通的通道将触摸数据从第二USB口提交至对应的外接设备进行触摸响应。
在另一种情况下，当主芯片不支持USB Device时，可以将第二USB口配置为USB host 口。此时，需要在智能设备中搭载MCU。MCU包括第三USB口，其中，第三USB口被配置为USB Device口，且第三USB口的描述符被配置为标准触摸协议描述符。
通过MCU将触摸数据由第二USB口发送至第三USB口；由第三USB口通过USB切换开关将触摸数据提交至对应的外接设备进行触摸响应。也就是说，当主芯片不支持USB Device时，通过MCU将触摸数据中转到被配置为USB Device口的第三USB口，第三USB口可以通过USB切换开关连接外接设备，MCU控制USB切换开关导通的通道，并通过USB切换开关导通的通道将触摸数据从第三USB口提交至对应的外接设备进行触摸响应。
