【经验】电容式多通道触摸传感器CPT112S的开发环境搭建
电容式多通道触摸传感器CPT112S是SILICON LABS公司推出的一款 12通道电容式触摸控制器。采用 QSOP24 封装,其设有一个可重新配置的 I2C 接口。 开发时采用官方提供的Touch Xpress控件进行开发,简单方便。
工欲善其事,必先利其器。虽然官方提供的Touch Xpress控件操作非常简便,但是对于新手来说还是需要简单的指导操作,如下即是环境搭建的详细步骤:
1、打开Simplicity Studio,安装Touch Xpress控件,有如下两种方式。
2、如下图可以直接下一步。
3、如下图采用默认的选择即可。
4、在安装过程中有可能会出现如下错误,跟网络情况有关,请多尝试安装几次。
5、如果一切顺利,就可以进入开发环境了,如下可以新建一个工程。
6、在修改好各个参数后,点击1处的[program to device]即可生成2处的.hex文件,如果硬件也成功连则可直接烧录。

取代电容触摸按钮!Silicon Labs新一代电容感应解决方案
Silicon Labs强势推出新一代应用于电容触摸的CPT电容触摸系列,该系列产品被设计用来快速取代机械按钮与现代电容式触摸按钮,极大地消除了开发固件的复杂性并极大地减少开发时间。
【经验】12 通道电容式触摸控制器CPT112S评估板操作使用说明
CPT112S是Silicon Labs公司推出的一款 12 通道电容式触摸控制器。采用 QSOP24 封装,其设有一个可重新配置的 I2C 接口。 CPT112S TouchXpress 评估板设有 12 个电容式感应垫、一个可选的 4 通道滑动条以及一个用于触控反馈的蜂鸣器。该板可通过扩展头或拆分引脚连接至主处理器,并使用 USB 连接器连接至 PC。本文基于该连接方法,对其操作进行说明。
使用触摸芯片CPT112S demo进行触摸测试时,发现灵敏度非常高,手还没接触到触摸按键就已经触发了按键,是什么原因?怎么处理?
由于原厂demo默认设置的active值比较低,而且demo的触摸信噪比非常高,当手接近触摸按键的时候会引起触摸值的明显变化,如果active值过低,则会触发按键时间。所以需要使用capactive sense profiler工具对demo的测试,根据触摸值曲线来对触摸delta值、active以及inactive值进行调整,并将active值设置到可靠触摸下的触摸值增量,这样就可以降低误触的概率,如有必要可以增加去抖次数来防止误触事件。
