基于 Silicon Lab公司CPT007芯片设计的电容触摸按键板

技术问答

随着智能设备的普及，智能触摸也成了智能设备的标配，可以说触摸相较于传统的机械按键，除了寿命长，人体交互灵活外，更能彰显设备的科技感，那么如何在传统的设备上增加电容触摸按键呢，笔者将带你进入触摸按键的世界一探究竟。

笔者由于产品升级换代，需要将原有机械键盘，更换为电容触摸按键，由于是更换，主要要求是：

1：要兼容原来键盘的使用模式，即当按键按下的时候，IO口处于低电平触发。

2、由于是电容触摸按键，肯定有驱动IC，要防止IC由于静电等原因死机，所以要有复位引脚；

3、要支持7个按键；

4、由于原有设备没有蜂鸣，需要增加按键蜂鸣。

综合以上因素，经过世强的FAE推荐，最终选择了Silicon Lab公司的CPT007B 电容触摸芯片。

从CPT007B的技术手册开头的概述看，这颗芯片的设计理念也正式让用户以最小的开发量实现电容触摸按键替代机械按键。在芯片的设计过程中，设计者还增加了对湿气的抗干扰能力以及接近唤醒等先进功能。

Silicon Lab公司针对这个芯片给出了原理图和demo板，不得不说demo板（见图1）还是比较贵的，某宝上要200元左右。

既然这么贵，我们就自己画一个，反正这个板子也不复杂。接下来笔者根据世强提供的原理图对其原理进行了分析。这个原理图包括了三个部分：

1、CPT007B核心电路图，包括IC及外围电路；

2、板子唯一标识，采用的是EEPROM；

3，基于CF326-SX0261GM的调试电路。

笔者认为第二部分是无关紧要的，所以直接PASS。至于第三部分通过和世强的FAE沟通，这部分可以通过世强的USB Debug Adapter来替代实现。

接下来就是画图了，下图是笔者根据官方原理图修改的：

从原理图分析有几个部分组成：

1、触摸按键；

2、输出状态指示灯；

3、蜂鸣电路；

4、电源部分；

5、调试电路和复位电路复用。

为了更方便的配置触摸按键的数量，触摸电容按键和CPT007B之间加了0R电阻；输出状态指示灯采用共阳极供电方式，当有输出的时候，OPT007B输出低电平，LED点亮；蜂鸣器采用的是有源蜂鸣器。调试电路中的CLK脚与复位电路复用，并上拉2K电阻。技术手册明确说明要在CPT007B的VCC引脚加入一个0.1uf电容和一个4.7uf电容，并且这两个电容要尽量靠近芯片。触摸按键的设计比较重要，由于文章篇幅限制，我们另起文档做重要说明。

接下来是原理图布局，下图是笔者的布局：

笔者为了将LED等放在了各自按键的上面，由于触摸按键位于BOTTOM layer，且这一面为了贴合产品面板，应无凸起的元器件，故将LED封装进行了改造，进行了挖空设计，使得LED焊接面在TOP layer，显示面在bottomlayer，封装图如下：

由于这个板子不属于高速板，且电路较为简单，布局和走线方面也没什么太多需要注意的，在板子成型后，笔者加入了具有自己印记的二维码，下图是3D效果图，待样板回来后，在给大家欣赏成品。
