| 中文摘要: |
| 电容式触摸按键技术由于电路相对简单,硬件成本较低,已在各类电子产品中得到了广泛应用。文章主要介绍了一种利用电容分压器(CVD)实现快速触摸感应的方法。首先从电容式感应按键的原理出发,阐述了采用电容分压器实现触摸感应的原理,提出了一种利用CVD实现电容触摸感应技术的硬件电路与软件设计方案。 |
| 英文摘要: |
| Capacitive touch control technology is widely used in many kinds of electronic products,because of the relatively simple circuit,low cost hardware.This paper mainly described a touch-sensitive method called Capacitive Voltage Divider (CVD) which uses no external components.From the principle of capacitive sensitive,it expounded the principle of CVD,and puts forward a touch sensitive technology scheme based on CVD,which mainly included the hardware and software design. |
