摘要
电容式触摸按键技术由于电路相对简单,只需一个微处理器和一些外围电路就可实现对按键的触摸检测和控制,因而适用于许多家用电器。通过对现有电容式触摸控制电路的分析,本着降低成本和提高可靠性的原则,进行软硬件协同设计,完成低成本电容式触摸控制设计。
Capacitive touch control technology is widely used in many home appliances because of comparatively simple circuit, e.g. just one micro controller and some other peripheral circuits. To reduce the cost and improve the reliability, this paper analyzes the existing capacitive touch control circuit, designs both hardware and software for low cost capacitive touch control.
