摘要
针对传统的机械按键易损坏,使用寿命短等缺点,采用赛普拉斯公司基于ARM Cortex-M0的PSoC 4系列MCU,设计了一款电容式触摸按键控制的汽车室内阅读灯。首先介绍了电容式触摸按键的基本原理,然后阐述了系统的基本功能,给出了硬件设计原理图及软件设计流程图,最后结合触摸按键的特点给出在线调试参数的基本方法。基于电容式触摸按键的汽车室内灯,简单实用,使用寿命长,提升了用户的体验。
As traditional mechanical button has the disadvantages of vulnerable and short life, a capacitive touch button automobile reading lamp based on Cypress ARM Cortex-M0 PSoC 4 was developed. Firstly, the basic principle of touch sense button was introduced. Then the basic function of the system was described, and the hardware schematic diagram and the software flow chart were presented. Lastly, the basic way of on-line debugging was given. The design of capacitive touch button based interior reading lamp is simple, and enhances service life and userg experience.
