PWM0输出500K方波信号 采集按键数据变化 根据按键数据量变化范围确定是否有按键,PWM输出500KHZ方波信号
对电容进行充放电,当手指触摸到金属件 电容参数发生变化,从而电压发生变化,利用AD功能检测变化量,就知道有按键
触摸按键有电阻和电容之分-PWM0 output 500 k square wave signal acquisition button data changes According to the key data volume range to determine whether there is a button, PWM output 500 KHZ square wave signals
To charging and discharging of capacitance, when a finger touch the metal parts Capacitance parameter changes, thus the voltage changes, using AD function detecting variation, knew with keys
Touch the button has the branch of resistance and capacitance
