STM32做主控端，合泰BS83A02A-4做触控按键，按键长按计时问题

最近用合泰的触摸按键BS83A02A-4做触摸按键，主控端STM32F103收到触控端的按键协议那么就解码，现在解码已经解到了，但是按键长按，长按的计时是从松手后自己开始计时，直到计到长按结束的时间，一直没有查到原因void EXTI2_IRQHandler(void)

一般有长按和短按存在的时候，按键按下后开始计时，在长按计时未到时，检测到按键松开，认为是短按，否则认为是长按。你在捋捋计时的逻辑吧

butterflyspring 发表于 2020-5-27 10:47:03

同意楼上观点，一般长按键都是从按下开始计时，持续监测按下的时间，超过一定时间后判定为长按键。当然这些还需要结合触控器的产品说明来实现的
