点击File-Examples-01.Basics-Blink,加载程序如下:/* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN ...

oldtime=millis(); } } ②外部中断:计数的方法 如图: 假设希望计算A在某一段时间内的脉冲,需要知道何时产生脉冲(脉冲的上升沿在哪里) 因此检测边沿可用外部中断→出现一次下降沿就调用一次中断函数 //外部中断intENC A=2;//电机的编码器A端intENC_B=3;//电机的编码器B端intcount =0;//上升沿(脉冲)数量v...
millis() 返回重启(reset)后所经过的毫秒数。 micros() 返回重启(reset)后所经过的微秒数 温馨提示 通常,我们控制LED灯闪烁都会加上一个delay延时来达到切换亮灭时间长度。但是delay有个缺点就是:在给定的时间间隔内是不能做其他操作,这样对于一些需要...
