这时候就是定时器(Timer)和中断(Interrupt)的用武之地了。 Arduino UNO有三个timer timer0 -一个被Arduino的delay(),millis()和micros()使用的8位定时器 timer1 -一个被Arduino的Servo()库使用的16位定时器 timer2 -一个被Arduino的Tone()库使用的8位定时器 "Arduino Mega"板有另外三个可使用的timer3,4...
1、Arduino的定时器中断当你想让代码在一个固定的时间间隔后执行时,你可以很容易的用delay()函数来实现。但是,这只是让程序暂停一个特定的时间段。特别是如果你需要同时让处理器做其他处理时,这么做同时也是一种浪费。这时候就是定时器(Timer)和中断(Interrupt)的用武之地了。Arduino UNO有三个timertimer0 - 一...

This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers...
This library enables you to use Interrupt from Hardware Timers on an Arduino or Adafruit AVR board, such as Nano, UNO, Mega, AVR_FEATHER32U4, etc.As Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to 16 ISR-based Timers, while ...
