的主处理器ATMega328P拥有3个定时/计数器,它们分别是Timer0,Timer1和Timer2;它们都通过对来自内部或外部的脉冲信号进行计数的方式完成基本的定时/计数功能以及一些其他的功能。和Timer2是8位定时/计时器,Timer1是16位定时/计数器;下面以Timer2为例讨论定时/计数器子系统的典型应用,这些内容同样适用于Timer0和Timer...

If you want to make your Arduino sleep for 1 minute, or for multiple minutes, then it’s quite easy.Take the number of minutes, multiply it by 60 to get the number of seconds, and then multiply it by 1000 to get the number of milliseconds....
3软件系统设计 3.1增量式编码器模拟信号产生设计 增量式编码器输岀正交脉冲信号频率取决于编码器的分辨率N（PPR,Pulse Per Revolution,脉冲数/转）和编码器转速棕（rpm,revolutions per minute，转/分钟）。本文所设计的增量式编码器核心功能为根据不同型号增量式编码器参数产生相应转速频率的模拟正交脉冲信号 。
