在Arduino中,delayMicroseconds函数是用于产生微秒级别的延时。详细解释如下:一、delayMicroseconds函数概述 Arduino中的delayMicroseconds是一个用于产生非常短暂延时的函数。这个函数允许你在程序执行过程中暂停一段时间,时间单位微秒,即百万分之一秒。这对于需要精确时间控制的程序非常有用。二、函数的使用方法 ...
用法: delayMicroseconds(microseconds); 其中microseconds 是要暂停的微秒数。 特点: 用于非常短暂的延时,适用于微秒级别的时间控制。 在延时期间,程序同样不执行任何其他任务。 由于这个函数的精度限制,它对于超过几毫秒的延时可能不太准确。 最大延时: 官方文档提到,对于AVR基于8位的Arduino(如Uno, Nano, Mega),最...
Parameters of program functions: for example, in the time function: parameters of the delay function: ms: pause time, the time unit is milliseconds (unsigned long data), delay Microseconds function parameters: us: pause time, the time unit is microseconds (unsigned long data), millis, mircros...
