在Arduino编程中,延时微秒(microseconds)是一个非常有用的功能,尤其是在需要精确控制时间间隔的场合。下面,我将详细解释延时微秒的概念、提供代码示例、讲解代码各部分的作用、给出使用时的注意事项,以及提供调试和测试的方法。 1. 解释Arduino中延时微秒的概念 延时微秒是指在Arduino程序中暂停执行指定的微秒数(1秒 = 1,000,
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...
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...
cm = (duration/2)/29.155; // Divide duration in half (due to round trip), then convert distance to centimeters (1cm per 29.155 microseconds), assign to cm variable Serial.print(cm); // Print distance in cm to serial monitor Serial.print(“cm”); Serial.println(); delay(100); // ...
pinMode(outPin, OUTPUT); // sets the digital pin as output } void loop() { digitalWrite(outPin, HIGH); // sets the pin on delayMicroseconds(50); // pauses for 50 microseconds digitalWrite(outPin, LOW); // sets the pin off delayMicroseconds(50); // pauses for 50 microseconds }...
