delay - 语法 delay (ms) ; 1. 其中, ms 是暂停的时间(以毫秒为单位)(无符号长)。 delay - 示例 /* Flashing LED * --- * Turns on and off a light emitting diode(LED) connected to a digital * pin, in intervals of 2 seconds. * */ int ledPin=13; //LED 连接到数字引脚 13 void s...
Arduino delay()函数Arduino 时间函数delay()函数的工作方式非常简单。它接受单个整数(或数字)参数。此数字表示时间(以毫秒为单位)。当程序遇到这个函数时,应该等到下一行代码。然而,问题是,delay()函数并不是让程序等待的好方法,因为它被称为阻塞(blocking)函数。
* Turns on and off a light emitting diode(LED) connected to a digital * pin, in intervals of 2 seconds. * */ int ledPin = 13; // LED connected to digital pin 13 void setup() { pinMode(ledPin, OUTPUT); // sets the digital pin as output } void loop() { digitalWrite(ledPin,...
#include <unistd.h> void sleep(unsigned int seconds) { usleep(seconds * 1000000); // usleep使用微秒作为单位 } 区别 1. 实现方式: • delay通常是通过空循环实现的,占用CPU资源。 • sleep通常是通过操作系统的休眠机制实现的,释放CPU资源。 2. 精度: • delay的精度受限于系统时钟和空循环的执行...
'delay for' 表示将某事件或操作的执行时间推迟特定时长,其核心功能是为流程控制或时间管理提供明确的时间间隔设定。该短语在不同领域的使用方式存在显著差异,下文从语义解析、应用场景、技术实现三个维度展开说明。 一、语义解析与语法结构 'delay for' 由动词 delay 和介词 for 构成,后接时...
