我需要确定Arduino履行某种职能的速度。
这样做的最佳时机是什么? 到目前为止,我发现了一些有“停止监视”的阶层,但我很想知道,是否有本土的方法这样做。
一种直截了当的方式是使用<代码>millis(或micros(功能在Arduino图书馆。 http://arduino.cc/en/Reference/Micros” rel=“noretinger”>micros(。
例如:
unsigned long start = micros();
// Call to your function
myFunction();
// Compute the time it took
unsigned long end = micros();
unsigned long delta = end - start;
Serial.println(delta);
仔细阅读micros(:有一些关于时间解决的信息。
侵扰性最小的办法是,在停电之前将港口置于高位位置,随后则低空。 停泊在港口平线上,测量时间。
这还可以使你对执行时间的多变性有一个良好的定性想法,激发了不断上升的对冲,并看到itter子落在边缘。
