interrupt 可以被中断的代码 nointerrupt 可以被中断的代码 外部中断: attach interrupt(interrupt,function,mode) 1)interrupt:中断号,UNO只用0,1,即代表D2,D3口 2)function:调用中断函数,中断发生时调用的函数 3)mode:中断触发模式 UNO R3支持四种模式 low 当针脚输入为低时,触发中断 change 当针脚输入发生变化...
在Arduino世界中,Servo库在Arduino Uno上使用timer1(Arduino Mega上的timer5)。 定时器2: Timer2是一个8bit定时器,在Arduino工作中,tone()函数,IRremote库文件使用timer2。 Timer3,Timer4,Timer5: 定时器3,4,5仅适用于Arduino Mega主板。 这些定时器都是16位定时器。 三、定时器配置代码 AI检测代码解析 int ...
2) 接下来就是中断程序,网上很多写中断的例子,我都试过但失败了,最后去查看interrupt.h才找到中断程序的定义使用(仅限Arduino IDE),格式: ISR(中断向量){ 中断程序; } 代码如下: AI检测代码解析 ISR(TIMER1_OVF_vect){ // TIMER1_OVF_vect是中断溢出向量,不同芯片具体定义还是要去头文件定义和技术文档查看...

Different types of Arduino board have different numbers of interrupts pins e.g. Arduino UNO have two interrupt ports and Arduino Mega2560 have six interrupt ports named as INT1,INT0. On the software side create sleep mode for Arduino and use a timer base interrupts which would internally be ...
