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 e...
example: // Toggle LED on pin 13 each second#include<MsTimer2.h>voidflash(){staticboolean output=HIGH;digitalWrite(13,output);output=!output;}voidsetup(){pinMode(13,OUTPUT);MsTimer2::set(500,flash);// 500ms periodMsTimer2::start();// enables the interrupt.// MsTimer2::stop(); /...
外部中断函数 attachInterrupt(interrupt, , mode) 外部中断只能用到数字IO口2和3,interrupt表示中断口初始0或1,表示一个功能函数,mode:LOW低电平中断,CHANGE有变化就中断,RISING上升沿中断,FALLING下降沿中断。 detachInterrupt(interrupt) 中断开关,interrupt=1 开,interrupt=0 关。 中断使能函数 interrupts() 使能中断...

You'll see blynkTimer Software is blocked while system is connecting to WiFi / Internet / Blynk, as well as by blocking task in loop(), using delay() function as an example. The elapsed time then is very unaccurateWhy using ISR-based Hardware Timer Interrupt is better...
// whenever a variable is used by both, Interrupt and main programm we // need to tell the compiler about it ==> volatile volatile unsigned long int millisekunden; // milli seconds timer unsigned long int last_msg; // char buffer[128]; ...
The algorithm depends only on the function micros() which is an interrupt driven timer. Its accuracy is the same as the accuracy of the timer used in the micros() function i.e. it will have the accuracy of the main system clock. ...

we begin I want to make sure we’re all using the same terms. There are two main categories of interrupts: Hardware and Software. A Hardware interrupt is triggered by something outside of the chip like a button while a Software interrupt is triggered from inside the chip like a timer. ...
