Arduino Mega 2560 interrupt pins and port mapping with

/11/2013The Arduino team have hidden some of the differences between the ATMega328 and ATM2560 so that attaching INT0 using the attachInterrupt function will attach an interrupt to digital pin 2 on both chips even though on the Mega digital pin2 is actually INT4.

How to have unlimited interrupt Pins on your Arduino

The INTERRUPT_PIN should go to pin 2 or 3 on your Arduino UNO (or other 328p based Arduino). For other Arduinos, check this page to find an interrupt capable pin. For our code example we will wire it to pin 2. The LED connected to ANY_PIN is a straightforward circuit.

Arduino Mega ADK Pinout - electroschematicscom

It adds pin change interrupts, giving a way for users to have interrupts drive off of any pin (ATmega328-based Arduinos), by the Port B, J, and K pins on the Arduino Mega and its ilk, and on the appropriate ports (including Port A) on the Sanguino and its ilk.

Appunti su Arduino: interrupts - Michele Maffucci

On the ATmega1280/2560, only ports B, J, F, and K have pin change interrupt capability. These map approximately to pins 10 through 15, 50 through 53, and A6 through A15 (although part of port J is unmapped to Arduino pins, therefore PCINT11 through PCINT15 are unavailable on the Arduino Mega/Mega 2560).

The Problem ( and Solutions ) With Arduino Interrupts

Arduino Pin Change Interrupts. it calls the port’s ISR which must then decide which pin caused the interrupt. So Pin Change Interrupts are harder to use but you get the benefit of being about to use any pin. or a different 8bit chip with more external interrupts like the Arduino mega, which has four. Also, maybe you don’t need to

Disabling interrupts on TX pin on Arduino Mega 2560

Port UART Arduino MEGA sample code //This sample code was written on an Arduino MEGA 2560. //It will allow you to control up to 4 Atlas Scientific devices through 1 serial RX/TX line. //To open a channel (marked on the board as PRB 1 to PRB 4) send the number of the channel, a colon and the command //ending with a carriage return. //1:rCR

External Interrupts - Multi-tasking the Arduino - Part 2

Den Interrupt Vektor, welcher festlegt welcher Pin einen Interrupt generieren kann. Es ist nicht die Nummer des Pins selbst – es ist tatschlich eine Referenz, wo im Speicher der Arduino Prozessor nachsehen muss, um zu sehen, ob es einen Interrupt gibt.

The Arduino Mega 2560 is a microcontroller board based on

Arduino Timer and Interrupt Tutorial. These chips are pin compatible and only differ in the size of internal memory. Both have 3 timers, called Timer0, Timer1 and Timer2. Timer0 and Timer2 are 8bit timer, where Timer1 is a 16bit timer. The Arduino Mega series is based on the Atmel AVR ATmega1280 or the ATmega2560. They are almost

Arduino Playground - PinChangeInterrupt

The Arduino Mega has a few more external interrupt pins available. On the other hand the pin change interrupts can be enabled on many more pins. For ATmega168 /328-based Arduinos, they can be enabled on any or all 20 of the Arduino's signal pins; on the ATmega -based Arduinos they can be enabled on 24 pins.
