0/25/2011 Using I am looking for an example on how to configure and use the internal timer interrupts of the 2560. I need to do something similar to the MsTimer2 which is increased on every interrupt, helps me to determine whether I need to read any sensor in this interrupt or not. For example, I

Arduino Mega Interrupts - ArduinoForumde

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.

Arduino Timer Interrupts: Timer interrupts allow you to perform a task at very specifically timed intervals regardless of what else is going on in your code. Diecimila, Nano. . . ). The main ideas presented here apply to the Mega and older boards as well, but the setup is a little different and the table below is specific to ATMEL 328/168

Arduino Playground - Interrupts

Using timers on an Arduino Mega 2560. Ask Question 0. I'm an amateur and I wish to use timers in my project. I'm using an Arduino Mega 2560 with a touch-sensitive screen with six DS18B20 temperature sensors and a DS1307 RTC (real time clock). I would like to query my sensors every 1 or 2 minutes to refresh the screen for temperature acquisition.

Arduino Timer Interrupts. The Mega boards have Timers 3,4,5 which may be used instead. In the example that follows, we shall use Timer1 for our interrupt. Obviously, if you are using the Servo Library there will be a conflict, so you should choose another timer. /* Example Timer1 Interrupt Flash LED every second */ #define ledPin 13 int
