that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc/en/Reference/attachInterrupt. Rather, your first argument is a pin number of a pin that's supported on that chip (seehttps://github.com/GreyGnome/EnableInterrupt/wiki/Usage#pin--port-...
Also the order of the function execution is (normally) ordered from the lower pin number to the higher. Meaning pin 8 will be checked faster as pin 13 (Arduino Uno). Talking about micro seconds here! You can change the order in the settings. For example by default pin 0-3 have a low...
The Arduino board is based on the Atmel AVR ATmega168 or the ATmega328 microchip. 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. ...

For Uno WiFiRev.2, Due, Zero, MKR Family and 101 boards the interrupt number = pin number. TheattachInterruptdocumentation also specifically says that theattachInterrupt(pin, ISR, mode)syntax isnot recommended. http://forum.arduino.cc/index.php?topic=592249 ...

Arduino Nano-33-BLE Arduino SAM DUE. ATmega4809-based boards such as : Arduino UNO WiFi Rev2, AVR_NANO_EVERY, etc. RP2040-based boards such as RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040, etc. using Earle Philhower's arduino-pico core RP2040-based boards such as Na...
This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers...
Timer1 is a 16-bit timer. In the Arduino world, the Servo library uses Timer1 on Arduino Uno (Timer5 on Arduino Mega).3. Timer2:Timer2 is a 8-bit timer like Timer0. This Timer2 is not available for ATMEGA_16U4, ATMEGA_32U4 boards, such as Leonardo, YUN, ESPLORA, etc. In the...
