(using DA Mellis' support files). The library enables you to assign an interrupt to pins on your chip that support them, and presents a common interface to all supported chips. This means that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc...
You can change the order in the settings. For example by default pin 0-3 have a low priority order than pin 4-7 (Arduino Uno). Because they are used for Serial and normal PinInterrupts. I don't expect anyone to use those pins at all with PCINT but at least the priority is lowered...
The Arduino functionsattachInterrupt() anddetachInterrupt() can only be used for external interrupt pins. These are different interrupt sources, not discussed here. Timer interrupts A timer can generate different types of interrupts. The register and bit definitions can be found in the processor data ...

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...
We expect to be able to use the attachInterrupt(digitalPinToInterrupt(pin), ISR, mode) syntax, even when the use of digitalPinToInterrupt is not absolutely necessary due to the interrupts having the same numbering as the pins (e.g. SAMD)...

I created and released a library in C++ that simplifies the creation of this project for the normal user. It is interrupt-based and doesn't block the code. It is very simple and only requires one Arduino UNO and an IR sensor. - GitHub - george10hany77/T
