24 External Interrupts, individual and group Pin Change Interrupts

Microcontroller register level programming for the ATmega2560

In this video, I show how to configure and write code for the AVR external interrupts, covering both the 8 individual interrupts (INT0, INT1, etc.) and 24 Pin Change Interrupts (PCINT). You'll learn how to configure and use these interrupts efficiently in your embedded projects, along with practical coding examples in C for AVR microcontrollers.

In this video, I break down how external interrupts work on the AVR microcontroller, including both the 8 INTx (individual) and 24 PCINTx (pin change) interrupts. I show how to configure and write code for both the two types of interrupts (along with practical coding examples in C for AVR microcontrollers)
✅ What are external interrupts and why are they important
✅ Difference between INTx and PCINTx interrupts
✅ How to configure and use interrupts in AVR
✅ Real AVR C code examples, explaining the register setup

📌 Perfect for students, hobbyists, and anyone working with ATmega microcontrollers (like the ATmega2560).
