Basic understanding of microcontroller interrupts

Earlier I’ve made a mistake by referring this tutorial to first AVR family microcontrollers like Atmega8/16/32/64/128. But AVR is being continuously changed with various new tweaks and updates like enhanced pin control or different register names. Since now tutorial will be based on Atmega328 microcontroller which is popular in Arduino boards. So you’ll be able to test all code examples on Arduino as it can serve as general purpose AVR test board with no problem. Understanding Interrupts Probably you won’t be able to find a microcontroller without interrupt capability. These are essential attributes of any modern microcontroller or processor. They may seem confusing and tricky at first glance, but during the time you will find out that normal MCU operation is impossible without interrupts. Interrupts can be compared to real… Continue reading
