The Arduino Mega has six hardware interrupts including the additional interrupts ("interrupt2" through "interrupt5") on pins 21, 20, 19, and 18. You can define a routine using a special function called as “Interrupt Service Routine” (usually known as ISR). ...

On AVR-based development boards, such as the Arduino UNO, you can employ several interrupts in your custom Arduino sketches. Usually, you only use two, which are timer-interrupts and hardware-interrupts. You can learn more about the other types of interrupts and when the microcontroller (MCU)...

I just was browsing through the recent merges in the Arduino core and came across this one: esp8266/Arduino@0a8f2a1 So it seems you have to place the attribute before the function declartion. 👍 1 Domosapiens reacted with thumbs up emoji Domosapiens mentioned this issue on May 26, 20...

this that could be accomplished in a few lines of code. I just feel like it’s easier to debug and control what’s going on. For these reasons, all of the below will use AVR C commands, which can be used regardless of whether you’re using the Arduino boot-loader and IDE or ...
