Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...

We love interrupts in our microcontroller projects. If you aren’t already convinced, go read the first installment in this series where we covered the best aspects of interrupts. But everything is not ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

Nearly every embedded system uses interrupt service routines (ISRs). If you need to keep track of time, you likely have a timer interrupt that generates a system tick. If you have a USART, you’re ...

Core (or Processor) is heart of any SoC which controls all the operations of modern day chip. In order to extract the maximum performance out of it, generally Interrupt Based Software is written. But ...

Defining device drivers Discussing the difference between architecture-specific and board-specific drivers Providing several examples of different types of device drivers Most embedded hardware ...

In a System-on Chip(SoC),a general interrupt process works as follows: Interrupt is triggered by a certain system event or interrupt source. Interrupt is detected by system’s peripheral module, which ...
