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 ...

Interrupts are used to handle events that do not happen during the normal execution of a program, but when a specific trigger occurs. For example, if we write a program to blink an LED, the ...

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 ...

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...

Consider a simple digital watch which is programmed to just show you time, now imagine you want to change its time zone. What would you do? You simply press a button ...

An ideal C++ device driver would be a class containing, among other things, the ISR as a member function. But this is harder to achieve than many C programmers assume. One of the goals of a recent ...

Digital interrupts represent one of the main concept used in modern computers and embedded systems. In this lab, we’ll explore close the usage of this concept in a real-life situation using one of the ...
