The ATmega32A is capable of triggering External Interrupts using the INT0, INT1 and INT2 pins located at PD2, PD3 and PB2 respectively. Interrupts are triggered by the processor when a certain event ...

Implementations of basic components like timers, LCD displays, external interrupts, and digital pins on the STM32F103R6 microcontroller, demonstrating fundamental embedded system concepts.

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 designing µC-based systems, you often face a situation in which the µC has to respond to an external event happening at an uncertain moment in time. One example is receiving an echo from an object ...

Interruptions aren’t just a staple of our daily lives. They’re also crucial for making computer systems work as well as they do, as they allow for a system to immediately respond to an event. While on ...

Abstract: In today's microprocessors, external interrupts are the only processor resource that has no full virtualization hardware support. Therefore, they create significant overhead in the form of ...

Microcontroller interrupts are one of the big tools in our embedded programming arsenal. They make the chip listen for particular events, and once detected they stop what they’re doing and run a ...

The 8051-compatible microcontrollers are equipped with up to two inputs that may be used as general-purpose interrupts. A simple way to increase the number of interrupt inputs is shown in the figure.

Exceptions and interrupts pause a program in response to an unexpected event in hardware or software. Interrupts are asynchronous events, and exceptions are synchronous events, but the difference ...

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 ...
