In the realm of productivity and gaming, macro pads have emerged as versatile tools that can enhance workflow and provide quick access to commands. With the Raspberry Pi Pico, a compact microcontroller board, creating your own custom macro pad is an exciting and rewarding project. This article will guide you…
An interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. When an interrupt is received, the current execution of the program is paused, and control is transferred to a special routine called an “interrupt handler” or “interrupt service routine” (ISR). Once the ISR has finished executing, the processor resumes the program from where it was interrupted.
A state machine is a computational model that outlines how a system behaves in various states based on inputs. It consists of a defined set of states, transitions between those states, and events that trigger those transitions. This model is particularly useful in programming for managing complex system behaviours clearly and efficiently.
