WiringPi is a GPIO hardware control library and embedded hardware interface designed for managing General Purpose Input Output pins on single board computers. It provides a standardized software layer for interacting with hardware registers, facilitating low-latency pin manipulation.
The project includes a GPIO command line interface that allows users to inspect pin states and manage hardware input and output levels directly from the terminal.
It supports embedded hardware prototyping and hardware state monitoring, specifically targeting Raspberry Pi boards to interact with external electronic components. This is achieved through a C-based hardware abstraction that utilizes memory-mapped I/O access to control sensors and actuators within a Linux environment.
