WiringPi/WiringPi

Features

• GPIO Pin Controllers - Provides a comprehensive interface for reading and writing digital signals and managing GPIO pin modes.
• Hardware Interfacing - Acts as a software layer that provides a standardized interface for interacting with physical hardware registers.
• Low Latency Controllers - Ensures faster response times than standard system calls by controlling GPIO pins through direct memory access.
• Hardware Prototyping Frameworks - Facilitates the development of physical computing projects by controlling sensors and actuators in a Linux environment.
• Direct Memory Access - Implements direct memory access to read and write hardware states, bypassing operating system file descriptors for minimal latency.
• Memory-Mapped I/O - Utilizes memory-mapped I/O to map physical hardware registers into the process memory space for direct pin control.
• Raspberry Pi Systems Programming - Implements low-level driver functionality and systems programming specifically for Raspberry Pi GPIO hardware.
• Hardware Abstraction Layers - Provides a standardized hardware abstraction layer to simplify peripheral control via function calls instead of raw register manipulation.
• Command Line Interfaces - Ships a ready-to-run terminal application for inspecting pin states and managing input/output levels.
• Memory Map Generators - Adjusts physical memory offsets based on the processor architecture to ensure correct hardware register targeting.
• Register Configuration Managers - Controls hardware behavior by writing specific bit patterns to memory addresses corresponding to pin configurations.
• Device State Monitoring - Provides real-time tracking of hardware pin modes and electrical status through a terminal interface.
