What is a GPIO Controller Windows Driver?
A GPIO (General Purpose Input/Output) Controller Windows Driver is a software component that allows the operating system (Windows) to communicate with the General Purpose Input/Output (GPIO) pins on a device's motherboard or external hardware. GPIO pins are used for sending or receiving digital signals (high or low voltage) to/from external devices like sensors, LEDs, switches, and other peripherals.
On many systems, especially embedded systems or specialized hardware like laptops with certain sensors or custom boards, the GPIO controller driver manages how these pins interact with software, enabling you to control or read data from various connected hardware devices through Windows.
