WebNov 12, 2024 · A GPIO 'controller' is a circuit in the MCU that controls the operation of GPIO pins. The term is typically used in sophisticated I/O systems which may need to perform operations independently from the CPU. Simple systems often just have control registers which the CPU writes to for configuring pin direction etc. Share Cite Follow A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit (e.g. MCUs/MPUs) board which may be used as an input or output, or both, and is controllable by software. GPIOs have no predefined purpose and are unused by default. If used, the purpose and behavior of a GPIO is defined and implemented by the designer of higher assembly-level circuitry: the circ…
