General Purpose Input Output (GPIO) is a flexible software-controlled digital signal. Micro-processors heavily rely on GPIOs with only the BIOS firmware knowing how they're used. This paper aims at developing a GPIO library to enumerate all GPIOs’ configuration status and to create a stand-alone user application, which helps a user to configure the GPIO pins without diving into BIOS firmware. UEFI specifications are followed and EDKII is used.
