GPIO Driver

Overview

General Purpose I/O (GPIO) driver.

This module provides functions to configure and control GPIO input/output and interrupt behavior.

Usage & Initialization.

This is an example show how to instantiate GPIO Driver with gpio_instance_t.

#include "gpio/gpio.h"
 
#define GPIO_0  (gpio_hwreg_t*)SYSTEM_GPIO_0_IO_CTRL
 
void gpio_init(){
    gpio_instance_t gpio_0 = {
        .hwreg          = GPIO_0,
        .output         = 0x00, // Set GPIO Output pin Value
        .outputEnable   = 0x0E, // Set to Enable GPIO pin as OUTPUT.
    };
    gpio_applyConfig(&gpio_0);
 
}
