#include <stm32f401re_gpio.h>
Detailed Description
Configuration structure for initializing a GPIO pin.
Passed to gpio_init. Fields that are irrelevant for the selected mode are ignored:
- output_type, output_speed are only relevant for output and alternate function modes.
- alternate_function is only relevant for GPIO_MODE_ALTERNATE_FUNCTION.
- interrupt_trigger is only relevant for GPIO_MODE_INTERRUPT.
