FGPIO Peripheral driver

Collaboration diagram for FGPIO Peripheral driver:

This section describes the programming interface of the FGPIO Peripheral driver. The FGPIO driver configures the FGPIO module and provides a functional interface to build the GPIO application.

Function groups

FGPIO Configuration

This function group configures the FGPIO pin.

FGPIO Output Operations

This function group sets the FGPIO pin output, such as write, set, clear, and toggle.

FGPIO Input Operations

This function reads the FGPIO pin value.

FGPIO Interrupt

This function group checks or clears the FGPIO pin interrupt.

Typical use case

Output Operation

/* Output pin configuration */
gpio_pin_config_t led_config =
{
    kGpioDigitalOutput,
    1,
};
/*  Sets the configuration */
FGPIO_PinInit(FGPIO_LED, LED_PINNUM, &led_config);

Input Operation

/*  Input pin configuration */
PORT_SetPinInterruptConfig(BOARD_SW2_PORT, BOARD_SW2_FGPIO_PIN, kPORT_InterruptFallingEdge);
NVIC_EnableIRQ(BOARD_SW2_IRQ);    
gpio_pin_config_t sw1_config =
{
    kGpioDigitalInput,
    0,
};
/* Sets the input pin configuration */
FGPIO_PinInit(FGPIO_SW1, SW1_PINNUM, &sw1_config);
