Detailed Description

STM32 GPIO specific flags.

The driver flags are encoded in the 8 upper bits of gpio_dt_flags_t as follows:

• Bit 8: Configure a GPIO pin to power on the system after Poweroff.
• Bit 10..9: Configure the output speed of a GPIO pin.

Macro Definition Documentation

STM32_GPIO_HIGH_SPEED

#define STM32_GPIO_HIGH_SPEED   (0x2 << STM32_GPIO_SPEED_SHIFT)

#include <zephyr/dt-bindings/gpio/stm32-gpio.h>

Configure the GPIO pin output speed to be high.

STM32_GPIO_LOW_SPEED

#define STM32_GPIO_LOW_SPEED   (0x0 << STM32_GPIO_SPEED_SHIFT)

#include <zephyr/dt-bindings/gpio/stm32-gpio.h>

Configure the GPIO pin output speed to be low.

STM32_GPIO_MEDIUM_SPEED

#define STM32_GPIO_MEDIUM_SPEED   (0x1 << STM32_GPIO_SPEED_SHIFT)

#include <zephyr/dt-bindings/gpio/stm32-gpio.h>

Configure the GPIO pin output speed to be medium.

STM32_GPIO_VERY_HIGH_SPEED

#define STM32_GPIO_VERY_HIGH_SPEED   (0x3 << STM32_GPIO_SPEED_SHIFT)

#include <zephyr/dt-bindings/gpio/stm32-gpio.h>

Configure the GPIO pin output speed to be very high.

STM32_GPIO_WKUP

#define STM32_GPIO_WKUP   (1 << 8)

#include <zephyr/dt-bindings/gpio/stm32-gpio.h>

Configures a GPIO pin to power on the system after Poweroff.

This flag is reserved to GPIO pins that are associated with wake-up pins in STM32 PWR devicetree node, through the property "wkup-gpios".
