Field Documentation

◆ pad0

uint8_t gpio_conf_sam0::__pad0__

padding

Definition at line 231 of file periph_cpu_common.h.

◆ bits

uint8_t gpio_conf_sam0::bits

the raw bits

Definition at line 197 of file periph_cpu_common.h.

◆ drive_strength

gpio_drive_strength_t gpio_conf_sam0::drive_strength

Drive strength of the GPIO.

Warning: If the requested drive strength is not available, the closest fit supported will be configured instead.

This value is ignored when gpio_conf_sam0::state is configured to GPIO_INPUT or GPIO_DISCONNECT.

Definition at line 216 of file periph_cpu_common.h.

◆ initial_value

bool gpio_conf_sam0::initial_value

Initial value of the output.

Ignored if gpio_conf_sam0::state is set to GPIO_INPUT or GPIO_DISCONNECT. If the pin was previously in a high impedance state, it is guaranteed to directly transition to the given initial value.

gpio_ll_query_conf will write the current value of the specified pin here, which is read from the input register when the state is GPIO_INPUT, otherwise the state from the output register is consulted.

Definition at line 230 of file periph_cpu_common.h.

◆ pull

gpio_pull_t gpio_conf_sam0::pull

Pull resistor configuration.

Definition at line 206 of file periph_cpu_common.h.

◆ state

gpio_state_t gpio_conf_sam0::state

State of the pin.

Definition at line 202 of file periph_cpu_common.h.
