Field Documentation

drive_strength

gpio_drive_strength_t gpio_conf_esp32::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_esp32::state is configured to GPIO_INPUT or GPIO_DISCONNECT.

Definition at line 254 of file periph_cpu.h.

initial_value

bool gpio_conf_esp32::initial_value

Initial value of the output.

Ignored if gpio_conf_esp32::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.
