from esp_rom_gpio.h:76

void esp_rom_gpio_connect_out_signal(uint32_t gpio_num, uint32_t signal_idx, bool out_inv, bool oen_inv);

Implemented in esp_rom_gpio.c:15

Arguments

Argument

Declared as

Description

gpio_num

uint32_t

GPIO number

signal_idx

uint32_t

Peripheral signal index (tagged as output attribute). Particularly, `SIG_GPIO_OUT_IDX` means disconnect GPIO and other peripherals. Only the GPIO driver can control the output level.

out_inv

bool

Whether to signal to be inverted or not

oen_inv

bool

Whether the output enable control is inverted or not

Notes

There's no limitation on the number of signals that a GPIO can combine with. Internally, the signal will be connected first, then output will be enabled on the pad.
