esp_rom_gpio_connect_out_signal() function
Combine a peripheral signal which tagged as output attribute with a GPIO.
Arguments
signal_idx
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
Whether to signal to be inverted or not
oen_inv
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.
