How to use the gpio example for deep sleep

[agualuso]

Hello everyone, basically im trying to wake up the board using gpio. Right now im using two buttons but if possible the goal is to use one to wake up and put sleep.
This is what i got so far by using the gpio example

Hi,
The first parameter of `esp_sleep_enable_ext1_wakeup` is the rtc_gpio pin mask, not the rtc_gpio number.
```
else if(io_num == GPIO_INPUT_IO_1){
printf("Wake up\n");
gpio_set_level(GPIO_INPUT_IO_1, 0);
esp_sleep_enable_ext1_wakeup(0x1 << GPIO_INPUT_IO_1, 0);
}
````
