what is %lu in the code means?

In reply to Oleg.

For this guide we are using ESP-IDF v5.5.3, can you try with that version?

(we are not using Arduino Core)

Rui

Report changed, but code still not compiling successfully. I using Arduino core for the ESP32 family of SoCs 3.3.7 (last release).

47 | .pull_down_en = GPIO_PULLDOWN_DISABLE,
| ^~~~~~~~~~~~
exit status 1

Compilation error: request for member ‘pull_down_en’ in ‘GPIO_PULLUP_ENABLE’, which is of non-class type ‘gpio_pullup_t’

In reply to Oleg. In the Configure Button GPIO part of the code... Can you change from this:

gpio_config_t io_conf = {
    .intr_type = GPIO_INTR_POSEDGE, // Rising edge interrupt trigger
    .mode = GPIO_MODE_INPUT,
    .pin_bit_mask = (1ULL << BUTTON_GPIO),
    .pull_down_en = GPIO_PULLDOWN_DISABLE,
    .pull_up_en = GPIO_PULLUP_ENABLE
};

To the following:

gpio_config_t io_conf = {
    .pin_bit_mask = (1ULL << BUTTON_GPIO),
    .mode = GPIO_MODE_INPUT,
    .pull_up_en = GPIO_PULLUP_ENABLE
    .pull_down_en = GPIO_PULLDOWN_DISABLE,
    .intr_type = GPIO_INTR_POSEDGE, // Rising edge interrupt trigger
};

Does it remove that compilation error? Which ESP-IDF version are you using? Please let me know the results. Regards, Rui
