from gpio.h:201

esp_err_t gpio_set_pull_mode(gpio_num_t gpio_num, gpio_pull_mode_t pull);

Implemented in gpio.c:270

Arguments

Argument

Description

gpio_num

GPIO number. If you want to set pull up or down mode for e.g. GPIO16, gpio_num should be GPIO_NUM_16 (16);

pull

GPIO pull up/down mode.

Return value

- ESP_OK Success - ESP_ERR_INVALID_ARG : Parameter error

Notes

This function always overwrite the current pull-up/pull-down configurations ESP32: Only pins that support both input & output have integrated pull-up and pull-down resistors. Input-only GPIOs 34-39 do not.
