Pullup and Pulldown Resistor GPIO ESP32

[flowjmaria]

Hello everyone, I'd to know how to use pull_up and pull_down internal resistor GPIO (ESP32) with "Code C" in flowcode v9. Can anyone help me?

Thanks.

Hello,

You can try this, replacing 0 with the GPIO number you want to add the pull up or pull down to.

Pull Up

Code: Select all

gpio_set_pull_mode(0, GPIO_PULLUP_ONLY);

Pull Down

Code: Select all

gpio_set_pull_mode(0, GPIO_PULLDOWN_ONLY);

Pull Up and Down

Code: Select all

gpio_set_pull_mode(0, GPIO_PULLUP_PULLDOWN);

Turn off again

Code: Select all

gpio_set_pull_mode(0, GPIO_FLOATING);
