ESP32 PullUp- PullDown

[ats3788]

Hallo
How can I switch on the PullUp- PullDown Resistors in the Arduino IDE

[fivdiAtESP32]

When calling the pinMode function specify mode INPUT_PULLUP to enable the internal pullup resistor or specify mode INPUT_PULLDOWN to enable the internal pulldown resistor.

For example, to enable the pullup resistor for GPIO17 do this:

Code: Select all

pinMode(17, INPUT_PULLUP);

To enable the pulldown resistor for GPIO17 do this:

Code: Select all

pinMode(17, INPUT_PULLDOWN);

Note that not all GPIOs on an ESP32 have pullup and pulldown resistors.
