Input only GPIO as UART RX

[tsctrl]

Hi all,

I would like to request help on how to instantiate or change GPIO input only pin such as GPIO34 as RX similar as when using RX pin on GPIO3 (U0RXD).

Is there anyone that has done this before? Example code are much appreciated.

Thank you.

@ESP_Sprite, can help with the example in idf?

This is a input only pin gpio

See the docs. Just feed in pin 34 for rx and off you go.
