Hello,

I couldn't find in the ESP32 documentation any reference to Is this function obsolete or replaced by : Alternatively where can I found a description and of course the need to use various gpio_pad_xx() functions.

Thanks in advance
Robert

It's a ROM function... i think you need to #include "esp_rom_gpio.h" before you can use it, but it may be that it's renamed to esp_rom_gpio_pad_select_gpio() there (to distinguish it as a ROM function). Note that you probably want to use something like gpio_reset_pin() (or use gpio_config, which also does this as part of the process) as gpio_pad_select_gpio doesn't cover all cases anymore on newer chips.

OK .... I understand it but after some tests despite the fact lack of documentation (with the exception of the one of Kolban)
Thanks
Robert

I've made an internal issue over the lack of documentation, for what it's worth.
