ESP32 Forum

Hello,
I wa reading some code for a esp32-wrover module and i found a couple of calls that i was not able to find any information about what they are:
PIN_FUNC_SELECT
GPIO_PIN_MUX_REG
Can someone point me to the documentation where they are described or tell what they do?
thanks

Hi amadeok,
PIN_FUNC_SELECT is defined in io_mux_reg.h as basically an alias to REG_SET_FIELD defined in soc.h.

Easiest way to look for those definnitions is to search the code in the repository on GitHub and follow the definitions.
