esp_rom_gpio_connect_out_signal

Postby ride_dirt » Wed Jul 28, 2021 7:59 pm

I am working through the IDF HFP_AG example and trying to figure out this function:
-esp_rom_gpio_connect_out_signal(GPIO_OUTPUT_PCM_DOUT, PCMDOUT_IDX, false, false);
-esp_rom_gpio_connect_in_signal
There are no comments or any documentation on this function. Does anyone have an idea what exact it does or can help?
Thanks!

I agree that docs for these functions are hard to find. There's comments in the header where these functions are defined, though.
