Hello, i'm trying to use the DSP Library for FFT computation. I've read the online Espressif documentation but it lacks a lot of information. I also followed the example code but i cannot find any explanation about the following functions: - dsps_bit_rev_fc32() - dsps_cplx2reC_fc32() what do they do...

Hello,
i couldn't find on any ESP32-S3 documents the position of the USB OTG ID pin on the pinout, is it managed by the USB OTG controller or can i use any pins managing the USB_CONIDSTS bit in the USB_GOTGCTL_REG by firmware?
Any help is appreciated.
