ESP32-S3-DevKitC-1 : Is there any ESP-IDF API functions in order to configure the clocks and GPIOS ?

Good afternoon,

I would like to know if there are ESP-IDF API fucntions that can be used in order to configure the clocks
on a ESP32-S3-DevKitC-1 board ?

The same thing for the GPIO please ?

Best regards

The same way, I have just read the Interrupt Matrix chapter...
Are they any ESP-IDF API functions that can be used to configure the Interrupt matrix
more easily please ?

Best regards

For clocks: there's a bunch of menuconfig options to set the clock speed and enable dynamic frequency switching.

For GPIO: you have the GPIO driver and generally all other drivers allow you to specify which GPIOs to use, which is an abstraction over the GPIO matrix

For interrupts: esp_intr_alloc handles those for you, but again, most drivers do this internally in order to work as a blocking API externally.
