ESP32 Forum

Good afternoon,

The Espressif products are totally new for me. I have just installed Eclipse IDE and ESP-IDF 4.4 framework.
I managed to create a new project based on a example and when I open it, I can see a lot of functions which seem to
be part of an API.

For example :
These ones are extracted from the Hello World project :
- esp_chip_info()
- esp_restart()
These one are extracted from the Blink project :
- pStrip_a = led_strip_init(CONFIG_BLINK_LED_RMT_CHANNEL, BLINK_GPIO, 1);
- pStrip_a->set_pixel()...

Could you please tell me if these functions are related to an API ? Is it an ESP-IDF API or somethink like that ?
If the answer is yes, are there functions in this API that can be used to configure every component of the chip ?
Are there documents where the API is explained ?

Moreover, are there drivers for ESP32-S3 chip that can be used in order to develop more easily/quickly (For example USB drivers...) ?

Thank you for your answer.
Best regards.

I think you want to take a look at the esp-idf documentation as it likely has all the answers you need.
