how to get advanced control of the CPU ? (frequency, app core)

[nponsard]

Hello, I've been searching in the available functions a way to control the cores, their frequency and start the second core on the esp32-S3 but didn't find any function in the libs using idf (I'm intested in being able to use std).

Is there a way to do it ?

For general configuration like default clock speed etc you use the sdkconfig file in your project. All possible keys and there values can be found in the official docu. In this case you can check this option.

You don't need to do anything to use both cores as its the default to use both on every dual core esp variant. The scheduler will move the task/threads appropriately where there is free execution time.

For general question feel free to check out our matrix channel linked in the README
