Pull Request Details 📖

Description

First PR for unifying the format of module documentation. Used this format:

//! # Peripheral Name (Peripheral Acronym)
//!
//! ## Overview
//! Small description of the peripheral, see ESP-IDF docs or TRM 
//! 
//! ## Configuration
//! Explain how can the peripheral be configured, and which parameters can be configured
//! 
//! ## Usage
//! Explain if we implement any external traits
//! 
//! ## Examples
//! ### Name of the Example
//! Small description of the example if needed
//! ```rust, no_run
//! ...
//! ```
//! ## Implementation State
//! Missing features...

Still a lot of modules to be updated, but this is already a big PR (sorry)

Testing

Built the documentation and ran the doc-tests.
