//! # Example: Direct (Combo Direct Remote Controller)
//!
//! This example demonstrates the `DirectRemoteController` for the Combo Direct
//! protocol, which sets specific states (Forward, Backward, Brake, or Float)
//! on two outputs independently. Here, we run the red motor forward and the blue
//! motor backward, then brake both.
//!
//! **Hardware setup instructions**:
//! See the project README.md at: [https://github.com/azachar/brickbeam#enabling-ir-on-the-raspberry-pi](https://github.com/azachar/brickbeam#enabling-ir-on-the-raspberry-pi)
//!
//! **Usage**:
//! ```bash
//! cargo run --example direct --features cir
//! ```
