extended.rs

//! # Example: Extended (Extended Protocol Controller)
//!
//! Demonstrates the `ExtendedRemoteController`, which supports additional commands such as
//! incrementing motor speed, braking, toggling addresses, and more. In this example, we
//! first increment the speed, and then brake the red output on Channel One.
//!
//! **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 extended --features cir
//! ```
