Research direction

Start with the Rust sketch in the issue, focusing on the proposed Microseconds type, PinState, and WaveGen trait. Clarify the API and timing semantics for bitbanging and PWM, including repeat behavior and pin toggling. Done means the trait design is agreed and its intended waveform-generation behavior is documented.

Written by the indexing model from the issue text.

Description

I'd like to propose a waveform generation trait. This would be useful for efficient bitbanging, PWM, etc.

I will begin with simple sketch and we will see where it will lead.

pub struct Microseconds(/*What should go here? Maybe `pub u32` is fine?*/);

pub enum PinState {
    High,
    Low,
}

pub trait WaveGen {
    fn generate<I: Clone + IntoIterator<Item=Microseconds>>(&mut self, pin: Pin, initial_state: PinState, delays: I, repeat_count: u32);
}

The implementor should set the pin into state defined by initial_state, then wait for duration specified by item from delays and toggle the pin after each item.

I'd love to implement some drivers for wireless sockets I have.
