mcp23017

no_std driver for MCP23017 (16-Bit I2C I/O Expander with Serial Interface module)

Basic usage

Include this library as a dependency in your Cargo.toml:

rust [dependencies.mcp23017] version = "<version>" Use embedded-hal implementation to get I2C handle and then create mcp23017 handle:

```rust extern crate mcp23017;

match mcp23017::MCP23017::default(i2c) { Ok(mut u) => { u.inithardware(); u.pinmode(1, mcp23017::PinMode::OUTPUT); // for the first pin u.allpinmode(mcp23017::PinMode::OUTPUT); // or for all pins

    let status = u.read_gpioab().unwrap();
    println!("all {:#?}", status).unwrap();

    let read_a = u.read_gpio(mcp23017::Port::GPIOA).unwrap();
    println!("port a {:#?}", read_a).unwrap();

    match u.write_gpioab(65503){
        Ok(_) => {
            println!("ok").unwrap();
        }
        _ => {
            println!("something wrong").unwrap();
        }
    }
}
Err(mcp23017::MCP23017::Error::BusError(error)) => {
    println!("{:#?}", error).unwrap();;
    panic!();
}
_ => {
    panic!();
}

}; ```
