//! # i2cdev
//!
//! The `i2cdev` crate provides a safe interface for interface
//! with i2c devices under Linux. The API wraps the Linux
//! kernel interface for interacting with i2c in userspace:
//! https://www.kernel.org/doc/Documentation/i2c/dev-interface
//! ```rust,no_run
//! extern crate i2cdev;
//!
//! use std::thread;
//! use std::time::Duration;
//!
//! use i2cdev::core::*;
//! use i2cdev::linux::{LinuxI2CDevice, LinuxI2CError};
//!
//! const NUNCHUCK_SLAVE_ADDR: u16 = 0x52;
//!
//! // real code should probably not use unwrap()
//! fn i2cfun() -> Result<(), LinuxI2CError> {
//! let mut dev = LinuxI2CDevice::new("/dev/i2c-1", NUNCHUCK_SLAVE_ADDR)?;
//!
//! // init sequence
//! dev.smbus_write_byte_data(0xF0, 0x55)?;
//! dev.smbus_write_byte_data(0xFB, 0x00)?;
//! thread::sleep(Duration::from_millis(100));
//!
//! loop {
//! let mut buf: [u8; 6] = [0; 6];
//! dev.smbus_write_byte(0x00).unwrap();
//! thread::sleep(Duration::from_millis(10));
//! dev.read(&mut buf).unwrap();
//! println!("Reading: {:?}", buf);
//! }
//! }
//! ```
