Example code building full example using delay

Hello! dyn DelayMs means that we're using dynamic dispatch to specify that we only care about types that implement the DelayMs trait. Usually, implementations of the embedded-hal have types that implement DelayMs via hardware-dependent means like ARM's SysTick or linux's thread::sleep() under the hood. For linux_embedded_hal, I think you've correctly imported the Delay struct. It should be initialized as a mutable binding to an empty struct, e.g.: let mut delay = Delay {}. Then, you should pass a mutable reference to this binding into Bno055's init() function:

let mut delay = Delay {};
// ...
bno055
    .init(&mut delay) // <- here we're passing dyn DelayMs by mutable reference
    .expect("Error initializing the IMU");

For an address issue, you could try to remove a call to with_alternative_address() for it to probe a default address. And could you please share an i2cdump's output that you're getting for 0x28 and 0x29 addresses?

Hope this will help!

Added an init example into docs in #12.

Ah, thank you! Knowing the right way to implement the Delay struct was helpful, since it helped to eliminate one of my unknowns, and I think I have it figured out. I'm not particularly used to the way that dynamic dispatch works, so thought the empty instantiation was just standing in for environment-specific code I had to implement.

If it's helpful for anyone else, I've created a new repository with my (now working) code sample for the Odroid-C4 board at https://github.com/ucsb-coast-lab/read_bno055 , which also has a reference for the Adafruit-library-based Python implementation

Also, it might be worth noting that the most recent version of linux-embedded-hal on crates.io (0.4.0-alpha.0) doesn't play well with the existing code because of some missing trait implementations, so it's probably worth sticking with v0.3 for now.
