Blocking? & Example code

[hoss183]

Hi, thanks for this library, it looks good.

1. It looks like this library is non-blocking, i.e it does not 'wait' for the result, blocking the arduino, like the LT library does. Is that correct?
   I'm currently finding with the LT provided support functions that the arduino is waiting for around 1 second for the SPI to finish.

2. Would it be possible to add some example code?, to give me a better idea of how to implement it.
