#### 0.3.0 Breaking change
|
||||
|
||||
Version 0.3.0 introduced a breaking change to improve handling the SPI dependency.
|
||||
The user has to call **SPI.begin()** or equivalent before calling **AD.begin()**.
|
||||
Optionally the user can provide parameters to the **SPI.begin(...)**
|
||||
|
||||
|
||||
#### Breakout
|
||||
|

The library is tested with a breakout board with following pins:
