How do I communicate with the ADT7320 and ADT7420?

 

The ADT7320 has a SPI 4-wire interface and the ADT7420 has an I²C 2-wire
interface.
The sensors will typically complete a conversion every 240ms and update the
temperature register.
The part has 4 operating modes: Continuous conversion, one-shot mode, 1 sample
per second and shutdown. These modes can be selected in the configuration
register.
