[simpits-tech] Arduino, Part Deaux...

Chip has a Si, So, CLK and CS so hopefully that will suffice.

Just noticed that the full 360-degree gauge output has some interesting serial data input requirements. 

Major Gauge (360°)
MSB                                LSB

D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
|Gauge |Quadrant|      Data          |     
|Select|Select  |                    | 

...that should be fun......

Not having looked at the specs, I would recommend using the chip enable 
pin if one is present. That lets you keep common data & clock lines 
across multiple parts. If CE isn't set for the part in question, it'll 
ignore the clock & data lines.
