The 7i76 has a (serial controlled) digital potentiometer. You just pass it a
the spindle speed you want and the two resistances change. You wire it exactly
like a potentiometer and send it a number.
The Spinx1 takes a PWM input and does much the same at the output.
Wiring a 7i76 to a spinx1 is unlikely to work.
