Stepper Motor A4988 Driver Example

No code here - use a quadrature encoder to rotate a single step

Depends on the encoder clock signal driving STEP
while the DATA signal indicates direction 

 A4988:   DIR| STEP
 Encoder: CLK| DT
           0 | 0
           1 | 0
           1 | 1
           0 | 1
