AURIX: Stepper Motor actuation - Documentation and resources

HW:
1. AZDelivery Modulo Driver Motore Passo-Passo A4988 Scheda Breakout with Arduino-compatible heat sink including an E-Book!
2. Nema 17 stepper Motor, Longruner stepper motor bipolar 2 to 64oz. in (45NCM) 42 x 40 mm body 4-lead W/1 m cable and connector with mounting bracket for printer 3D hobby CNC LD08
3. 
 

Note: a power supply connector (8 to 35V) and the 68uF electrolytic capacitance on the board have been solded together. DO NOT touch this part... if you reverse the polarity the chondesator explodes!
See the photo with the polarity of the connector between the motor driver and the motor (2B = black wire, 2nd = green wire ....)
From MCU you have to connect 
GND
3.3V
DIR static 0 or 1 --> motor direction
STEP -->  the motor moves one step (1.8°) at each rising edge of the signal (white cable in the figure)
Connect SLEEP and RESET together
