  ******************************************************************************
+ * Comments by Timo Karppinen
+ * For correct use of the NUCLEO-F401RE with the X-NUCLEO-IHM02A1, 
+ * the solder bridge SB15 on the NUCLEO-F401RE has to be removed / 
+ * Getting started with X-NUCLEO_IHM02A1, page 3/24. = IHM02A1  L6470 nCS
+ *
+ * Set the motor parameters before connecting the motor!!! Supply voltage, 
+ * Maximum motor phase curent and Maximum phase voltage are the most 
+ * important ones. Set as well the step angle - you will set the number of 
+ * steps per revolution. 
+ *
+ * On first tests supply the IHM02A1 voltage from a source where you can set 
+ * the current limit. The limit should correspond the maximum phase current
+ * given in the step motor data sheet. One phase is driven at a time in full
+ * steps. In half steps the current might be double the motor phase current.
