Configurations
==============
ihm07m1_b16:
------------
These examples are dedicated for the X-NUCLEO-IHM07M1 expansion board
based on L6230 DMOS driver for three-phase brushless DC motors.
X-NUCLEO-IHM07M1 must be configured to work with FOC and 3-shunt
resistors. See ST documentation for details.
Pin configuration for the X-NUCLEO-IHM07M1 (TIM1 configuration):

Current shunt resistance = 0.33
Current sense gain = -1.53 (inverted current)
Vbus sense gain = 9.31k/(9.31k+169k) = 0.0522124390107
Vbus min = 8V
Vbus max = 48V
Iout max = 1.4A RMS
IPHASE_RATIO = 1/(R_shunt*gain) = -1.98
VBUS_RATIO = 1/VBUS_gain = 19.152
For now only 3-shunt resistors configuration is supported.
