README
======
The Nucleo-G431RB is a member of the Nucleo-64 board family. The Nucleo-64
is a standard board for use with several STM32 parts in the LQFP64 package.
STATUS
======
2020-06-12: The basic NSH configuration is now functional.
Configurations
==============
ihm16m1_f32 and ihm16m1_b16:
----------------------------
These examples are dedicated for the X-NUCLEO-IHM16M1 expansion board
based on STSPIN830 driver for three-phase brushless DC motors.
X-NUCLEO-IHM16M1 must be configured to work with FOC and 3-shunt
resistors. See ST documentation for details.
Pin configuration for the X-NUCLEO-IHM16M1 (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 = 7V
Vbus max = 45V
Iout max = 1.5A RMS
IPHASE_RATIO = 1/(R_shunt*gain) = -1.98
VBUS_RATIO = 1/VBUS_gain = 16
For now only 3-shunt resistors configuration is supported.
