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

    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.
