i have breadboarded a trial config and so far it works well
Software speed control of a brushless dc (Bldc) motor from Mach3.
Although this build is typically Mach3 related there is no reason it cannot be adapted for use with any machine control software which provides a PWM spindle control output. As an addition, an option has now been added which will enable the interface to manually control outrunner speed without the need for a PWM signal.
