HAL Component — BLDC_HALL3V2

INSTANTIABLE COMPONENTS — General

All instantiable components can be loaded in two manners

Using loadrt with or without count= | names= parameters as per legacy components
Using newinst, which names the instance and allows further parameters and arguments
primarily pincount= which can set the number of pins created for that instance (where applicable)

NAME

bldc_hall3v2 — 3-wire BLDC motor driver using Hall sensors and trapezoidal commutation.

SYNOPSIS

The functionality of this component is now included in the generic "bldc" component. This component is likely to be removed in a future release

USAGE SYNOPSIS

The functionality of this component is now included in the generic "bldc" component. This component is likely to be removed in a future release

DESCRIPTION

This component produces a 3-wire bipolar output. This suits upstream drivers that interpret a negative input as a low-side drive and positive as a high-side drive. This includes the Hostmot2 3pwmgen function, which is likely to be the most common application of this component.

FUNCTIONS

bldc_hall3v2.N.funct ( OR <newinstname>.funct (requires a floating-point thread) )

Interpret Hall sensor patterns and set 3-phase amplitudes

PINS
