Interface for ST SpinFamily motor drivers

Project description

ST Spin Family Interface

A Python library for interfacing with ST Spin Family devices, specifically the ST Micro L6470, L6472, L6474, and L6480 ICs.

Currently this project has a single dependency: spidev.

Getting Started

Add stspin to your list of requirements and install.

Create a device chain

import time  # Used in our example

from stspin import (

device_chain = SpinChain(
	spi_select=(0, 0)

This assumes the spi device is at 0, 0.

Create devices

motor_main = device_chain.create_device(0)
motor_secondary = device_chain.create_device(1)

In our example, there are three devices in the chain, and device 0 is furthest along the chain from the controlling IC's MOSI pin.

Run basic commands

motor_main.hiZHard()  # It is good practice to set device into HiZ-State before setting parameters
motor_main.setRegister(StRegister.SpeedMax, 0x022)

while motor_main.isBusy():
