Interface for ST SpinFamily motor drivers
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.
stspin to your list of requirements and install.
Create a device chain
import time # Used in our example from stspin import ( SpinChain, StCommand, StRegister, StConstant, ) device_chain = SpinChain( total_devices=3, spi_select=(0, 0) )
This assumes the spi device is at 0, 0.
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) motor_main.move(steps=2200) while motor_main.isBusy(): pass motor_main.setDirection(StConstant.DirReverse) motor_main.run(220) time.sleep(3) motor_main.stopSoft()
