Python Raspberry Pi library for the STEP/DIR stepper drivers.

There are currently 3 distinct driver implementations:

stepdir.StepperDriver Basic step/dir driver No ramping support All drivers not listed below inherit from this one.

tmc26x.TMC26XStepper No ramping support

accelstepper.AccelStepper A port of the Arduino AccelStepper library. Supports configurable ramp profiles. profiles.accel.AccelProfile The original AccelStepper profile profiles.max.MaxProfile A simple profile that accelerates and decelerates as fast as possible.

TMC 260/261/262/2660 Stepper library for Python

Based on the Arduino TMC26X Stepper Motor Controller Library https://github.com/trinamic/TMC26XStepper

pip install spidev

from RaspberryPiStepperDriver import spi, tmc26x

spi_dev = spi.SPI(bus=0, device=0)

driver = tmc26x.TMC26XStepper(spi_dev, 200, 23, 18, 300) driver.start()
