sparkfun/qwiic_scmd_py: Python module for the qwiic serial control motor driver

The SparkFun Qwiic Motor Driver SCMD Module provides a simple and cost effective solution for adding Motor Driver capabilities to your project. Implementing a SparkFun Qwiic I2C interface, these sensors can be rapidly added to any project with boards that are part of the SparkFun Qwiic ecosystem.

This repository implements a Python package for the SparkFun Qwiic SCMD. This package works with Python, MicroPython and CircuitPython.

• About
• Installation
• Supported Platforms
• Documentation
• Examples

This python package enables the user to access the features of the SCMD via a single Qwiic cable. This includes driving a single motor, driving two motors and more. The capabilities of the SCMD are each demonstrated in the included examples.

New to qwiic? Take a look at the entire SparkFun qwiic ecosystem.

This Python package supports the following SparkFun qwiic products on Python, MicroPython and Circuit python.

• SparkFun Motor Driver Sensor - SCMD

Note

The listed supported platforms and boards are the primary platform targets tested. It is fully expected that this package will work across a wide variety of Python enabled systems.

The first step to using this package is installing it on your system. The install method depends on the python platform. The following sections outline installation on Python, MicroPython and CircuitPython.

The package is primarily installed using the pip3 command, downloading the package from the Python Index - "PyPi".

Note - the below instructions outline installation on a Linux-based (Raspberry Pi) system.

First, setup a virtual environment from a specific directory using venv:

python3 -m venv path/to/venv

You can pass any path as path/to/venv, just make sure you use the same one for all future steps. For more information on venv click here.

Next, install the qwiic package with:

path/to/venv/bin/pip3 install sparkfun-qwiic-scmd

Now you should be able to run any example or custom python scripts that have import qwiic_scmd by running e.g.:

path/to/venv/bin/python3 example_script.py

If not already installed, follow the instructions here to install mpremote on your computer.

Connect a device with MicroPython installed to your computer and then install the package directly to your device with mpremote mip.

mpremote mip install github:sparkfun/qwiic_scmd_py

If you would also like to install the examples for this repository, issue the following mip command as well:

mpremote mip install --target "" github:sparkfun/qwiic_scmd_py@examples

If not already installed, follow the instructions here to install CircUp on your computer.

Ensure that you have the latest version of the SparkFun Qwiic CircuitPython bundle.

circup bundle-add sparkfun/Qwiic_Py

Finally, connect a device with CircuitPython installed to your computer and then install the package directly to your device with circup.

circup install --py qwiic_scmd

If you would like to install any of the examples from this repository, issue the corresponding circup command from below. (NOTE: The below syntax assumes you are using CircUp on Windows. Linux and Mac will have different path seperators. See the CircUp "example" command documentation for more information)

circup example qwiic_scmd\ex1_qwiic_scmd_basic
circup example qwiic_scmd\ex2_qwiic_scmd_two_motor

Below is a quickstart program to print readings from the SCMD.

See the examples directory for more detailed use examples and examples/README.md for a summary of the available examples.

import time
import sys
import math
import qwiic_scmd

myMotor = qwiic_scmd.QwiicScmd()

def runExample():
	print("Motor Test.")
	R_MTR = 0
	L_MTR = 1
	FWD = 0
	BWD = 1

	if myMotor.connected == False:
		print("Motor Driver not connected. Check connections.", \
			file=sys.stderr)
		return
	myMotor.begin()
	print("Motor initialized.")
	time.sleep(.250)
	
	myMotor.set_drive(0,0,0)
	myMotor.set_drive(1,0,0)
	
	myMotor.enable()
	print("Motor enabled")
	time.sleep(.250)


	while True:
		speed = 20
		for speed in range(20,255):
			print(speed)
			myMotor.set_drive(R_MTR,FWD,speed)
			time.sleep(.05)
		for speed in range(254,20, -1):
			print(speed)
			myMotor.set_drive(R_MTR,FWD,speed)
			time.sleep(.05)

if __name__ == '__main__':
	try:
		runExample()
	except (KeyboardInterrupt, SystemExit) as exErr:
		print("Ending example.")
		myMotor.disable()
		sys.exit(0)
