A CircuitPython/Python library for Benewake's TF mini distance sensor

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>_.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-tfmini/>_. To install for current user:

.. code-block:: shell

pip3 install adafruit-circuitpython-tfmini

To install system-wide (this may be required in some cases):

.. code-block:: shell

sudo pip3 install adafruit-circuitpython-tfmini

To install in a virtual environment in your current project:

.. code-block:: shell

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-tfmini

Usage Example

.. code-block:: python

import time
import board  # comment this out if using pyserial
import busio  # comment this out if using pyserial
import adafruit_tfmini

# Use hardware uart
uart = busio.UART(board.TX, board.RX)

# Or, you can use pyserial on any computer
#import serial
#uart = serial.Serial("/dev/ttyS2", timeout=1)

# Simplest use, connect with the uart bus object
tfmini = adafruit_tfmini.TFmini(uart)

# You can put in 'short' or 'long' distance mode
tfmini.mode = adafruit_tfmini.MODE_SHORT
print("Now in mode", tfmini.mode)

while True:
    print("Distance: %d cm (strength %d, mode %x)" %
	  (tfmini.distance, tfmini.strength, tfmini.mode))
    time.sleep(0.1)
