Project description

Introduction

Documentation Status Discord Build Status

CircuitPython driver for the TCA9548A I2C Multiplexer.

Dependencies

This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-tca9548a

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

sudo pip3 install adafruit-circuitpython-tca9548a

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-tca9548a

Usage Example

# This example shows using two TSL2491 light sensors attached to TCA9548A channels 0 and 1.
# Use with other I2C sensors would be similar.
import time
import board
import busio
import adafruit_tsl2591
import adafruit_tca9548a

# Create I2C bus as normal
i2c = busio.I2C(board.SCL, board.SDA)

# Create the TCA9548A object and give it the I2C bus
tca = adafruit_tca9548a.TCA9548A(i2c)

# For each sensor, create it using the TCA9548A channel instead of the I2C object
tsl1 = adafruit_tsl2591.TSL2591(tca[0])
tsl2 = adafruit_tsl2591.TSL2591(tca[1])

# Loop and profit!
while True:
    print(tsl1.lux, tsl2.lux)
    time.sleep(0.1)
