CircuitPython driver for the TCA9548A I2C Multiplexer.
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
# 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) tsl2 = adafruit_tsl2591.TSL2591(tca) # Loop and profit! while True: print(tsl1.lux, tsl2.lux) time.sleep(0.1)
