Introduction

MicroPython driver for the TCA9548A I2C Multiplexer based on 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.
from machine import Pin, I2C
import tca9548a
from ssd1306 import SSD1306_I2C

# Create I2C bus as normal
i2c = I2C(Pin(25), Pin(26))

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

# For each sensor, create it using the TCA9548A channel instead of the I2C object
oled1 = SSD1306_I2C(tca[0])
oled2 = SSD1306_I2C(tca[1])

oled1.text("HELLO", 0, 0)
oled2.text("WORLD", 0, 0)

oled1.show()
oled2.show()
